Why is leather a mixture, and not a pure substance? Why do we use tungsten, which is a metal having low resistivity to make the filament of a bulb, rather than using an alloy having high resistivity and high me
The crystalline substance found in most disposable diapers is sodium polyacrylate, a chemical absorbent used in the super absorbent layer. Sodium polyacrylate can absorb 200 to 300 times its weight in tap water, transforming it into a gooey gel to keep the diaper surface dry. While sodium polyacr...
All that is needed to make basic steel is a combination of iron and carbon. However, over time it was found that adding different elements to this basic steel substance can increase its toughness or hardness. These added elements account for what is the major difference of most types of stee...
The site has three main habitats along a permafrost thaw gradient, with distinct vegetation and thaw status: (1) palsa, overlaying permafrost, well-drained and dominated by woody plants and shrubs; (2) bog, intermediate thaw with variable water table depth characterized by a mixture of woody,...

the electrolyte, a substance that allows lithium ions to move between the battery's electrodes, also known as its anode and cathode. This barrier also serves to separate the electrodes and can be used to shut down the battery if it becomes too hot, for example, during charging or ...
Removing the applied electric field allows the electrons in the dielectric to return to their normal distribution around the nuclei to which they’re attached, or the molecules in the substance to return to their original random orientation or shape. In the process of so doing, most of the ...
