Due to their unique porous properties, zeolites (also referred to as molecular sieves) are used in a variety of applications - major uses are in petrochemical cracking, ion-exchange (water softening and purification), and in the separation and removal of gases and solvents. Molecular Sieves: From Basic Research to Industrial Applications, Volume 158 A,B presents over 265 worldwide contributions on the latest developments in zeolitic research. Readers will find this book, which is divided into five sections: Synthesis, Characterization, Adsorption, Catalysis, and Novel applications, ideal for staying up to date on current research on porous materials.* Comprehensive overview of current research on porous materials* Contains experimental as well as theoretical input, reflecting the increasing overlap between theory and experiment* Contributions from the world's leading authorities

From areport by a Lieutenant Colonel W.A. Ross (Chern. News, Nov.15, 1878, p. 236). Progress did not accelerate during the next 50 years. McBain, in his clas sic 1932 book, The Sorption oi Gases by So lids, devoted a chapter to sorp tion by chabasite, other zeolites, and permeable crystals. McBain remarked that "great interest attaches to the finding of Weigel and Steinhoff [0. Weigel and E. Steinhoff, Z. Kris!., 61, 125 (1925{raquo}) that chabasite rapidly sorbs the vapors of water, methyl and ethyl alcohol and formie acid, whereas acetone, ether and benzene are largely excluded. The significance of their results was pointed out by McBain [J.W. McBain, Colloid. Syrnp. Mon., 20, 1 (1926{raquo}) and recognized by alliater writers. It is evident that the partially dehydrated chabasite forms a nearly perfect molecular sieve or a semipermeable membrane of extremely regular structure ... ". While the significance of the above observation may have been recog nized, it had little impact. Thus, an eminent pioneer in the synthesis and characterization af zeolites, Professor R.M. Barrer, spent nearly two dec ades (following his Ph. D. studies in the 1930s) developing a firm foundation for the rapid growth in scientific understanding and industrial applications of zeolites which has taken place during the last 30 years.

The helpful advice, prayers, and devotions included in this manual aid anyone who finds himself serving the church and helping others in those tough situations when “you don’t know what to say.” Pastoral care in the church is not limited to pastors and other designated church leaders. Many parishioners perform services in the name of the church, and this book is a great guide for them. It includes helpful advice and tips on visiting the suffering, devotional aspects surrounding pastoral visits, prayers for any situation, and helpful Scripture passages. Designed to be portable, this manual is an invaluable resource for those who care for others.

Introduction to Zeolite Molecular Sieves, 3rd Edition presents a collection of the most important results and ideas in the field of molecular sieve chemistry and technology, the most important experimental techniques related to the research activities in molecular sieves, and identifies new areas of molecular sieve chemistry. Chapters start at a reasonably simple entry level, but also covers the present state-of-the-art in the field. Topics covered include structure, synthesis, characterization, ion exchange, adsorption, diffusion, separations, and natural zeolites.* 6 years since the last edtion this book brings together the rapid development within the field of molecular sieve chemistry and applications * Accessible to newcomers to the field, also containing valuable information for experienced researchers * 27 chapters written by renowned scientists in their field, including updates on some 2nd edition chapters

Purification of Laboratory Chemicals, Eighth Edition, tabulates methods taken from literature for purifying thousands of individual commercially available chemicals. To help in applying this information, the more common processes currently used for purification in chemical laboratories and new methods are discussed. For dealing with substances not separately listed, a chapter is included setting out the usual methods for purifying specific classes of compounds. - Features empirical formulae inserted for every entry - References all important applications of each substance - Updates and confirms the accuracy of all CAS registry numbers, molecular weights, original reference, and physical data - Provides increased coverage of the latest commercial chemical products, including pharmaceutical chemicals, updated safety and hazard material, and expanded coverage of laboratory and work practices and purification methods
