An object of uniform cross section will have a resistance proportional to its length and inversely proportional to its cross-sectional area, and proportional to the resistivity of the material. TCR is a fractional change in resistance per unit change in temperature at a specified temperature. In ...

Chemical hardness (η), first put forward by Pearson, is a measure of the resistance of a chemical species to change its electronic configuration53,54. According to the Hard and Soft Acid and Bases (HSAB) principle, a hard acid prefers a hard base and a soft acid prefers a soft base. ...

which can also improve toughness: chromium is added to confer resistance to high temperature oxidation and creep, as well as resistance to attack by hydrogen at high temperature and pressure (Chapter 10). In some cases boron is added to improve toughness at the same time as avoiding excessive ...
The device was allowed to cool down to room temperature and the edges were sealed with ultraviolet-curing resin (NOA 63). The water resistance of the metal-encapsulated photocathode was first confirmed by placing it in an aqueous buffer solution (0.1 M borate, pH 8.5) for several hours ...
the high R2resistance observed for TiO2/C and Ag/C would imply a slow hydrogen electrochemical adsorption, making the Volmer reaction the rate-determining step, as observed by Tafel diagrams (slope 0.16 V dec−1). However, when Ag was supported on TiO2, values of R2decreased drastically, ev...
The Al-Cu-Li alloys offer a high strength, high stiffness and resistance against fatigue fractures, in addition to a large reduction in weight (Rioja and Liu, 2012; Dursun and Soutis, 2014). The addition of 1 wt% Li to Al reduces the density of the alloy by 3% and increases the ...
