Landmine detection sensor

NEXT
PREV
Features

ALIS is a hand-held dual sensor system, which consists of a metal detector and a ground-penetrating radar (GPR). The most unique feature of ALIS is its visualiza- tion function of the metal detector and GPR. Operators can easily identify buried mines on the visualized image.
The full features of a state-of-the-art metal detector are available, for example the soil compensation function and the pinpointing capability. The GPR antennas are integrated into search head together with metal detector coils. The control unit holds all the electronics and a rechargeable battery. The color LCD display provides the survey results both from the metal detector and the GPR as images. Audio alert is also available for the metal detector indication.

Lethal effects of blue light on insects

NEXT
PREV
Features

We revealed the strong lethal effect of short-wavelength visible light (blue light: 400–500 nm) on insects. That is, we found that blue light irradiation by using a common light-emitting diode (LED) can kill the eggs, larvae, pupae, and adults of various orders of insects. Our findings will provide clean and safe pest-control technique as well as important information on the hazards of exposure to visible light.

Low temperature reforming of hydrocarbons using metal oxide nanoparticles synthesized by supercritical method

NEXT
PREV
Features

Our research group has succeeded in synthesizing various metal oxide nanoparticles with controlled size and exposure crystal planes by using organic modifiers under supercritical water conditions. The oxygen storage/release capacity of those materials in the low-temperature region is very high, and the reforming reaction of oxidative hydrocarbon proceeds at a significant rate. Besides, by combining the supercritical CO2 drying method, we have succeeded in forming a complex in which oxide nanoparticles are dispersed at a high concentration on the surface of the porous material, realizing both high oxygen storage/release capability and stability.

Targeted Application(s)/Industry

Low-temperature reforming reaction of biomass wastes, heavy oils, and methane. In the future, it is expected to be a technology that will lead to the construction of a low-carbon society, including CO2-free complete recycling of waste plastics.

Low-Temperature Synthesis of SiC Porous Bulk by Using Na

NEXT
PREV
Features

SiC ceramics is generally prepared at high temperature of 1200–2000ºC. We are able to prepare SiC at around 700ºC by using Na. Nano-powder of beta-type SiC was obtained from a mixture of Si and carbon powders in a Na melt. SiC porous ceramics were synthesized by heating mixtures of Si powder and carbon black at 700–900ºC in Na vapor. Biomorphic cellular SiC ceramics were formed by heating carbonized woods at 700 ºC with a Na-Si melt.

Targeted Application(s)/Industry

Applications : SiC porous ceramics are used in a wide range of applications, such as filters for gas or molten metal, diesel particle filters, catalysis supports, and light-weight structural materials.
Industry : Ceramic Engineering
