The average metal–metal overlap population is almost constant and maximum in the VEC range 44–50, which corresponds exactly to the VEC range of the characterized compounds. Related phases deriving from the Ti5Te4 structure through insertion of extra metal atoms or metal clusters between the ...

Bundle: Atoms and the Periodic Table This bundle is a $106.00 value, but has been marked down by 20%! A great deal, so don't miss out!This digital package contains everything that I have personally made and incorporate into the current science curriculum about Elements, Compounds, and The...
TOO SMALL: Compounds and chemical equations involve simple numbers of atoms; unfortunately, atoms are too small to count. For example, to make table salt (sodium chloride, NaCl), we simply need one sodium atom to combine with one chlorine atom. It sounds easy, but these atoms are too ...
chemistry. We highlight the potential of innovative computational tools in processing structurally complex natural products to predict their macromolecular targets and attempt to forecast the role that natural-product-derived fragments and fragment-like natural products will play in next-generation drug ...
There are two identical asymmetric carbon atoms in the tartaric acid molecule, which is a by-product of the wine industry. Due to its low price, it is often used to resolve other racemates, such as epinephrine and chloramphenicol... - 《Journal of the Electrochemical Society》 被引量: 0发...
This method is of value when the counting of individual carbon atoms of the glucose molecule is not desired. The decline of blood glucose specific activity has been determined in a normal subject.关键词: chemistry analytical procedures blood carbon 14 gluconic acid glucose labelled compounds liquids...
ahow is the valence shell of hydrogen in hydrogen compounds different from the valence shell of other atoms when they form bonds 正在翻译,请等待... [translate] aBut it is also true that many childen today are using computers at schools before they can write 正在翻译,请等待... ...
Our current understanding of the metabolism of endogenous and xenobiotic compounds has come in the main from the use of molecules labelled with radioisotopes. The compound under investigation is synthesised so that selected atoms in the molecule are enriched with the desired radioisotope. The resulting...
Weak metal-metal bonds in an \"electron-rich\" cluster. The synthesis and x-ray crystallographic characterization of Os4(CO)12(.mu.3-S)2 and Os6(CO)16(.mu.4-S)(.mu.3-S) 4 contains a butterfly cluster of four osmium atoms with sulfido ligands bridging the two open triangular faces...
