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 ...
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. ...
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...

The term ‘Corrosion’ means degradation of a material caused by chemical or electrochemical reaction with the environment. The material generally refers to metals but can also include non-metallic materials, such as ceramic, polymer and plastics. ...
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
Genetic identification of degraded DNA samples buried in different types of soil For this reason, this study aimed to analyse the degradation pattern of different mulch materials buried in two types of soils, clay and sand, under laboratory conditions (25掳C, dark surroundings, constant humidity)....
Corrosive materials are harmful to living things. If they fall on live tissue, they can cause irritation, burns, and scars. When a corrosive attack stones and metals, changes occur on their surfaces. Pitting, loss of luster, and slow degradation of the surface occurs. What is the simple ...
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 ...
