The Legal Environment for Copyright Protection and Trust Management in China
This paper surveys the legal and regulatory environment surrounding copyright protection technologies, focusing on China in particular. The paper begins with a discussion of some of the interactions between law and technology in copyright protection, which has led to the creation of international treaties to protect the technologies that protect copyrights. A comparison of the various national responses to these conventions is presented, followed by a discussion of the structure and development of the relatively advanced Chinese system for copyright protection technology. The last section outlines some of the unique challenges that have arisen in China for copyright protection technologies and the businesses that depend upon them.

A Critical Assessment on Functional Attributes and Degradation Mechanism of Membrane Electrode Assembly Components in Direct Methanol Fuel Cells
Direct methanol fuel cells (DMFC) are typically a subset of polymer electrolyte membrane fuel cells (PEMFC) that possess benefits such as fuel flexibility, reduction in plant balance, and benign operation. Due to their benefits, DMFCs could play a substantial role in the future, specifically in replacing Li-ion batteries for portable and military applications. However, the critical concern with DMFCs is the degradation and inadequate reliability that affect the overall value chain and can potentially impede the commercialization of DMFCs. As a consequence, a reliability assessment can provide more insight into a DMFC component’s attributes. The membrane electrode assembly (MEA) is the integral component of the DMFC stack. A comprehensive understanding of its functional attributes and degradation mechanism plays a significant role in its commercialization. The methanol crossover through the membrane, carbon monoxide poisoning, high anode polarization by methanol oxidation, and operating parameters such as temperature, humidity, and others are significant contributions to MEA degradation. In addition, inadequate reliability of the MEA impacts the failure mechanism of DMFC, resulting in poor efficiency. Consequently, this paper provides a comprehensive assessment of several factors leading to the MEA degradation mechanism in order to develop a holistic understanding.
