Microbioreactors for nutrient-controlled microbial cultures: Bridging the gap between bioprocess development and industrial use

It is common practice in the development of bioprocesses to genetically modify a microorganism and study a large number of resulting mutants in order to select the ones that perform best for use at the industrial scale. At industrial scale, strict nutrient-controlled growth conditions are imposed to control the metabolic activity and growth...

Mechanistic insight into the improved photocatalytic degradation of dyes for an ultrathin coating of SiO₂ on TiO₂ (P25) nanoparticles

The photocatalytic mechanism of TiO₂ (P25) nanoparticles coated with SiO₂ (SiO₂:TiO₂) by atomic layer deposition was investigated. The deposition of SiO₂ on TiO₂ not only gives a photocatalytic improvement for the degradation of both Rhodamine B (3.6–fold) and Acid Blue 9 (3...
