variety of chemical substances. Fine Ceramics (also known as “advanced ceramics”) possess a high degree of chemical resistance to acids and alkalis. The artificial joints shown below are made of materials that are compatible with the internal chemistry of the human body. 人体包含各种各样的化学...
Since the original writing of The Psychological Basis of Perfumery , new information has been generated about the chemical nature and semiochemical properties of human body odors. This has been made possible by dramatic improvements in chemical isolation and analysis techniques which have lowered the ...
e.g. If the supply of vitamins and minerals in the diet is inadequate, this will result in changes in body chemistry. 如果饮食中的维生素和矿物质含量太低,将会引起人体化学结构的变化。 3.(互相之间的)吸引,亲密 If you say that there is chemistry between two people, you mean that is obvious...
While there is information on the chemistry of the vitreous body (VB) in various animals,1-12,14,15,24-29,31 reports on chemical constituents of the human VB are virtually nonexistent except for a few data on enucleated eyes.3,16 Since material from human eyes during life is not availabl...
Food is the main source of Cd in the human body, so various technologies for removing Cd from food have been studied. These technologies are based on the binding mechanism between Cd and proteins. In this work, the enrichment of Cd and the harm of Cd are described. And the binding ...
The enzymatic conversion of NH4+ and NO2– to N2 catalysed by bacteria is critical to maintain nitrogen balance in the environment and for wastewater treatment. Now, a simple abiotic catalyst, the naturally occurring mineral, covellite, shows a remarkable mimicry for the entire reaction pathway. ...
The nanoparticles have better activity as result of having a wider surface area compared to the same material in a larger form [1]. The nanoparticles can be engineered in various sizes and shapes and can be used for the advancement of biotechnology [2,3]. Currently researchs are not only ...
