In recent interactions with industrial companies it became quite obvious, that the search for new materials with strong anisotropic properties are of paramount importance for the development of new advanced electronic and magnetic devices. The questions concerning the tailoring of materials with large anisotropic electrical and thermal conductivity were asked over and over again. It became also quite clear that the chance to answer these questions and to find new materials which have these desired properties would demand close collaborations between scientists from different fields. Modem techniques ofcontrolled materials synthesis and advances in measurement and modeling have made clear tha...
This proceeding constitutes the thoroughly refereed proceedings of the 1st International Conference on Combinatorial and Optimization, ICCAP 2021, December 7-8, 2021. This event was organized by the group of Professors in Chennai. The Conference aims to provide the opportunities for informal conversations, have proven to be of great interest to other scientists and analysts employing these mathematical sciences in their professional work in business, industry, and government. The Conference continues to promote better understanding of the roles of modern applied mathematics, combinatorics, and computer science to acquaint the investigator in each of these areas with the various techniques and algorithms which are available to assist in his or her research. We selected 257 papers were carefully reviewed and selected from 741 submissions. The presentations covered multiple research fields like Computer Science, Artificial Intelligence, internet technology, smart health care etc., brought the discussion on how to shape optimization methods around human and social needs.
Since the introduction of FT-NMR spectroscopy around five decades ago, NMR has achieved significant advances in hardware and methodologies, accompanied with the enhancement of spectral resolution and signal sensitivity. Rapid developments in the polymers field mean that accurate and quantitative characterization of polymer structures and dynamics is the keystone for precisely regulating and controlling the physical and chemical properties of the polymer. This book specifically focuses on NMR investigation of complex polymers for the polymer community as well as NMR spectroscopists, and will push the development of both fields. It covers the latest advances, for example high field DNP and ultrafast MAS methodologies, and show how these novel NMR methods characterize various synthetic and natural polymers.
Helicopter pilots in Vietnam kidded one another about being nothing but glorified bus drivers. But these "rotor heads" saved thousands of American lives while performing what the Army classified as the most dangerous job it had to offer. One in eighteen did not return home. Tom A. Johnson flew the UH-1 "Iroquois" -- better known as the "Huey" -- in the 229th Assault Helicopter Battalion of the First Air Cavalry Division. From June 1967 through June 1968, he accumulated an astonishing 1,600 flying hours (1,150 combat and 450 noncombat). His battalion was one of the most highly decorated units in the Vietnam War and, as part of the famous First Air Cavalry Division, helped redefine modern warfare. With tremendous flying skill, Johnson survived rescue missions and key battles that included those for Hue and Khe Sanh and operations in the A Shau and Song Re valleys, while many of his comrades did not. His heartfelt and riveting memoir will strike a chord with any soldier who ever flew in the ubiquitous Huey and any reader with an interest in how the Vietnam War was really fought.

Nanomaterials contain some unique properties due to their nanometric size and surface functionalization. Nanomaterial functionalization also affects their compatibility to biocompatibility and toxicity behaviors. environment and living organism. This makes functionalized nanomaterials a material with huge scope and few challenges. This book provides detailed information about the nanomaterial functionalization and their application. Recent advancements, challenges and opportunities in the preparation and applications of functionalized nanomaterials are also highlighted. This book can serve as a reference book for scientific investigators, doctoral and post-doctoral scholars; undergrad and gr...

La materia è intelligente. Solitamente pensiamo i materiali che ci circondano come semplici strumenti, passivi e incapaci di interagire con l’ambiente in modo complesso, ma a ben guardare non è affatto così. Numerosi materiali sono in grado di adattarsi agli stimoli che ricevono, di assemblarsi e ripararsi in autonomia e, in alcuni casi, di conservare una memoria del proprio passato. L’intelligenza di questi materiali è, naturalmente, tutt’altra cosa rispetto all’intelligenza umana: se la nostra concezione convenzionale di ‘intelligenza’ è essenzialmente basata su sistemi centralizzati di controllo come il cervello, un materiale possiede un’intelligenza diffusa in tutte le parti che lo compongono. È evidente che questa consapevolezza può cambiare profondamente l’approccio che abbiamo alla scienza e alla tecnologia, e forse anche alla vita stesssa. Davanti alle sfide tecnologiche e sociali che ci aspettano, la capacità di ripensare i materiali come una parte attiva della nostra vita e della nostra cultura, sfruttando la loro capacità di interagire in modo intelligente con il proprio ambiente, potrebbe essere la chiave per il futuro della nostra specie.
