Interest in die-attach materials with high thermostability has been stimulated by the high junction temperature of power semiconductors. Sintered Ag nanoparticle bonding is the most attractive candidate for use as solder because of its high melting p

It is noted that utilization of ASEAN Free Trade Agreements (FTAs) is low by international standards. In order to clarify the reasons for such low utilization, this paper investigates what kinds of Japanese affiliates in ASEAN are more likely to use

Production networks have been extensively developed in East Asia. Previous studies on production networks used international trade data or input–output tables, but such aggregate data cannot explain how the networks actually operate. With the aim o

The high-temperature deformation of dense nano-sized Ca-α SiAlON and submicron- sized β-SiAlON polycrystals were investigated by compression tests. These polycrystals were fabricated from Ca-α SiAlON and β-SiAlON nano powders respectively, and co

A Ca-α SiAlON nanoceramic was fabricated from Ca0.8Si9.6Al2.4O0.8N15.2 nanopowder without using any sintering additive. The flow stress of the SiAlON nanoceramic, which contained almost no glass phase, was higher than that of liquid phase sintered S

β-SiAlON nanoceramics were fabricated from β-SiAlON nano powder using the spark-plasma sintering (SPS) technique. The β-SiAlON nanopowder (Si4Al2O2N6) was synthesized from a mixture of SiO2 (QS-102, Tokuyama Co., Japan), AlOOH (Tomita, Japan) and
