Volatile organic compounds (VOCs) emitted from industrial processes have high stability, low activity, and toxicity which cause continuous harm to human health the atmospheric environment. Catalytic combustion has advantages of energy consumption cost is expected be one most effective methods remove VOCs. At present, selection cost, durability catalysts are still a difficult problem. Industrial...

Volatile organic compounds (VOCs) that evaporate under standard atmospheric conditions are of growing concern. This is because it well established VOCs represent major contamination risks since release these into the atmosphere can contribute to global warming, and thus, also be detrimental overall health worldwide populations including plants, animals, humans. Consequently, detection, discrimi...

High efficiency Si heterojunction (HJ) solar cells must exhibit low interface recombination, as it limits the cell open circuit voltage (VOC). The study of the interface recombination of various a-Si:H/c-Si lifetime test samples gives insight into the recombination mechanisms, which are found compatible with an amphoteric recombination model [1]. We find that there is a trade-off between reduce...

Six rhizobacteria isolated from common bean and able to protect bean plants from the common bacterial blight (CBB) causal agent, were in vitro evaluated for their potential antifungal effects toward different plant pathogenic fungi, mostly soil-borne. By dual culture assays, the above bacteria resulted producing diffusible and volatile metabolites which inhibited the growth of the majority of t...

T he atmospheric chemistry that leads to photochemical smog and climateactive aerosols requires the presence of volatile organic compounds (VOCs) (1, 2). The VOCs in urban air typically derive from the prevailing energy and transport technologies as well as the use of petrochemical-derived products. On page 760 of this issue, McDonald et al. (3) report that a notable change in emissions may be ...

Oil and gas production from organic-rich shale formations has become viable through advancements in multistage hydraulic fracturing. However, fluctuations oil prices, coupled with the sharp decline after initial days of fracturing operations, drive operators to devise strategies for enhancing hydrocarbon production. The use highly reactive fluids that include strong oxidizing agents, also known...

Virtual Organization Clusters (VOCs) provide a novel architecture for overlaying dedicated cluster systems on existing grid infrastructures. VOCs provide customized, homogeneous execution environments on a per-Virtual Organization basis, without the cost of physical cluster construction or the overhead of per-job containers. Administrative access and overlay network capabilities are granted to ...

In plant-associated Pseudomonas species, the production of several secondary metabolites and exoenzymes is regulated by the GacS/GacA two-component regulatory system (the Gac-system). Here, we investigated if a mutation in the GacS sensor kinase affects the production of volatile organic compounds (VOCs) in P. fluorescens SBW25 (Pf.SBW25) and how this impacts on VOCs-mediated growth promotion a...

Background: Diagnoses  of  respiratory  tract  infections  usually happen  in  the  late  phase  of  the  disease  and  usually  result  in  reduction  of  the  pathogen  load after broad-spectrum  antibiotic  therapy,  but  not  in eradication of the pathogen.  The  development  of a  non-invasive,  fast,  and  accurate  method  to  detect  pathogens  has  always  been  of  interest  to  resea...
