Left: Atomic force microscopy images of Mo-BiVO4 thin films before degradation (top-left) and after degradation (bottom-left); corrosion causes the grains of the material to disconnect from each other. Right: X-ray...

IKEN physicists have initiated unusual sound waves in a flake using ultrashort pulses of laser light and then created videos of their movement using electron microscopy. This advance should help...

A team of researchers led by Osaka University discovers “microtube implosion,” a novel mechanism that demonstrates the generation of megatesla-order magnetic fields. Magnetic fields are used in various areas of...

Due to the continuing progress in miniaturization of silicon microelectronic and photonic devices, the cooling of device structures is increasingly challenging. Conventional heat transport in bulk materials is dominated by...

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond...
