The atmospheric pressure chemical vapour deposition (APCVD) reaction of VCl4 and VOCl3 with cyclohexylphosphine at substrate temperatures of 600 C deposits thin films of amorphous vanadium phosphide. The films are black/gold, hard, chemically resistant and conductive. The APCVD reaction of MCl5 (where M = Nb or Ta) with cyclohexylphosphine at 500 C – 600 C deposits films of crystalline -MP ...

BACKGROUND Water treatment systems are a critical variable in dialysis therapy. Rigorous control of hemodialysis water quality is particularly important in order to guarantee a better quality of life of the hemodialysis patients. The objective of the study was to evaluate the chemical, microbiological quality and antimicrobial resistance of bacteria isolated from water and dialysate in a public...

Chemical studies of a streptomycete isolated from a cyanobacterium associated with the tropical tunicate Ecteinascidia turbinata led to the bioassay-guided purification of two antibacterial bisanthraquinone metabolites and a cytotoxic artifact. The structures, including relative configurations of these octacyclic compounds, were established by spectroscopic analyses. Their potent antibacterial ...

Background The emerging multidrug resistant (MDR) and extensively drug resistant (XDR) Mycobacterium tuberculosis (MTB) infection is increasing with greater complexity, estimated 220000-400000 tuberculosis cases emerged in 2011 globally. A number of lead compounds have been developed for treatment of MDR and XDR TB, but no new chemical entity has emerged for clinical use. Recently DprE1 and AHA...

It has been shown that a side population (SP), which is characterized by high chemical efflux capacity, is present in human melanoma cell lines. However, it was not clear whether patients' samples contain the same subpopulation. In this issue, Luo et al. (2012) report that they have isolated SP cells directly from patients' melanomas. SP cells are resistant to paclitaxel because of the upregula...

The ability of Klebsiella pneumoniae strains to resist the bactericidal activity of serum was quantitated. The K. pneumoniae strains tested included mutants lacking the capsular polysaccharide and mutants having a modified lipopolysaccharide structure. The last mutants were obtained as phage-resistant mutants, and their lipopolysaccharide was characterized by sodium dodecyl sulfate-polyacrylami...

Spoilage of heat processed food and beverage by heat resistant fungi (HRF) is a major problem for food industry in many countries. Neosartorya fischeri is the leading source of spoilage in thermally processed products. Its resistance to heat processing and toxigenicity makes studies about Neosartorya fischeri metabolism and chemical sensitivity essential. In this study chemical sensitivity of t...

P O L Y M E R S Our goal is to prevent the catastrophic failure of ballistic body armor by developing measurements and predictive models to test and determine the long-term reliability of polymers used in ballistic resistant armor. Our approach, which utilizes conventional analytical techniques in addition to newly developed minimally invasive test methods, seeks to identify the chemical and me...

Cultivar BRS A706 CL is a new rice cultivar, resistant to herbicides of the chemical group imidazolinones, with yield potential 15,635 kg ha-1. It has intermediate maturation, lodging tolerance, stay green trait, moderate blast resistance, high milling and premium grain quality.
