X-ray absorption spectra (XAS) were collected and analyzed to characterize bismuth (Bi) environments in borosilicate glass formulations developed for the immobilization of high level nuclear wastes (HLW), from the bismuth phosphate process. Therefore, the structural role of Bi in these glasses is of interest; in addition in the present study, more particular interest in Bi originated from unusu...

Creation of foam structures from hydrolytically degradable poly(ε-caprolactone) (PCL) is a current task in biomaterial research. One example are degradable scaffolds. The thermodynamic and kinetic conditions in a supercritical CO2 (scCO2) supported foaming process of PCL can influence the resulting morphology of the foam. PCL-foaming with scCO2 was systematically investigated in the pressure ra...

Abstract This research presents the possibility of producing durable foam glasses from glass cullet using SiC/AlN foaming agent. The agent generated by SiC and AlN couple results in a more homogeneous microstructure thus emergence with better properties compared to nitride used alone our previous work. fabricated had crack-free, 3-D cellular structure macropores whose geometries varied between ...

Latex is one of the natural rubbers that used to enhance performance asphalt pavement for last few decades. The presence latex, which categorized as an elastomer, helps improve and durability. Conversely, higher viscosity latex modified binder increases production-temperatures mixture, thus consuming energy during mixture’s production stage. In this study, effectiveness methanol energy-efficien...

Aluminum metal foam has become an advanced popular material because it excellent mechanical and electrical properties is lightweight. The present work developed the Aluminium specimen using wax powder as a blowing agent through metallurgy method. effect of process parameters such size, stirring speed, sintering temperature, foaming content on behavior specimens been studied experimentally. In d...

This study deals with the effect of gelatin on physical and mechanical properties of  calcium phosphate bone cements. The mixture of tetracalcium phosphate (TTCP) and dicalcium phosphate (DCPA) as the cement powder was mixed with 6 wt% Na2HPO4 solution containing different amount (0, 2, 5 and 8% in w/w) of foamed gelatin as liquid phase. The physical properties were determined in the terms of s...
