  • In offering this book to teachers of elementary chemistry the authors lay no claim to any great originality. It has been their aim to prepare a text-book constructed along lines which have become recognized as best suited to an elementary treatment of the subject. At the same time they have made a consistent effort to make the text clear in outline, simple in style and language, conservatively modern in point of view, and thoroughly teachable.

  • THE publication of this series of pamphlets has been undertaken to make available in a permanent form complete detailed directions for the preparation of various organic chemical reagents. In announcing this purpose it may be well to mention at the outset some of the difficulties in the way of the research chemist, which it is hoped this series will be able to overcome. The cost of chemicals is prohibitive to the majority of chemists; this was true before the war when Kahlbaum's

  • Congratulations. You have just purchased the most complete and informative book on recreational drug manufacture available. It is based upon a great deal of experience and a tremendous amount of research. I have used easy to understand terms to aid in comprehension of the formulas given and in the theory involved. I have patterned this book after what would appear to be a college textbook or a college accredited correspondence course in illicit drug manufacturing. Please follow carefully my instructions and advice on safety, purification, and referred to reading....

  • Science seeks to understand and explain our world, be that its physical composition (geology), chemical composition (chemistry), the way its composite matter interacts (physics), or the organisms that inhabit it (biology). We can only get an idea of what life is all about by piecing together information from each discipline to give us the big picture. We don’t have to look very far to realize that it is difficult, if not impossible, to separate biology from chemistry. After all, our body is a bag of chemicals.

  • Performing experiments in low Earth orbit has been the focus of much of the research funded by NASA’s Physical Sciences Division (PSD) and its predecessors for over 30 years. This microgravity research can be divided into five broad areas, all of which focus primarily on phenomena that are strongly perturbed by gravity: biotechnology, combustion, fluid physics, fundamental physics, and materials science.

  • Chemistry is the science which treats of the intra-atomic or the intra-molecular changes which material things undergo under various influences. Mental is defined as “of or appertaining to the mind, including intellect, feeling, and will, or the entire rational nature.” Science is knowledge gained and verified by exact observation and correct thinking. Mental chemistry is, therefore, the science which treats of the changes which material conditions undergo through the operations of the mind, verified by exact observation and correct thinking.

  • The prototypical catalytic reductiveC–Cbond formations, the Fischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homogeneous metal catalysis, accounting for the production of over 7 million metric tons of aldehyde annually.

  • This edition is a reprint of the first in response to a continuous demand for the book. The matter, consisting as it does largely of records, does not call for any revision, and, as a contribution to the development of theory, any particular interest which it has is associated with the date at which it was written. The volume which has since appeared is the sequel, and aims at an exposition of the subject "to date".

  • Physics has an important role in our life. Without physics and the work of physicists, our modern life would not exist. Using physics, people created machines, instruments and some different divices from the crudest to the most modern aspect. Techology is developed more rapidly, more modern day by day. Moreover, all other natural sciences- example chemistry, biology, medicinedepend upon physics for the foundations of their knowledge.

  • The Chemical Sciences Roundtable (CSR) was established in 1997 by the National Research Council. It provides a science-oriented apolitical forum for leaders in the chemical sciences to discuss chemistry-related issues affecting government, industry, and universi- ties. Organized by the National Research Council’s Board on Chemical Sciences and Technology, the CSR aims to strengthen the chemical sciences by fostering communication among the people and organizations—spanning industry, government, universities, and professional associations—involved with the chemical enterprise.
