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...
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...
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
The performance of organic solar cells (OSCs) has increased substantially over the past 10 years, owing to the development of various high-performance organic electron–acceptor and electron–donor materials, including polymers, small molecules and fulle

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...
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 ...
In particular, from an application of the model to decalcified cement pastes, it is shown that that the decalcification of the C-S-H phase is the primary source of the macroscopic elastic modulus degradation, that dominates over the effect of the dissolution of Portlandite in cement-based ...
This article includes part of the research carried out within the project 'Complex techniques of investigation, evaluation, conservation and restoration of collagenic ethnographic materials', financed by the National Centre of Management Programs. The main causes of deterioration, factors in degradation ...
