This timely review focuses on the synthesis of zinc stannate (zinc tin oxide: ZTO) nanostructures by the hydrothermal method, as well as the physical properties and applications of different zinc stannate nanostructures in solar cells, gas sensors, and photocatalysts.

A critical review of the current status and future prospects of new computing architectures based on ‘atomic switches’ fabricated by controlling the movement of cationic ions during solid electrochemical reactions.

Toyohashi Tech researchers develop an innovative infrared photodetector exploiting ‘plasmon resonance’ at the surface of gold nanorods. This technology shows potential as the basis for the development of high efficiency infra-red photodetectors for optical communications systems.

The way that humans perceive each other is strongly affected by the configuration, contour, and complexion of faces. Researchers from Toyohashi Tech report the importance of facial colour on neural responses underlying perception.

Controlling the physical properties of the surfaces of materials, such as metals, is critical for industrial applications ranging non-stick frying pans to the fuselage of aircraft.

Silicon-based semiconductor devices dominate the microelectronics industry and are used for the fabrication of high density integrated circuits comprising of memory and processing devices. However, silicon has an indirect band gap, which severely limits its use for fabricating photonic devices such as light emitting diodes (LEDs) and lasers.

Microactuators are critical components for industrial applications such as MEMS, micro-medical devices, and microrobotics. However, the fabrication of increasingly sophisticated, millimeter sized microactuators is complicated and proving to be a challenge.
