The influence of microstructure on the mechanical properties of some refractory compounds
A brief review of the basic physics of electron energy loss spectroscopy and extended x-ray absorption fine structure spectoscopy is presented in the context of their application to the study of the microstructure of transition metal carbides and diborides. The local atomic structure of amorphous …

Conventional and Advanced Thermal Hydrolysis in Sewage Sludge Pre-treatment
… increase the formation of ammonia nitrogen and refractory compounds in the treated sludge. These compounds act as inhibitors of methanogenesis, significantly impacting methane production in anaerobic digestion processes. Advanced thermal hydrolysis (ATHP), an oxidative thermal hydrolysis …
