For semiconductor tin dioxide (SnO2) materials, the oxygen adsorption theory often struggles to explain their selectivity towards specific gases. Therefore, it is worth considering altering surface functional groups of SnO2 modify its state and enhance Due rich on surfaces carbon dots, this study employed a hydrothermal method prepare three types dots with varying carboxyl group contents by adj...

The interactions of the carboxyl group of oleic acid with bovine serum albumin (BSA) were studied by 13C NMR spectroscopy at 50.3 MHz using 90% isotopically substituted [1-13C]oleic acid. 13C NMR spectra were obtained as a function of the mole ratio of oleic acid to BSA (from 0.5-10.0) and, for selected mole ratios, as a function of pH (between pH 3.0 and 10.6) and temperature (between 15 and 5...

The immobilization of cross-linked tannase onto carboxyl-functionalized multi-walled carbon nanotubes (MWCNT-COOH) was achieved via physical adsorption. Glutaraldehyde used to cross-link the enzyme molecules. Spectroscopic and morphological characterizations enzyme-nanotubes composite were carried out, which authenticated successful adsorption event. Enzyme is proven equal to, or even superior ...

Strain is eliminated as a factor in hydrolysis of the scissile peptide bond by human immunodeficiency virus (HIV)-1 and simian immunodeficiency virus (SIV), based on the first eight complexes of products of hydrolysis with the enzymes. The carboxyl group generated at the scissile bond interacts with both catalytic aspartic acids. The structures directly suggest the interactions of the gemdiol i...

Self-assembling films typically used for colloidal lithography have been applied to pine wood substrates change the surface wettability. Therefore, monodisperse polystyrene (PS) spheres deposited onto a rough substrate via dip coating. The resulting PS sphere film resembled polycrystalline face centered cubic (FCC)-like structure with typical domain sizes of 5–15 single spheres. This self-assem...
