For every chemical compound that has caused societal, environmental or health issues (asbestos, DDT, thalidomide, chlorofluorocarbons), there are dozens of others which have caused no harm or provided us with great benefits (penicillin, Kevlar, Nylon).Safety Emporium has all kinds of lab equipment...
The chemical sensors bind specific target chemicals through sorption-desorption processes by using selective interfaces, which result in the generation of a signal through the transducer and electronic circuitry [32]. Though, it is hard to achieve 100%selectivityfor a specific chemical compound due to...
Each Twitter account has a profile picture; for an organization this is usually a logo, but for personal accounts most people use a headshot. This literally puts a face to the account and makes it more human — others will know who they are interacting with and it can be helpful for reco...
Through chemical analysis of the whisky samples and automated compound detection, we report over 200 mostly aroma-active volatiles. To test both approaches for their potential for sample classification, a simple classification problem (Scotch vs. American) was applied. Linear discriminant analysis (LDA...
A telluride is a compound of the element tellurium and one or more other elements. For example, the mineral calavarite is mostly gold telluride (AuTe 2 ). At one time, gold was found in chunks or nuggets large enough to see. People mined gold by picking it out of streams and rivers...
Basic Concepts of Rubber What is "rubber?" What is a rubber compound? Why does rubber act "rubbery?" How is rubber made? What is vulcanization? What is compression set? What is the difference between a thermoset and thermoplastic?
To obviate constipation, ten or fifteen grains of the compound rhubarb pill were used; but where there was much derangement of the biliary functions, brisk purging was resorted to immediately after the cessation o... Snow,J. - 《Lond J Med》 被引量: 2发表: 0年 Pie and Whiskey She's ...
Spirit drinks have a complex chemistry and especially those, such as Scotch whisky for example, that undergo maturation in wooden casks. The major chemical compound of importance is of course ethanol, which has also been at the forefront of many previous studies as the target of detection and ...
Ethyl alcohol is used for many of the same purposes. It is also the alcohol found in beer, wine, and hard liquor, such as whiskey and vodka. All alcohols are poisonous but some alcohols are more poisonous than others. If not drunk in moderation, alcoholic beverages can damage the body ...
