The exacting selectivity of enzymatic catalysis is the most valuable characteristic of enzymes to the synthetic chemist. Ironically, this strict specificity also limits the generality of enzymatic synthesis, because enzymes that catalyze the reaction of interest with the desired selectivity are not always available. Nonaqueous enzymology, and the discovery that enzymatic selectivity can be chan...

This work presents a novel method for the accurate determining trans- and cis-resveratrol (3,5,4'-trihydroxystilbene) by nonaqueous capillary electrophoresis/fluorescence spectroscopy at 77 K. The proposed method permits not only the separation of resveratrol isomers, but also ensures that on-line spectra are readily distinguishable and unambiguously assigned. The experimental results also indi...

Metal oxide nanoparticles can be fabricated under high control via nonaqueous sol-gel synthesis. This route has been shown to lead to highly crystalline, uniform nanostructures, which explains the high and growing interest it is receiving. The underlying mechanisms are, however, so far only rudimentarily understood on a molecular scale. Here, we applied in situ FTIR spectroscopy and other techn...

Iron porphyrins have high activity and selectivity for electrocatalytic CO2 reduction reaction (CO2RR) in nonaqueous solutions, but they usually display poor or moderate CO2RR aqueous solutions because of the competitive hydrogen evolution reaction. Using water as solvent is more favored not only it cheap, green abundant also can sufficiently provide protons required CO2RR. Therefore, developin...

answer. However, there is no reason why reactions cannot be carried out on such devices. Since it does not require the investment of a large chemical plant, the reactions can be performed where required, thus reducing the need to transport hazardous chemicals across countries. Since many reactors can be constructed on a single chip, and many chips located in the same area, it is evident that th...

Polymeric particle dispersions have numerous potential applications; currently one of the most relevant is their use as inks in electrophoretic displays. These colloidal particles are synthesized from the appropriate monomer using nonaqueous dispersion (NAD) polymerization in a nonpolar solvent, which requires a stabilizer to control particle size and morphology. We have previously reported the...

There are a variety of approaches to removing gaseous pollutants from effluent streams: absorption, adsorption, condensation, chemical reaction, incineration, and selective diffusion through a membrane. Absorption is an operation involving mass transfer of a soluble vapor component to a solvent liquid in a device that promotes intimate contact between the gas and the liquid. The driving force f...
