Publication Metadata only Properties of experimental copper-aluminiumnickel alloys for dental post-and-core applications(2014-01-01) Apiwat Rittapai; Somchai Urapepon; Julathep Kajornchaiyakul; Choltacha Harniratisai; Mahidol University; National Metal and Materials Technology Center (MTEC)(595.9 ± 14.2 MPa) was shown in the Cu-12Al-4Ni alloy. The tensile strength was increased as the both elements increased. Alloys with 3-6 wt% Al exhibited a small amount of 0.2% proof strength. Accordingly, the Cu-9Al-2Ni and Cu-9Al-4Ni alloys not only... copper alloys with variants of 3, 6, 9, 12 wt% Al and 0, 2, 4, 6 wt% Ni were prepared and casted. Their properties were tested and evaluated. The data of thermal, physical, and mechanical properties were analyzed using the two-way ANOVA and Tukey's testPublication Metadata only Hydrogen-free hydrogenation of furfural to furfuryl alcohol and 2-methylfuran over Ni and Co-promoted Cu/γ-Al2O3 catalysts(2021-04-01) Munsuree Kalong; Plaifa Hongmanorom; Sakhon Ratchahat; Wanida Koo-amornpattana; Kajornsak Faungnawakij; Suttichai Assabumrungrat; Atthapon Srifa; Sibudjing Kawi; Chulalongkorn University; Thailand National Nanotechnology Center; National University of Singapore; Mahidol Universityin comparison with the monometallic CuAl, NiAl, and CoAl catalysts. The XRD analysis confirmed the generation of Ni-Cu and Co-Cu alloys after the reduction in presence of H2. The interaction between Cu and Ni or Co resulted in a simplicity of the reduction...Catalytic transformation of furfural to furfuryl alcohol and 2-methylfuran without H2 supply toward transfer hydrogenation process using 2-propanol as a H2 source was systematically investigated over the bimetallic NiCuAl and CoCuAl catalystsItem Metadata only Development of Cu-Al-Ni alloy for dental post and core application(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Apiwat Rittapai; Somchai Urapepol; Widchaya Kanchanavasita; Kallaya Suputtamongkolaffordable to patients. Sixteen groups of experiment alloys, with varying proportions 0, 3, 6, 9 wt % Al and 0, 2, 4, 6 wt % Ni, were prepared and their properties were evaluated. As generated by the biocompatibility characteristic, the 6 wt % Ni series...Generally, the technique used for replacement of the tooth is "posts and cores". Noble and semi-precious dental alloys have numerous excellent properties, but they are expensive and unaffordable for lots of patients. The copper-aluminum-nickel alloy
