Lithium-rich disordered rocksalts such as Li 1.3 Nb 0.3 Mn 0.4 O 2 and MnO F are being investigated high energy density cathodes for next generation Li-ion batteries. They can support the (de) lithiation of lithium ions over large compositional ranges while preserving same overall structure. Here, we present a new Ni-rich oxyfluoride cathode, NiO F, with rocksalt deliver discharge capacity 200 ...

Amorphous semiconductors are materials with a brilliant prospect for a wide range of optical applications like solar cells, optical sensors, optical devices, and memories. The purpose of the present research was to study the semiconducting optical properties of SiO2-Al2O3-CaF2 and SiO2-Al2O3-BaF2 oxyfluoride...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

tumor growth is characterized by uncontrolled cell division. for centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional iranian and pakistani medicine for the treatment of melanoma and breast cancer. we have found that these nanocomposite particles are similar to silver nanoparticles (agnps) in size and shape and that there are so differenc...

A silicon oxyfluoride layer was deposited on a-Si samples using SiF 4 /O 2 plasma at different temperatures between −100°C and −40 °C. In situ X-ray photoelectron spectroscopy measurements were then performed to characterize the layer. The sample brought back room temperature analyzed again. It has been shown that a below −65 °C is needed significantly enhance physisorption of x species. Hence,...

archaeological researches indicate that the use of silver was common in various practices; there were numerous mints for silver coinage across sassanid persia (circa 620 ad) indicating that persians were familiar with silver mining and its refining process. medical practice also benefited from that expertise, and in the course of the following centuries new forms of utilizing silver began to em...
