| 1 | Dependence of nitrogen concentration in type Ib diamonds on synthesis temperature显示文摘Type Ib diamonds were grown by the temperature gradient method (TGM) at 5.5 GPa and 1500-1560 K in a china-type cubic anvil high pressure apparatus using Ni70Mn25Co5 alloy as solvent/catalyst. The concentration of nitrogen (CN) in type Ib diamonds synthesized at different synthesis temperatures was measured by a Fourier transform infrared (FTIR) spectrometer. The dependence of CN in diamond on synthesis temperature was studied. For the type Ib diamonds synthesized using Ni70Mn25Co5 as catalyst, its CN decreases along with the increase of synthesis temperature. | TIAN Yu JIA XiaoPeng ZANG ChuanYi LI ShangSheng XIAO HongYu ZHANG YaFei HUANG GuoFeng LI Rui HAN QiGang MA LiQiu LI Yong CHEN XiaoZhou ZHANG Chong MA HongAn | 2009 | Chinese Science Bulletin2009，54，9： | 5 |

| 3 | The effect of surface-free energy and microstructure on the condensation mechanism of water vapor显示文摘Obtaining high-water-yield drinking water in arid areas without consuming energy is still a global challenge.Since water vapor is ubiquitous,atmospheric water harvesting technologies are undoubtedly one of the most promising candidates.A typical water condensation process is analyzed in this paper(nucleation,self-growth,coalescence and sliding).The mechanisms of interactions between adsorbate and water vapor are discussed.The effect of surface-free energy and microstructure on water vapor condensation is described.Finally,the main problems in developing more efficient,high-water-mass and high-cycle-stability atmospheric water collectors are summarized,and the future development trend has been prospected. | Shangsheng Zhang Shuman Xu Yang Liu Ruicheng Lei Tianli Guo Yao Yao Shangyu Gao Jun Ding Zengzhi Zhang | 2023 | Progress in Natural Science:Materials International2023，33，1： | 0 |
| 4 | Core-shell-embedded Mesoporous Silica Capsules for Atmospheric Water Harvesting显示文摘A one-step ultrasonic mechanical method was used to synthesize a kind of atmospheric water harvesting material with high water harvesting performance in a wide relative humidity(RH)range,especially at low RH(RH<40%),namely,mesoporous silica capsule(MSC)with core-shell structure.Transmission electron microscopy(TEM),nitrogen adsorption and other characterization techniques were used to study the formation process of nano-microspheres.A new mechanism of self-adaptive concentration gradient regulation of silicon migration and recombination core-shell structure was proposed to explain the formation of a cavity in the MSC system.The core-shell design can enhance the specific surface area and pore volume while maintaining the monodispersity and mesoporous size.To study the water harvesting performance of MSC,solid silica nanoparticles(SSN)and mesoporous silica nanoparticles(MSN)were prepared.In a small atmospheric water collection test(25℃,40%RH),the water vapour adsorption and desorption kinetics of MSC,SSN,MSN and a commercial silica gel(CSG)were compared and analyzed.The results show that the MSC with mesoporous channels and core-shell structure can provide about 0.324 gwater/gadsorbent,79%higher than the CSG(0.181 gwater/gadsorbent).It is 25.1%higher than that of 0.259 gwater/gadsorbentof un-hollowed MSN and 980%higher than that of0.03 gwater/gadsorbentof un-hollowed SSN.The material has a large specific surface area and pore volume,simple preparation method and low cost,which provides a feasible idea for realising atmospheric water collection in arid and semi-arid regions. | ZHANG Shangsheng XU Shuman LEI Ruicheng PAN Yuliang MA Tao ZHANG Zheng LIU Chunsheng ZHANG Zengzhi | 2023 | Journal of Wuhan University of Technology(Materials Science)2023，38，5： | 0 |
