Introduction. Non-ferrous smelters are one of the critical nanoscale cadmium particles sources in workplace and ambient air. Materials methods. The research was performed to evaluate subchronic toxicity oxide nanoparticles (CdO-NPs) white outbred rats. Male 3.5-month old rats received intraperitoneal injections CdO-NPs 3 times a week for six weeks (18 total) doses 0.25 mg/kg body mass. After en...

In 1935, shortly after moderate sized artificially grown crystals of magnesium oxide became available, two papers were published dealing with the optical properties of this material. 2 Strong and Brice measured the index of refraction of two prisms, cut from the same crystal, by photographic and visual means over the range from 2536 to 7065 A. Barnes, Brattain, and Seitz investigated the transm...

We have identified important chemical reactions that control the fate of metal-contaminated estuarine sediments if they are left undisturbed (in situ) or if they are dredged. We combined information on the molecular bonding of metals in solids from X-ray absorption spectroscopy (XAS) with thermodynamic and kinetic driving forces obtained from dissolved metal concentrations to deduce the dominan...

We show that thin film cadmium telluride (CdTe) solar cells exhibit the phenomenon of threshold switching similar to in phase change and resistive memory. It creates a conductive filament (shunt) through cell reaching buried electrode such as transparent oxide CdTe based photovoltaics (PV). While existing PV, was routinely contacted via laser scribe filled metals, our work paves way an alternat...

Ultralong beltlike (or ribbonlike) nanostructures (so-called nanobelts) were successfully synthesized for semiconducting oxides of zinc, tin, indium, cadmium, and gallium by simply evaporating the desired commercial metal oxide powders at high temperatures. The as-synthesized oxide nanobelts are pure, structurally uniform, and single crystalline, and most of them are free from defects and dislo...

Recent results of CRIEPI’s pyro-process fuel cycle technology developments are reported. On the actinides deposition into liquid cadmium cathode, a series of experiments are conducted using a small scale electro-refiner of about a hundred grams actinides inventory. The suitable condition for codeposition of U and TRUs is investigated, by varying Pu/U ratio in the salt from ∞ to 1.7. The design ...

The isolation of phosphatidyl choline which contains all of its nitrogen as choline, phosphorus as glycerophosphate, and has a relatively high iodine number, has posed a problem for some time. The most widely used method has been that of Levene and Rolf (l), as modified by Pangborn (24), wherein this lipide is isolated through a cadmium chloride complex. Sinclair (5) has described a procedure f...

Thin amorphous films of tungsten oxide (WO3) are well known to change their optical absorption behavior upon light exposure, usually referred to as photochromic effect. Since the formation of color centers is closely related to the optical creation of electron-hole pairs the sensitivity of the photochromic effect in WO3 is limited to energies above its band-gap energy of 3.25 eV, corresponding ...
