      • Zigbee-based Intelligent Home Furnishing

        Huang Jinhui,Xue ZiYu,Xu Xu,Tian Siyang 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.1

        With the constantly emerging of the high-tech, Household life of intelligent, network, digitization has become a research direction in the field of Internet of things. Against this background, this paper puts forward a set of intelligent household iot system based on ZigBee architecture design. The design scheme can be connected to various devices in the family, In order to realize people and equipment, equipment and equipment between "communication", Greatly convenient people's home life. Because the ZigBee module has many advantages such as save electricity, small volume, low cost .Based on ZigBee smart home system has great research value, and is a good way to promote the speed of the Internet of things into our life, let people know well to the role of the Internet of things and it is convenient for our life.

        A novel monitoring system for fatigue crack length of compact tensile specimen in liquid lead-bismuth eutectic

        Xue Baoquan,Tan Jibo,Wu Xinqiang,Zhang Ziyu,Wang Xiang 한국원자력학회 2024 Nuclear Engineering and Technology Vol.56 No.5

        Fatigue strength of the structural materials of lead-cooled fast reactors (LFRs) and accelerator-driven systems (ADS) may be degraded in liquid metal (Lead or lead-bismuth eutectic (LBE)) environments. The fatigue crack growth (FCG) data of structural materials in liquid LBE are necessary for damage tolerance design, safety assessment and life management of key equipment. A novel monitoring system for fatigue crack length was designed on the compliance method and the monitor technology of crack opening displacement (COD) of CT specimens by the linear variable differential transformers (LVDT) system. It can be used to predict the crack length by monitoring the COD of CT specimens in harsh high-temperature liquid LBE using a LVDT system. The prediction accuracy of this system was verified by FCG experiments in room temperature air and liquid LBE at 150, 250 and 350 ◦C. The first results obtained in the FCG test for T91 steel in liquid LBE at 350 ◦C are presented.

        Facile synthesis of AgPt nano-pompons for efficient methanol oxidation: Morphology control and DFT study on stability enhancement

        Tao Shao,Dehong Bai,Mingzhu Qiu,Yu Li,Qiankun Zhang,Ziyu Xue,Shijie He,Dongxia Zhang,Xibin Zhou 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.108 No.-

        Facile synthesis of more dendritic and uniform Pt-based nanostructures with carbon materials couldgreatly reduce cost and increase Pt utilization for methanol oxidation reaction (MOR) in direct methanolfuel cell (DMFC). This study reports a novel one-pot method to fabricate AgPt nano-pompons (AgPt NPs)with the guidance of N-GQDs through AA reduce the precursor of Ag and Pt. Morphology characterizationdescribes N-GQDs as morphology guiding and dispersing agents to regulate the dendrite formation ofnano-pompons. Under the optimized conditions, the AgPt NPs (Ag1Pt2) display above 11 times improvementin electrocatalytic activity and higher stability for the MOR compared with Pt/C catalysts. Densityfunction theory (DFT) studies prove that the introduction of Ag can greatly enhance the adsorption of COon Pt and promote the transformation of CO to COOH. The facile synthetic method and excellent MORperformance endow AgPt NPs with great application prospect in DMFCs as an anode catalyst.
