Once such products are isolated in their pure form, however, modern instrumental techniques can reveal structural details for amounts weighing as little as one-millionth of a gram. Synthesis of organic compounds Once the properties endowed upon a substance by specific structural units called ...
They cover a range of topics including industrially based problems, improving current experiments in the second year Analytical Chemistry unit, or developing new experiments for future cohorts in Inorganic/Analytical Chemistry units. The class is divided into groups of 3 students, with each group ...
compounds via C=C bond cleavage. Now the cleavage of alkenes to form carbon–nitrogen bonds—the aza version of ozonolysis, termed triazenolysis—has been developed. The reaction produces diamines from cyclic alkenes, while acyclic C=C bonds are broken to generate two separate amine units. ...
In the current work, ZSM-5 zeolite showing a dendritic 3D nanoarchitecture has been synthesized by the functionalization of protozeolitic nanounits with an amphiphilic organosilane, which provokes the branched aggregative growth of zeolite embryos. Dendritic ZSM-5 exhibits outstanding accessibility arising...
molecular biology, field of science concerned with studying the chemical structures and processes of biological phenomena that involve the basic units of life, molecules. The field of molecular biology is focused especially on nucleic acids (e.g., DNA and RNA) and proteins—macromolecules that are...

Boosting spontaneous orientation polarization of polar molecules based on fluoroalkyl and phthalimide units Polar organic molecules form spontaneous polarization in vacuum-deposited films originating from the molecule’s potential ability to align itself on the film surface during deposition. Here, the author...
(王祥科), and coworkers have successfully developed a covalent organic framework-based adsorbent containing “single-ion traps” for Pd(II) recovery from aqueous solutions. The adsorbent, which contains pyridine units, displays good stability, high adsorption ...
as a coupling unit in Scholl reactions and disclose that the C1 and C3 of 2-pyrenyl units are the favorable sites for the Scholl reaction while further coupling at C4 does not occur. Guided by these findings, they have successfully synthesized a double and sextuple helicene. This study opens...
Lossless integra-tion of capacitor units can be regarded as one of the efficient ways to achieve a wider voltage range, which has not yet been fully conquered due to the lack of rational designs of the electrode structure and integration technology. This study presents an alternatingly ...
