Research and development in nanostructured materials is one of the most intensely studied areas in science. As a result of
concerted R & D efforts, nanostructured electronic and magnetic materials have achieved commercial success. Specific examples
of novel industrially important nanostructured electronic and magnetic materials are provided. Advantages of nanocrystalline
magnetic materials in the context of both materials and devices are discussed. Several high technology examples of the use
of nanostructured magnetic materials are presented. Methods of processing nanostructured materials are described and the examples
of sol gel, rapid solidification and powder injection moulding as potential processing methods for making nanostructured materials
are outlined. Some opportunities and challenges are discussed. 相似文献

Interactive materials are at the forefront of current materials research with few examples in the literature. Researchers are inspired by nature to develop materials that can modulate and adapt their behavior in accordance with their surroundings. Stimuli-responsive systems have been developed over the past decades which, although often described as “smart,” lack the ability to act autonomously. Nevertheless, these systems attract attention on account of the resultant materials' ability to change their properties in a predicable manner. These materials find application in a plethora of areas including drug delivery, artificial muscles, etc. Stimuli-responsive materials are serving as the precursors for next-generation interactive materials. Interest in these systems has resulted in a library of well-developed chemical motifs; however, there is a fundamental gap between stimuli-responsive and interactive materials. In this perspective, current state-of-the-art stimuli-responsive materials are outlined with a specific emphasis on aqueous macroscopic interactive materials. Compartmentalization, critical for achieving interactivity, relies on hydrophobic, hydrophilic, supramolecular, and ionic interactions, which are commonly present in aqueous systems and enable complex self-assembly processes. Relevant examples of aqueous interactive materials that do exist are given, and design principles to realize the next generation of materials with embedded autonomous function are suggested. 相似文献

In recent years, three-dimensionally ordered macroporous (3DOM) materials have attracted tremendous interest in the field of photocatalysis due to the periodic spatial structure and unique physicochemical properties of 3DOM catalysts. In this review, the fundamentals and principles of 3DOM photocatalysts are briefly introduced, including the overview of 3DOM materials, the photocatalytic principles based on 3DOM materials, and the advantages of 3DOM materials in photocatalysis. The preparation methods of 3DOM materials are also presented. The structure and properties of 3DOM materials and their effects on photocatalytic performance are briefly summarized. More importantly, 3DOM materials, as a supported catalyst, are extensively employed to combine with various common materials, including metal nanoparticles, metal oxides, metal sulfides, and carbon materials, to enhance photocatalytic performance. Finally, the prospects and challenges for the development of 3DOM materials in the field of photocatalysis are presented. 相似文献

The report deals with the complex of problems concerning education of materials scientists and materials engineers. The development of materials science is described. It is attempted to estimate the future demand for materials scientists and materials engineers. Educational and organizational aspects of materials science and materials engineering in higher education are discussed. A selection of topics forming a possible core for materials science and materials engineering studies is presented. Finally, university-industry relations in the field of materials are discussed. A survey of materials programs in 133 higher education establishments in 13 countries has been made. The results of this survey are not included in the report, but they are available from OECD on request. 相似文献

The development of suitable materials for use in mhd generator is one of the most challenging areas. The very high temperatures
(∼ 2700 K) coupled with the highly corrosive seed-laden atmosphere limit the choice of materials in contact with the plasma
to just a few ceramic oxides. These materials in contact with the high temperature plasmas in mhd generator are simultaneously
subjected to stresses of mechanical, thermal, chemical and electromagnetic nature. The development and suitability of the
different potential electrode and insulator materials such as lanthanum chromite, zirconia-based materials, alumina, magnesia
etc. are reviewed with particular reference to the mhd channel materials programme in the mhd Project atbarc.
The operating experience with alumina-based ceramics and other materials under mhd operating conditions is also detailed.
This includes the specifications, processing, bonding of the ceramic materials, the test programme and evaluation. Also presented
are some of the novel processing techniques like plasma spraying and their application in the development of mhd materials.
The advantages and limitations of each of these materials and their principal mode of degradation while in service are also
discussed. 相似文献

Current bioelectronics are facing a paradigm shift from old-fashioned unrecyclable materials to green and degradable functional materials with desired biocompatibility. As an essential electromechanical coupling component in many bioelectronics, new piezoelectric materials are being developed with biodegradability, as well as desired mechanical and electromechanical properties for the next generation implantable and wearable bioelectronics. In this review, we provide an overview of the major advancements in biodegradable piezoelectric materials. Different natural (such as peptide, amino acids, proteins, cellulose, chitin, silk, collagen, and M13 phage) and synthetic piezoelectric materials (such as polylactic acid) are discussed to reveal the underlying electromechanical coupling mechanism at the molecular level, together with typical approaches to the alignment of orientation and polarization to boost their electromechanical performance. Meanwhile, in vivo and in vitro degradation manners of those piezoelectric materials are summarized and compared. Representative developments of typical electronic prototypes leveraging these materials are also discussed. At last, challenges toward practical applications are pointed out together with potential research opportunities that might be critical in this new materials research area. 相似文献
