Reactions of thorium tetrahalides ThX4 (X=Cl, Br, I) with liquid ammonia at room temperature lead to the formation decaammine thorium(IV) halide ammoniates. Their different compositions [Th(NH3)10]X4 ? nNH3 were established by single crystal X-ray diffraction. While for chloride a tetraammoniate is observed, reaction bromide leads an octaammoniate, whereas iodide results in approximately nonaam...
Higher concentrations of ammonia (NH3) and carbon dioxide (CO2) in animal barns can negatively affect production and health of animals and workers. This paper focuses on measurements of summer concentrations of ammonia (NH3) and carbon dioxide (CO2) in a naturally ventilated laying henhouse located at an egg production facility in Bursa region, western Turkey. Also, indoor and ambient environme...
Improved data on biosphere-atmosphere exchange are fundamental to understanding the production and fate of ammonia (NH3) in the atmosphere. The GRAMINAE Integrated Experiment combined novel measurement and modelling approaches to provide the most comprehensive analysis of the interactions to date. Major intercomparisons of micrometeorological parameters and NH3 flux measurements using the aerod...
1984 Methane (CH4) and ammonia (NH3) are emitted to the atmosphere during anaerobic processing of organic matter, and both gases have detrimental environmental eff ects. Methane conversion to biofuel production has been suggested to reduce CH4 emissions from animal manure processing systems. Th e purpose of this research is to evaluate the change in CH4 and NH3 emissions in an animal feeding op...
Nutritive values of green and black tea by-products and anti-nutritive activity of their tannins were evaluated in an in vitro rumen fermentation using various molecular weights of polyethylene glycols (PEG), polyvinyl pyrrolidone (PVP) and polyvinyl polypyrrolidone as tannin-binding agents. Significant improvement in gas production by addition of PEG4000, 6000 and 20000 and PVP was observed on...
To access the fermentative response of equine caecal microbial population to nitrogen availability, an in vitro study was conducted using caecal contents provided with adequate energy sources and nitrogen as limiting nutrient. Two nitrogen (N) sources were provided, protein (casein) and non-protein (urea). Caecal fluid, taken from three cannulated horses receiving a hay-concentrate diet, was mi...
Ammonia (NH3) is produced from atmospheric nitrogen and hydrogen from a hydrocarbon source. Natural gas is the most commonly used hydrocarbon feedstock for new plants; other feedstocks that have been used include naphtha, oil, and gasified coal. Natural gas is favored over the other feedstocks from an environmental perspective. Ammonia production from natural gas includes the following processe...
A combination of the functionalities of carbon nanotube (CNT)-Si hybrid heterojunctions is presented as a novel method to steer the efficiency of the photovoltaic (PV) cell based on these junctions, and to increase the selectivity and sensitivity of the chemiresistor gas sensor operated with the p-doped CNT layer. The electrical characteristics of the junctions have been tracked by exposing the...
Laser initiated, free standing discharge channels offer many attractive advantages for the transport and focusing of intense ion beams [1, 2]. Discharge plasmas can neutralize both current and space charge of such beams, while the azimuthal magnetic field provides strong focusing all the way through the channel. Experiments at GSI have produced 50 cm long stable plasma channels with peak curren...
Coal splitting and reburning is a promising technology to control NO emissions during coal combustion. During this process, pyrolysis gas used as reburn fuel convert N2. Nitrogen-containing compounds (HCN NH3) play dominant roles in the reduction performance. In study, we investigated influence of nitrogen-free species (CH4, CO H2) on by HCN NH3 via reactive force field (ReaxFF) molecular dynam...
