Nowadays, searching for the effective hydrogen (H2) storage/ generation materials remains one of the most difficult challenges toward a fuel-cell-based H2 economy as a longterm solution for secure energy in future. Formic acid (FA, HCOOH), a major product of biomass processing with highenergy density, nontoxicity, and excellent stability at room temperature, has recently attracted tremendous re...

Introduction: Adherent bacteria on orthopaedic implants are difficult to eradicate despite irrigation and treatment with IV antibiotics. This has led to the use of other irrigation solutions including surfactants (castile soap), antiseptics (povidine, chlorhexidine, hydrogen peroxide) and antibiotics (bacitracin, neomycin, and polymyxin). The mechanism of bacteria adhesion offers another yet un...

Electric vehicles and grid storage devices have potentialto become feasible alternatives to current technology, but only if scientists can develop energy storage materials that offer high capacity and high rate capabilities. Chemists have studied anatase, rutile, brookite and TiO2(B) (bronze) in both bulk and nanostructured forms as potential Li-ion battery anodes. In most cases, the specific c...

Hydrogen production in photoelectrochemical cells constitutes an important avenue toward carbon-free fuel. The most convenient process for hydrogen production is the splitting of water molecules, which necessitates a catalytic reaction involving a semiconductor. Here, we introduce a framework for the study of photocatalyzed reactions on semiconductor surfaces based on time-dependent density fun...

Introduction Controlled partial oxidation of natural products, such as terpenes, is one of the most important technologies to obtain cosmetic ingredients. For economic reasons, these processes mainly involve the use of molecular oxygen as the primary oxidant. Their success depends mostly on the use of a catalyst containing metal species in order to promote both the rate of reaction and the sele...

—Market-sized 2-year-old striped bass Morone saxatilis (average weight, 645 g) were evaluated in three different concentrations of Aqui-S at one of three different temperatures. Time to stage 4 of anesthesia, recovery time, and plasma cortisol level as an indicator of acute stress response, were determined. We found a significant difference in the time to stage 4 between 25 mg/L and 35 or 45 mg...

Polymers are widely used in the chemical synthesis of colloidal nanocrystals, and their roles are generally documented as steric stabilizers or capping agents. In particular, poly(vinyl pyrrolidone) (PVP) has received special attention because of its high chemical stability, nontoxicity, and excellent solubility in many polar solvents. Although the repeating unit of PVP has been extensively inv...

Different vegetable oil based biodiesel (FAMES) were prepared by alkaline transesterification using refined oils as well as waste frying oil (WFO). Methanol and sodium hydroxide are used as catalyst under similar reaction conditions. To ensure the quality of biodiesel produced, a series of different ASTM Standard tests were carried out. In this context, various testwere done including viscosity...

The present work describes the synthesis and characterization of PLA-co-EC copolymer from lactic acid and ethyl cellulose by azeotropic dehydration, under reduced pressure, at 140oC for 8 hours. The prepared PLA-co-EC copolymer was used for controlled drug release for an anticancer drug namely 6-Thioguanine with gold nanoparticles. Anticancer drug containing PLAco-EC copolymer nanocapsules were...

Poly(dimethylsiloxane) (PDMS) is the choice of material for a wide range of applications,1-3 because PDMS has many advantageous properties such as chemical inertness, nontoxicity, ease of handling, and commercial availability. It is impossible, however, to have one material that meets all the individual needs of microfluidic systems,1 micro-electromechanical systems (MEMS),2 and cellular study....
