1三维炭纤维预型体上烷烃气的催化炭沉积(英文)显示文摘研究了承载镍催化剂的三维(3D)炭纤维预型体,在含氢或无氢条件下,乙烷和合成天然气在其上面化学气相沉积形成的炭沉积率和碳纳米构结物。观察了炭沉积所获石墨纳米纤维、碳纳米管和石墨碳壳,得知沉积碳的纳米结构取决于沉积温度和碳源气组成。在650℃~800℃温间,总沉积时程直至12h,研究了烃类碳源气在氢气平衡下,从体积分数100%到20%变化情况。经Ni(NO3)2-6H2O甲醇溶液浸渍的3D炭纤维预型体在炭沉积前因溶液分解可还原出Ni。采用质量变化测定法、热谱-质谱分析仪、SEM、TEM和XRD对样品进行表征。结果表明:纤维状炭与囊包炭的比率随氢气含量的增加而增加,随反应温度的增高而减少。出乎意料的是,氢气的添加并不延长催化剂的寿命。该工艺过程对炭/炭复合材料的制备展示出良好的潜力。Matthew J Thornton Gavin S Walker 2009新型炭材料2009,24,3:2
2限域在介孔材料中的氨硼烷的催化脱氢性能和化学储氢性能(英文)显示文摘报道了同时采用催化剂和限域基体对氨硼烷(BH_3NH_3)脱氢性能的影响.结果发现,非贵金属催化剂和孔状限域基体能显著改变氨硼烷的储氢性能.填充在介孔二氧化硅中含Co催化剂的氨硼烷在75℃或90℃能释放出4%或9%纯氢,进一步用锂修饰介孔二氧化硅可使氨硼烷脱氢速度更快,但产生氢气、氨气和二硼烷的混合气.氨硼烷热分解活化能的降低导致填充在介孔二氧化硅中含催化剂的氨硼烷具有较快的动力学和热力学行为.夏勇德 WALKER Gavin S 朱艳秋 2012复旦学报(自然科学版)2012,51,5:2

14Technical Design for Holistic Wireless Communication in Smart Buildings显示文摘This paper presents the design of a wireless building monitoring network implemented at the University of Nottingham's Creative Energy Homes test site.The network is installed in seven smart buildings with the aim of holistically collecting energy data.Data will be used to inform a central control algorithm to optimise the energy flows between buildings,in turn promoting the smart cities concept.Sensors and meters measuring temperature,humidity,CO_2,heat energy,power,and stratified tank temperature are described.Furthermore,the communication protocols utilised are also discussed,which include wireless MBus and EnOcean.This paper also covers the methods used for ensuring the reliability of data signals and the system controls.Sean Rhys Jones Mark Gillott Rabah Boukhanouf Gavin Walker David Tetlow 2018Transactions of Nanjing University of Aeronautics and Astronautics2018,35,S1:0
