Degradation typeOutdoor exposureAccelerated aging testErosionCorrosionReflector materials for concentrating solar thermal (CST) technologies must preserve high quality properties (in terms of solar specular reflectance) over the complete lifetime of the solar system. However, these solar components are ...
Alloysare compounds consisting of more than one metal. Adding other metals can affect the density, strength, fracture toughness, plastic deformation, electrical conductivity and environmental degradation. 合金是由一种以上金属组成的混合物。加一些其它金属能影响密度、强度、断裂韧性、塑性变形、导电性以及环境...
15.2 Different generations of solar cell devices Based on active materials and power conversion efficiency (PCE), solar cells are classified into three different generations, namely, first, second, and third generation. First-generation solar cells are the most conventional type solar cells, made of...
speeds up the aging process by introducing sewage,detergents,fertilizers, and other nutrient sources into the ecosystem. Cultural eutrophication has had dramatic consequences on freshwater resources,fisheries, and recreational bodies of water and is one of the leading causes of aquatic ecosystemdegradation...
The distinction between carbon-chain and heterochain polymers is reflected in thetable, in which selected properties and applications of the most important carbon-chain and heterochain plastics are shown and from which links are provided directly to entries that describe these materials in greater deta...
These elements are not only the important sources of materials for building up the structures of plant tissues, but also are actively involved in the metabolic activities within plants7. For instance, Barlóg8 reported that magnesium and nitrogenous fertilizers were favorable for the growth, the 1...
The nuances of different capacitor types are, for the most part, determined by the characteristics of the dielectric used and the method by which a given device is constructed. All dielectric materials have limitations, with regard to the maximum applied field they can withstand for a given ...
This is also related to MPs changing microbial richness and diversity and enriching microbial communities involved in lignin compositions degradation. In the presence of MPs, soil DOM chemodiversity depended on soil pH, electrical conductivity, dissolved organic carbon, soil organic matter, bacterial ...
Adhesive, any substance that is capable of holding materials together in a functional manner by surface attachment that resists separation. “Adhesive” as a general term includes cement, mucilage, glue, and paste—terms that are often used interchangeab
heart (constant pressure and movement) or the bladder (adverse chemical presence) may require specialized or stronger materials to perform their role; usually such materials are either specially treated, or made of special polymers, and are often non-absorbable to reduce the risk of degradation. ...
