Surfactants and Interfacial Phenomena

The greatest textual content at the houses and purposes of surfactants--now absolutely revised and up to date The previous decade has obvious major advancements in surfactant chemistry: the emergence of gemini surfactants, superwetting brokers, and eco-friendly surfactants. assurance in their constitution and purposes makes this new 3rd variation of Surfactants and Interfacial Phenomena, already the easiest on hand textual content at the topic, in particular well timed.

Preparative Chromatography. of Fine Chemicals and Pharmaceutical Agents

This interdisciplinary procedure combines the chemistry and engineering concerned to explain the notion and development of chromatographic techniques. The booklet covers contemporary advancements in preparative chromatographic techniques for the separation of "smaller" molecules utilizing usual laboratory gear in addition to the exact notion of commercial chemical crops.

The Engineering Of Chemical Reactions

Completely revised and up-to-date during this moment version, The Engineering of Chemical Reactions focuses explicitly on constructing the abilities essential to layout a chemical reactor for any software, together with chemical creation, fabrics processing, and environmental modeling. This version additionally good points new chapters on organic and environmental response engineering that supply an exhilarating creation to those more and more very important parts of modern-day chemical engineering marketplace.

Crystals in Glass: A Hidden Beauty

A "must-have" for fabrics engineers, chemists, physicists, and geologists, this can be one of many first "coffee-table" books within the box of glass technological know-how. Containing over fifty appealing micrographs, the e-book displays 35 years of unique examine through a very popular authority within the box. It comprises 50 slides culled from tens of millions of pictures on glass crystal nucleation, development, and crystallization.

These enzymes operated on the desacetyl acyclic free acid sophorolipid to remove the “outer” glucose, leaving a monosaccharide glycolipid in 80% yield. To the best of our knowledge, the only acyl groups that have been appended enzymatically to the sophorolipid carbohydrates are acetyl, acryloyl, methacryloyl, and succinoyl. It would be interesting to test how structurally variable is the set of acyl donors tolerated by the lipases in conjunction with the sophorose headgroup (more general studies on lipase utility have of course been performed).
