Abstract
This article details how effectively dicing damage of silicon wafers can be mechanically minimized by appropriate laser-induced groove formation prior to wafer separation. Various laser dicing factors, such as the laser-control power, the scan rate and the scan number of the laser beam, were estimated to determine the optimum groove..... More

Abstract
In this study, the microstructure-controlled Zn interlayers were synthesized to improve the adhesion strength of Zn/Zn-Mg double layer coatings. The coating chamber temperature and working pressure were controlled based on the Structure Zone Model principles, to obtain a dense columnar microstructure in the Zn interlayer. By controlling the coating chamber..... More

Abstract
Al₂O₃ has a high Young’s modulus (380 GPa), a low density (3.98 g· cm^-3), good high-temperature mechanical properties, biocompatibility and excellent oxidation resistance. Al₂O₃ has been used for automotive, aerospace, bio-materials and various industrial applications. Despite its various merits, the low fracture toughness of the material below the brittle-ductile transition..... More

Abstract
Resistance Element Welding (REW) is a novel processing technology developed to join dissimilar materials such as aluminum and steel. It uses an auxiliary steel rivet (element) inserted into an aluminum sheet that forms a resistance spot weld with the steel sheet, and the aluminum work piece is mechanically joined by..... More

Abstract
Evaluation of electrode degradation in resistance spot welding of 1180TRIP steel was carried out through an electrode life test, and weldability testing was performed by the measurement of the nugget size, the peak load analysis and the measurement of the electrode tip size at 30 intervals. Analysis of the change..... More

Abstract
A large amount of waste nickel-cadmium batteries are being produced, and various studies have been conducted to recover the valuable metals contained in the batteries. Solvent extraction is mainly used to recover nickel and cadmium, but that method has economic and environmental problems. In this study, to solve these problems,..... More

Abstract
To attain high life standards, it is important to develop high-performance non-toxic gas sensors for public safety, environmental pollutant control, industrial processes, etc. Because reports on single element semiconductor-coated semiconducting metal oxides for sensing applications are rare, we synthesized SnO₂ nanowires and coated them with a 5 nm-thick or 10.....

Abstract
With the increased use of diverse electronics in the high frequency spectrum, high-performance absorbing and shielding materials are needed to ensure electromagnetic compatibility. Microwave absorbance of polymer composites of carbonyl iron powders with frequency selective surface (FSS) is investigated, focusing on the frequency of 5.8 GHz. Composite sheets were prepared.....

Abstract
A porous material can be regarded as a mixture of pores and solid phases, with effective thermal and mechanical properties that significantly differ from those of its base material. Material effective properties depend greatly on the structure and porosity. The effective properties of materials with different pore structures can vary..... More
