Immobilized invertase studies on glass–ceramic support from coal fly ashes

Design and optimization of a microwave irradiated and resonant continuous biochemical reactor

“…The chosen reaction is the sucrose hydrolysis into fructose and glucose catalyzed by the invertase enzyme. The optimal temperature for it is 55°C [ Albertini et al, ; Bhatia et al, ], and the cavity design has been made at this temperature. Using , the height h of the cavity, for a resonant frequency at 2.45 GHz, must be equal to 107 mm.…”

“…The chosen reaction is the sucrose hydrolysis into fructose and glucose catalyzed by the invertase enzyme. The optimal temperature for it is 55°C [Albertini et al, 2013;Bhatia et al, 2012], and the cavity design has been However, (4) does not take fully into account the field inhomogeneity (which is different in the actual cavity from the empty one) and the losses. From the CST simulation of the full device (cavity and tubes), with a = 36.05 mm and h = 107 mm, we have, in fact, found that the resonant frequency of the TM 012 in the complete cavity is 2.749 GHz.…”

Crystalline phase evolution behavior and physicochemical properties of glass–ceramics from municipal solid waste incineration fly ash

“…Previous studies indicates that the melting or vitrification of fly ash has attractive potential applications for making glassceramics due to the volume reduction, weight reduction, and the value added utilization [9][10][11][12]. Even more important, heavy metals in fly ash are immobilized into a stable state, and the organic contaminants are thermally destroyed.…”

“…Even more important, heavy metals in fly ash are immobilized into a stable state, and the organic contaminants are thermally destroyed. For these reasons, glass-ceramics have been used as an environmentally-friendly alternative of natural stone in China, especially in the field of decorative building material [11][12][13].…”

Immobilizing nitrifying bacteria with Fe2O3‐CaO‐SiO2 porous glass‐ceramics

“…Porous carriers such as ceramics and glass‐ceramics are important microorganism immobilization carriers because of their large specific surface area, high strength and good biocompatibility . The technology of immobilized enzymes in porous ceramics is very mature; therefore, recent studies have been focusing more on immobilized bacteria in porous ceramics . The porous glass‐ceramics is also widely available and commonly used as medical materials, catalyst carriers as well as in wastewater treatment as filtration materials …”
