Liquid Crystals In Biotribology

Download or read book Liquid Crystals in Biotribology written by Sergey Ermakov and published by Springer. This book was released on 2015-07-11 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the theoretical and experimental studies confirming the concept of the liquid-crystalline nature of boundary lubrication in synovial joints. It is shown that cholesteric liquid crystals in the synovial liquid play a significant role in the mechanism of intra-articular friction reduction. The results of structural, rheological and tribological research of the creation of artificial synovial liquids containing cholesteric liquid crystals in natural synovial liquids are described. These liquid crystals reproduce the lubrication properties of natural synovia and provide a high chondroprotective efficiency. They were tested in osteoarthritis models and in clinical practice.

Download or read book Liquid-Crystal Nanomaterials written by Sergey F. Ermakov and published by Springer. This book was released on 2018-02-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the tribological, rheological and optical properties of liquid-crystal nanomaterials as well as lubricant media. It also describes the formation of liquid-crystal materials and the application of cholesteric liquid-crystal compounds in technical friction units and in human and animal joints. Further, it shows the connection between the tribological and other physical properties of liquid-crystal cholesterol compounds and develops a lubricity conceptual model of cholesteric–nematic, liquid-crystalline nanostructures on the basis of physical and energetic interpretations. This general model is valid for all surfaces and friction pairs, including biopolymers, and could lead to applications of cholesteric liquid-crystalline nanomaterials in different friction units and tribosystems as well as in the treatment of joint diseases.

Download or read book Materials For Total Joint Arthroplasty: Biotribology Of Potential Bearings written by Robert Sonntag and published by World Scientific. This book was released on 2015-10-14 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: The replacement of a degenerated joint such as the hip and knee is one of the most outstanding interventions that allows the medical community to restore the patient's quality of life. However, today's patient is increasingly younger and more active and this presents a challenge for the orthopaedic community as a greater demand has been created for a longer lasting artificial joint that can allow the patient to maintain their lifestyle and thus new approaches in biotribology have been focused on this area of research.This invaluable book provides a broad introduction to the boundary conditions, developments and latest research activities already available to the surgeon and offers an insight into solutions being developed for new high performance bearings in joint replacements. The contributors are leading experts in their field and this is the first complete volume to bring together such unique insights. Orthopaedic engineers, surgeons and researchers concerned with new biomaterials would find this a vital reference volume to evaluate the latest state of research in the area.

Available in PDF, EPUB and Kindle. Book excerpt: Surfactants play a critical role in Tribology controlling friction, wear, and lubricant properties such as emulsification, demulsification, bioresistance, oxidation resistance, rust prevention and corrosion resistance. This is a critical topic for new materials and devices particularly those built at the nanoscale. This newest volume will address important advances, methods, and the use of novel materials to reduce friction and wear. Scientists from industrial research and development (R&D) organizations and academic research teams in Asia, Europe, the Middle East and North America will participate in the work.
