An AuNPs/Mesoporous NiO/Nickel Foam Nanocomposite as a Miniaturized Electrode for Heavy Metal Detection Article

Boyuan Xue, Qian Yang, Kaidong Xia, Zhihong Li, George Y. Chen, Dayi Zhang, Xiaohong Zhou

Engineering 2023, Volume 27, Issue 8,   Pages 199-208 doi: 10.1016/j.eng.2022.06.005

Abstract: We also propose a facile in situ hydrothermal calcination method to directly grow binder-free mesoporousNiO on a three-dimensional nickel foam, which is then electrochemically seeded with gold nanoparticlesThe meticulous design of a low-barrier Ohmic contact between mesoporous NiO and AuNPs facilitates target-mediatednanochannel-confined electron transfer within mesoporous NiO.

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 4,   Pages 534-545 doi: 10.1007/s11705-019-1821-4

Abstract: In this paper, a NiO/CeO catalyst with high catalytic performance in methane combustion was synthesizedThe incorporation of NiO was found to enhance the concentration of oxygen vacancies, as well as the activityThe presence of CeO prevented the aggregation of NiO, enhanced reduction by NiO, and provided more oxygenkinetics study indicated that the reaction order was about 1.07 for CH and about 0.10 for O over the NiO

Methane partial oxidation over NiO-MgO/Ce

Piyawat PUE-ON, Vissanu MEEYOO, Thirasak RIRKSOMBOOON

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 3,   Pages 289-296 doi: 10.1007/s11705-013-1345-2

Abstract: In order to find suitable catalysts that prevent the carbon deposition, NiO-MgO/Ce Zr O (CZO) supportedThis is because the Ni surface was partially covered with MgO, and the strong interaction between NiOand NiMgO over CZO support led to the difficulty in reducing NiO to active Ni and thus less catalytic

Mechanical properties characterization of different types of masonry infill walls

André FURTADO, Hugo RODRIGUES, António ARÊDE, Humberto VARUM

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 2,   Pages 411-434 doi: 10.1007/s11709-019-0602-y

Abstract: It is remarkable, the recent advances concerning the development of numerical modeling frameworks to simulate the infill panels’ seismic behavior. However, there is a lack of experimental data of their mechanical properties, which are of full importance to calibrate the numerical models. The primary objective of this paper is to present an extensive experimental campaign of mechanical characterization tests of infill masonry walls made with three different types of masonry units: lightweight vertical hollow concrete blocks and hollow clay bricks. Four different types of experimental tests were carried out, namely: compression strength tests, diagonal tensile strength tests, and flexural strength tests parallel and perpendicular to the horizontal bed joints. A total amount of 80 tests were carried out and are reported in the present paper. The second objective of this study was to compare the mechanical properties of as-built and existing infill walls. The results presented and discussed herein, will be in terms of strain-stress curves and damages observed within the tests. It was observed a fragile behavior in the panels made with hollow clay horizontal bricks, without propagation of cracks. The plaster increased the flexural strength by 57%.
