A metal-oxygen battery (sometimes referred to as a ‘metal-air’ battery) is a cell chemistry in which one of the reactants is gaseous oxygen, O2. Oxygen enters the cell typically in the positive electrode—perhaps after being separated from an inflow of air—and dissolves in the electrolyte. The negative electrode is typically a metal monolith or foil. Upon discharge, metal cations present in the ...

Introduction: In recent years, the use of neutrons has increased in various fields such as medicine and industry. One of the important applications of neutrons is in medical research. Neutrons have greater linear energy transfer than gamma rays and are considered more dangerous radiation. Hence, the detection and determination of neutron dose is a very important and vital issu...

<span lang="EN-US">Lithium ion batteries have been widely applied in portable electronic devices and electric vehicles as high-density energy storage. The significant consumption of lithium is outweighed by the threat to environment battery waste. Recovery valuable metals contained batteries, such Cu foil, one efforts overcome environmental pollution due copper metal. hydrometallurgical m...

the aim of the present study was to examine anthropometric characteristics and selected physical fitness factors in male elite athletes (epee, foil, sabre) of iran national fencing team. the statistical population consisted of 30 athletes of fencing national team (age range 22.2± 3.67 yr) in the three weapons (epee n=10, foil n=10 and sabre n=10). anthropometric characteristics (sitting height,...

Abstract This study utilizes a hot water treatment (HWT) method for introducing antibacterial properties to aluminum (Al) surfaces, which has relevance in several industries ranging from food packaging and ventilation systems biomedical materials. The HWT process can produce nanostructured oxide layer on wide range of metallic materials by simply immersing the metal at temperatures 75 °C 95 °C....

Iron and chromium based alloys have found wide application in various fields of science technology. A primary carrier on Fe-Cr-Al alloy is used block catalysts for high-temperature hydrocarbon conversion, production metal neutralization toxic gases released during operation internal combustion engines, as well those present smoke emissions from enterprises. The influence thermal action foil sta...

The fluid dynamics of many swimming and flying animals involves the generation and shedding of vortices into the wake. Here we studied the dynamics of similar vortices shed by a simple two-dimensional flapping foil in a soap-film tunnel. The flapping foil models an animal wing, fin or tail in forward locomotion. The vortical flow induced by the foil is correlated to (the resulting) thickness va...

‘THEUSE of heavy aluminum foil in our ashing procedure for PB1 (1), introduced 3 years ago, has proved extremely successful in preventing cross-contamination. A Temco double-door muffle furnace is used for which three steel buckets were made; small buckets, 4 in. wide, 6 in. long, and 6 in. deep, and one large bucket, 6 in. wide, 8 in. long, and 6 in. deep. A steel shovel was made to aid the te...
