A series of compounds with the composition Na(3-x)Sn(2-x)Sb(x)NaO6 (x = 0.0, 0.2, 0.4, 0.6, 0.7, 0.8, 0.9, and 1.0) has been prepared by solid-state reaction and characterized by powder X-ray diffraction, neutron diffraction (for x = 0.0), and impedance spectroscopy. The compounds have a layered structure derived from that of α-NaFeO2, with alternating Na3 planes and NaSn2O6 slabs with honeycom...

Chemical energy storage using batteries will become increasingly important for future environmentally friendly ('green') societies. The lithium-ion battery is the most advanced energy storage system, but its application has been limited to portable electronics devices owing to cost and safety issues. State-of-the-art LiFePO4 technology as a new cathode material with surprisingly high charge-dis...

The paper presents the method of plasma-assisted deposition AlMgB14 films in a discharge system that consisted large volume gas plasma generator with thermionic and hollow cathode. An electrode BAM powder was placed plasma. High-frequency voltage 13.56 MHz applied to powder. In contrast traditional RF magnetron deposition, use made it possible significantly increase rate for reduce pressure wor...

Fast Li-ion-conducting Li oxide garnets receive a great deal of attention as they are suitable candidates for solid-state Li electrolytes. It was recently shown that Ga-stabilized Li7La3Zr2O12 crystallizes in the acentric cubic space group I4̅3d. This structure can be derived by a symmetry reduction of the garnet-type Ia3̅d structure, which is the most commonly found space group of Li oxide garne...

The paper presents an analysis of the heat transfer processes in electric arc plasma conditions between powder material and jet different convective states. generated for coating deposition are considered based on varying jet–powder interaction. formed deposited onto substrate acts as indicator efficiency. is facilitated by turbulent nature jet. presented calculation results demonstrate influen...

BiOI nanosheets are easily synthesized by direct thermal treatment of commercial BiI3 powder, serving as a novel anode material for lithium-ion batteries. A high volumetric capacity of ∼5678 mA h cm(-3) was achieved. This work demonstrates that the BiOI nanosheets hold great promise as high-energy anode material for lithium-ion batteries.

Fruit peels of Banana, Pomegranate, Sweet lime and Orange are highly rich in potash, ion, Zinc etc. Above fruit peels powder were formulated from the trace amounts and gradually increased for the preparation of three formulations as Formulation 1, Formulation 2 and Formulation 3. Three different formulations were applied for plant growth in two methods such as fruit peel powder, fruit peel powd...

It is well known that Li-ion cells containing manganese oxide-based positive electrodes and graphite-based negative electrodes suffer accelerated capacity fade, which has been attributed to the deposition of dissolved manganese on the graphite electrodes during electrochemical cell cycling. However, the reasons for the accelerated capacity fade are still unclear. This stems, in part, from confl...
