Kinetically Limited Bulk Polymerization of Polymer Thin Films by Initiated Chemical Vapor Deposition.

An experimental study and kinetic model analysis of the initiated chemical vapor deposition (iCVD) of polymer thin films have been performed at saturated monomer vapor conditions. Previous iCVD kinetic studies have focused on subsaturated monomer conditions where polymer deposition kinetics is known to be limited by monomer adsorption. However, iCVD kinetics at saturated conditions have so far not been systematically investigated, and it remains unclear whether the adsorption-limited phenomenon would still apply at saturation, given the abundance of monomer for reaction.

Lipid membrane-mediated assembly of the functional amyloid-forming peptide Somatostatin-14.

Membrane-mediated assembly has been well characterised for toxic amyloid species such as the amyloid-β peptide implicated in Alzheimer's disease. However, little is known about the membrane-mediated assembly of functional-amyloid forming peptides, recently identified as a natural storage state for neuropeptide hormones in vivo. Here, we study the aggregation of somatostatin-14 (SST-14) co-incubated with model lipid membranes.

Visible-Light Driven Effective Photocatalytic Degradation of Methylene Blue Dye Using Perforated Curly ZnNiO Nanosheets.

Herein, we report the facile synthesis, characterization and visible-light-driven photocatalytic degradation of perforated curly ZnNiO nanosheets synthesized by hydrothermal process. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies confirmed the cubic phase crystalline structure and growth of high density perforated curly ZnNiO nanosheets, respectively. As a photocatalyst, using methylene blue (MB) as model pollutant, the synthesized nanosheets demonstrated a high degradation efficiency of ~76% in 60 min under visible light irradiation.

Enhanced Photocatalytic Performance of SnSiO Nanoparticles and Their Reduced Graphene Oxide (rGO) Nanocomposite.

Photocatalysts provide excellent potential for the full removal of organic chemical pollutants as an environmentally friendly technology. It has been noted that under UV-visible light irradiation, nanostructured semiconductor metal oxides photocatalysts can degrade different organic pollutants. The SnSiO/rGO nanocomposite was synthesized by a hydrothermal method.

Docking and molecular biology studies of -anisidine-appended 1-hydroxy-2-acetonapthanone Schiff base lanthanum(iii) complexes.

A new series of lanthanum(iii) complexes was synthesized using a -anisidine-appended 1-hydroxy-2-acetonapthanone (3) Schiff base and characterized spectroscopic methods. The ligand was synthesized sonication and the crystalline product was characterized using X-ray crystallography. The genotoxicity of the compound was assessed primarily by the bacterial reverse mutation (Ames) test and the mammalian chromosome aberration test; in both cases, the samarium complex 5 was found to be non-mutagenic.
