Enjoyment

Off-lattice models enjoy a growing popularity. Again, a particle corresponds to a small number of atomistic repeat units... 

In solid state materials, single-step electron transport between dopant species is well known. For example, electron-hole recombination accounts for luminescence in some materials [H]. Multistep hopping is also well known. Models for single and multistep transport are enjoying renewed interest in tlie context of DNA electron transfer [12, 13, 14 and 15]. Indeed, tliere are strong links between tire ET literature and tire literature of hopping conductivity in polymers [16]. 

My wife still teases me on occasion that I was always a stellar student (she uses the more contemporary expression nerd ) and school valedictorian. Stndying, however, always came easy for me, and I enjoyed it. I was (and still am) an avid reader. In my formative school years I particularly enjoyed the classics, literature, and history, as well as, later on, philosophy. I believe obtaining a good general liberal... 

To be able to prepare and study these elusive species in stable form, acids billions of times stronger than concentrated sulfuric acid were needed (so called superacids). Some substituted carbocations, however, are remarkably stable and are even present in nature. You may be surprised to learn that the fine red wine we drank tonight contained carbocations which are responsible for the red color of this natural 12% or so alcoholic solution. I hope you enjoyed it as much as I did. 

Chemistry does not always enjoy the best of reputations. Many of our plants and refineries are still potentially dangerous and may pollute their surroundings. At the same time our society enjoys a high standard of living not in small measure through the results of chemistry, which few would give up. I believe that chemistry can and will be able to bring about an equilibrium between mankind s needs and our environmental concerns. Chemistry will continue to benefit mankind in the spirit of Alfred Nobel, a fellow chemist whose example continues to inspire us all. 

In an increasingly technological society, the world s per capita resources have difficulty keeping up. Society s demands, however, must be satisfied while at the same time safeguarding the environment to allow future generations to continue to enjoy planet Earth as a hospitable home. Establishing an equilibrium between mankind s needs and the environment is a challenge we must meet. 

Another way in which academic chemists keep in touch with industry is through consulting. During the years I consulted at different times for Exxon, Chevron, Cyanamid, ENICHEM (Italy), and Pechiney-Kuhlman (Erance, when a friend, Lucien Sobel, was a research director). I enjoyed these contacts, because they kept me aware of current industrial developments and interests. At the same time, it was also rewarding to be able to suggest to my industrial friends new approaches and directions that on occasion were useful and resulted in practical applications. 

Plus, this edition of Total Synthesis marks the first ever collaboration of the chemical underground. Throughout the book you will find recipes, secrets and discussions contributed by the worlds leading underground chemists. They have shared their knowledge so that you may get the best education available. So enjoy ...

Langmuir referred to the possibility that the evaporation-condensation mechanism could also apply to second and higher molecular layers, but the equation he derived for the isotherm was complex and has been little used. By adopting the Langmuir mechanism but introducing a number of simplifying assumptions Brunauer, Emmett and Teller in 1938 were able to arrive at their well known equation for multilayer adsorption, which has enjoyed widespread use ever since. 

Benzene has enjoyed some popularity as an adsorbate for surface area determination over a number of years. It can be used conveniently at temperatures around ambient, but assignment of a value to its molecular...
