Engineering 2D Materials for High‐Current‐Density Electrocatalytic Water Splitting
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Water electrolysis is a key method for sustainable hydrogen production, using water as an abundant resource. However, efficient and stable operation at high current densities remains challenging due to energy losses, catalyst degradation, and limited ion–electron transport.

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

To Transport or Not to Transport: Post‐Growth Avenues for Transport Infrastructure Planning
Journal of Critical Infrastructure Policy, Volume 6, Issue 1, Spring/Summer 2025.Abstract Post‐growth literature has recently raised attention to the role of transport infrastructure planning in relation to global sustainability challenges and human wellbeing. Transport infrastructure can be a major obstacle to change, due to sunk costs, material intensity, and historical path dependencies.

Research on Path Planning for a Mobile Robot
, 2008 针对室内动态非结构化环境下的移动机器人路径规划问题,提出了一种能够将全局路径规划方法和局部路径规划方法相结合、将基于反应的行为规划和基于慎思的行为规划相结合的路径规划方法.全局路径规划器采用A*算法生成到达目标点的子目标节点序列;局部路径规划器采用改进的人工势场方法对子目标节点序列中相邻两节点进行路径平滑和优化处理.在考虑了移动机器人运动学约束的前提下,该方法不但能够充分利用已知环境信息生成全局最优路径,而且还能及时处理所遇到的随机障碍信息 ...
