Tank liquid ammonia (Ohio Chemical and Manufacturing Company) was distilled from sodium shavings into a tube of about 120 cc. volume. This was equipped with a thermocouple well, inlet and outlet side arms protected with calcium chloride and phosphorus pentoxide drying towers, and a standard taper cap containing a mercury seal stirrer. A current of dry nitrogen could be passed through the tube, ...

A molecular dynamics (MD) simulation has been carried out to explore the microstructure and diffusion pathway in amorphous vanadium pentoxide (V2O5) materials at room temperature ambient pressure. We showed that simulated model is a mix of basic units VO5 VO6 connected each other via 2 or 3 bridging oxygens. In model, there exist regions without atoms (cavity) form clusters channels. found 87% ...

Iodine pentoxide (I2O5), also known as diiodine pentoxide, is a strong oxidizer which has been recently proposed as an iodine-rich oxidizer in nanoenergetic formulations, whose combustion products lead to molecular iodine as a biocidal agent. However, its highly hygroscopic nature hinders its performance as a strong oxidizer and an iodine releasing agent and prevents its implementation. In this...

Mo/4H-SiC Schottky diodes were investigated as detectors for their suitability in photon counting X-ray and γ-ray spectroscopy. The diodes, with a 35μm thick n− epitaxial layer, treated phosphorus pentoxide surface passivation, which had been previously shown to improve the homogeneity of metal–semiconductor interface suppress leakage current. One device was coupled low-noise charge sensitive p...

The mid-low grade of phosphate ore, rich by the silicate and carbonate gangue minerals needs a special treatment using flotation process. Where collectors play pivotal role. This study was conducted to enrich an untreated ore (without washing, desliming, hydrocycling, etc.), with eco-friendly economic collector based on soybean oil. Different analytical techniques such as UV-Visible, ATR-FTIR s...

In recent times there has been a growing interest in the development of quasi-two-dimensional niobium pentoxide (Nb2O5) as a semiconductor for the potential electronic applications such as capacitors, filtration, dye-sensitised solar cells and gas sensing platforms. Therefore once the purpose is established, Nb2O5 can be prepared in a number of nanoand sub-micron-structural morphologies that in...

We present optical and morphological characterizations performed on thermochromic V2O5 coatings. V2O5 coatings were obtained by oxidation of as-deposited VOx films. Comparisons were made among coatings oxidized at various temperatures. Photographic evidence is also shown to provide the reader a clear visual description of the color change that occurs during thermochromic process. Detailed study...
