Using mills as efficient and ecologically friendly synthesis reactors
The term "green chemistry" is commonly used to describe chemical procedures which meet specific requirements with regards to the conservation of resources and protection of the environment. The objective is to avoid undesired by-products by selecting adequate reaction procedures and media. A ...
Catalysts are widely used as an important auxiliary material in the chemical and petrochemical industry. They are able to accelerate chemical reactions by lowering the activation energy, i.e. they change reaction kinetics. Thus, using catalysts in in
A number of factors influence the rheology of a suspension, including particle size, particle size distribution, and the volume fraction of solids present. Here we examine the relationship between rheology and particle size parameters. Commonly used
"Triple Detection" in Gel Permeation Chromatography
Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact th
1st July 2006 is an important deadline for the electro- and electronics industries. This date bans hazardous substances like lead, cadmium, mercury, hexavalent chromium and polybrominated biphenyls and diphenyl ethers from electro- and electronic equ
Using design of experiments methodology means increased efficiency and improved product quality.
Product quality in any arena can be traced back to variations in parts, materials, people, and processes. And since it has been observed that all work can be broken down into processes, all processes, manufacturing or administrative in nature, have inherent variability
What analyst does not wish for a universal method for processing all his or her samples? Pressure digestion represents just such a procedure for sample digestions and is therefore one of the standard sample preparation procedures currently employed i
Microwave-assisted organic synthesis (MAOS) has become an increasingly popular discipline in modern chemical method development. At first, reaction optimization and method development on a small scale were the main areas of interest in MAOS. However, the growing acceptance and success of this ...
