Abstract
The effect of thiourea on the nano-mechanical and chemical properties of Ni-P foil was studied to develop a high performance Ni-P deposit for automobile and machinery parts. The Ni-P deposit was prepared by electroforming in a modified sulphate bath with different amounts of thiourea. Chemical analysis of the electrodeposited Ni-P..... More

Abstract
The effects of heat treatment conditions on the mechanical properties and energy absorption capacity of 7003 (Al-6Zn-0.6Mg) aluminum alloy were studied. The extruded material was heat treated at various temperatures to prepare annealed or aged specimens. Tensile tests, hardness measurements, electron backscatter diffraction characterizations, and differential scanning calorimeter analyses were..... More

Abstract
Studies of effective furnace cooling technology and refractory materials have extended the lifetime of a blast furnace to more than 15 years. On the other hand, the replacement of refractories in the blast furnace results in considerable cost and time loss for stopping the blast furnace operation. Various kinds of..... More

Abstract
The ability to form high quality nano-/micro- patterns is very important for the nanofabrication of high-density electronic devices. However, remaining challenges have yet to be resolved, including low quality roughness, low pattern resolution, and the highly complex process. In this study, we suggest a novel and simple method for creating..... More

Abstract
Laser surface heat treatment and laser nitriding processes were applied using selective surface modification techniques to investigate phase transformation, microstructural evolution, and surface hardening behaviors for two types of plastic injection mold steels, AISI 1045 and P21. During laser surface heat treatment, a 245% hardness increase compared to that of..... More

Abstract
Electroplating has many economic advantages in producing copper foils. The easiest way to manufacture electroplated copper foil with various properties is to add appropriate additives. This study evaluated the surface properties, mechanical and electrical properties of copper foil electroplated in electrolytes containing the leveler JGB (Janus Green B). When the..... More

Abstract
In this study, we investigated the morphological, crystal structural, electronic structural, and electrocatalytic properties of the inverse spinel structured copper cobalt oxide (Cu_0.72Co_2.28O₄) catalysts. The materials were prepared by coprecipitation using various copper and cobalt precursors, and subsequent oxidation treatment. Electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Brunauer Emmett..... More

Abstract
The photovoltaic properties of TiO₂/ZrO₂ double electron transport layered perovskite solar cells were investigated based on the ZrO₂ layer thickness. Samples were fabricated with a glass/FTO/TiO₂/ZrO₂/ perovskite structure. The TiO2/ZrO₂ layer thickness ratio was confirmed to be 264/0, 228/168, 228/204, 270/242, and 282/288 nm, respectively, using an electron probe microanalyzer...... More

Abstract
ZnO nanorods are one of the most studied materials because it can be facilely grown on a wide range of substrates at low temperature. ZnO exhibits piezoelectricity as well as semiconducting properties, and hence is applicable to piezoelectric nanogenerators and sensors. In the present work, the effect of ZnO nanorods’..... More
