Download or read book Glassy Materials Based Microdevices written by Giancarlo C. Righini and published by MDPI. This book was released on 2019-02-28 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microtechnology has changed our world since the last century, when silicon microelectronics revolutionized sensor, control and communication areas, with applications extending from domotics to automotive, and from security to biomedicine. The present century, however, is also seeing an accelerating pace of innovation in glassy materials; as an example, glass-ceramics, which successfully combine the properties of an amorphous matrix with those of micro- or nano-crystals, offer a very high flexibility of design to chemists, physicists and engineers, who can conceive and implement advanced microdevices. In a very similar way, the synthesis of glassy polymers in a very wide range of chemical structures offers unprecedented potential of applications. The contemporary availability of microfabrication technologies, such as direct laser writing or 3D printing, which add to the most common processes (deposition, lithography and etching), facilitates the development of novel or advanced microdevices based on glassy materials. Biochemical and biomedical sensors, especially with the lab-on-a-chip target, are one of the most evident proofs of the success of this material platform. Other applications have also emerged in environment, food, and chemical industries. The present Special Issue of Micromachines aims at reviewing the current state-of-the-art and presenting perspectives of further development. Contributions related to the technologies, glassy materials, design and fabrication processes, characterization, and, eventually, applications are welcome.

Download or read book Fabrication of Complex Optical Components written by Ekkard Brinksmeier and published by Springer Science & Business Media. This book was released on 2012-09-13 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: High quality optical components for consumer products made of glass and plastic are mostly fabricated by replication. This highly developed production technology requires several consecutive, well-matched processing steps called a "process chain" covering all steps from mold design, advanced machining and coating of molds, up to the actual replication and final precision measurement of the quality of the optical components. Current market demands for leading edge optical applications require high precision and cost effective parts in large volumes. For meeting these demands it is necessary to develop high quality process chains and moreover, to crosslink all demands and interdependencies within these process chains. The Transregional Collaborative Research Center "Process chains for the replication of complex optical elements" at Bremen, Aachen and Stillwater worked extensively and thoroughly in this field from 2001 to 2012. This volume will present the latest scientific results for the complete process chain giving a profound insight into present-day high-tech production.

Download or read book Precision Injection Molding written by Jehuda Greener and published by Hanser Publications. This book was released on 2006 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key aspects of the production of high precision components is the need to meet extremely tight dimensional tolerances, typically in the submicron range, and maintain these tolerances over the practical lifetimes of the molded articles. In addition, as many of the precision components are utilized in various optoelectronic systems and devices, control of optical and electrical properties is often crucial. The strict control of dimensional and electro-optical properties requires a systematic reexamination of the conventional injection-molding process with special consideration of its impact on the dimensions and electro-optical characteristics of the molded article. This volume examines precision injection molding from different perspectives, covering materials, process and hardware aspects of the technology, with special emphasis on the dimensional integrity and stability of the molded components. Special topics covered in this volume include: dimensional stability of molded plastics, models for warpage development, compact disc molding, process control, crystallization phenomena in injection molding, micro-molding and microfluidics.

Available in PDF, EPUB and Kindle. Book excerpt: In the science of physics, elasticity is the ability of a deformable body (e.g., steel, aluminum, rubber, wood, crystals, etc.) to resist a distorting effect and to return to its original size and shape when that influence or force is removed. Solid bodies will deform when satisfying forces are applied to them. Elasticity solution of materials will be grouped in forms of linear and nonlinear elasticity formulations. The main subject of this book is engineering elasticity and consists of five chapters in two main sections.
