Abstract:
Management of waste from carbon fibre composites has become a significant societal issue as the application of composite grows across many industries. In this study, carbon fibres (CF) were successfully recovered from cured carbon fibre/epoxy (CF/EP) prepreg under microwave pyrolysis at 450, 550 and 650 °C followed by oxidation of any residual char. The recovered fibres were investigated for their tensile properties, surface morphologies and the elements/functional groups presented on the surface. The chemical compositions of gaseous and oil pyrolysis products were also analysed. The microwave pyrolysis effectively pyrolyzed the epoxy (EP) resin. Char residue remained on the fibre surface and the amount of char reduced as the pyrolysis temperature increased. Compared to virgin fibres, the recovered fibre suffered from a strength reduction by less than 20%, and this reduction could be mitigated by reducing the pyrolysis temperature. The surface of recovered fibre remained clean and smooth, while the profile of elements and functional groups at the surface were similar to those of virgin fibres. The main gaseous products were CO, H2, CO2 and CH4, whilst the liquid product stream included phenolic and aromatic compounds.

Abstract:
Forensic evidence in the form of fibres is recovered in cases involving sexual offenses, assault, murder and road accidents. In the event when a connection between persons is determined, fibres transferred from an offender’s to a victim’s clothing and vice versa are sought for. Colour is the first physico-chemical property verified during forensic analysis. Any colour differences between materials recovered at the crime scene and those originating from a suspect's clothing suggestthat fibres cannot have come from the same source. The aim ofthis article is to introduce the colour-related issues as they pertain to forensic fibre evidence.

Abstract:
In order to make a contribution to the reduction of raw material costs, in the present study the effect of reused cotton fibres on the quality of conventional ring and OE-rotor yarns was investigated. In the yarn production, it three different waste fibres were taken from a cotton yarn production line and blended with primary cotton fibres at five different levels varying from 5% to 40%. In literature, studies have concentrated on the usage of recovered waste fibre in OE-rotor yarn production. However, to date there has been limited extensive and comparative research on the effect of recovered fibre quality on different yarn properties to determine the possibility of high-quality yarn production from reused fibres. In the study, we focused on the effect of different waste types as well as the amount of waste in the blends on the properties of different yarn types.

Abstract:
The purpose of this study was to assess sensory and functional nerve recovery after digital nerve injury in patients with an end-to-end suture (S) or with implantation of a collagen conduit (C) to bridge a nerve gap. Fifteen S and 11 C with a follow-up of 6–36 months and 28 healthy control participants were enrolled. Methods of assessments were quantitative sensory testing, the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), range of motion and the painDetect questionnaire. After both procedures, sensory profiles showed largely recovered function of C and Aδ fibres but severe loss of Aβ-fibre function leading to increased mechanical detection thresholds. There was only minimal allodynia. Severe pain was absent. Patients with conduits reported more functional impairment, especially in work performance, which correlated with the assessed loss of Aß-fibre function. Level of evidence: III

Abstract:
1. The effect of extrusion cooking of a high-fibre cereal product on digestibility of starch, fibre components and phytate in the stomach and small intestine was studied by in vivo digestion in ileostomy subjects, as well as its effect on ileostomy losses of fat, nitrogen, sodium and potassium.2. Seven ileostomy subjects were studied during two periods (each of 4 d) while on a constant low-fibre diet supplemented with 54 g/d of a bran-gluten-starch mixture (period A) or the corresponding extruded product (period B).3. Extrusion cooking, using mild conditions, did not change the content of starch, dietary fibre components or phytate of the bran product, but the phytase (EC 3.1.3.26) activity was lost. During the period using the extruded bran product, there was a significant increase in recovery of phytate-phosphorus (period A, 44% of intake; period B, 73% of intake). The amount of fibre components, fat, fatty acids, N, Na, K, water and the ash weight of the ileostomy contents did not differ between the two periods. Only 0.6 and 0.7% respectively of ingested starch was recovered in ileostomy contents in periods A and B, while the fibre components were almost completely recovered.4. Extrusion cooking, using even mild conditions, may lead to a considerable impairment in the digestion of phytate, probably due to a qualitative change in phytate and a loss of phytase activity. Starch, before and after extrusion cooking, is almost completely digested in the stomach and small intestine while fibre components are digested to a very small extent.

Abstract:
The six natural silicates known as asbestos may induce fatal lung diseases via inhalation, with a latency period of decades. The five amphibole asbestos species are assumed to be biopersistent in the lungs, and for this reason they are considered much more toxic than serpentine asbestos (chrysotile). Here, we refined the atomic structure of an amosite amphibole asbestos fibre that had remained in a human lung for ∼40 years, in order to verify the stability in vivo. The subject was originally exposed to a blend of chrysotile, amosite and crocidolite, which remained in his parietal pleura for ∼40 years. We found a few relicts of chrysotile fibres that were amorphous and magnesium depleted. Amphibole fibres that were recovered were undamaged and suitable for synchrotron X-ray micro-diffraction experiments. Our crystal structure refinement from a recovered amosite fibre demonstrates that the original atomic distribution in the crystal is intact and, consequently, that the atomic structure of amphibole asbestos fibres remains stable in the lungs for a lifetime; during which time they can cause chronic inflammation and other adverse effects that are responsible for carcinogenesis. The amosite fibres are not iron depleted proving that the iron pool for the formation of the asbestos bodies is biological (haemoglobin/plasma derived) and that it does not come from the asbestos fibres themselves.

Abstract:
The demand for textile fibres is growing quickly. However, global cotton production has stabilized around 25 Mton/year. This is a sound development since cotton cultivation causes major sustainable development issues. Even if regenerated cellulose fibre production steadily grows, it is still only from a sixth to a fifth of cotton volumes. Hence, it is essential to find resource-efficient routes to generate alternatives to virgin cotton. There are many promising research initiatives that discover the possibility to utilize waste streams of neat cotton and cotton in fibre blends as raw materials for dissolving pulp for regeneration into, for example, viscose or Lyocell. However, there is a much simpler and energy-efficient route at hand. If fabrics are disintegrated mechanically, the separated fibres can be turned into yarn again. However, since fibre length is a key parameter to accomplish strong and durable textiles, fibre length loss upon tearing should be minimized. This study evaluates how fibre length distribution alters upon tearing of post-consumer cotton waste of two different constructions: denim and single jersey; and different degrees of wear, rendering four different fractions: (1) barely worn denim, (2) rather worn denim, (3) barely worn single-jersey and (4) rather worn single-jersey. Before tearing, the garments were dissembled, their yarns were characterized, fibre length distributions were manually determined for (1)–(4). Length analysis of the recovered fibres after tearing revealed that the length drop was most severe for (a) the finer single-jersey and (b) the barely worn fractions. The findings suggest that significant wear does not exclude from mechanical recycling.

Abstract:
Energy utilization is a determining factor for the standards of living around the world, and the current primary source of energy is fossil fuels. A potential source of liquid fuels that could ease the strain caused by diminishing petroleum resources is bioethanol. Effective exploitation of biomass materials requires a pretreatment to disrupt the lignin and cellulose matrix. The pretreatment utilized for this research was oxygen delignification, which is a standard process stage in the production of bleached chemical pulp. The model substrate utilized as a feedstock for bioethanol was recovered fibre. An analysis of the substrates digestibility resulted in a hexose yield of approximately 23%, which justified the need for an effective pretreatment. An experimental design was performed to optimize the delignification conditions by performing experiments over a range of temperature, caustic loadings, and reaction times. Equations were developed that outline the dependence of various response parameters on the experimental variables. An empirical model that can predict sugar concentrations from enzymatic hydrolysis based on the Kappa number, enzyme loading, and initial fibre concentration was also developed. A study of hydrolysis feeding regimes for untreated recovered fibre (87 Kappa), pretreated recovered fibre (17 Kappa), and bleached pulp (6 Kappa) showed that the batch feeding regime offers reduced complexity and high sugar yields for lower Kappa substrates. In order to evaluate the possibility of lignin recovery, the pH of delignification liquor was reduced by the addition of CO₂ and H₂SO₄, resulting in up to 25% lignin yield. An experiment that looked at effect of post-delignification fibre washing on downstream hydrolysis found that a washing efficiency of approximately 90% is required in order to achieve a hexose sugar yield of 85%.

Abstract:
Les composites renforcés à fibres de carbone (CRFC) sont des matériaux de haute technicité appliqués à de nombreux domaines, du sport à l’aéronautique. Cette dernière décennie a vu leur demande croitre continuellement, générant en conséquence une augmentation du volume de déchets. Incités par les directives Européennes sur la gestion des déchets, des traitements thermiques de recyclage industriel ont été développés afin de récupérer les fibres de carbone issues des CFRC, principalement à matrice thermodurcissable. Actuellement, les CRFC en développement et/ou de dernières générations, utilisent des matrices thermostables telles que le Poly Ether Ether Cétone (PEEK). Une partie des travaux de thèse consiste à étudier la faisabilité de recyclage de ce composite thermostable, seul et en mélange avec d’autres types de composites à matrice thermodurcissable et thermoplastique. Un pilote semi-industriel a été employé sous atmosphères inerte (pyrolyse) et réactives (vapo-thermolyse et air). Les premiers résultats sur des mélanges ont montré que sous atmosphère inerte la récupération des fibres de carbone issues des matrices thermostables est quasi impossible. A l’inverse, les essais sur les composites PEEK en atmosphères oxydantes permettent l’extraction de la fibre mais induisent des modifications morphologiques et chimiques de la surface ainsi qu’une réduction de la résistance en traction. Les travaux de thèse se focalisent également sur des solutions alternatives de valorisation des fibres de carbone recyclées. Ces fibres ont été recouvertes de nanocellulose en tant qu’agent d’ensimage, en vue de leur réutilisation dans de nouvelles formulations. La perte de propriétés mécaniques induite par le recyclage a été partiellement compensée par ce traitement de surface. Des fibres recyclées ont également été incorporées dans un composite à renfort naturel de jute et matrice PA6 dans le but de créer un composite hybride offrant des propriétés équilibrées en termes de résistance, prix et impact écologique
Carbon Fiber Reinforced Composites (CFRC) are high technical materials applied in various fields from sports to aeronautics. During the last decade, the demand of CFRC has extended significantly resulting in increasing the volume of composite waste generated each year. Incited by European directives, thermal recycling treatments have been developed at industrial scale to recover carbon fibers, mostly from thermosetting composites. Nowadays CFRP in development used thermoresistant resins such as Poly Ether Ether Ketone (PEEK). Part of this work is to study the recycling feasibility of this type of CFRP alone and mixed with thermosetting and thermoplastics matrix based composites. Semi-industrial pilot was used in inert (pyrolysis) and reactive (steam-thermolysis, oxydation) atmosphere conditions. First results of mixture perform in nitrogen have revealed that inert atmosphere cannot allow the recovery of carbon fibers from thermoresistant resins. On the contrary trials on PEEK in oxydative atmospheres enable the extraction of fiber, but induce morphological and chemical modifications and tensile strength reduction. New approach on the recycled carbon fiber valorization have also been studied. These fibers have been coated by nanocellulose as sizing agent for their reuse in new composite formulations. Mechanical properties loss induce by recycling have been offset thank to this surface treatment. Recycled fibers was also incorporate in jute/PA6 composite to create a hybrid composite with balance properties in terms of strength, price and environmental impact

Full text
Abstract:
Abstract The amount of printing ink in a pulp suspension produced from recovered paper and its impact on overall brightness is commonly estimated from the reflectance-based ink content measured at a wavelength of 700 nm or 950 nm. The method uses a light scattering coefficient that can be measured from a slightly translucent test medium, i.e. of an opacity less than 97%. This is the case with machine-made papers in most instances. Alternatively, suitable opacity can be achieved by preparing a standard low-grammage sheet on a wire screen, but this results in poor retention of fibre fines, mineral fillers and printing inks, which is especially detrimental to ink measurement when the pulp suspension contains substantial amounts of printing inks. Hence opaque pads are often prepared on filter paper to achieve high retention. Unfortunately their high opacity prevents measurement of the light scattering coefficient, and thus a constant coefficient must be used for the determination of ink content. The aim of this thesis was to clarify the effects of retention and fine material changes on the light scattering coefficient in ink content measurement. The results showed that the light scattering properties of pulp in the wavelength region used for ink content analysis do not remain constant when the fine material content varies. The grade of the recovered paper, hyperwashing and flotation alter the fine material content and thus affect the light scattering. Printing ink also affects light scattering, but its practical impact is smaller than that of fibre fines and mineral fillers. The light scattering coefficient used for each ink content measurement needs to be representative, otherwise a systematic bias in ink content measurements may result from changes in the nature of the fine material and in its content. It is recommended that the light scattering coefficient should be measured in order to avoid this. The measurement should preferably be performed from a low-grammage sheet prepared on filter paper, as this ensures high retention and a measured value that represents better the initial state of the pulp suspension
Tiivistelmä Mustepitoisuusmittaus perustuu hajaheijastukseen joko 700 nm tai 950 nm aallonpituudella ja sitä käytetään usein arvioitaessa keräyspaperista valmistetun massasuspension soveltuvuutta painopaperien valmistukseen ja painomusteen vaikutusta massan vaaleuteen. Mustepitoisuuden mittauksessa käytetään valonsirontakerrointa, joka voidaan mitata hieman läpikuultavasta näytteestä eli näytteen opasiteetin on oltava pienempi kuin 97 %. Tämä opasiteettiraja toteutuu useimmiten paperikoneella tehdyille painotuotteille. Riittävän alhainen opasiteetti saavutetaan myös valmistamalla standardin mukainen matalaneliömassainen arkki viiralle, mutta tämä johtaa kuitumaisten hienoaineiden, mineraalisten täyteaineiden ja painomusteiden alhaiseen retentioon. Matala retentio on erityisen haitallinen piirre mustemittauksen kannalta massoilla, jotka sisältävät huomattavia määriä painomusteita. Siten usein valmistetaan läpikuultamattomia arkkeja suodatinpaperin päälle, joiden retentio on korkea. Korkeasta opasiteetista johtuen näistä arkeista ei voida määrittää valonsirontakerrointa, jolloin mustepitoisuuden määritys perustuu vakiokertoimeen. Tämän väitöskirjan tavoitteena oli selvittää retention ja hienoaineiden muutoksien vaikutuksia valonsirontakertoimeen ja mustemittaustulokseen. Tutkimuksen tulokset osoittivat että valonsirontakerroin, joka mitataan mustepitoisuuden yhteydessä, ei pysy vakiona hienoainepitoisuuden muuttuessa. Hienoainepitoisuuteen ja siten valonsirontakertoimeen vaikuttavat keräyspaperin laji, hyperpesu ja vaahdotus. Myös painomuste vaikuttaa valonsirontakertoimeen, mutta käytännössä vaikutuksen suurusluokka on pienempi kuin hieno- ja täyteaineilla. Mustepitoisuuden määrityksessä käytetyn valonsirontakertoimen on oltava edustava, muutoin arvot voivat olla systemaattisesti virheellisiä hienoainemäärän tai laadun muuttuessa. Virheen välttämiseksi olisi suositeltavaa määrittää valonsirontakerroin mustepitoisuusanalyysin yhteydessä. Tämä olisi mahdollista tehdä suodatinpaperin päälle valmistetusta matalaneliömassaisesta arkista, jolloin saavutetaan korkea retentio ja näin mitattu arvo edustaa paremmin massasuspension alkuperäistä tilaa

Abstract:
This work is concerned with the characterisation and reuse of fibres recovered from end of life thermoset composites by fluidised bed thermal processing. Emphasis is placed on the properties of recovered glass fibres and their reuse in a dough moulding compound and a tissue product. The need for a recycling process is demonstrated by a survey of the market for thermoset composites with particular consideration given to the potential growth in automotive applications. A study of processes developed to recycle such materials and the effect on the structural properties of composites containing such recyclate shows that a process capable of generating recyclate of greater value is required, particularly for the case of contaminated materials. A review of investigations into the effect of prior heat treatment on the mechanical properties of glass fibres shows that their strength will be reduced by a deterioration of the fibre surface during fluidised bed thermal recovery but that their stiffness is likely to be unaffected. The implications of these effects on possible applications for the recovered fibres are described. Tests are reported on the structural properties of laminates containing heat treated glass cloth which show that there is a strength reduction which is both time and temperature dependent but that modulus is not significantly affected. Strength loss increases with up to 20 minutes heating but then remains constant. In some cases the strength loss can be reduced by resizing the cloth. Measurement of the properties of fibres recovered using the fluidised bed process shows that the recovered fibre strength decreases with increasing processing temperature. Glass and carbon fibres recovered at 450°C retain approximately 50% and 80% of their virgin strengths respectively. The Young's modulus of the recovered fibres is shown to be largely unaffected by the process for both glass and carbon fibres. Investigation of the lengths of the recovered glass fibres by image analysis techniques suggests that their distribution depends on the structure of the composite and the method of size reduction. A weighted mean fibre length of 3.5 mm to 5.5 mm is possible with the apparatus described in this thesis. The reduced reinforcement potential of the recovered fibres is confirmed by experiment. Recovered glass fibres are used to displace virgin fibres in a dough moulding compound. At replacement levels of up to 50% there is no significant effect on the mechanical properties of a compression moulded plate. Above this level, tensile, flexural and impact strengths are reduced and with complete replacement the reduction is by approximately 40%, 50% and 70% respectively. These results are confirmed on a pilot plant scale. Recovered glass fibres can be successfully incorporated with virgin fibres into a veil. Replacement of virgin fibres reduces both wet and dry strength because the recovered fibres are both shorter and weaker. The permeability of the veil is found to depend on its porosity and not its recovered fibre content. The experimental veils can be used to protect and improve the surfaces of mouldings.

Abstract:
The objective of this work was to determine the influence of recovered fibres on the mechanical properties of board. Industrial board was provided by Fiskeby Board AB and laboratory board was made by using an isotropic sheet former. Board properties such as tensile strength, tensile stiffness, z-strength and bending stiffness were evaluated. Variation in the grammages of the middle and bottom layers of laboratory board was done and influence on the mechanical properties was studied. Each layer of multiply board was also tested separately at industrial board grammage and standard grammage. Results showed an increase in the tensile properties with the increase in the grammage of bottom layer, an increase in the z-strength of the board was also observed. Bending stiffness calculated by laminate theory also indicated an increase with the increase in the grammage of bottom layer. While testing of the separate layers showed an increase in the tensile properties of the layers with increasing the grammage while a decrease in z-strength was observed. Cracks occurred in the bottom layer of the multiply boards but an increase in the mechanical properties of board was observed.
Returfibrer är miljövänliga och ger ett försprång framför nyfiber på grund av låg kostnad. Det är dock allmänt känt att returfibrer inte uppvisar samma egenskaper som nyfibrer, i själva verket försämras fiberegenskaperna efter varje återvinningsprocess. Mekaniska egenskaper är mycket viktiga för kartongproducenter och därmed läggs en hel del energi på förbättringar utan kostsamma investeringar.   I detta examensarbete utvärderades mekaniska egenskaper för 4-skikts kartong såsom dragstyrka, dragstyvhet, böjstyvhet och z-styrka. Den industriella kartongen som användes kom från Fiskeby Board AB och laboratoriekartong tillverkades med en isotrop arkformer. Separata skikt formades och guskades därefter samman. Ytvikten av det mellersta och undre skiktet ändrades och effekten på kartongens egenskaper utvärderades. Varje lager testades också separat vid ytvikter representativt för den industriella kartongen samt vid standardiserade ytvikter. Styrkan i tjockleksriktningen utvärderades med z-styrka och Scott Bond. Böjstyvheten beräknades med hjälp av laminatteorin.   Skillnaderna i dragstyrka mellan kartong framställd i industrin och laboratorie var små, men dragstyvheten var lägre för laboratoriearken på grund av torktekniken. Skillnaderna i z-styrka var inte signifikanta, men baserat på trenden uppvisade laboratoriearken en lägre styrka på grund av ett lägre presstryck. Delamineringen i de testade proverna skedde i det undre skiktet och inga sprickor uppstod mellan skikten.   Genom ökning av ytvikten av de separata skikten ökade styrkeegenskaper såsom dragstyrka och Scott Bond medan z-styrkan minskade. Genom att minska ytvikten av det mellersta lagret och öka ytvikten av det nedre kunde en ökning av styrkeegenskaperna observeras. Ökningen av z-styrkan var inte signifikant men baserat på trenden kan en ökning förväntas. En betydande ökning av Scott Bond kunde dock ses. Böjstyvheten beräknad genom laminatteorin visade också på en ökning. Även om sprickor fortfarande förekommer i det undre skiktet efter ökning av ytvikten, kan förbättrade kartongegenskaper uppnås.

Abstract:
This work has included a review of the most relevant aspects of measurement techniques and mathematical models proposed in the literature to assess the equilibrium and mass transfer data of metal extraction by the use of chelating agents. The limitations of these techniques and models have been highlighted. Three chelating extractants diluted in EscaidllO were used to study the extraction equilibrium of copper. The extractants are 5-nonylacetophenone oxime (LIX84®), 5- dodeylsalicylaldoxime (LIX860®) and 50/50 v/v mixture of both oximes (LIX984®). The copper concentration changes in the aqueous and the organic phases were monitored by using atomic absorption spectrophotometer. Two mathematical models (a chemical model and a semi-empirical model) have been developed in this study to predict the equilibrium data of copper sulfate/hydroxyoxime system. The chemical model was found to fit all the three equilibrium systems (CuSO4/LIX84®, LIX860®and LIX984®) equally. The semi-empirical model based on Freundlich's adsorption equation was also found to fit the three systems but with less accuracy. The mass transfer characteristics and properties of copper extraction and recovery from an aqueous solution using LIX984® were studied using dispersion-based (rising drops) and dispersion-free techniques. In the dispersion-based technique the organic phase was dispersed in form of drops at the tip of hypodermic needle while the aqueous solution was used as a continuous phase. The extraction process was carried out in four different height columns under wide range of conditions. The effects of the columns' height, the dispersed and the continuous phases concentrations on the metal rate of mass transfer were investigated. It has been found in that the metal's rate of mass transfer and system's overall mass transfer coefficient have remained constant in all four columns. A model utilising the two-film theory, some of the dimensionless groups and the experimental results has been proposed in this work to calculate the local mass transfer coefficients in the dispersed phase and the continuous phase. The overall mass transfer coefficient and the calculated local coefficients were used to account for the reaction rate constant at the interface from the sum of the individual resistances to mass transfer. A dispersion-free technique consisting of a microporous hollow fibre module was used in this study to examine the mass transfer properties of the extraction and stripping processes of copper across an immobilised interface system. The extraction and re-extraction (stripping) processes in this system were conducted under a wide range of operating conditions and produced satisfactory results. In general it has been found that counter current flow arrangement gave higher concentration driving forces which were reflected in form higher metal concentrations at the extract phase. A generalised mathematical model was developed in this study which utilised Wilson's method, the experimental data, some dimensionless groups and the two-film theory to account for local resistances and predict the system's overall mass transfer coefficient. A correlation was established first to calculate mass transfer coefficients using a form of Leveque's equation which relates the two phase's physical properties and the system's parameters. The membrane mass transfer coefficient was calculated from the structural properties of the membrane material. While the resistance at the reaction interface was calculated under set of experimental conditions. The individual coefficients were then used to predict the overall mass transfer coefficient under any set of conditions by using the aditivity approach of the individual resistances to mass transfer. However, further checks and investigations are necessary to validate this model over variety of extraction systems and membrane configurations.

Abstract:
Fire activity, in terms of intensity, frequency, and total area burned, is expected to increase with a changing climate. A challenge for landscape-level assessment of fire effects, often termed burn severity, is that current remote sensing assessments provide very little information regarding tree/vegetation physiological performance and recovery, limiting our understanding of fire effects on ecosystem services such as carbon storage/cycling. In this paper, we evaluated whether spectral indices common in vegetation stress and burn severity assessments could accurately quantify post-fire physiological performance (indicated by net photosynthesis and crown scorch) of two seedling species, Larix occidentalis and Pinus contorta. Seedlings were subjected to increasing fire radiative energy density (FRED) doses through a series of controlled laboratory surface fires. Mortality, physiology, and spectral reflectance were assessed for a month following the fires, and then again at one year post-fire. The differenced Normalized Difference Vegetation Index (dNDVI) spectral index outperformed other spectral indices used for vegetation stress and burn severity characterization in regard to leaf net photosynthesis quantification, indicating that landscape-level quantification of tree physiology may be possible. Additionally, the survival of the majority of seedlings in the low and moderate FRED doses indicates that fire-induced mortality is more complex than the currently accepted binary scenario, where trees survive with no impacts below a certain temperature and duration threshold, and mortality occurs above the threshold.

Abstract:
Cette étude porte sur l'effet de l'ozone introduit en flottation en vue d'optimiser le désencrage des fibres récupérées pour la production de papier de forte blancheur : amélioration des propriétés optiques des fibres recyclées et réduction de l'impact environnemental des rejets du désencrage. Un pilote de flottation couplé à un générateur d'O3 a été développé et validé dans des conditions classiques de flottation à l’air. L'effet de O3 sur l’opération de désencrage a été étudié pour deux types de papiers récupérés (impression offset et mélange 50/50 de journaux/magazines). L’introduction d’O3 en flottation conduit à une amélioration de l’élimination de l’encre, à une légère diminution de la production de boues de désencrage et à la dégradation partielle des azurants optiques ce qui accroît l'aptitude au contact alimentaire de la pâte désencrée. De plus, la DCO des effluents est réduite de plus de 25%. Ces résultats montrent que la flottation réactive à l'O3 est une solution prometteuse pour améliorer l’efficacité du désencrage et diminuer la pollution de ses rejets
This work studied the effect of ozone used as a reactive gas in flotation in order to optimise recovered cellulosic fibre deinking for the production of high brightness paper : improvement of the recycled fibre optical properties and reduction of the flotation rejects. A flotation pilot, coupled with an ozone generator, was developed and validated in the conventional air flotation operating conditions. The effect of ozone on the deinking process was studied for two recovered paper furnishes (offset prints and a mixture of 50/50 newsprints and magazines). The introduction of ozone led to the increase of ink removal, to a slight reduction of the deinking sludge production and to the partial degradation of the optical brighteners which improves the food-contact ability of deinking pulps. Moreover, the COD of the effluents is reduced by more than 25 %. These results showed that the ozone reactive flotation is a promising solution to improve the deinking efficiency and to decrease the pollution of its rejects

Abstract:
Biocrusts and the ecosystem services they provide are becoming more susceptible to fire as exotic annual grass invasions facilitate the spread of desert wildfires. Further, precipitation patterns across the western United States are predicted to change over the next century, and have the potential to dramatically influence fire regimes and the recovery of burned biocrusts. Despite these changes to desert fire and precipitation cycles, our understanding of post-fire biocrust recovery is limited, especially regarding the first two years after fire. To investigate biocrust recovery, we created burn manipulations (i.e., unburned and burned) and tracked crust form and function over two years in one cold and one hot desert ecosystem (UT, USA). We evaluated the entire bacterial community, but focused on Cyanobacteria species that confer soil stability and N fixation capabilities to biocrusts. Specifically, we quantified shifts in biocrust bacterial community composition using target metagenomics of 16S rDNA; monitored biocrust moss and lichen cover; measured N fixation potential; and assessed soil infiltration rates and soil stability. We found little evidence that biocrust form or function recovered from fire within two years. Based on pyrosequencing results, fire altered biocrust community composition in interspace and shrub biocrusts. Cyanobacteria species were almost completely eliminated by fire, constituting 9-21% of unburned plots and less than 0.01% of burned interspace and shrub biocrust communities. Based on cover estimates, no lichen or moss species survived the fire or recovered within two years. N fixation potentials decreased by at least six-fold in burned interspace biocrusts, representing a reduction in soil N inputs into already N-limited desert soils. Soil infiltration rates also drastically declined in burned biocrusts and remained depressed, but only remained depressed for one year. To investigate the interactions between biocrust recovery, fire, and precipitation, we nested precipitation treatments manipulating the amount of monthly rainfall (i.e., ambient, plus 30% and minus 30%) within burn treatments during the second year. Soil NH4+ was the only parameter to be affected by precipitation, and exhibited a positive relationship with precipitation magnitude at the end of one year. Our results demonstrate that fire is a strong destabilizer of the bacterial components of biocrust communities and that the ecosystem services provided by crusts recover at different rates, with N dynamics recovering more slowly than soil ecohydrology.

Abstract:
Abstract Temporary plugging technology are widely used in unconventional exploitation, for it can produce more fracture thus to enhance oil recovery, however, it is still unclear how the plugging is formed and the diverters migrate in the hydraulic fracture. In this work, a self-developed visualization fracture system is set up. And the plugging mechanism of guar-based fracturing fluid with temporary plugging materials is visualized in a rough laboratory-scale fracture. Impacts of parameters on plugging process like particle concentration,fibre concentration, and fracture width are systematically investigated.Through a series of comparative experiments, it is found that the plugging process was triggered by fibre, they form nets to capture particles, then the nets with particles roll bigger and bigger like snowballs,while the nets can not capture particles will be broken in higher pressure. Comparative results indicate that the sealing effect of the same forum for wider fracture will be worse, replacing with the larger particles is more effective than increasing the amount of diverter; Increasing particles can increase sealing strength while increaing fibres can shorten the sealing formation time; Using 1% fiber only, the 3mm-wide fracture can be plugged but it cost much time and the sealing is not so firm. While using 1% particles only, a particle dump forms instead of a sealing layer. For field operation, it is suggested that (1) For wider fracture, use bigger particle is more effective than add more fibre and particles; (2) Particle should be added later than fibre; (3) To increase sealing pressure and enhance efficiency, the ratio of fibre and particles should be around 2:1.

Abstract:
As the need for deployable space structures continues to increase, a deeper understanding of the mechanical properties and the responses of shape memory composites will be needed. Past research efforts have been focused on woven (0/90) carbon fiber composites which limit the shape memory capabilities due to the brittle nature of this fiber. The current work not only utilizes a synthetic fiber which allowed for a greater versatility in the composite, but also investigates the effects of angle plies and fiber volume fraction on the attainable bend ratio of the laminates. Four types of laminates were made to test the effects of laminate thickness, angle-plies, and fiber volume fraction. The specimens from these laminates were placed in both bending and tensile tests to investigate the effect of the fiber reinforcement on the polymer’s stiffness, strength and recovery. Testing revealed that the thicker specimens demonstrated improved recovery over the thinner samples, and that the angle-ply specimens recovered better than the (0/90) specimens. The recovery of the (0/90) specimens was improved by increasing the fiber volume fraction. Most significantly, the specimens were able to achieve smaller bend ratios than in previous studies without fiber microbuckling or fiber breakage. The tensile test data revealed that the bending cycles had little to no affect on the material properties of the composite. Only the modulus of the 5-ply (0/90) was seen to slightly decrease as the bending ratio decreased.

Abstract:
Abstract Gas injection has become an important means of enhancing oil recovery (EOR) in clastic reservoirs, the Donghe Oilfield, Tarim, has been undergoing gas injection to enhanced oil recovery. During the gas injection, dynamic justification of gas injection was the most severe challenges, which needed to monitor the pressure profile, temperature profile and gas injection profile. Therefore, monitoring gas injection profile has becoming an important part of gas drive reservoirs. Donghe Oilfield was characterized by ultra-deep (>6000m), high temperature (>140°C) and high content of carbon dioxide, conventional manometer and thermometer cannot meet the downhole condition of ultra-deep and high temperature. To continuously monitor gas injection well, permanent fibre-optic surveillance technique featured with outstanding conformance, nice corrosion resistance and long-life span was developed, and a program was developed to use real-time fiber-optic Distributed Temperature Sensing (DTS) and Distributed Acoustic sensing (DAS) to identify the gas injection profile (gas channeling). Monitoring principle and system assembly of the fibre-optic was demonstrated in detail, the DTS utilized Joule - Thompson cooling principle as the gas injected into formation through screen pipe, while the DAS captured the amplitude and frequency of acoustics from the gas flow. DTS and DAS data obtained at the same time by using fiber wireline outside the gas injection string during gas injection. There was a field application in gas injection well of DH1-H3 and gas injection profiles derived from DTS and DAS had the extremely high consistency to radioactive tracer profiles run at about the same time and under similar injection rates and pressure. The success of the fibre-optic surveillance in DH1-H3 exhibited great potential of fiber-optic sensing in gas injection EOR projects, which could provide a new and effective tool in identifying gas channeling.

Full text
Abstract:
Fiber reinforced polymer composites are highly susceptible to environmental conditions despite their favorable properties. Among various environmental factors, moisture absorption is known to have significant adverse effects on such materials. This work investigates the effects of accelerated moisture absorption on the mechanical properties of resin transfer molded glass/epoxy composites. 152.4 mm diameter disk-shaped parts are fabricated using EPON 815C resin and EPICURE 3282 curing agent. Reinforcement is provided by four layers of randomly oriented planar glass fiber preforms with 0.459 kg/m2 surface density, yielding approximately 21.2% fiber volume fraction. Samples cut from the molded disks are immersed into boiling water for accelerated aging. The masses of the specimens are measured at periodic intervals to quantity the amount of water absorbed. Tensile and short beam shear tests are performed at different levels of moisture absorption. Mechanical properties are found to decrease as moisture diffused into the material. Fiber pullouts on the surfaces of tested samples show fiber loosening as the cause of material weakening. To investigate the desorption and characteristics, part of the samples are dried at 65°C after the maximum moisture absorption is reached. Total stiffness recovery is observed after desorption but ultimate tensile strenth only recovered by 27.7%, which is 33.4% lower than the initial value.

Abstract:
Biomass has received wide attention as a substitute for fossil fuel in the generation of energy because of its renewability and carbon neutrality. However, raw biomass combustion is hindered by physical properties such as low energy density and high moisture content. Biomass torrefaction is a mild pyrolysis thermal treatment process carried out at temperature of 200 to 300°C under inert conditions to improve the fuel properties of parent biomass. This yields a higher energy per unit mass product but releases non-condensable and condensable gases which results in energy and mass losses. The condensable gases (volatiles), can result in tar formation on condensing hence, system blockage. Fortunately, the hydrocarbon composition of volatiles also represents a possible auxiliary energy source for torrefaction. The present study investigated energy recovery from volatiles through clean co-combustion with NG for feedstock drying and/or the thermal treatment process of pine wood chips. The research also studied the effect of torrefaction pretreatment temperatures on the amount of energy recovered for various combustion air flow rates. For all test conditions, blue visual flames and low CO and NOx emissions at the combustor exit consistently signified clean and complete premixed combustion. Torrefaction temperature at 283–292 °C had relatively low energy recovered from volatiles, mainly attributed to higher moisture content evolution and low molecular weight of volatiles evolved. At lowest torrefaction pretreatment temperature, smaller amount of volatiles was generated with most energy recovered from the volatiles. Energy conservation evaluation on the torrefaction reactor indicated that about 40% of total energy carried by the exiting volatiles and gases has been recovered by the co-fire of NG and volatiles at the lowest temperature while 20% and 22% of the total energy were recovered at the intermediate and highest torrefaction temperature respectively.
