The separation of CO_(2)/C_(2)H_(2)mixture by CO_(2)-selective sorbents is an energy-efficient C_(2)H_(2)purification technique,but is strategically challenging due to their similar molecular size and physicochemical ***,water is inevitable in CO_(2)/C_(2)H_(2)mixture and it is usually a significant barrier because of its competitive adsorption with CO_(2).To address this challenge,herein,we report the first example of metal–organic framework(MOF)that exhibits water-boosted CO_(2)adsorption and CO_(2)/C_(2)H_(2)separation by anchoring L-arginine(ARG)on the Zr6 cluster of *** CO_(2)affinity and capacity in the resulting MOF-808-ARG are markedly facilitated by the presence of water,while the C_(2)H_(2)adsorption is significantly ***,CO_(2)adsorption capacities in adsorption isotherm and breakthrough measurement are increased to 143%and 184%,*** addition,the wet MOF-808-ARG exhibits the record CO_(2)/C_(2)H_(2)selectivity of 1,180 under zero *** experiments reveal that CO_(2)/C_(2)H_(2)mixture can be completely separated and the result of mass spectrometry indicates that the C_(2)H_(2)purity in the outlet is up to 99.9%.In situ infrared(IR)results and density functional theory(DFT)calculations reveal the water-promoted CO_(2)adsorption mechanism that the formation of bicarbonate products in the presence of water is thermodynamically and kinetically more favorable than that without ***,MOF-808-ARG also possesses excellent water stability and excellent regeneration of CO_(2)*** work provides a new paradigm by transforming the negative effects of water into positive ones for CO_(2)/C_(2)H_(2)separation.

Herein,a novel sensor(TPE-UiO-66)was designed via anchoring monodentate tetraphenylethylene(TPE)onto UiO-66 *** combination of the distinct aggregation-induced emission(AIE)of TPE and the easy replacement of monodentate linker by guest phosphate,makes TPE-UiO-66 an ideal pltform for sensing HPO_(4)^(2-)。Experimental results indicate that TPE-UiO-66 can selectively sense HPO_(4)^(2-)from other common anions.

Geographical distribution and age composition of Euphausia superba larvae (Crustacea: Euphausiacea) in the South Shetland Islands region and southern Scotia Sea in relation to environmental conditions

Acta Oceanologica Sinica 2013年第11期32卷 59-67页

作者： GAO Qian XU Zhaoli huang hongliang CHEN Xuezhong FENG Chunlei LI Lingzhi Key and Open Laboratory of Marine and Estuarine Fisheries Ministry of AgricultureEast China Sea Fisheries Research InstituteChinese Academy of Fishery Sciences

Spatial distribution patterns of the different life stages of Euphausia superba in the region of the South Shet- land Islands and southern Scotia Sea （Antarctica） were assessed based on scientific survey data collected in lanuary and February of 2010. Adults, eggs, nauplii, metanauplii, calyptopis I-Ill, and furcilia I-II were found in the investigation. The abundance of larvae averaged 1 172.8 ind./mz, with calyptopis I and II as the dominant stages. Habitat occupancy patterns varied among Euphausia superba at different stages, and three sub-regions were identified by cluster analysis. The degree of larval development increased from west to east. Larvae were not observed north of the South Shetland Islands. Calyptopis I was predominant in the water between Elephant Island and the South Orkney Islands, which featured no thermocline. Older stages, including calyptopis II and III and furcilia I and II, were common in north and northeast of the South Orkney Islands, which were characterized by high temperature and high chlorophyll concentration. Distri- bution and abundance of the early life stages of E. superba were associated with specific environmental con- ditions. According to Biota-Environment matching （BIOENV）, the distributions of E. superba larvae were correlated with a combination of temperature at the surface and 200 m, and 0-100 m integrated chlorophyll a concentration.

A Fluorescent Zirconium-Based Metal-Organic Framework for Selective Detection of Nitro Explosives and Metal Ions

引用

Chinese Journal of Chemistry 2017年第7期35卷 1091-1097页

作者： YuanzheTang hongliang huang Yaguang Peng Qunqun Ruan KekeWang Pengda Yi Dahuan Liu Chongli Zhong Beijing Advanced Innovation Center for Soft Matter Science and Engineering State Key Laboratory of Organic-Inorganic Composites Beijing University of Chemical Technology Beo'ing 100029 China

In this work, a new porous Zrobased metal-organic framework （MOF） with a large Brunner-Emmet-Teller （BET） surface area was prepared by the solvothermal method using 4,4＇-（naphthalene-1,4-diyl）dibenzoic acid （NDDA） as the organic ligand, and the luminescent detection performance was studied systematically. The experiments comb- ing with computations indicate that the as-synthesized material can sensitively and selectively detect nitro explo- sives and metal ions, especially for 2,4,6-trinitrophenol （TNP） and Fe3＋, due to the possible electron transfer from inorganic moieties to organic moieties with naphthalene part. Interestingly, owing to its high porosity and large sur- face area, this Zr-MOF showed quick luminescent response time （in 1 min） for TNP and Fe3＋. The results obtained may provide useful information for the design of MOFs with the large permanent porosity in sensing applications for large molecules in the future.
