【自然小科普】：CO2吸附材料正在研制中
　　A novel porous（多孔渗水的） material that has unique carbon dioxide retention（保留） properties has been developed through research led by The University of Nottingham． The findings， published in the peer－reviewed journal Nature Materials， form part of ongoing efforts to develop new materials for gas storage applications and could have an impact in the advancement of new carbon capture products for reducing emissions from fossil fuel processes．
　　It focuses on the metal organic framework NOTT－202a， which has a unique honeycomb－like structural arrangement and can be considered to represent an entirely new class of porous material．
　　Most importantly， the material structure allows selective adsorption of carbon dioxide －－ while other gases such as nitrogen， methane and hydrogen can pass back through， the carbon dioxide remains trapped in the materials nanopores， even at low temperatures．
　　Unique material
　　Lead researcher Professor Martin Schr&der， in the University's School of Chemistry， said： &The unique defect structure that this new material shows can be correlated directly to its gas adsorption properties． Detailed analyses via structure determination and computational modelling have been critical in determining and rationalising the structure and function of this material．&
　　The research team －－ which is included Dr Sihai Yang， Professor Alexander Blake， Professor Neil Champness and Dr Elena Bichoutskaia at Nottingham －－ collaborated on the project with colleagues at the University of Newcastle and Diamond Light Source and STFC Daresbury Laboratory．
　　NOTT－202a consists of a tetra－carboxylate ligands －－ a honeycomb like structure made of a series of molecules or ions bound to a central metal atom －－ and filled with indium（铟） metal centres． This forms a novel structure consisting of two interlocked frameworks．
　　Innovative solutions
　　State－of－the－art X－ray powder diffraction measurements at Diamond Light Source and advanced computer modelling were used to probe and gain insight into the unique carbon dioxide capturing properties of the material．
　　The study has been funded by the ERC Advanced Grant COORDSPACE and by an EPSRC Programme Grant ChemEnSus aimed at applying coordination chemistry to the generation of new multi－functional porous materials that could provide innovative solutions for key issues around environmental and chemical sustainability．
　　These projects incorporate multi－disciplinary collaborations across chemistry， physics and materials science， and aim to develop new materials that could have application in gas storage， sieving and purification， carbon capture， chemical reactivity and sensing．

Effects of coal dust and temperature on CO2 emission in two soil types in Shanxi Province煤粉尘添加量与温度对山西省两种土壤碳释放规律的影响
,,,,,,刘平,,,,,
Keywords: ,,,,Shanxi Province煤粉尘,,,,,
采用室内培养试验, 观测不同温度和不同煤粉尘用量条件下山西省电厂土和焦化厂土两种土壤的碳释放规律。结果表明, 室温(16~23 ℃)和25 ℃恒温下, 培养前期(4~9 d)土壤CO2 的释放量均为最大, 且25 ℃ 恒温培养土壤CO2 的释放量是室温条件下的2 倍左右。随煤粉尘添加量的增加, 土壤CO2 的释放量显著增加,且土壤活性有机质相应增加, 添加高量煤粉尘土壤CO2 的释放量最高达57.5 mg·kg-1·d-1, 两种土壤活性有机碳的增幅为0.3~3.8 g·kg-1。不同温度和不同煤粉尘用量条件下电厂土释放的CO2 均高于焦化厂土, 可能是电厂土含有较高的有机碳和较低的黏粒所致。由此可知, 温度是影响土壤有机碳分解的主要因素, 其次是添加煤粉尘的量, 土壤理化性质也是原因之一。本研究表明, 煤粉尘的降落一方面增加了土壤CO2 的释放, 另一方面增加了土壤碳库。

3秒自动关闭窗口H2O的英文叫法,有说H two O的习惯么水的英文学名是hydrogen oxide那外国人见到H2O会将其读做H two
有.私底下,大量的教授们都那么读.像CO2这种,基本都是读 C O two.口语可以,书面语就不行了
