lipases is uncharged due to other active site differences and does not cause the same distortion. This example of the fine tuning of the same catalytic triad for different types of catalysis by subtle interactions with other active site residues shows how difficult it is to design new catalytic reactions of enzymes.
We report efficient panchromatic light harvesting by co-adsorption of a porphyrin molecule and N719 in dye-sensitized solar cells. The co-sensitized device shows a considerably enhanced power conversion efficiency of 8.89%, while those individually sensitized by porphyrin and N719 display efficiencies of 7.21% and 8.0…
The reversible inhibition of laccase by H 2 O 2 as a bioelectrocatalyst was studied in mediated- and direct electron transfer-based configurations to understand the differences in mechanism. The reversible inhibition of laccase follows a noncompetitive inhibition model when 2,2 ' -azino-bis(3-ethylbenzothiazoline-6-su…
Organotin (IV) carboxylates with the general formulae R2Sn(Cl)L [R = Me (1), n-Bu (2), Ph (3)] and R3SnL [R = Me (4), Ph (5)] have been synthesized by the reaction of 4-piperidinecarboxylic acid (HL) with KOH and R2SnCl2 (R = Me, n-Bu, Ph)/R3SnCl (R = Me, Ph) in methanol under stirring conditions. The metal ligand bin…
A facile naphthalene-based Schiff base chemosensor, 1-((pyridin-2-ylmethylimino)methyl)naphthalen-2-ol, has been designed and synthesized for selective detection of Zn 2+ ions.
SnO 2 /C microspheres and double layered core–shell SnO 2 microspheres can be synthesized in large scale by a facile hydrothermal method followed by heat-treatment.
We developed a simple, rapid and sensitive fluorescence method for the direct detection of cancer cells using a GO-based aptasensor.
Ternary blends of C 60 , C 70 and a thiophene–quinoxaline copolymer (TQ1) can be readily processed from solution. A solar cell efficiency of 3.6% is achieved with a 2 : 1 : 1 TQ1:C 60 :C 70 mixture, accompanied by a high internal quantum efficiency of 75%.
) covalently bound to surfaces rendered them sufficiently resistant to an Enterobacter cloacae inoculum and its adherent biofilm. Compared to unmodified surfaces, up to a 30-fold reduction in bacterial attachment was achieved with this coating technology. The immobilization of chlorhexidine was verified with infrared…
The performance of bulk heterojunction solar cells based on a novel donor polymer DPP-TT-T was optimised by tuning molecular weight and thermal annealing.
We have identified the most probable precursor for the formation of Li 2 O 2 nanoparticles on the α-MnO 2 (100) surface.
Through photoreduction, superfine copper nanoparticles were prepared form a high concentration of copper chloride at room temperature in the presence of the capping agent PEI.
Driven by molecular affinity and balance in the crystallization kinetics, the ability to co-crystallize dissimilar yet self-crystallizable blocks of a block copolymer (BCP) into a uniform domain may strongly affect its phase diagram. In this study, we synthesize a new series of crystalline and monodisperse all-π-conju…
Herein various AgCl microstructures including octapods, octapods with fishbone pods, hexapods, hexapods with 4-blade arrowhead pods, concave octahedra, and octahedra are selectively precipitated from a [Ag(NH 3 ) 2 ] + solution by addition of Cl − .
The electrochemical redox of ferulic acid (FA) was investigated systematically by cyclic voltammetry (CV) with a poly(diallyldimethylammonium chloride) functionalized graphene-modified glassy carbon electrode (PDDA-G/GCE) as a working electrode. A simple and sensitive differential pulse voltammetry (DPV) technique was…
Structural, optical, and photocatalytic properties of TiO2and TiO2:Nd nanopowders and thin films composed of those materials have been compared. Titania nanoparticles with 1, 3, and 6 at. % of Nd-dopant were synthesized by sol-gel method. Additionally, thin films with the same material composition were prepared with t…
Efficient ion transport was achieved from crown ether amphiphile-based ion channels by simply regulating the molecular structures.
The selectivity of the aerobic oxidation of aldehydes can be strongly enhanced by means of a synergistic use of salts and catalyst.
The excellent mechanical properties and chemical stability of titanium and its alloys have led to their wide use as a material for dental and orthopaedic implants. However, the bio-inert nature of these materials must be overcome to enhance cell affinity and cell function following implantation. Effective implants req…
Garments washing is a novel process to impart worn-out look, to modify the appearance and to improve the comfort ability of the garments. Bleach wash is used to fade the color of denim in a higher degree as well as bleach wash has effect on the physical and mechanical properties of the denim also. This paper presents…
