Работа направлена на установление закономерностей изменения сдвиговой упругости, возникающих при структурной релаксации металлических стекол на основе Pd и Zr. Измерения модуля сдвига выполнялись на частотах около 500 кГц. Несмотря на отличия в физических свойствах исследованных металлических стекол (химический состав, стеклообразующая способность, температуры стеклования и др.), наблюдаются определенные общие закономерности релаксации их сдвиговой упругости при термообработке.   ИСТОЧНИК ФИНАНСИРОВАНИЯ Работа поддержана грантом Минобрнауки РФ № 3.1310.2017/4.6.   БЛАГОДАРНОСТИ Автор выражает благодарность проф.

AbstractThe following article is based on the presentation given by George M. Whitesides, recipient of the 2000 MRS Von Hippel Award, the Materials Research Society's highest honor, at the 2000 MRS Fall Meeting in Boston on November 29, 2000. Whitesides was cited for “bringing fundamental concepts of organic chemistry and biology into materials science and engineering, through his pioneering research on surface modification, self-assembly, and soft lithography.” The article focuses on the growing role of organic chemistry in materials science. Historically, that role has been to provide organic polymers for use in structures, films, fibers, coatings, and so on. Organic chemistry is now emerging as a crucial part of three new areas in materials science. First, it provides materials with complex functionality. Second, it is the bridge between materials science and biology/medicine. Building an interface between biological systems and electronic or optical systems requires close attention to the molecular level of that interface. Third, organic chemistry provides a sophisticated synthetic entry into nanomaterials. Organic molecules are, in fact, exquisitely fabricated nanostructures, assembled with precision on the level of individual atoms. Colloids are a related set of nanostructures, and organic chemistry contributes importantly to their preparation as well.

ABSTRACTThe Materials Science and Engineering Laboratory at NIST has augmented its laboratory-based research in support of the U.S. commercial microelectronics industry by expanding its efforts in electronics packaging, interconnection and assembly (P/I/A) materials technologies. In conjunction with industry, university and other government agency partners, these new NIST efforts target materials technology issues that underlie the priorities contained within the various electronics industry technology roadmaps. A dominant aspect of the laboratory P/I/A program focuses on the in-situ metrology and data needs associated with the materials and complex material assemblies which comprise today's microelectronic components and circuits.

The following is an edited version of the Von Hippel Award address, given by recipient W.W. Mullins at the 1995 MRS Fall Meeting. Mullins received the Materials Research Society's highest honor “for pioneering and profound contributions to the understanding of grain boundary motion, morphological stability, the structure of surfaces and interfaces, and flow and diffusion as stochastic phenomena.” Mullins is University Professor Emeritus of Materials Science and Engineering at Carnegie-Mellon University.
