Rare Metals, EarlyView.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Analysis on Regulation of P2P Online Lending Industry(HONGLING CATITAL as an example [PDF]
, 2016 近年来，P2P网络借贷行业进入了快速发展的阶段，每年的平台数量以及成交量均呈现数倍的增长，行业内出现了红岭创投、人人贷、陆金所等知名平台，而平台的运营模式也有所区别，不同的平台利用各自模式的特点进行大力推广，同时也出现了分化。部分平台由于有国有企业、上市公司的背景，更能够获取投资者的信任，规模越做越大，但更多的平台由于没有很好的“靠山”，在营销和推广上遭遇瓶颈，仅仅维持在一个相对低的规模水平，发展艰难，最终有一批P2P平台选择退出。 由于缺乏监管，市场上的P2P平台参差不齐，截止2015年12月 ...

A Study of Securities Research Based on Multi-level Capital Market [PDF]
, 2015 经过不断的发展，国内证券研究业务虽然摆脱了最初作为后方支持平台成本中心的困境，但目前主要定位仍为卖方研究，服务对象与盈利模式相对单一，并不能完全满足投资者投资需求与企业融资需求，也不利于大中小型券商协调、均衡发展。与此同时，随着多层次资本市场的逐步建立与完善，股市层次结构日趋优化、债券及衍生品市场迅速发展，各种投融资工具需求也呈现出了井喷式增长。面对立体化的资本市场发展机遇，不同类型证券研究机构应明确自身在新形势下的市场定位，充分发挥在不同研究领域的内外影响，力主摆脱国内证券研究同质化的困境 ...
