cupric oxide nanostructures were synthesized via a simple reaction between copper nitrate and sodium hydroxide using a sonochemical-assisted method. the synthesized cuo was then characterized using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fourier transform infrared, ultraviolet-visible and photoluminescence spectroscopy. our studies show that the cuo na...

Despite the significant contributions of tissue culture and bacterial models to toxicology, whole animal models for developmental neurotoxins are limited in availability and ease of experimentation. Because Drosophila is a well understood model for embryonic development that is highly accessible, we asked whether it could be used to study methanol developmental neurotoxicity. In the presence of...

Methanol poisoning is an uncommon but an extremely hazardous intoxication. Since methanol is a versatile fuel and is having increasing usage in an energy-conscious society, a high index of suspicion and swift laboratory confirmation is essential in managing this poisoning. Methanol poisoning may occur in sporadic or epidemic circumstances. Chronic exposure may occur in the occupational setting....

The metabolism of methanol was monitored in whole cells of the methylotrophic yeast Hansenula polymorpha by using [13C]methanol and n.m.r. in vivo. The main products observed under normal conditions were trehalose and glycerol, whereas cells that were starved before exposure to [13C]methanol also accumulated glutamate, glutamine and alanine; formate was also more prominent in spectra from starv...

Liquid methanol and methanol clusters have been comprehensively studied to reveal their local structure and hydrogen bond networks. However, our understanding of the crystal forms of methanol is rather limited. The known crystal structures of solid methanol, α, β, and γ, are composed of infinite hydrogen bond chains in their unit cell. The structural diversity of solid methanol is much less tha...

Methanol is considered an interesting carbon source in "bio-based" microbial production processes. Since Corynebacterium glutamicum is an important host in industrial biotechnology, in particular for amino acid production, we performed studies of the response of this organism to methanol. The C. glutamicum wild type was able to convert (13)C-labeled methanol to (13)CO2. Analysis of global gene ...

Abstract A singlet oxygen production was monitored using a sensor green chemical probe; reaction of probe with produces fluorescent endoperoxide. Adding ethanol to the irradiated system resulted in decrease fluorescence signal, which indicates concentration formed under UV-C irradiation. Thus, likely quench study. This quenching did not occur use methanol. When irradiating E. coli cells presenc...

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...
