This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of 2-aryl-3-cyclohexyl-1,3-thiazolidine-4-one triphenyltin chloride complexes were synthesized by reacting 1,3-thiazolidine-4-ones with triphenyltin chloride in acetone. The compounds were characterized using IR, 1H NMR, 13C NMR and X-ray crystallography to determine their structures. Organic tin (IV) compounds are toxic, and their biological importance has been extensively studied most notably against Ceratocystis ulmi, the fungus that causes Dutch elm disease. It is important to understand both the structure and behavior of these tin (IV) compounds to understand their biological abilities. Hammett [sigma] plots were constructed for the complexed and uncomplexed 1,3-thiazolidine-4-one compounds to understand the behavior of the complexes in solution. While the analysis of the crystal structure of the solid triphenyltin complexes showed a trigonal bipyramidal geometry with the chloride and the 1,3-thiazolidine-4-one in axial positions, IR and NMR studies suggest facile dissociation of the 1,3-thiazolidine-4-one ligand in solution.

Download or read book Advances in Marine Antifouling Coatings and Technologies written by Claire Hellio and published by Elsevier. This book was released on 2009-05-22 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biofouling can be defined as the undesirable accumulation of microorganisms, algae and animals on structures submerged in seawater. From the dawn of navigation, marine biofouling has been a major problem for shipping in such areas as reduced speed, higher fuel consumption and increased corrosion. It also affects industries using off-shore structures such as oil and gas production and aquaculture. Growing concerns about the environmental impact of antifouling coatings has led to major new research to develop more environmentally-friendly alternatives. Advances in marine antifouling coatings and technologies summaries this wealth of research and its practical implications. This book is divided into four sub-sections which discuss: marine fouling organisms and their impact, testing and development of antifouling coatings, developments in chemically-active marine antifouling technologies, and new surface approaches to the control of marine biofouling. It provides an authoritative overview of the recent advances in understanding the biology of fouling organisms, the latest developments on antifouling screening techniques both in the field and in the laboratory, research on safer active compounds and the progress on nontoxic coatings with tailor-made surface properties. With its distinguished editors and international team of contributors, Advances in marine antifouling coatings and technologies is a standard reference for manufacturers of marine antifouling solutions, the shipping industry, oil and gas producers, aquaculture and other industries using offshore structures, and academics researching this important area. Assesses marine antifouling organisms and their impact, including a historical review and directions for future research Discusses developments in antifouling coatings examining chemically-active and new surface approaches Reviews the environmentally friendly alternative of safer active compounds and the progress of non-toxic compounds

Currently most texts in this area focus on either lithography with perhaps one or two chapters on resists, or on traditional resist materials with relatively little consideration of new approaches. This book therefore aims to bring together the worlds foremost resist development scientists from the various community to produce in one place a definitive description of the many approaches to lithography fabrication. Assembles up-to-date information from the world’s premier resist chemists and technique development lithographers on the properties and capabilities of the wide range of resist materials currently under investigation Includes information on processing and metrology techniques Brings together multiple approaches to litho pattern recording from academia and industry in one place

Download or read book The Power and Promise of Early Research written by Desmond H. Murray and published by ACS Symposium. This book was released on 2018-01-02 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Undergraduate research is a uniquely American invention. The ability to enter a laboratory and to embrace the unknown world, where a discovery is just around the corner, is a transformative experience. Undergraduate research, when done right, creates an authentic research project which changes the individual who is doing the research. Early introduction to authentic research captures student interest and encourages them to continue with their studies. The difficulty of undergraduate research is scale. To be truly authentic, and thus transformative, emerging scholars in the lab need to be guided by experts who clearly care for their junior collaborators. This apprenticeship model is time consuming, absolutely essential, and difficult to scale. To provide more authentic research experiences to students, dedicated teachers have developed the idea of course-based undergraduate research experiences (CUREs). This book offers a comprehensive overview of how authentic, early research is a strategy for student success. Dr. Desmond Murray and his co-authors demonstrate the importance of early introduction to authentic research for all students, including those that are most likely to be left out during the normal sink-or-swim research university science curriculum.
