| 1 | CNTs和Nb纳米颗粒提高电力传输线用放电等离子体烧结铝合金的摩擦和热性能(英文)显示文摘用放电等离子体烧结法(SPS)制备铝合金,以碳纳米管(CNTs)和Nb纳米颗粒作为增强相,提高合金的摩擦性能和热性能。SPS工艺参数为:630℃、30 MPa、10 min和200℃/min。而且,以钢球为对磨件,采用球-盘式摩擦试验机对样品进行摩擦学试验。用热重分析仪(TGA)和激光导热仪(LFA)进行热性能分析。结果表明,分别添加8 wt.%的CNTs和Nb纳米颗粒使复合材料的摩擦因数(COF)降低79%。磨损量和磨损率也降低23%,且复合材料的热导率提高44%。摩擦性能的改善是由于CNTs的加入导致材料表面形成C薄膜,以及由于Nb纳米粉末的加入而生成起保护作用的Nb2O5。导热性能的改善是由于Nb的晶粒细化作用和CNTs的高导热性。因此,这些结果表明,Al-CNTs-Nb复合材料是高压输电导线用的坚固材料,能够减小下垂并保证材料的使用寿命。 | Chika O.UJAH Patricia POPOOLA Olawale POPOOLA Victor AIGBODION Philip OLADIJO | 2020 | Transactions of Nonferrous Metals Society of China2020，30，2： | 1 |
| 2 | Pathways for Sustainable Utilization of Waste Chicken Eggshell显示文摘Chicken eggshell is one of the most common wastes generated from households,restaurants and other food processing outlets.Waste Chicken Eggshells(WCES)also constitutes an environmental nuisance and ends up discarded at dumping site with no consideration of further usage.The main constituent of WCES is calcium carbonate from which calcium or calcium oxide can be extracted for various applications.This current effort reviews recently published literature on the diverse applications of WCES.The considered utilization avenues include catalysts for biofuel production,construction industry,wastewater purification,industrial sector,food industry,medical,and agricultural applications.The specific areas of application apart from the transesterification reactions include cement additives and replacement in concrete,asphalt binder,adsorbent of metals and dyes,production of hydroxyapatite,food supplement and fortification,dentistry,therapeutics,bone formation,drug delivery,poultry feeds as well as organic fertilizer.For most of the identified applications,the WCES is subjected to pretreatment and other modification techniques before utilization.The conversion of WCES to valuable products is a cost-effective,safe,environmentally friendly,non-toxic and viable means of waste disposal and utilization.More investigations are needed to further explore the benefits derivable from this bioresource. | Omojola Awogbemi Daramy Vandi Von Kallon Victor Sunday Aigbodion | 2022 | Journal of Renewable Materials2022，10，8： | 0 |
