NANOTUBES AND NANOWIRES

The field of nanotubes and nanowires is evolving at a rapid pace, with many potential applications in electronics, optics, and sensors, to name a few. In this special issue, several groups summarize some of these potential applications, although the list is by no means extensive. Rather, it is meant to serve as a flavor of and snapshot of the current state of the art in the field of nanowires and nanotubes. There is an ample mix of experimental, theoretical, and visionary material in this book to give the reader an indication of where the field is now, and where it is going. Two chapters on the electrostatics and quantum properties of Id FETs provide a snapshot of the understanding of device physics. One of the chapters focuses on a particular materials system (ZnO) for nanowire technology. Three chapters point to some of the potential applications, including sensors, memory, and high frequency electronics and systems.

МАҲАЛЛИЙ ХОМАШЁЛАР АСОСИДА ОЛИНГАН ИОНИТЛАРНИНГ ОРАЛИҚ МЕТАЛЛАР БИЛАН КОМПЛЕКСЛАРИ

Дунёда ишлаб чикариладиган полимер-металл комплекслар одатий металл катализаторларига қараганда активлиги юқорироқ бўлган катализаторлар сифатида органик реакцияларни олиб боришда кенг қўлланилиб келинмоқда. Бунга сабаб полимерлар сиртига металл атомлари нано ўлчамда эканлиги учун металл атомларининг умумий юзаси одатий ҳолатдаги металларга нисбатан жуда юқори бўлганлигидадир. Бундай полимер-металл катализаторлар ўзининг юқори самарадорлиги ва селективлиги билан ажралиб туради. Шунинг учун кимёвий жараёнларии сифатли ва юкори самарадорликда олиб бориш учун бундай турдаги катализаторлардан фойдаланиш алоҳида аҳамият касб этади.

NANOSTRUCTURES & NANOMATERIALS

Nanotechnology is design, fabrication and application of nanostructures or nanomaterials, and the fundamental understanding of the relationships between physical properties or phenomena and material dimensions. Nanotechnology deals with materials or structures in nanometer scales, typically ranging from subnanometers to several hundred nanometers. One nanometer is 1 0-3 micrometer or meter. Nanotechnology is a new field or a new scientific domain. Similar to quantum mechanics, on nanometer scale, materials or structures may possess new physical properties or exhibit new physical phenomena. Some of these properties are already known. For example, band gaps of semiconductors can be tuned by varying material dimension. There may be many more unique physical properties not known to us yet. These new physical properties or phenomena will not only satisfy everlasting human curiosity, but also promise new advancement in technology. For example, ultra-strong ultra-light multifunctional materials may be made from hierarchical nanostructures. Nanotechnology also promises the possibility of creating nanostructures of metastable phases with non-conventional properties including superconductivity and magnetism. Yet another very important aspect of nanotechnology is the miniaturization of current and new instruments, sensors and machines that will greatly impact the world we live in.

Бутун дунёда чукур нефт ва газ қудуқларини бурғулаш жараёнларини такомиллаштириш бўйича илмий-тадқиқот ишлари олиб борилмоқда, бундай қудуқлардаги юқори ҳарорат металл ускуналарни емирилишга ва уни авариявий ҳолатга олиб келади. Бурғу ва бурғулаш қурилмасининг бошқа айланувчи элементларига юқори ҳароратли таъсирни камайтириш мақсадида уларни, синтетик ва табиий усулларда олинадиган ёғлар билан мойлаш тавсия этилади. Улардан табиий усулда олинган ёғлар нисбатан қулай ва арзонроқ мойловчи хом-ашё ҳисобланади, чунки улар асосан маҳаллий мойлар, шунингдек чиқиндиларидан олинади.

Nanoscale Science and Technology

In the two years since we first started planning this book, so much has been written about nanotechnology that the subject really needs no introduction. Nanotechnology has been one of the first major new technologies to develop in the internet age, and as such has been the topic of thousands of unregulated, unrefereed websites, discussion sites and the like. In other words, much has been written, but not all is necessarily true. The press has also made its own, unique contribution: ‘nanotechnology will turn us all into grey goo’ makes for a good story (in some newspapers at least), and then there’s the 1960s image of nanotechnology, still present today, of Raquel Welch transported in a nanosubmarine through the bloodstream of an unsuspecting patient. This book isn’t about any of that! One thing that the recent press coverage of nanotechnology has achieved is to draw attention to the possible hazards which accompany any new technology and to pose relevant questions about the likely impact of the various facets of nanotechnology on our society. Whilst we would certainly encourage investigation and discussion of such issues, they do not fall within the remit of this book.

В лабораторной работе 1 рассматривается методика присвоения полного обозначения проектируемому электронному средству (ЭС) согласно классификатору единой системы конструкторской документации (ЕСКД). В соответствии с полученным вариантом технического задания в лабораторной работе необходимо определить код классификационной характеристики заданного ЭС.

Motion Mountain

The intensity with which small children explore their environment suggests that there is a drive to grasp the way the world works, a ‘physics instinct’, built into each of us. What would happen if this drive, instead of being stied during school education, as it usually is, were allowed to thrive in an environment without bounds, reaching from the atoms to the stars? Probably most adolescents would then know more about nature than most senior physics teachers today. ¿is text tries to provide this possibility to the reader. It acts as a guide in an exploration, free of all limitations, of physics, the science of motion. The project is the result of a threefold aim I have pursued since 1990: to present the basics of motion in a way that is simple, up to date and vivid.

Molecular Thermodynamics and Transport Phenomena

This book is intended for upper-level undergraduates and first-year graduate students in science and engineering. It is basically an introduction to the molecular foundations of thermodynamics and transport phenomena presented in a unified manner. The mathematical and physical science level sophistication are at the upper undergraduate level, and students who have been exposed to vector calculus, differential equations, and calculus-based physics should be adequately prepared to handle the material presented. There is also sufficient advanced material in each chapter or topic for first-year graduate students in science or engineering.

Modern Physics

Our objective in writing this book was to produce a textbook for a modern physics course of either one or two semesters for physics and engineering students. Such a course normally follows a full-year, introductory, calculus-based physics course for freshmen or sophomores. Before each edition we have the publisher send a questionnaire to users of modern physics books to see what needed to be changed or added. Most users like our textbook as is, especially the complete coverage of topics including the early quantum theory, subfi elds of physics, general relativity, and cosmology/astrophysics. Our book continues to be useful for either a one- or two-semester modern physics course. We have made no major changes in the order of subjects in the fourth edition.

Modern Quantum Mechanics

J. J. Sakurai was always a very welcome guest here at CERN, for he was one of those rare theorists to whom the experimental facts are even more interesting than the theoretical game itself. Nevertheless, he delighted in theoretical physics and in its teaching, a subject on which he held strong opinions. He thought that much theoretical physics teaching was both too narrow and too remote from application: "... we see a number of sophisticated, yet uneducated, theoreticians who are conversant in the LSZ formalism of the Heisenberg field operators, but do not know why an excited atom radiates, or are ignorant of the quantum theoretic derivation of Rayleigh's law that accounts for the blueness of the sky." And he insisted that the student must be able to use what has been taught: "The reader who has read the book but cannot do the exercises has learned nothing."
