Abstract:
Corrosion and heat treatment studies are essential to predict the performance and sustainability of the coatings in harsh environments, such as the oil and gas industries. In this study, nickel phosphorus (NiP)–titanium (Ti) nanocomposite coatings (NiP-Ti nanoparticles (TNPs)), containing various concentrations of Ti nanoparticles (TNPs) were deposited on high strength low alloy (HSLA) steel through electroless deposition processing. The concentrations of 0.25, 0.50 and 1.0 g/L TNPs were dispersed in the electroless bath, to obtain NiP-TNPs nanocomposite coatings comprising different Ti contents. Further, the effect of TNPs on the structural, mechanical, corrosion, and heat treatment performance of NiP coatings was thoroughly studied to illustrate the role of TNPs into the NiP matrix. Field emission scanning electron microscope (FESEM) and energy dispersive spectroscopy (EDX) results confirm the successful incorporation of TNPs into the NiP matrix. A substantial improvement in the mechanical response of the NiP matrix was noticed with an increasing amount of TNPs, which reached to its ultimate values (hardness 675 Hv, modulus of elasticity 18.26 GPa, and stiffness 9.02 kN/m) at NiP-0.5TNPs coatings composition. Likewise, the electrochemical impedance spectroscopy measurements confirmed a tremendous increase in the corrosion inhibition efficiency of the NiP coatings with an increasing amount of TNPs, reaching ~96.4% at a composition of NiP-0.5TNPs. In addition, the NiP-TNPs nanocomposite coatings also unveiled better performance after heat treatment than NiP coatings, due to the presence of TNPs into the NiP matrix and the formation of more stable (heat resistant) phases, such as Ni3P, Ni3Ti, NiO, etc., during the subsequent processing.

Abstract:
N-(4-isothiocyano-2-nitrophenyl)-2-aminoethanesulfonate (NIP-taurine), a newly synthesized isothiocyano derivative of N-(4-azido-2-nitrophenyl)-2-aminoethanesulfonate (NAP-taurine), is a potent inhibitor of human erythrocyte chloride exchange. At 0 degrees C, the inhibition is reversible, but at 37 degrees C, NIP-taurine inhibits irreversibly, indicating that it may be a useful label for its binding site. When present at the outside of the cell, NIP-taurine binds with low affinity to a site that seems to be the Cl- transport site (on the basis of its affinity for Cl-) and with much higher affinity to a different site, MN, which has a much lower affinity for Cl-. In this respect, NIP-taurine resembles NAP-taurine, and an analysis of interactions between these two probes is consistent with the idea that they bind to the same two sites. The affinity of NIP-taurine for the high-affinity MN site is enhanced by about fourfold when the transport protein, band 3, is in the conformation with the transport site facing outward (Eo), as compared with the conformation with the transport site facing inward (Ei). External Cl-, but not cytoplasmic Cl-, competes with NIP-taurine for binding to the external, high affinity site. Thus NIP-taurine provides a label for an external site, at which Cl- and perhaps other anions bind, which is separate from both the transport site and the cytoplasmic modifier site at which high Cl- concentrations inhibit Cl- exchange.

Abstract:
External iodide (I-o) inhibits AE1 (band 3)-mediated anion exchange in human red blood cells by binding to a noncompetitive inhibitory site, the external halide modifier site. External N-(4-azido-2-nitrophenyl)-2-aminoethyl sulfonate (NAP-taurine) and N-(4-isothiocyano-2-nitrophenyl)-2-aminoethyl sulfonate (NIP-taurine) also inhibit Cl- exchange noncompetitively. Increasing I-o decreases the inhibitory potency of NIP-taurine in a competitive fashion; this effect is not due to I- binding to the transport site, which has little effect on the NIP-taurine affinity. Bis(sulfosuccinimidyl)-suberate (BSSS) abolishes the noncompetitive inhibitory effect of I-o and greatly reduces the inhibitory effect of NAP-taurine. Together with previous work, these data suggest that external halides, such as I-, Br-, and probably also Cl-, bind to the same noncompetitive inhibitory site as do NAP- and NIP-taurine and that these reagents can be used to label the halide modifier site. Lys-539, a probable reaction site of BSSS, lies within the same segment of AE1 that is labeled by NAP-taurine and thus may be part of the modifier site.

Abstract:
Nickel-based and cobalt-based metal alloys are frequently used in dentistry. The introduction of various elements in the alloy changes its characteristics, and a thorough study of each alloy should be completed to determine its appropriate corrosion resistance and biocompatibility in contact with physiological fluids. There are scarce investigations on these widely used dental alloys in Ringer solution, and findings in this research bring new experimental data and information. The present study evaluated and compared the corrosion behavior of six NiCr- and two CoCr-based dental materials in Ringer solution, using the following techniques: potentiostatic polarization curves (chronoamperometry), microstructural analysis, and EIS (electrochemical impedance spectroscopy). The results obtained in this investigation showed that in the NiCr-based specimens Ni4, Ni5, and Ni6 the stability of the passive layer was destroyed after polarization and a development and growth of stable pits was found in the microstructural analysis after electrochemical treatment. In terms of susceptibility to corrosion, two different groups of specimens were derived from this investigation. A first group which included the two CoCr (Co1 and Co2) and three of the six NiCr alloys studied (Ni1, Ni2, and Ni3). A second group with the other NiCr alloys investigated Ni4, Ni5, and Ni6.

Abstract:
NiP (P > 10 wt.%) coatings are amorphous coatings whose structure can be transformed by heat treatment into a crystalline structure and hardened by precipitation of Ni3P. In this study, NiP coatings and composite ones with SiC nanoparticles were produced by electrodeposition, and their structural transformation by heat treatment was studied using differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The microhardness and the scratch and corrosion resistance of the coatings were evaluated and compared before and after different heat treatments. The results showed that in as-plated condition, the addition of SiC particles in the coatings did not modify the microstructure, microhardness, or electrochemical behavior. However, the SiC particles’ role was disclosed in combination with heat treatment. Composite coatings that were heat treated at 300 °C had higher microhardness and scratch resistance than the pure NiP one. In addition, composite coatings maintained their scratch resistance up to 400 °C, while in the case of the NiP ones, there was a reduction in scratch resistance by heating at 400 °C. It was also concluded that heating temperature has the main role in hardness and corrosion resistance of NiP and composite coatings, rather than heating time. The optimum heat-treatment protocol was found to be heating at 360 °C for 2 h, which resulted in a maximum microhardness of about 1500 HV0.02 for NiP and its composite coating without sacrificing the corrosion resistance.

Abstract:
Abstract Policy makers in regions such as Europe are increasingly concerned about the trustworthiness and sovereignty of the foundations of their digital economy, because it often depends on systems operated or manufactured elsewhere. To help curb this problem, we propose the novel notion of a responsible Internet, which provides higher degrees of trust and sovereignty for critical service providers (e.g., power grids) and all kinds of other users by improving the transparency, accountability, and controllability of the Internet at the network-level. A responsible Internet accomplishes this through two new distributed and decentralized systems. The first is the Network Inspection Plane (NIP), which enables users to request measurement-based descriptions of the chains of network operators (e.g., ISPs and DNS and cloud providers) that handle their data flows or could potentially handle them, including the relationships between them and the properties of these operators. The second is the Network Control Plane (NCP), which allows users to specify how they expect the Internet infrastructure to handle their data (e.g., in terms of the security attributes that they expect chains of network operators to have) based on the insights they gained from the NIP. We discuss research directions and starting points to realize a responsible Internet by combining three currently largely disjoint research areas: large-scale measurements (for the NIP), open source-based programmable networks (for the NCP), and policy making (POL) based on the NIP and driving the NCP. We believe that a responsible Internet is the next stage in the evolution of the Internet and that the concept is useful for clean slate Internet systems as well.

Abstract:
Nickel phosphide (Ni2P) is a promising material for the electrocatalytic generation of hydrogen from water. Here, we present a chemical picture of the fundamental mechanism of Volmer–Tafel steps in hydrogen evolution reaction (HER) activity under alkaline conditions at the (0001) and (10 1 ¯ 0) surfaces of Ni2P using dispersion-corrected density functional theory calculations. Two terminations of each surface (Ni3P2- and Ni3P-terminated (0001); and Ni2P- and NiP-terminated (10 1 ¯ 0)), which have been shown to coexist in Ni2P samples depending on the experimental conditions, were studied. Water adsorption on the different terminations of the Ni2P (0001) and (10 1 ¯ 0) surfaces is shown to be exothermic (binding energy in the range of 0.33−0.68 eV) and characterized by negligible charge transfer to/from the catalyst surface (0.01−0.04 e−). High activation energy barriers (0.86−1.53 eV) were predicted for the dissociation of water on each termination of the Ni2P (0001) and (10 1 ¯ 0) surfaces, indicating sluggish kinetics for the initial Volmer step in the hydrogen evolution reaction over a Ni2P catalyst. Based on the predicted Gibbs free energy of hydrogen adsorption (ΔGH*) at different surface sites, we found that the presence of Ni3-hollow sites on the (0001) surface and bridge Ni-Ni sites on the (10 1 ¯ 0) surface bind the H atom too strongly. To achieve facile kinetics for both the Volmer and Heyrovsky–Tafel steps, modification of the surface structure and tuning of the electronic properties through transition metal doping is recommended as an important strategy.

Abstract:
The present work deals with the formation of NiP/NiB duplex coatings by electroless plating and evaluation of their hardness and wear resistance. The duplex coatings were prepared with Ni-P as the inner layer. To analyze the structure of the coatings, XRD analysis was carried out. According to the results, NiP and NiB coatings are amorphous in their as-plated condition and after applying heat-treatment at 450 °C for 1 h, both NiP and NiB coatings crystallize and produce nickel, nickel phosphide and nickel borides in the coatings. To determine the surface morphology and cross-section characteristics of the coatings, SEM observations were carried out and concluded that duplex coatings are uniform and good coherent exists between the duplex layers and the coatings are also connected closely to the substrate. The hardness of electroless nickel duplex coatings increased with applying heat treatment and reached maximum value at coatings annealed at 400 °C. To analyze the tribological properties, pin-on-disc tests were carried out. The wear track patterns on the coatings and on Al2O3balls were then examined by optical microscopy and EDS. The friction coefficient and wear rate of the coatings were lower than the substrate steel. Friction coefficient decreased from 0.43 to 0.36 and wear resistance decreased from 11.3 to 6.4 by applying heat treatment at 450 °C for 1 h to duplex coatings.

Le domaine de cette thèse est la théorie des modèles, une branche de la logique mathématique.Ce travail porte sur l'étude d'une classe de théories, appelés théories NIP, qui inclut en particulier des corps ordonnés et corps valués. On y étudie plusieurs aspects. Tout d'abord, on définit une classe particulière de mesures sur ces structures, appelées "mesures génériquement stables". On montre qu'elles ont des propriétés analogues aux types dans une théorie stable, puis on donne des constructions pour en produire. On étudie aussi une forme faible de définissabilité des types. Enfin, on définit une notion de théories NIP "purement instable" et on montre comment on peut, dans le cas général, détecter des parties stables de types.

Abstract:
Paper in a calender nip is subjected to a pressure pulse which reduces its thickness and roughness, thus improving the product quality. Strain recovery after the nip is time-dependent, and some permanent strain remains. The material behaviour is viscoelastic; recovery depends on the pulse magnitude and duration, and does not occur immediately on exiting the nip. An improved description of the viscoelastic response to a calender pulse would allow design of adaptive control systems using feedforward techniques.
Measurements of paper thickness in the nip, immediately after the nip and 24 hours after calendering were made with newsprint sheets running through an experimental calender operating at industrial conditions. The calculated strains were first related to the operating conditions using empirical curve-fitting methods, then using linear viscoelastic models. Empirical results describe the data well, and can be used to design improved control systems. Linear viscoelastic modeling was less successful since the material behaviour is not linear. Photomicrographs of sheet cross-sections were taken, and the observed non-linearities were discussed qualitatively in terms of paper and fibre properties.

Abstract:
L’obtenció de recobriments compòsits mitjançant la incorporació de partícules en una matriu determinada ha conduit a una nova generació de materials amb unes propietats particulars, depenent tant de la naturalesa de la matriu com de les partícules emprades. En els darrers anys ha sorgit un gran interes en l’obtenció de compòsits amb partícules nanomètriques, ja que s’ha constatat que la reducció de la mida de la partícula pot modificar substancialment les propietats del dipòsit i permet la reducció de la mida del suport, tot obrint un nou ventall d’aplicacions. L’aplicació de la tecnologia electroquímica a l’obtenció d’aquests recobriments té dues etapes de difícil control: l’obtenció de les dispersions de les partícules i el propi procés de codeposició. La disminució de la mida de les partícules exalta els problemes d’agregació a les dispersions, donant lloc a la formació d’agregats de mida sub-micromètrica. El sistema NiP/X, format per una matriu de níquel i partícules ceràmiques, es escollit pel seu interès tecnològic, cercant analitzar l’efecte de la mida de les partícules sobre les propietats dels compòsits obtinguts per incorporació de nanopartícules de SiC i Si3N4 dins una matriu de níquel, mantenint en tot moment la referència al comportament de les micropartícules i emprant la via electroless. Segons això, la tesi s'estructura en tres parts: 1. Caracterització de les nanopartícules de SiC i Si3N4 i de les seves dispersions: la distribució de mida de partícula (PSD) i el potencial zeta (ζ) són dos paràmetres importants per caracteritzar el comportament de les partícules suspeses en un medi i relacionats amb les caracteristiques de la seva superfície. Es detalla el treball fet sobre la caracterització de l'estructura i composició superficial de les nanopartícules, l'estudi del seu comportament en suspensió i de l'efecte dels diferents components d'un bany electroquimic sobre aquestes propietats, amb especial èmfasi en les determinacions efectuades sobre electròlits concentrats i a temperatura relativament elevada i amb la presencia de fluorosurfactants fins ara no estudiats. 2. Obtenció de compòsits per electroless i la seva caracterització: es tracta el procés de deposició i la caracterització dels dipòsits obtinguts. S'estudia la morfologia, composició i estructura així com les propietats de resistència a la corrosió, duresa i resistència al desgast dels recobriments. Buscant l'aplicació directa dels compòsits obtinguts, es treballa amb un bany comercial que proporciona recobriments amb propietats contrastades. D'altra banda, per a l'estudi de l'efecte dels fluorosurfactants s'utilitza un bany de composició més simple. 3. Anàlisi comparativa de la duresa, la resistència al desgast i la fricció: el principal objectiu de la incorporació de partícules ceràmiques a un dipòsit de matriu metàl.lica és l’augment de la seva duresa i resistència al desgast. Existeixen molts mètodes d'assaig d'aquest tipus de propietats i se'n pot obtenir informació molt diversa, encara que els més habituals estan dimensionats per l’avaluació de materials màssics. En aquest capítol es discuteix la seva aplicació a l'avaluació de recobriments compòsits, fent una anàlisi comparativa global de tota la tecnologia avaluada. Quan es va comencar aquest treball, es va considerar interessant dur a terme un estudi final comparatiu dels sistemes NiP/X obtinguts per electrodeposició. Pel seu interès tecnològic es va escollir un bany de sulfamat de nóquel com a electròlit de treball. Però la manca de dades de referéncia sobre el comportament electroquímic d'aquest bany (no es troben referencies bibliogràfiques sobre l'estudi de l'electrodeposició de Ni a partir d'aquest tipus d'electròlits ni de l'obtenció de NiP i els seus composits), ha reduït aquesta part a l’estudi inicial del comportament del bany, l’anàlisi del procés d’electrodeposició i la caracterització dels dipòsits obtinguts.
NiP electroless is widely used because of its corrosion and wear resistances and its uniform coating thickness. Moreover, it is known that the incorporation of particles onto this NiP matrix provides enhanced surface properties, depending on the particle nature. Hard particle-containing deposits have been developed when the main requirement for the composite coating is wear resistance. Among these coatings, the combination NiPSiC has proved to be the most cost-effective and best-performing combination. The final properties of these coatings depend on the phosphorous content of the NiP matrix, which determines the structure of the coatings, and on the characteristics of the embedded particles such as type, shape and size. Most studies concerning NiP-hard particle systems are performed using micron-sized particles and some commercial processes exist to obtain such composites. However, the development of nanotechnologies has raised the interest on the metal matrix nano-composite coatings because of their unique mechanical, magnetic and optical properties. With the commercial NiP electrolyte and the ceramic particles used in this study, two different patterns have been observed when trying to obtain composite coatings. In the range between 0.6 and 2 ,m, no significant differences have been observed between the SiC and Si3N4 particles. In both cases, the amount of embedded particles increases with particle size and their incorporation modifies neither the phosphorous content nor the deposition rate of the process. The composite coatings show uniformly distributed particles and the hardness and wear resistance are improved, particularly with the SiC particles and after annealing. However, when nano-sized particles are used, the behaviour of the two ceramics diverges: SiC is incorporated to a relatively high amount, while Si3N4 is not. At this size level, the nature of the particle seems to be the most important factor in determining its incorporation into the metallic matrix. The presence of SiC nano-particles reduces the rate and modifies the coating morphology, altering NiP growth to a much greater extent than do micro-sized ones. Nano-composites show excellent properties, even better than those of micro composites, as lower amounts of embedded particles are needed to obtain the same response.

Full text
Abstract:
The hydrodynamics and mechanical behaviour of a soft nip between a rubber-covered roller and a rigid roller has been studied. The thesis reports the developments and the results of a combined theoretical and experimental investigation into the nip flow of Newtonian and non-Newtonian fluids operating under various roller mechanical engagements, speeds and other design parameters. The theoretical model has been developed based on a Finite Element method (FEM) to solve for the equation set of generalised pressure and plane strain elasticity equations under a pure rolling contact. Several numerical studies for Newtonian fluid were then carried out to verify the basis of the present model. As far as the author is aware, no published work has hitherto studied the effect of non-Newtonian fluid flow in a soft contact. The comparison between the present Newtonian and non-Newtonian models suggests considerable variation in the film thickness caused by the shear thinning action in the non-Newtonian fluid. Concurrently, an experimental programme was conducted using a real printing unit which was converted to an experimental test rig. The parameters that were measured were pressure, film thickness, speed and temperature. The results provide detailed behaviour of the rollers investigated, and these were used to verify the predicted nip behaviour. The measured results showed that very small speed differentials occur in the nip, and the hysteresis of the rubber was the major source of the heat build-up in the roller. Also, comparison of predicted and measured pressure showed close agreement for low levels of roller engagement and at low speeds. Systematic numerical case studies were carried out to ascertain the parameters which most affect the nip behaviour. Supported with the comparisons of published data where possible, the results showed that rubber modulus, roller engagement, viscosity and speed were the most influential parameters.

Dans ce présent travail des revêtements composites à matrice métallique Ni-P chargés de particules de SiC (tailles moyennes 600 et 30 nm) sont électrodéposés à partir d'une solution de sels de nickel et d'un précurseur phosphoreux H3PO3, dans laquelle les particules sont mises en suspension. Par des mesures de viscosité, de vitesse de sédimentation nous montrons que la taille des particules est une caractéristique importante qui joue sur la stabilité des suspensions. Nous montrons que l'ajout d'additifs organiques dans le but de modifier le comportement des suspensions, peut avoir suivant la taille des particules, un effet sur leur taux d'incorporation dans le dépôt. Nous observons qu'au-delà d'une certaine concentration en particules dans la suspension, le taux d'incorporation évalué en fraction volumique atteint un palier, caractéristique de la saturation de la surface cathodique alors que pour les fortes concentration de la suspension le procédé devient sélectif et les particules de plus faibles tailles sont incorporées préférentiellement. Des analyses thermiques, des mesures mécaniques et des analyses életrochimiques par voltametrie cyclique et d´impedance électrochimique, mettent en évidence l'effet de la quantité et de la taille des particules incorporées sur le comportement thermique, la microdureté et la résistance à corrosion des revêtements composites Ni-P / SiC
In this work electrodeposited Ni-P/SiC composites coatings had been electrodeposited from a nickel salts solution containing H3PO3 and SiC particles in suspension (600nm and 30nm). Through measures of viscosity and sedimentation speed it was evidenced that the size of particles is a very important characteristic and it influences in the suspension stability. We had shown that organic additives modifies the characteristic of suspensions. Depending on size particles the organic additives can change the number of incorporated particles. It was observed that depending on the particles concentration in suspension, the number of incorporated particles in deposits can be changed. The incorporation rate evaluated as a function of the fraction in volume reaches a plateau, but continues to increase if it´s evaluated as a function of the number of particles. For the suspensions with raised particles concentration, the incorporation process becomes selective, and the particles with small size are preferentially incorporated. Microhardness measurements, thermal analysis and electrochemical analysis, (cyclic voltammetry and electrochemical impedance spectroscopy) were used to evaluate the influence of the amount and distribution of SiC incorporated particles on the microhardness, corrosion and thermal behaviour of Ni-P/SiC composite coating

Abstract:
Nous avons élaboré des poudres NiP de teneur en phosphore de 8% at P à 17% at P en maintenant constant tous les paramètres physico-chimiques excepté la concentration en phosphore dans les bains. Les poudres obtenues par cette nouvelle technique sont identifiées par diffraction de rayon X comme étant amorphe. Nous avons cherché à caractériser le comportement des différentes poudres pendant les étapes de compactage uniaxial. On a pu retenir l'existence de mise en forme (300 à 600 MPa) ou les particules de poudres subissent un réarrangement, la deuxième étape pour des pressions supérieurs à 600 MPa est attribuée à la déformation plastique des particules de poudres. La stéréologie a permis de caractériser la structure interne des agglomérés de poudre et de décrire leur évolution ainsi que celles des propriétés physiques et mécaniques depuis l'état du comprime jusqu'au stade ultime du frittage. Au cours de la montée en température, on a pu atteindre 95% de la densité théorique pour toutes les poudres compactées à haute pression. Les mesures de la résistivité électrique nous ont permis de mettre en évidence une transition de phase amorphe-cristal vers 300 °C pour tous les comprimés, une deuxième transition de phase apparait vers 500 °C pour les comprimés à 12% at P et 17% at P ou la cristallisation se fait en deux étapes, précipitation de Ni puis Ni3P et croissance cristalline au sein du matériau. La microdureté Vickers ainsi que le module d'Young évoluent de manière cohérente avec la montée en température
We have elaborated five powders of NiP with 8% at P et 17% at P. The chemical and physical parameters are kept constant except concentration of phosphorus into bath. The powders obtained with this new technique are identified amorphous with X rays. We have tried to caracterize behaviour of different powder during uniaxial compacting stage. There are two stages during compaction, the first one for low pressure compacting (300 à 600 MPa) when the aprticles of powder undergo arrangement, second stage for high pressure was attributed to the plastic deformation of powder particles. Stereology made it possible to caracterize internal structure, to describe behaviour, physics and mechanics properties of conglomerate of powder compacted till ultimate of sinttering. During temperature rising, we have attained 95% of theorical density for all compacted at high pressure. We could bring to the fore one transition of amorphous-crystal phase at 300°C with measurements of electrical resistivity for all compacted, second transition became visible at 500°C for powder at 12% at P and 17% at P who cristalization it made of two stages, precipitation of Ni then Ni3P and growth within material. Vickers Microhardness and Young module evolved well with rising temperature

Abstract:
From acidic NiP electroless bath, the co-deposition of TiNi nanoparticles in the NiP matrix to form novel NiP-TiNi nanocomposite coatings (NCCs) on top of API X100 carbon steel using several concentrations of TiNi nanoparticles (0.2, 0.4 and 0.8 g L-1 in the bath) is successfully achieved. The influence of the TiNi nanoparticles on the composition, deposition rate, thickness, and morphology of the NiP coating are investigated before and after annealing at 400 oC. The addition of TiNi nanoparticles into the NiP matrix led to the transform of the amorphous structure of the as-plated NiP into a semi-crystalline one. The microhardness of the composite coating significantly enhances with increasing TiNi concentration up to 0.4 g L-1 and further improvement takes place after heat treatment. The electrochemical impedance spectroscopy (EIS) and the colony counting method are carried out to assess the corrosion protection and antibacterial properties, respectively, of the as-deposited and the annealed coatings. The results demonstrate that there is an optimum concentration for the addition of TiNi (0.4 g L-1), which offers the composite coating with the highest corrosion protection that reaches to about 98 %. Below and beyond this concentration as well as after heat treatment, the improvement in the corrosion protection of the composite coatings slightly decreases. Besides, the NiP–TiNi NCCs have effective antibacterial properties as it decreased the cell viability of Escherichia coli from 100 to 19%.
