Biomedical Applications of Electrospinning and Electrospraying describes the principles and laboratory set up for electrospinning and electrospraying, addressing a range of biomedical applications. Sections cover novel combinational approaches, such as electrospinning/spraying and 3D printing. Electrospinning has evolved from being a technique to prepare random networks of textile fibers to a technique to fabricate highly ordered patterns of biomedical materials of defined scale. The technological advancements in recent years with regard to the way the jet is facilitated, how the jet path is controlled, and how the fibers are collected have provided invaluable insights into controlled fabrication of a material of choice. Additionally, the electrospray technique has also evolved from being a technique to prepare food formulations to a technique to prepare cell encapsulated beads for transplantation in clinics. Several innovations in this line, such as those leading to core-shell materials have tremendously changed the way the technique is used. Thus, a combinational approach using electrospinning, electrospraying and 3D printing has emerged.

This book traces the relationship between ideas and methodological perspectives in economics to the fields of philosophy and the physical sciences. It is aimed at students of economics who want to learn about the philosophical underpinnings and scientific foundations of contemporary economic theory. The authors show how advances in scientific knowledge have had an impact on philosophy that in turn influenced the development of economic thought.

The fourth Chinese Peptide Symposium, hosted by Peking University, was held at Chengdu, China on July 21 25, 1996 with 164 participants, including 45 scientists from abroad, representing 12 countries. The four day conference was both intense and spiritually rewarding. Our goal for CPS 96 was to provide a forum for the exchange of knowledge, cooperation and friendship between the international and Chinese scientific communities, and we believe this goal was met. The symposium consisted of 10 sessions with 55 oral and 78 poster presentations, including synthetic methods, molecular diversity and peptide libraries, structure and conformation of peptides and proteins, bioactive peptides, peptide immunology, De Novo design and synthesis of proteins and peptides, ligand receptor interactions, the chemistry biology interface and challenging problems in peptides. Theenthusiasticcooperationandexcellentcontributionsweregratifying andtheactive response of the invited speakers contributed to the success of the symposium. The presentations were of excellent caliber and represented the most current and significant aspects of peptide science. Dr. James P. Tam and Dr. Jie Cheng Xu were the recipients of 'The Cathay Award' sponsored by the H. H. Liu Education Foundation, offered for their seminal contributions in peptide science and the Chinese Peptide Symposium. Four outstanding young scientists were selected by the organizing committee to receive awards sponsored by Haikou Nanhai Pharmaceutical Industry Co. Ltd. (Zhong He Group).
