Book Description
Faceting of high angle grain boundaries in SIGMA = 3 and SIGMA = 5 coincidence lattices of the fcc structure was studied using thinfilm bicrystal specimens of controlled geometry. A number of relatively high index boundaries in the coincidence lattices (containing relatively low planar densities of coincidence sites) was found to break up into low energy facets corresponding to low index planes of the coincidence lattices (containing high densities of coincidence lattice sites). These results are consistent with a general expectation that the grain boundary energy decreases as the planar density of coincidence sites increases, i.e., the two-dimensional periodicity of the boundary becomes shorter, and long-ranged distortions are reduced.

The Challenge Posed by New Synthetic Opioids: Pharmacology and Toxicology
Author: Simona Pichini
Publisher: Frontiers Media SA
ISBN: 2889459721
Category :
Languages : en
Pages : 107
Book Description
New Synthetic Opioids (NSOs), most of which are illegally produced and sold for recreational use, are posing a serious threat to the health of consumers. Due to the low cost of materials and equipment required for clandestine laboratories production with respect to the production cost of heroin, NSOs are climbing the illegal street and web drug market. Several of these drugs have been involved in a recent rise in acute intoxications and overdose deaths. Since NSOs offer enormous profit potential, and there is strong demand for their use, these drugs are being trafficked by organized crime and present major challenges for medical professionals facing intoxications and fatalities, law enforcement agencies fighting against their diffusion and policymakers trying to restrain the use and abuse of NSOs. This Research Topic aimed to fill the gap on current knowledge on pharmacology and toxicology, health risks for adult and newborns of NSOs covering both basic scientific as well as epidemiological and clinical aspects. 3 reviews, 3 mini-reviews, 1 original article, 2 case reports and 1 opinion are here presented.

High-Energy Spectroscopic Astrophysics
Author: Steven M. Kahn
Publisher: Springer
ISBN: 3540270132
Category : Science
Languages : en
Pages : 306
Book Description
After three decades of intense research in X-ray and gamma-ray astronomy, the time was ripe to summarize basic knowledge on X-ray and gamma-ray spectroscopy for interested students and researchers ready to become involved in new high-energy missions. This volume exposes both the scientific basics and modern methods of high-energy spectroscopic astrophysics. The emphasis is on physical principles and observing methods rather than a discussion of particular classes of high-energy objects, but many examples and new results are included in the three chapters as well.

Infrared Fiber Optics
Author: Jas Sanghera
Publisher: CRC Press
ISBN: 9780849324895
Category : Science
Languages : en
Pages : 368
Book Description
In the past 10 years, there have been many developments in the field of infrared transmitting fiber optics. This is highlighted by the many different fiber compositions that have been studied around the world for numerous practical applications. This book reviews different fiber systems, describing material properties, techniques used to prepare the fibers and fiber properties with particular emphasis on optical properties. These fibers possess unique optical, mechanical, and physical properties, enabling many technologies. Examples of applications are described within given chapters, allowing an engineer or scientist to choose the most appropriate fiber for a desired application. The introduction gives the reader an overview of transmission theory so that the basic concepts are clearly understood by someone new to the field. The next several chapters describe the different types of infrared transmitting fibers, including glass fibers such as those based on silica, fluoride, and chalcogenide glasses; the crystalline fibers based on single or polycrystalline materials; and hollow waveguides. The commercial chemical sensing applications of some of these new fibers are described. The final chapter summarizes the properties of the fibers and highlights future prospects.
