Considered in this paper is a semi-infinite cellular ceramic solid containing an edge crack. The solid is subjected to a sudden cooling on its surface. The temperature field and associated thermal stress field for the uncracked solid are calculated. The stress for uncracked medium is used as the crack surface stress with opposite sign to formulate the mixed boundary value problem. The stress intensity factors as the function of crack length, time and relative density are calculated. It is found that the presence of porosity in the ceramic is generally beneficial to increasing the thermal shock strength of the ceramics if the failure is dominated by a pre-existing crack. The paper may be helpful for the design and manufacturing of advanced thermal shock resistive cellular ceramics.

AbstractCellular ceramics are a class of high-porosity materials that are used or are being considered for a wide range of technological applications. A critical aspect of this development is the materials science approach required to understand the relationships between the properties of these materials and their structure. Of particular interest are the parameters that control mechanical reliability, as ceramic materials are usually brittle. In addition, it is critical to understand the way in which processing methods can influence the cellular structure. This article emphasizes one particular group of cellular ceramics known as ceramic foams. Understanding these materials involves various interdisciplinary scientific challenges in characterizing structure, developing micromechanical models, experimentally measuring properties, developing new processing approaches, and optimizing performance.

Cellular ceramics have been produced by several methods, giving a wide range of macrostructures and properties. This work describes a novel route to produce cellular ceramics based on the gel casting of emulsions consisting in an aqueous ceramic suspension containing water-soluble organic monomers and an emulsified insoluble liquid phase. The effects of solids loading and kerosene fraction on the rheological properties of emulsions were characterized. Samples with different kerosene additions (20, 30, 40 and 50 %vol.) were produced and their green and sintered densities were measured. The results have shown a good correlation between the volumetric fraction of kerosene into the emulsion and the porosity of samples. Diametrical compression was used to evaluate the strength of sintered samples, which varied with the porosity between 18 and 37 MPa. The cellular structure was analyzed by SEM and revealed isolated pores for samples with low porosity, which changed to an interconnected network of pores as the porosity increased.

Several kinds of wastes have been converted into glasses, successively powdered and sintered with simultaneous crystallisation. The employed “sinter-crystallisation” process was useful to obtain glass-ceramics with particular crystal phases (sometimes un-accessible from traditional nucleation/crystal growth treatments, like feldspar crystals). Conventional pressing of fine glass powders led to monoliths, after sintering, with remarkable mechanical properties (for example bending strength exceeding 100 MPa), useful for tile applications; replication processes, by employing sacrificial polymeric materials, after the same thermal treatment employed for the monoliths, led to open-celled glass-ceramic foams, useful for filtering applications. The enhanced specific surface due to porosity was found to have a positive effect on crystallisation.

The research work presented in this thesis concerns the development of silicon nitride based ceramics with a cellular structure and containing designed interconnected porosity (> 80 vol%) and cell size distribution (10 up to 800 μm) by direct foaming processing routes. Concentrated emulsions (O/W oil-in-water) stabilized by surfactants and gelcasting using environmentally friendly biopolymers as gelling agents, were developed as intermediates in the production of highly porous inorganic materials. Differently from conventional direct foaming methods the evaporation (and expansion) of the alkane droplets affords the foaming during drying of emulsions. Sintering is a critical step in the case of silicon nitride, since high temperatures and increased dwelling time are necessary for sufficient densification to occur, due to a low diffusion in the solid state. In order to overcome this difficulty, we report in this thesis two different strategies by liquid phase sintering with sintering additives: 1) Conventional sintering at 1600 °C and 1700 °C, using N2 flow in order to suppress the dissociation reactions and permit sintering with little weight loss. 2) Sintering by intense thermal radiation, inside a modified SPS set-up, shows to be effective in promote densification of the foam struts and develop of SiC nanowires (increase the fracture toughness of Si3N4 foams) on the cell walls and struts at short times and lower sintering temperatures. Further, the influence of the sintering additives, Y2O3 and MgO, and the effect of the sintering temperature on the formation of rod-like β–Si3N4 grains were also investigated. Highly porous Si3N4 ceramics are promising candidate for various engineering applications such as: gas filtering application (high temperature and harsh environment), heat insulators, catalyst carriers, bioreactors, medical implants, since recent results confirmed the non-cytotoxicity and biocompatibility, owing to remarkable properties as high strength, high stiffness, good toughness, high temperature resistance, high corrosion resistance, good wear resistance and high permeability. During the present research work, the characterization of highly interconnected Si3N4 foams in terms of microstructure (cell size distribution and porosity), mechanical properties and permeability was performed. High compressive strengths (up to 33 MPa) were reported with the increasing of sintering temperature up to 1700 °C (conventional sintering), owing to the development of elongated β–grains, as well a strong packing of particles on cell walls and struts. Permeability evaluation shows that Si3N4 foams are in the range of gelcasting foams (on permeability map) and are suitable for filtering application. The successful combination of colloidal processing, foaming and fast consolidation of foams, and also pressureless sintering at relatively low temperatures applied to produce cellular ceramics based on Si3N4 was also extended to other advanced materials e.g. max-phases belonging to Ti-Al-C system.
Materiali ceramici a base di Si3N4 altamente porosi sono potenziali candidati per varie applicazioni di ingegneria: filtraggio di gas ad alta temperature ed in condizioni critiche, isoltaori termici, trasporto di catalizzatori, bioreattori e impianti biomedici (recenti risultati di letteratura hanno confermato la non citotossicità e la biocompatibilità del Si3N4). L’attività di ricerca della presente tesi riguarda lo sviluppo di materiali ceramici a base di nitruro di silicio caratterizzati da una struttura cellulare, contenenti porosità interconnessa (> 80 vol%) e celle con una distribuzione dimensionale che varia dai 10 μm fino agli 800 μm. La tecnica utilizzata per la produzione dei materiali ceramici cellulari consiste nella schiumatura diretta; sono state sviluppate emulsioni concentrate (O/W olio-in-acqua) stabilizzate da tensioattivi e gelcasting di biopolimeri ecocompatibili, come step intermedi nella produzione di materiali inorganici altamente porosi. Diversamente dai tradizionali metodi di schiumatura diretta, la schiumatura è fornita dall’ evaporazione (ed espansione) delle gocce di alcani durante l'essiccazione delle emulsioni. Mentre nel caso di gelcasting, la capacità dei tensioattivi schiumogeni combinata con la gelificazione termica fornisce la schiumattura. Nel caso della produzione di componenti a base di nitruro di silicio la sinterizzazione rappresenta un punto critico, poiché sono necessarie temperature elevate e prolungato tempo di mantenimento alla T di sinterizzazione al fine di garantire sufficiente densificazione a causa delle basse velocità di diffusione allo stato solido. Al fine di superare queste difficoltà, nella presente tesi sono state sviluppate due strategie: 1) Sinterizzazione convenzionale a 1600 °C e 1700 °C in flusso di N2, al fine di inibire le reazioni di dissociazione e sinterizzare con basse perdite di peso. 2) Sinterizzazione con intensa radiazione termica, attraverso la tecnica dello Spark Plasma Sintering (SPS), la quale si è dimostrata efficace al fine di densificare gli struts della schiuma e sviluppare nanofili di SiC sulle pareti di cella e sugli struts, a temperature più basse e per tempi più brevi rispetto alla sinterizzazione convenzionale. Nanofili di SiC contribuiscono ad aumentare la resistenza alla frattura delle schiume. Inoltre, l’influenza di addittivi di sinterizzazione, Y2O3 e MgO, sulla temperatura di sinterizzazione e sulla formazione di β–Si3N4 grains, sono stati investigati. Le strutture cellulari a base di Si3N4 prodotte con le tecniche sopra descritte sono state caratterizzate in termini di microstruttura (distribuzione della dimensione di celle e porosità), proprietà meccaniche (test di compressione) e permeabilità ai gas. Porosità totale che varia dai ~74 fino agli 89 vol%, e le dimensioni delle celle variano in un ampio range ~20 fino agli 850 μm, in funzione della velocità di emulsione, tipici di biopolimeri. E’ stato trovato che le schiume sinterizzate a 1700 °C (sinterizzazione convenzionale) sono caratterizzate da elevati valori di resistenza a compressione up to 33MPa per effetto dello sviluppo di grani allungati di fase β–Si3N4 e per effetto della notevole densificazione delle particelle in corrispondenza delle pareti di cella e degli struts. Le misure di permeabilità hanno dato valori di costanti di permeabilità nel range delle schiume ottenute con la tecnica del gelcasting e sono pertanto utili per applicazioni di filtraggio. La combinazione di processi colloidali, schiumatura, rapida consolidazione delle schiume e sinterizzazione in assenza di pressione a temperature moderate applicate ai ceramici porosi a base di Si3N4, sono state applicate anche ad altri sistemi come ad esempio al sistema Ti-Al-C (Max-Phases).

Ceramic additive manufacturing is gaining popularity with methods like selective laser sintering (SLS), binder jetting, direct ink writing and stereolithography, despite their disadvantages. Laser sintering and binder jetting are too expensive, while direct ink writing lacks resolution and stereolithography lacks scalability. The project aims to combine one of the most versatile, affordable, and readily available 3D printing methods: fused filament fabrication (FFF) with polymer derived ceramics to produce cellular ceramics to overcome the disadvantages posed by the other methods. The process uses a two-step approach. The first step is to 3D print the part using a polymer FFF 3D printer with a thermoplastic polyurethane filament and the second step is to impregnate the part in a polysilazane preceramic polymer and then pyrolyze it in an inert environment up to 1200C. The resulting product is a high-resolution cellular ceramic of the composition SiOC(N). This type of cellular ceramic can find an application in several fields such as scaffolds for bone tissue regeneration, liquid metal filtering, chemical and gas filtering, catalytic converters and electric applications. The process can provide an affordable alternative to the products used in these fields currently.

This research project focuses on the production of ceramics via Additive Manufacturing (AM) techniques, with particular focus on extrusion-based technologies. The main advantage of AM is the ability to produce cellular structures with high complexity and controlled porosity, allowing to manufacture light but efficient stretch-dominated structures. The inspiration comes from nature: bone architectures are a great example, consisting of thin, solid skins attached to highly porous, cellular cores. Very few commercially available AM systems are suited for ceramic materials, and most of them use ceramic powders as feedstock. Residual pores and cracks are very hard to avoid and result in low strength, poor reliability and loss of unique material properties such as glass optical transparency. AM technologies employing polymers are at a much more advanced stage of development. The goal has been to exploit such advances and to provide alternatives to the ceramic powder-binder approaches. Three different material families were explored: preceramic polymers, geopolymers, and glass. The same preceramic polymer, a commercial polysilsesquioxane, was employed as a non sacrificial, reactive binder to develop inks for stereolithography (SL) and direct ink writing (DIW). The first technology allowed for production of dense, crack-free SiOC micro-components with strut size down to ~200 μm and optimal surface quality. No shape limitations were experienced, but porous structures or small dense parts are the best options in order to avoid residual pores and cracks. The second approach was employed for the fabrication of complex biosilicate scaffolds for tissue engineering with a rod diameter of 350 µm and unsupported struts. The preceramic polymer had the double role of source of silica and rheology modifier. Ceramic matrix composites (CMCs) were also fabricated; the preceramic polymer developed the ceramic matrix (SiOC) upon pyrolysis in inert atmosphere, whereas reinforcement was given by chopped carbon fibers. Geopolymer components with controlled porosity were designed and produced first by negative replica of PLA sacrificial templates and then by DIW. Highly porous ceramic components with features of ~800 μm and unsupported parts with very limited sagging were produced with the latter approach. A novel extrusion-based AM approach was finally developed for the production of objects starting from molten glass. The system processed glass from the molten state to annealed components of complex, digitally designed forms. Objects possessing draft angles and tight radii were fabricated. Within the design space it was possible to print with high precision and accuracy; parts showed a strong adhesion between layers, and high transparency through the layers.
Questo progetto di ricerca riguarda la produzione di ceramici tramite tecniche di manifattura additiva (AM), con particolare focus su tecnologie estrusive. Il principale vantaggio dell’AM è la possibilità di produrre strutture cellulari ad elevata complessità e porosità controllata, consentendo di produrre reticoli stretch-dominated leggeri ma efficienti. L’ispirazione è offerta dalla natura: le strutture ossee sono un ottimo esempio, in quanto si compongono di un involucro esterno, denso e sottile, e di un cuore a struttura cellulare altamente porosa. I sistemi di AM disponibili in commercio per la produzione di componenti ceramici sono molto pochi, e la maggior parte di essi utilizza polveri ceramiche. È molto difficile evitare porosità residua e cricche, e di conseguenza si ottengono oggetti dalla resistenza limitata e privi delle peculiarità di alcuni materiali, come ad esempio la trasparenza del vetro. Le tecnologie di AM che utilizzano polimeri sono ad uno stadio di sviluppo molto più avanzato. L’obiettivo è di sfruttare tale vantaggio e di fornire alternative agli approcci polvere-legante. Sono stati esplorati tre diversi materiali: polimeri preceramici, geopolimeri, e vetro. Un unico polimero preceramico, un polisilsesquiossano commerciale, è stato utilizzato come legante reattivo, non sacrificale per lo sviluppo di inchiostri per stereolitografia (SL) e direct ink writing (DIW). La prima tecnologia ha consentito di produrre micro-componenti in SiOC densi e privi di cricche, con una dimensione dei pilastri fino a ~200 μm e ottima qualità superficiale. Non ci sono state limitazioni di forma, anche se strutture porose o oggetti densi di piccole dimensioni sono da preferire per evitare porosità residua e cricche. Il secondo approccio ha portato alla fabbricazione di scaffold bioceramici per ingegneria tissutale con filamenti di diametro 350 µm e parti non supportate. Il polimero preceramico ha il doppio ruolo di fonte di silice e di modificatore reologico. Sono stati prodotti anche compositi a matrice ceramica (CMCs); il polimero preceramico sviluppa la matrice (SiOC) tramite pirolisi in atmosfera inerte, mentre il rinforzo è dato da fibre di carbonio macinate. Componenti in geopolimero a porosità controllata sono stati progettati e prodotti prima tramite replica negativa di template sacrificali in PLA, e poi via DIW. Il secondo approccio ha portato alla produzione di reticoli ceramici con filamenti di ~800 μm e parti non supportate con deflessione molto limitata. È stato sviluppato infine un innovativo processo estrusivo a partire da vetro fuso. Un unico sistema è in grado di lavorare il vetro dallo stato fuso fino alla ricottura di componenti complessi progettati digitalmente. Sono stati realizzati oggetti comprendenti sporgenze di diversa entità e piccoli raggi di curvatura. All’interno dello spazio di progettazione è stato possibile stampare con elevata precisione e accuratezza; le parti stampate mostrano una forte adesione tra gli strati e un’elevata trasparenza attraverso di essi.

This thesis presents mathematical modeling and control techniques that can be used to predict and specify performance of biologically inspired actuation systems called cellular actuators. Cellular actuators are modular units designed to be connected in bundles in manner similar to human muscle fibers. They are characterized by inherent compliance and large numbers of on-off discrete control inputs. In this thesis, mathematical tools are developed that connect the performance to the physical manifestation of the device. A camera positioner inspired by the human eye is designed to demonstrate how these tools can be used to create an actuator with a useful force-displacement characteristic. Finally, control architectures are presented that use discrete switching inputs to produce smooth motion of these systems despite an innate tendency toward oscillation. These are demonstrated in simulation and experiment.

Abstract A one-dimensional model accounting for the interaction of convection, conduction, radiation and chemical reaction in a porous radiant burner/healer has been developed to predict the thermal performance of the natural gas burner. The porous radiant burner consists of two layers of cellular (reticulated) ceramics of different porosity and mechanical structure. The chemical heat release was simulated using a uniform heat source model to avoid the uncertainties associated with chemical kinetics parameters in a reduced chemical mechanism under strongly non-adiabatic conditions. Radiative transfer in the porous medium is modeled using the two-flux approximation. The model predictions reveal quantitatively conjugate heat transfer between convection, conduction, radiation and chemical heat release. A study of the effects of various parameters on the thermal performance of the porous radiant burner and comparison of predictions with experimental data are reported. The results obtained show that the flame thickness in this type of burners is much broader than that of conventional adiabatic combustion due to the strong conduction and radiation feedback from the high temperature (flame) region to the preheat region. The peak gas temperature is lower than that for conventional adiabatic premixed combustion conditions since part of the chemical heat release is convected to the solid.

The overall objective of the current proposal is to develop procedures to improve the pregnancy rate achieved following transfer of fresh or cryopreserved embryos produced in the laboratory into heat-stress recipients. The overall hypothesis is that pregnancy rate in heat-stressed lactating cows can be improved by use of embryo transfer and that additional gains in pregnancy rate can be achieved through development of procedures to cryopreserve embryos, select embryos most likely to establish and maintain pregnancy after transfer, and to enhance embryo competence for post-transfer survival through manipulation of culture conditions. The original specific objectives were to 1) optimize procedures for cryopreservation (Israel/US), 2) develop procedures for identifying embryos with the greatest potential for development and survival using the remote monitoring system called EmbryoGuard (Israel), 3) perform field trials to test the efficacy of cryopreservation and the EmbryoGuard selection system for improving pregnancy rates in heat-stressed, lactating cows (US/Israel), 4) test whether selection of fresh or frozen-thawed blastocysts based on measurement of group II caspase activity is an effective means of increasing survival after cryopreservation and post-transfer pregnancy rate (US), and 5) identify genes in blastocysts induced by insulin-like growth factor-1 (IGF-1) (US). In addition to these objectives, additional work was carried out to determine additional cellular determinants of embryonic resistance to heat shock. There were several major achievements. Results of one experiment indicated that survival of embryos to freezing could be improved by treating embryos with cytochalasin B to disrupt the cytoskeleton. An additional improvement in the efficacy of embryo transfer for achieving pregnancy in heat-stressed cows follows from the finding that IGF-1 can improve post-transfer survival of in vitro produced embryos in the summer but not winter. Expression of several genes in the blastocyst was regulated by IGF-1 including IGF binding protein-3, desmocollin II, Na/K ATPase, Bax, heat shock protein 70 and IGF-1 receptor. These genes are likely candidates 1) for developing assays for selection of embryos for transfer and 2) as marker genes for improving culture conditions for embryo production. The fact that IGF-1 improved survival of embryos in heat-stressed recipients only is consistent with the hypothesis that IGF-1 confers cellular thermotolerance to bovine embryos. Other experiments confirmed this action of IGF-1. One action of IGF-1, the ability to block heat-shock induced apoptosis, was shown to be mediated through activation of the phosphatidylinositol 3-kinase pathway. Other cellular determinants of resistance of embryos to elevated temperature were identified including redox status of the embryo and the ceramide signaling pathway. Developmental changes in embryonic apoptosis responses in response to heat shock were described and found to include alterations in the capacity of the embryo to undergo caspase-9 and caspase-3 activation as well as events downstream from caspase-3 activation. With the exception of IGF-1, other possible treatments to improve pregnancy rate to embryo transfer were not effective including selection of embryos for caspase activity, treatment of recipients with GnRH.and bilateral transfer of twin embryos. In conclusion, accomplishments achieved during the grant period have resulted in methods for improving post-transfer survival of in vitro produced embryos transferred into heat-stressed cows and have lead to additional avenues for research to increase embryo resistance to elevated temperature and improve survival to cryopreservation. In addition, embryo transfer of vitrified IVF embryos increased significantly the pregnancy rate in repeated breeder cows.
