Enjoy this great book!   
The aim of this book is to survey a number of chemical compounds that some chemists, theoretical and experimental, find fascinating. Some of these compounds, like planar carbon species or oxirene, offer no obvious practical applications; nitrogen oligomers and polymers, in contrast, have been touted as possible high-energy-density materials.</description><link>http://ebook30.com/science/chemistry/151754/modeling-marvels-computational-anticipation-of-novel-molecules.html</link><guid>http://ebook30.com/science/chemistry/151754/modeling-marvels-computational-anticipation-of-novel-molecules.html</guid><author>Ebook30.com</author></item><item><title>Schaum's Outline of Organic Chemistry</title><pubDate>Thu, 19 Nov 2009 15:45:02 +0100</pubDate><category>Chemistry</category><description>&lt;div&gt;&lt;a href="http://ebook30.com/science/chemistry/151720/schaums-outline-of-organic-chemistry.html"&gt;&lt;img width="200" src="http://image.ebook30.com/data_images/2009/11/19/1258634518-0010ba9amedium.jpeg"/&gt;&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;Mg-H | 1999 | ISBN: 007134165X | 464 pages | Djvu | 5,8 MB

With such a wide diversity of properties and applications, is it any wonder that industry and academia have such a fascination with polymers? A solid introduction to such an enormous and important field is critical to the modern polymer scientist-to-be, but most of the available books do not stress practical problem solving or include recent advances.</description><link>http://ebook30.com/science/chemistry/151106/introduction-to-polymer-science-and-chemistry-a-problem-solving-approach.html</link><guid>http://ebook30.com/science/chemistry/151106/introduction-to-polymer-science-and-chemistry-a-problem-solving-approach.html</guid><author>Ebook30.com</author></item><item><title>Physical Chemistry, Third Edition</title><pubDate>Tue, 17 Nov 2009 16:09:05 +0100</pubDate><category>Chemistry</category><description>&lt;div&gt;&lt;a href="http://ebook30.com/science/chemistry/151105/physical-chemistry-third-edition.html"&gt;&lt;img width="200" src="http://image.ebook30.com/data_images/2009/11/17/1258463152-0010b190medium.jpeg"/&gt;&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;Robert G.

Most of the measurements and calculations in chemistry are concerned with quantities such as pressure, volume, mass, and energy. Every quantity includes both a number and a unit. The unit simultaneously identifies the kind of dimension and the magnitude of the reference quantity used as a basis for comparison. The number indicates how many of the reference units are contained in the quantity being measured.</description><link>http://ebook30.com/science/chemistry/150943/schaums-easy-outlines-college-chemistry.html</link><guid>http://ebook30.com/science/chemistry/150943/schaums-easy-outlines-college-chemistry.html</guid><author>Ebook30.com</author></item><item><title>Food Safety: A Reference Handbook</title><pubDate>Mon, 16 Nov 2009 14:30:02 +0100</pubDate><category>Chemistry</category><description>&lt;div&gt;&lt;a href="http://ebook30.com/science/chemistry/150820/food-safety-a-reference-handbook.html"&gt;&lt;img width="200" src="http://image.ebook30.com/data_images/2009/11/16/1258370820-0010acecmedium.jpeg"/&gt;&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;ABC-CLIO | 2007 | ISBN: 1598840495 | 331 pages | PDF | 1,1 MB 

Salmonella, mad cow disease, pesticides-just how safe is the food we eat? This book is packed with information about current and historical issues in food safety. The laws, the facts, and figures are backed up with real-life events: Upton Sinclair's 1906 expose of the meat packing industry, The Jungle, led to the Beef Inspection Bill, but 90 years later 732 people were poisoned and 4 children died after they ate tainted beef.</description><link>http://ebook30.com/science/chemistry/150820/food-safety-a-reference-handbook.html</link><guid>http://ebook30.com/science/chemistry/150820/food-safety-a-reference-handbook.html</guid><author>Ebook30.com</author></item><item><title>Advanced Organic Synthesis</title><pubDate>Mon, 16 Nov 2009 00:45:02 +0100</pubDate><category>Chemistry</category><description>&lt;div&gt;&lt;a href="http://ebook30.com/science/chemistry/150686/advanced-organic-synthesis.html"&gt;&lt;img width="200" src="http://image.ebook30.com/data_images/2009/11/15/1258321316-0010aad3medium.jpeg"/&gt;&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;Publisher: Academic Press Inc | ISBN: 0125049501 | edition 1971 | PDF | 209 pages | 10,14 mb

The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. More than 285 volumes have been published (all of them still in print) and much of the material is relevant even today--truly an essential publication for researchers in all fields of life sciences.</description><link>http://ebook30.com/science/chemistry/149846/methods-in-enzymology-volume-290-molecular-chaparones-john-n.-abelson-melvin-i.-simon-george-h.-lorimer-thomas-o.-baldwin.html</link><guid>http://ebook30.com/science/chemistry/149846/methods-in-enzymology-volume-290-molecular-chaparones-john-n.-abelson-melvin-i.-simon-george-h.-lorimer-thomas-o.-baldwin.html</guid><author>Ebook30.com</author></item><item><title>Organic Chemistry</title><pubDate>Thu, 12 Nov 2009 16:21:01 +0100</pubDate><category>Chemistry</category><description>&lt;div&gt;&lt;a href="http://ebook30.com/science/chemistry/149755/organic-chemistry.html"&gt;&lt;img width="200" src="http://image.ebook30.com/data_images/2009/11/12/1258031870-00109cf0medium.jpeg"/&gt;&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;Publisher: Thomson Brooks/Cole | ISBN: 0534373666 | edition 1999 | DJVU | 1338 pages | 13,57 mb

Widely and consistently praised as the most clearly written book on the market. Why? In John McMurry's words: "I have been asked hundreds of times over the past ten years why I wrote this book. I wrote this book because I love writing.
