By using carbamide granules as the space holder, Mg alloy foams with interconnected pore structures were synthesized by reactive sintering of a mixture Mg, Al and Zn powders. The effect Zn/Al on microstructural evolution compressive strength porous Mg-9Al-xZn (x = 1, 5) was investigated. phase diagram simulation approach used to determine temperature. analysis results show that formation binary...

The fabrication of 3D ink-printed and sintered porous Si scaffolds as electrode material for lithium-ion batteries is explored. A hierarchically-porous architecture consisting channels (~220 μm in diameter) between microporous struts created to accommodate the large volume change from (de)lithiation during electrochemical (dis)charging. influence sintering parameters on strut porosity resulting...

New innovative approach to fabricate porous alumina ceramics by cold sintering process (CSP) is presented using NaCl as pore forming agent. The effects of CSP and post-annealing temperature on the microstructure mechanical strength were investigated. Al2O3–NaCl composite with bulk density 2.92 g/cm3 was compacted firstly then a structure formed at 1200°C–1500°C for 30 min. Brazilian test method...

Bone tissue engineering offers promising alternatives to repair and restore orthopaedic disorders. Our laboratory has employed poly(lactic acid-co-glycolic acid) (PLAGA) microspheres to develop a three dimensional (3-D) porous bioresorbable scaffold with a pore structure similar to the structure of human trabecular bone. The success of osseous healing and integration of the engineered implants ...

The influence of mineral substrate composition and structure on bacterial calcium carbonate productivity and polymorph selection was studied. Bacterial calcium carbonate precipitation occurred on calcitic (Iceland spar single crystals, marble, and porous limestone) and silicate (glass coverslips, porous sintered glass, and quartz sandstone) substrates following culturing in liquid medium (M-3P)...
