| lab 6 diffusion: Multiphased Ceramic Materials Wei-Hsing Tuan, Jin-Kun Guo, 2013-04-17 In many fields of thermomechanical applications, such as advanced gas turbine, thermal protection of space planes, oil and coal electric generation, advanced brake devices, etc. high performance materials are needed. Lacking of toughness and reliability, monolithic ceramics had reached their limits and multi-phase - terials are expected as the most promising candidates. Apart from the impro- ment on the thermomechanical performance, more than one function, such as magnetic, electrical and optical functions, can be incorporated simultaneously into the multi-phase material. However, several key problems remained to be solved in the near future. These problems include microstructure complexity, process challenge, machining ability and the most important cost issue. Fourteen scientists from 9 leading research - stitutes across Taiwan Strait are invited to give their view and experimental e- dence on solving the above problems. These reports highlight the principles of - signing delicate microstructure and novel processing routes. The potential of improving machining ability is also demonstrated. However, the most critical cost problem remained to be solved. In light of the economic surge in China in recent years, the market demands more technology breakthrough. The market can accept value-added products. It further indicates the importance of developing of multi-phase materials with multi-functions. Along with the market growth, the cost problem will be solved soon as the mass production technology becoming available. |

| lab 6 diffusion: W Tungsten , 2013-11-11 The present supplement volume, A 7, is the first of a triad, A 5 to A 7, dealing with the chemical reactions of metallic tungsten. It describes the reactions with inorganic and organic compounds, except for formation reactions of organotungsten compounds. Volume A 6, to appear at the beginning of 1988, will cover the reactions of tungsten with metallic elements. Volume A 5, in preparation for 1988/89, will contain the reactions with nonmetallic elements and, in addition, cover the electrochemistry of tungsten. With the appearance of this last volume, the present knowledge of the chemistry of tungsten will be compiled in more than 1000 pages. In the Gmelin main volume on tungsten, published in 1933, the presentation of the information then available on the same subject required less than 6 pages. This enormous increase in relevant data over the last fifty years is stupefying, considering the fact that tungsten is a rather inert metal which is resistant to most chemical agents up to high temperatures.With afew exceptions,in fact, it was not so much the reactions of bulk tungsten which attracted the interest of the experimenters as the reactions taking place at its surface. This comes about for practical as well as scientific reasons. |

| lab 6 diffusion: Light-Matter Interactions Towards the Nanoscale Maura Cesaria, Antonio Calà Lesina, John Collins, 2022-05-14 The investigation of light-matter interactions in materials, especially those on the nanoscale, represents perhaps the most promising avenue for scientific progress in the fields of photonics and plasmonics. This book examines a variety of topics, starting from fundamental principles, leading to the current state of the art research. For example, this volume includes a chapter on the sensing of biological molecules with optical resonators (microspheres) combined with plasmonic systems, where the response this system are described in a fundamental and elegant manner using coupled mode theory. Symmetry plays a major role in the book. One chapter on time reversal symmetry in electromagnetic theory describes how to control the properties of light (e.g. scattering and directionality of the flow of light) in materials with certain topological invariants. Another chapter where symmetry is prominent reformulates, using a gentle and pedagogical approach, Maxwell’s Equations into a new set of fields that reveal a “handedness” symmetry in electromagnetic theory, which can be applied to photonic systems in, for example, the sensing of chiral molecules and understanding the conditions for zero reflection. Also, for students and researchers starting in the field of nanoplasmonics, the book includes a tutorial on the finite element time domain simulation of nanoplasmonic systems. Other topics include photonic systems for quantum computing, nanoplasmonics, and optical properties of nano and bulk materials. The authors take a pedagogical approach to their topic, making the book an excellent reference for graduate students and scientists starting in the fields of photonics or plasmonics. |
