Organic and Carbon Gels: From Laboratory Synthesis to Applications (Advances in Sol-Gel Derived Materials and Technologies)

by Ana Arenillas J. Angel Menéndez Gudrun Reichenauer Alain Celzard Vanessa Fierro Francisco José Maldonado Hodar Esther Bailόn-Garcia Nathalie Job

This expert volume provides specialized coverage of the current state of the art in carbon gels. Carbon gels represent a promising class of materials with high added value applications and many assets, like the ability to accurately tailor their structure, porosity, and surface composition and easily dope them with numerous species.

Organic Chemistry

by Marye Anne Fox James K. Whitesell

Organic Chemistry by Fox and Whitesell is the pioneer in the mechanistic approach. Now in its third volume, this classic and proven pedagogy provides a much better basis for students to retain a knowledge base and extend it to practical applications in other areas of science. The mechanistic approach groups chemical reactions according to how the sequence of changes occurs- their common mechanisms- rather than by functional groups (what category- alcohols, amines, alkenes, etc.). Where appropriate, the text subdivides information based on functional groups. The text covers ALL of basic organic chemistry in the first 14 chapters and reviews the reactions covered in these chapters in chapter 15 on multi-step synthesis. The text also contains extensive coverage of both industrial and biological polymers, and describes molecular basis for drug action.
