Patent number: 8894966Abstract: A micro-mixer and use thereof for synthesis of barium sulfate particles is disclosed. The micro-mixer includes feeding tubes, reservoirs, a mixing channel, a buffer reservoir and a sampling tube. The mixing channel is made of hydrophobic materials and processed into a spiral structure, in which baffles are set in interval arrangement at both sides of the channel wall. The types of the baffles include leaning-forward baffles, vertical baffles and leaning-backward baffles. Setting the baffles helps produce local secondary flow in the mixer, which enhances fluids mixing process. The micro-mixer is suitable to rapid reactions or precipitation processes, whose reaction time is much less than mixing time, and has broad application prospects in many fields involving mixing reaction such as pharmaceutical and chemistry industry.Type: GrantFiled: October 31, 2013Date of Patent: November 25, 2014Assignees: Institute of Process Engineering, Chinese Academy of Sciences, Nanjing Ziuzhang Chemical Technology Co., LtdInventors: Chao Yang, Xi Wang, Yumei Yong, Guangji Zhang, Jingcai Cheng, Xin Feng, Xiangyang Li, Weipeng Zhang, Yuanyuan Li, Zaisha Mao

Patent number: 8642765Abstract: A novel class of azaindole-indole coupled derivatives, their preparation methods, pharmaceutical compositions containing the same and the uses thereof. The common structural feature of these derivatives is that they are coupled by azaindole and indole bi-molecule at different positions, forming extended pi-conjugated systems. Such derivatives inhibited cell growth and proliferation by various mechanisms. The present compounds have improved solubility, increased bioavailability, and thus have enhanced drug actions, and reduced medical dosages and undesired responses.Type: GrantFiled: June 6, 2008Date of Patent: February 4, 2014Inventors: Jingcai Cheng, Qizheng Yao, Zhaohui Wang, Weiyi Hua
