Porous silicon nitride–based drug delivery carrier Michal Hičák, Ľubomír Medvecký, Miroslav Hnatko, Radoslava Stulajterová, Mária Giretová, Monika Tatarková, Zoltán Lenčéš, Pavol Šajgalík Abstract Tetracalcium phosphate/monetite biocement was modified with the addition of 30 wt% highly porous silicon nitride/α-tricalcium phosphate (α-TCP) microgranules. The volume ratio of Si3N4 and α-TCP in microgranules was 1:1 and showed good… Continue reading Porous silicon nitride–based drug delivery carrier

Physical properties of feeds for novel bioactives – encapsulating bead formation Hansen, Mackenzie M. Abstract Encapsulation involves the entrapment of sensitive bioactive compounds with structure- forming food components to enhance protection and delivery. Blends of proteins and glass- forming carbohydrates are often used as encapsulation matrices and for structure formation. When bioactives intended for encapsulation… Continue reading Physical properties of feeds for novel bioactives – encapsulating bead formation

Sintering and microstructure development of SFR MOX nuclear fuel Julie Simeon Abstract For the manufacture of FNR (Fast Neutron Reactor) MOX (Mixed Oxide) fuel, (U,Pu)O2-x, consolidation of green compacts shaped from the raw powders, is performed by sintering at high temperature. Thus, the detailed study of the sintering is based on coupling of dilatometric tests… Continue reading Sintering and microstructure development of SFR MOX nuclear fuel

Formation of dry beads for bioactives encapsulation by freeze granulation Mackenzie M. Hansen, Richard W. Hartel, Yrjö H. Roos Abstract Solid beads formed by whey protein isolate (WPI) and various sugars/polyols with a wide range of glass transition temperatures showed potential as structures for encapsulation of Aronia berry bioactives. Whey protein isolate (WPI), Aronia extract,… Continue reading Formation of dry beads for bioactives encapsulation by freeze granulation

Porous silicon nitride-based drug delivery carrier Hicak, Michal; Medvecky, L’ubomir; Hnatko, Miroslav; Stulajterova, Radoslava; Giretova, Maria; Tatarkova, Monika; Lences, Zoltan; Sajgalik, Pavol Abstract Tetracalcium phosphate/monetite biocement was modified with the addition of 30 wt% highly porous silicon nitride/alpha-tricalcium phosphate (alpha-TCP) microgranules. The volume ratio of Si3N4 and alpha-TCP in microgranules was 1:1 and showed good… Continue reading Porous silicon nitride-based drug delivery carrier

Formulation of mixed alumina/kaolin systems : Application to the elaboration of multi-layer materials by co-pressing Rana Al Tahan Abstract Multilayer ceramic architectures generally exhibit improved mechanical properties in regards with individual monolithic constituents. In alumina-based materials, addition of kaolin can advantageously promote i) mullite crystallisation and ii) internal residual stresses by monitoring thermal expansion mismatch… Continue reading Formulation of mixed alumina/kaolin systems : Application to the elaboration of multi-layer materials by co-pressing

Modified Freeze-granulation method for fabricating Li2TiO3 ceramic tritium breeding pebbles Shufeng Zhang, Wei Lu, Youfu Jiang, Xinyu Gao, Delin Chu, Weihua Wang Abstract Lithium metatitanate (Li2TiO3) ceramic is an important candidate for tritium breeding material in fusion reactor blanket. Nevertheless, mass production has become an important factor restricting the application of Li2TiO3 pebbles. In this… Continue reading Modified Freeze-granulation method for fabricating Li2TiO3 ceramic tritium breeding pebbles

Enhancing the density and crush load of Li2TiO3 tritium breeding ceramic pebbles by adding LiNO3-Li2CO3 Yichao Gong, Qingze Na, Chao Dang, Yijiang Yang, Mingxiang Tang, Zhanwen Liu, Guojun Zhang Abstract The fabrication of Li2TiO3 ceramic pebbles with satisfactory density and excellent crush load while maintaining a fine grain structure is one of the research objectives… Continue reading Enhancing the density and crush load of Li2TiO3 tritium breeding ceramic pebbles by adding LiNO3-Li2CO3

Comparative sintering behaviour of MOX powders synthesized through the freeze granulation or dry-cogrinding routes Guillaume Bernard-Granger, Florent Lebreton, Laure Ramond, Marion Le Guellec, Gabriella Cunha Costa Miranda, Abibatou Ndiaye, Thierry Gervais Abstract Two MOX powders containing 11 mol% Pu/(U+Pu) have been synthesized using the freeze granulation or dry-cogrinding routes. The sintering behaviour of green compacts has… Continue reading Comparative sintering behaviour of MOX powders synthesized through the freeze granulation or dry-cogrinding routes
