In this study, the viscosities of molten pure Sn, a Sn–Pb eutectic alloy, and Sn–Ag–Cu alloys, whose properties such as liquidus temperature were similar, were measured using an oscillating ... Read More

Among intelligent materials, shape memory polymers (SMPs) exhibit significant changes in their Young’s moduli near the glass transition temperature (Tg), demonstrating unique properties such as ... Read More

The thermal conductivities of mesogenic epoxy (ME) resin films were evaluated by thermal microscopy (TM) based on periodic heating thermoreflectance. A three-layer model, consisting of a glass la ... Read More

We describe the strength and fracture of Si wafers instantaneously bonded by exothermic reaction in an Al/Ni multilayer film. The Al/Ni multilayer film deposited by dual-source direct current (DC ... Read More

In this paper, the differences in mechanical properties and fracture behavior between single-walled (SW), bundled, and yarned carbon nanotubes (CNTs) are described. The three types of CNTs are su ... Read More

In this study, targeting applications in flexible electronic devices, we developed and evaluated a capacitive humidity sensor with high sensitivity and excellent linearity, employing a polyimide ... Read More

In this study, Al/Ni multilayer powders fabricated by cold rolling were subjected to heat treatment to investigate the effects of the change in microstructure on their exothermic reaction charact ... Read More

A noncontact temperature measurement system based on thermoreflectance (TR) with a high signal-to-noise ratio (SNR) without temperature modulation was developed and optimized for responsiveness t ... Read More

By constructing a multi-orbital tight-binding model using a minimal basis of maximally localized Wannier functions (MLWFs) generated from first-principles electronic band structures, we obtained ... Read More
