2Surface functionalized N-C-TiO_(2)/C nanocomposites derived from metal-organic framework in water vapour for enhanced photocatalytic H generation显示文摘Surface-functionalized nitrogen/carbon co-doped polymorphic TiO_(2) phase junction nanoparticles uniformly distributed in porous carbon matrix were synthesized by a simple one-step pyrolysis of titanium based metal-organic framework(MOF),NH_(2)-MIL^(-1)25(Ti) at 700℃ under water vapour atmosphere.Introducing water vapour during the pyrolysis of NH_(2)-MIL^(-1)25(Ti) not only functionalizes the derived porous carbon matrix with carboxyl groups but also forms additional oxygen-rich N like interstitial/intraband states lying above the valence band of TiO2 along with the self-doped carbo n,which further narrows the energy band gaps of polymorphic TiO2 nanoparticles that enhance photocatalytic charge transfer efficiency.Without co-catalyst,sample N-C-TiO2/CArW demonstrates H_(2) evolution activity of 426 μmol gcat-1h^(-1),which remarkably outperforms commercial TiO_(2)(P-25) and N-C-TiO_(2)/CAr with a 5-fold and 3-fold H_(2) generation,respectively.This study clearly shows that water vapour atmosphere during the pyrolysis increases the hydrophilicity of the Ti-MOF derived composites by functionalizing porous carbon matrix with carboxylic groups,as well as enhancing the electrical conductivity and charge transfer efficiency due to the formation of additional localized oxygen-rich N like interstitial/intraband states.This work also demonstrates that by optimizing the anatase-rutile phase composition of the TiO2 polymorphs,tuning the energy band gaps by N/C co-doping and functionalizing the porous carbon matrix in the N-C-TiO2/C nanocomposites,the photocatalytic H_(2) generation activity can be further enhanced.Mian Zahid Hussain Zhuxian Yang Bart van der Linden Zheng Huang Quanli Jia Erik Cerrato Roland A.Fischer Freek Kapteijn Yanqiu Zhu Yongde Xia 2021Journal of Energy Chemistry2021,30,6:3
3中国香港新记录的十个分类单元(英文)显示文摘中国香港位于热带北缘,其植被在历史上曾遭到大规模破坏,近几十年来逐渐恢复。香港植物标本采集有很长的历史,迄今为止已记录的维管植物超过2 170种,然而新种和新分布仍在不断增加。在最近的野外工作中,作者发现10种在香港新记录到的维管植物,分别是唇边书带蕨[Haplopteris elongata (Swartz) E. H.Crane]、雷公连[Amydrium sinense (Engl.) H. Li]、百足藤[Pothos repens (Lour.) Druce]、四川轮环藤(Cycleasutchuenensis Gagnep.)、山黑豆(Dumasia truncata Siebold&Zucc.)、倒心叶珊瑚[Aucuba obcordata (Rehder) Fu ex W. K. Hu et Soong]、竹叶榕(Ficus stenophylla Hemsl.)、长叶冠毛榕[F. gasparriniana var. esquirolii (H. Lév.&Vaniot) Corner]、硬叶冬青(Ilex ficifolia C. J. Tseng ex S. K. Chen et Y. X. Feng)、假福王草[Paraprenanthes sororia(Miq.) C. Shih.]。雷公连属(Amydrium Schott)、山黑豆属(Dumasia DC.)和假福王草属(Paraprenanthes C. C.Chang ex C. Shih)为香港的新记录属。以上的发现不仅丰富了香港的植物区系,而且表明保护残存植被非常重要,且极小种群的保护也值得特别关注。朱慧玲 刘金刚 张金龙 幸敬阳 杨永佳 Gunter A.FISCHER 2018广西植物2018,38,9:3
4Metal-organic framework derived multi-functionalized and co-doped TiO_(2)/C nanocomposites for excellent visible-light photocatalysis显示文摘Multi-functionalized and co-doped TiO_(2)/C nanocomposites were derived from the pyrolysis of Ti-MOFs at 800℃under different gaseous atmospheres and their photocatalytic performance were investigated.The gaseous atmosphere during pyrolysis plays a critical role in determining the structural,textural,optical and physicochemical properties of the derived TiO_(2)/C composites due to the synergistic effect of nitrogen-containing species,carboxylate and sulfur functionalized porous carbon as well as N/S co-doped TiO_(2)nanoparticles.All the Ti-MOFs derived TiO_(2)/C composites exclusively possess homogeneously distributed TiO_(2)nanoparticles in a functionalized disc-like porous carbon matrix and demonstrate much enhanced adsorption and photodegradation performance than commercial TiO_(2)under the same conditions.The adsorption of methylene blue(MB)in dark on these TiO_(2)/C composites are dominated with pseudo second-order kinetic model and the high adsorption capacity of MB in dark on composite TiO_(2)/C derived from MIL-125(Ti)in argon is due to its high surface area with predominant mesoporous carbon matrix in the composite.The composite N-O-TiO_(2)/C derived from NH2-MIL-125(Ti)in water vapor exhibited the highest photodegradation activity with 99.7%MB removal in 3 h under visible light due to the optimal anatase/rutile phasejunction,together with the formation of photoactive oxygen-rich N-O like interstitial/intraband states above the valence band of TiO_(2),as well as the presence of N-containing species and-OH/-COOH multi-functional groups with superhydrophilic nature of the composite.This simple one-step and easily modifiable approach can be further employed to modulate homogeneously dispersed multi-functionalized and co-doped metal oxide/carbon nanocomposites for various environment and energy-related applications.Mian Zahid Hussain Zhuxian Yang Ahmed M.E.Khalil Shahzad Hussain Saif Ullah Awan Quanli Jia Roland A.Fischer Yanqiu Zhu Yongde Xia 2022Journal of Materials Science & Technology2022,,6:3
5植物标本标签设计的原则及R程序包herblabel显示文摘植物标本是分类学、生态学和分子生物学最重要的凭证之一。标本的采集和鉴定信息需清晰、准确、美观地展示和保存于标本标签中,不能有歧义以及拼写错误。在标签的制作过程中,数据输入的方式要简单、直接,标签文件生成过程中最好能自动分析错误,且在打印之前要便于修改和调整。本文探讨了打印植物标本标签的若干原则以及注意事项,并介绍了用R语言编写的herblabel程序包生成植物标本标签以及鉴定标签的过程。herblabel程序包基于Darwin Core和CVH5.0数据交换标准,可快速批量生成几种样式的RTF标签,且标签简洁、美观,易于编辑。herblabel程序包具有检查地点完整程度,学名拼写和接受状态,科、属在APG等新系统下的对应关系等功能,可有效减少数据录入过程中产生的错误。此外,本程序包在打印标签时使用的是基于Darwin Core标准保存的标本数据库,不仅方便统计和管理,也可以直接用于全球生物多样性信息网络(GBIF)数据共享或者数字植物标本馆的建设。该程序包可显著提高植物标本馆标本制作、管理和信息录入的工作效率,减轻工作人员的负担,并在植物生物多样性编目中发挥重要作用。张金龙 朱慧玲 刘金刚 Gunter A.Fischer 2016生物多样性2016,24,12:2

16Long-term consumption of virgin coconut (Cocos nucifera) oil diet impairs learning and memory in CD1 mice显示文摘Objective:Virgin coconut oil(VCO)has been used in the management of dementia in Alzheimer’s disease(AD).Therefore,this research investigated the effect of long-term consumption of VCO diet on learning and memory in CD1 mice.Methods:Thirty male CD1 mice(divided into three groups,n=10)were fed with standard rodent chow(control),5%and 20%VCO diets(respectively)for 28 d.The Morris Water Maze(MWM)test was used to test the effect of VCO on visuo-spatial learning and memory,while the Novel Object Recognition Test(NORT)was used to measure short-and long-term recognition memory.Results:Learning performance of mice did not differ in the MWM.During the probe trial,duration in the retention quadrant and annulus crossings were lower(P<0.05)in the 5%and 20%VCO diet groups compared to the control diet group,showing that VCO impaired visuo-spatial memory.During the NORT,mice showed more total approaches in the 20%VCO diet group(P<0.05)compared to control and the 5%VCO diet groups during the short-term memory test.During the long-term memory retention test,the total approaches were also higher in the 20%VCO group compared to control and 5%VCO group(P>0.05).The discrimination index was also lower in the 20%VCO group compared to control and 5%VCO diet groups indicating impaired long-term cognitive memory in mice given 20%VCO diet.Histological examination of brains showed damage within the CA1 pyramidal cell layer of the hippocampus in the 20%VCO diet group,in line with the behavioural observations.Conclusion:Long-term consumption of virgin coconut oil diet impairs memory in mice.Sunday A.Bisong Clement O.Nku Olushola A.Sanya Sunday O.Ita Victor A.Fischer Favour E.Abuo 2020Chinese Herbal Medicines2020,12,4:0
