Carbon-SnO2 core-shell hybrid nanofibers were prepared via single-spinneret electrospinning and subsequent heat treatment. The Kirkendall effect during the heat treatment is found to be responsible for the formation of c...
A Co(II)-Cu(II) framework based on a paramagnetic metalloligand [Co(Tt)(2)] shows a permanent porosity with a record high surface area for magnetic MOFs as well as a reversible magnetic transformation between a paramagne...
High Pt utilization PEMFC electrodes were prepared by an alternative ion-exchange/electrodeposition (AIEE) technique. The results demonstrated that the MEA employing an AIEE electrode with a Pt loading of 0.014 mg Pt cm(...
Monoclinic CuO crystallite in grams has been obtained from resin bound Cu(II)-1,10-phenanthroline complex, R-[Cu(1,10-phen)(2)](2+) that becomes a recyclable catalyst for oxidative phenol coupling (OPC) reaction. Thus an...
Redox couples based on cobalt complexes were found to be effective in regenerating both inorganic CdSe quantum dot-and organic dye-sensitizers. The hybrid sensitizer composed of CdSe QD and ruthenium sensitizer (Z907Na) ...
In water, phosphoric membrane molecule (V-) self-assembled to form an anionic giant vesicle, the surface of which served as a catalyst for the autocatalytic formation of V- from its membrane precursor (V-star), and the a...
The side-on end-on dinitrogen complex [PhP(CH2SiMe2NPh)(2)Ta](mu-H)(2)(mu-eta(2):eta(1)-N-2) reacts with CS2 with complete cleavage of both C=S double bonds and the formation of [PhP(CH2SiMe2NPh)(2)Ta](mu-S)(2)(mu-CH2), ...
We report here, for the first time, a biotemplated synthesis of uniform CdSe nanoparticle (4.1 +/- 0.5 nm) and a fabrication of two-dimensional CdSe nanoparticles (over one micrometre) with nanometric gaps by cage-like p...
It was found that the chemiluminescence of acridinium ester (AE) was quenched effectively by gold nanoparticles (AuNPs) with Stern-Volmer constants approaching 10(10) M-1, which was exploited to realize sequence-specific...
We report the computational enzyme design of an orthogonal nucleoside analog kinase for 30-deoxythymidine. The best kinase variant shows an 8500-fold change in substrate specificity, resulting from a 4.6-fold gain in cat...
Among three noble-metal-free molecular devices (1-3) containing a porphyrin photosensitizer and a cobaloxime catalyst, the one with a zinc porphyrin unit displayed apparently higher efficiency for photoinduced H-2 produc...
Xenobiotic reductase A (XenA) has broad catalytic activity and reduces various alpha,beta-unsaturated and nitro compounds with moderate to excellent stereoselectivity. Single mutants C25G and C25V are able to reduce nitr...
Using commercially activated carbon, we developed a simple and effective direct chemical oxidation route to prepare good biocompatible multicolor photoluminescent carbon dots.
Coesite nanocrystals have been synthesized from periodic mesoporous organosilica (PMO) with (CH2)(2) bridges heated at 300 degrees C for 150 min and 12 GPa. The crystals are not sintered, single crystalline, and have dia...
A new kind of silver micro-dendrites with no surfactants protected has been synthesized for the separation and detection of DNA merely by earth gravity as the density of silver is larger than that of water. Through this ...
