Aerogels are the lightest solids known. Up to 1000 times lighter than glass and with a density as low as only four times that of air, they show very high thermal, electrical and acoustic insulation values and hold many entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal and ceramic materials, etc. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum d...
Flavor science is continually evolving. Remaining current with the latest research and establishing a broad and sound understanding of the major developments and breakthroughs can be a challenge. The Weurman Flavour Research Symposium has long been regarded as the premier professional meeting focused on the science of flavor. Flavour Science, an extensive review of the most recent symposium, presents the latest in flavor research, enriching the chemistry-based vision of most flavorists and flavor chemists with understanding from a broad range of fields, including human physiology, ethology, psychophysics, genetics, bioinformatics or metabolomics. This book is ideal for all flavor scientists, food chemists and sensory scientists and has a strong audience among enologists as well. - Focuses on the rapidly changing field of flavor science - Includes the latest information on the physiology, chemistry and measurement of flavor - Presents practical information on the flavor industry and emerging trends
An uplifting study of the scientific evidence for the afterlife from an experienced anesthesiologist/intensive care physician • Details meticulously recorded and hospital-verified cases of near-death experiences • Cites scientific research on NDEs to refute the standard objections of doubters and materialists point by point • Explores out-of-body experiences, sessions with mediums, electronic communication with the deceased, and other signs from the afterlife Over the course of his 25-year career as an anesthesiologist and intensive care physician, Jean Jacques Charbonier, M.D., gathered hundreds of accounts of patients who returned from clinical death. Across all of these accounts--fr...

In wine, more than 800 volatiles have been identified and most of them are present at lower or similar levels to their individual perception thresholds. However, recent evidence establishes the significance of low impact odorants in global odor perception. Using the high pressure liquid chromatography (HPLC) method we developed a methodology to prepare aromatic reconstitutions from wine extract fractions instead of pure compounds. The existence of particular perceptive interactions in the expression of fruity aroma was demonstrated. Concerning fresh fruit aroma, an additive effect was observed due to fractions with low fruity note and a masking effect was perceived due to fractions with caramel and lactic aroma.
This book provides the reader with a clear overview of the considerable body of research and development work carried out in the last five years on microstructured polymer optical fibres (mPOFs). It discusses new applications which will be opened up by this emerging technology and includes for the first time details about the fabrication process for these fibres. The book provides an excellent introduction to this new technology.
This clear and concise book is the first to address the hot topic of functional silica gels and their applications.
As an applied science, Enology is a collection of knowledge from the fundamental sciences including chemistry, biochemistry, microbiology, bioengineering, psychophysics, cognitive psychology, etc., and nourished by empirical observations. The approach used in the Handbook of Enology is thus the same. It aims to provide practitioners, winemakers, technicians and enology students with foundational knowledge and the most recent research results. This knowledge can be used to contribute to a better definition of the quality of grapes and wine, a greater understanding of chemical and microbiological parameters, with the aim of ensuring satisfactory fermentations and predicting the evolution of wi...
Once considered a bastion of learning, leadership, and disciplined lifestyle, today’s private military academies are often regarded as expensive holding facilities for unwanted, incorrigible boys who have nowhere else to go. Their depiction in popular media has reinforced the impression that they are boot camps disguised as educational institutions. The reality is far more complex and far more encouraging. Using a decade of participant observation research, including serving as an instructor at some of these schools, anthropologist William Trousdale explores the contemporary experience of military school life. From the admissions office to daily life in barracks, classrooms, playing fields, and social events, he describes how these schools endeavor to realize their mission of creating educated, mature young men from largely at-risk youth and the challenges—both met and unmet—in doing so. This volume will be of interest to those studying secondary and alternative education, at-risk youth, and the role of the military in society.
