Hole Scavenging and Photo-Stimulated Recombination of Electron-Hole Pairs in Aqueous TiO2 Nanoparticles
It is shown that 532 nm and 1064 nm laser photoexcitation of trapped electrons generated by 355 nm photolysis of aqueous titania (TiO2) nanoparticles causes rapid photobleaching of their absorbance band in the visible and near IR. This photobleaching occurs within the duration of the laser pulse (3 ns FWHM); it is caused by photoinduced electron detrapping followed by rapid recombination of the...
متن کاملEffects of deep eutectic solvents in preparation of nanoparticles TiO2
Deep eutectic solvents (DESs) have always been attractive to scientists due to their wide range of applications, a great interest in diverse fields including nanotechnology due to their unique properties as new green solvents. It used large-scale for chemical and electrochemical synthesis nanomaterial. DESs have had also active role in improving the size and morphology of nanomaterial during sy...

متن کاملInactivation kinetics of horseradish peroxidase in organic solvents of different hydrophobicity at different water contents
The thermal stability of horseradish peroxidase suspensions was studied in three organic solvents of different hydrophobicity (dodecane, octane, and 1-octanol) at three different water contents (14.1, 55.3 and 256.2 mg water g dry protein). In these conditions, the enzyme is much more stable than in aqueous solutions (inactivation temperatures were in the range of 125–1508C). The enzyme showed ...
متن کاملInfluence of organic solvents on papain kinetics.
Papain activity was studied in water-organic solvent mixtures using the fluorogenic substrate Dabcyl-Lys-Phe-Gly-Gly-Ala-Ala-Edans. The increase of organic solvent (MeOH, EtOH, iPrOH, TFE, MeCN, (MeO)2Et and DMF) concentration in the mixture caused a substantial decrease the initial rate of papain-catalyzed hydrolysis. Moreover, the number of papain active sites decreased with the increase of D...
