Improving ORR Activity of Nitrogen-Doped Carbon Catalysts via Washing PANI-iron Coordination Precursor with ethanol

open access: yesInternational Journal of Electrochemical Science, 2019
Effectively improving catalytic activity of nitrogen (N)-doped carbon catalysts in oxygen reduction reaction (ORR) is very important but still facing with challenges. Herein, we proposed a “solvent effect” strategy to prepare a high active N-doped carbon

Effect of Organic Solvent on the Enzyme Bleaching Agent System

open access: yes, 2002
P(論文)The Orange n decoloration reaction in the presence of various organic solvents with the HRP-H_2O_2 system was examined. In 5% organic solvent mixing aqueous solutions, the decoloration rates of Orange n were about 0.9-0.5 times of those in the ...

Analysis of the Behavior of Deep Eutectic Solvents upon Addition of Water: Its Effects over a Catalytic Reaction

open access: yesMolecules
This study presents the potential role of deep eutectic solvents (DESs) in a lipase-catalyzed hydrolysis reaction as a co-solvent in an aqueous solution given by a phosphate buffer. Ammonium salts, such as choline chloride, were paired with hydrogen bond

Solvent effect on the debromination/dehydrobromination of bromo-damascone

open access: yes, 2016
The dehydrogenative synthesis of -damascenone from -damascone via the related allyl bromide intermediate was studied in depth. The requisite dehydrobromination thereof was found strongly solvent system dependent.

Microemulsion breakdown by pervaporation technique: Effect of the alkyl chain length of n-alkanol, a cosurfactant of the microemulsion [PDF]

open access: yes, 2007
Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol.

Solvent-Cage Effect (Viscosity Dependence) as a Diagnostic Probe for the Mechanism of the Intramolecular Chemically Initiated Electron-Exchange Luminescence (CIEEL) Triggered from a Spiroadamantyl-Substituted Dioxetane

open access: yes, 2016
The excitation step of the intramolecular CIEEL generation in the triggered cleavage of spiroadamantyl-substituted dioxetane has been studied. The electron back-transfer (BET) process versus the direct chemiexcitation of the phenolate-anion emitter have ...

Study the Effect of Solvent / Non-solvent on Polycarbonate [PDF]

open access: yesAmerican Journal of Nanosciences, 2017
A stable superhydrophobic PC surface was obtained by a simple phase separation method at room temperature. The water contact angle of the superhydrophobic PC surface is 156± 2°. FESEM image exhibited that the PC surface composed of flower-like shaped linked together centrally with branches offered roughness on the surface with a hierarchical micro/nano-
