China University of Petroleum(East China)has developed an inexpensive and environmentally friendly TiO2 catalyst for dehydrogenation of low-carbon alkanes,which is an excellent substitute for the Pt series catalysts(with high production cost)and Cr series
Recently,the 300 kt/a process design package(PDP)for manufacturing caprolactam via gas-phase re-arrangement of cyclohexanone-oxime developed by the SINOPEC Research Institute of Petroleum Processing(RIPP)as the leading institution has passed the technical
An approach for dominating the channel form of the flexible MIL-53(Fe)was developed by using a surfactant-assisted modified method.The surfactant tetraethylammonium hydroxide(TEAOH)can control the channel form of MIL-53(Fe)to be a“closed-pore”form,whereas
The China University of Petroleum(East China)has introduced the metal atoms into the mordenite zeolite framework by means of the in-situ modification method to obtain the metal modified zeolite with a strong interactive and stable structure.The metal cent
Recently the project“Development of high-efficiency acrylonitrile catalyst and commercial test of improved type SANC-11+catalyst for producing acrylonitrile”developed by the SINOPEC Shanghai Research Institute of Petrochemical Technology(SRIPT)has passed
Recently,the process design package(PDP)for a 600 kt/a moving-bed propane dehydrogenation to propylene(PDH)unit,which was jointly developed by the SINOPEC Luoyang Engineering Company(LEC)and the Research Institute of Petroleum Processing(RIPP),has passed
A variety of catalysts for converting trace acetylene contained in ethylene have been developed by the East China University of Science and Technology(ECUST),including the supported Ni-Ga-Pd catalyst and the highly-dispersed bifunctional Pd-In2
The CAS Dalian Institute of Chemical Physics(DICP)has developed a process for conversion of naphtha feed,which is characteristic of adjustable proportion of products(including low-carbon olefins,light aromatic hydrocarbons and high quality gasoline).The s
我国人口流动速度加快,人户分离的流动人口数占到中国总人口数四分之一以上。我国已经进入“大流动时代”,适应流动社会的治理尤显重要。流动社会产生了新的不均衡,矛盾更加复杂,对社会融合的治理要求更高,也亟需面对“新生代”流动人口的治理需求。流动社会的形成是改革开放的必然结果,现在实现现代化都市圈重点战略还要进一步促进流动,流动社会治理面临严峻挑战。提升流动社会治理水平,需要抓住“新生代”重点人群,做足社区融合文章,搭建多元主体协同治理机制,发挥市场配置治理资源机制,借助数字经济赋能打造智慧治理格局。
<strong>Background:</strong> Malnutrition is a strong predictor of prognosis in maintenance hemodialysis patients (MHD). We previously proposed a new and simple protein-energy wasting (PEW) score that appears to be useful for assessing the ris
