A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...

Social network analysis is used to study complex networks by analyzing static structure and dynamic changes. Nowadays micro-blog as a new social media is becoming the most popular communication platform. How to capture micro-blog network structure especially dynamic structure poses more scientific interest. In this paper, we choose Chinese micro-blog, Sina weibo, on topic of diabetes as our tes...

Some studies on the fabrication of micro-needles, micro-pillers, and micro-channels using SU-8 negative photoresist for MEMS and bio-applications are reported. The SU-8 processing technology was standardized for the purpose. Micro-pillars were fabricated on SU-8 polymer by soft lithographic technique. Micro-needles were realized on SU-8 film utilizing lensing effect of the etched groove structu...
