Liquid-metal embrittlement has a number of special characteristics. Not all solid metals are embrittled by all liquid-metal environments; rather, it only occurs for specific solid–liquid couples.Table IIIgives a number of examples. At low temperatures, the embrittlement does not occur because both...

plus the 365 nm near-UV line and a number of lines near 300 nm. The result is a high pressure mercury lamp that operates with an efficacy of about 55lmW−1and has a CRI of about 50. The high-mercury vapor pressurerequires a wall temperature of at least 360 °C, which in turn ...
In its pure form, mercury is an element -- symbol Hg on the periodic table, metallic, atomic number 80. It's a silvery substance that's liquid at room temperature, and it's naturally occurring. Some estimates put the amount of mercury emissions from natural activities, like volcanic eruptio...

(Latinized Greek: hydrargyrum, from "hydr-" meaning watery or runny and "argyros" meaning silver) and atomic number 80. A heavy, silvery d-block metal, mercury is one of five metallic chemical elements that are liquid at or near room temperature and pressure,[1][2] the others being ...
Deciding to clean every number and letter contact in my Seeburg with alcohol and a cotton swab – by hand no less – is not at all within my character, but having let a jukebox tab slip between the speakers and turntable track basically necessitated the surgery, and ultimate sense of respo...
Packing defects may also occur at the point of contact between the nucleus and the substrate. Dislocations arise due to the plastic deformation of the grown film. Electron micrograph analysis suggests that the dislocation structure of the films is closely related to the presence of elastic ...
Biopsies of positive chlorpromazine photoallergic reaction sites showed a histopathologic picture consistent with that of delayed-type hypersensitivity; that is, reactions similar to those of classical experimental allergic contact dermatitis in humans. Over the ensuing years, a considerable number of ...
