Sumitomo Chemical and Tokyo Institute カジノ シークレット 評判 Technology Create Next-Generation Environmental Technologies Using Strong Correlation Materials:
Two Innovative Results Published During the First Year カジノ シークレット 評判 Their Industry-Academia Collaboration Project
May. 23, 2024
Sumitomo Chemical Co., Ltd. and Tokyo Institute カジノ シークレット 評判 Technology, a national university corporation in Japan, established the Sumitomo Chemical Next-Generation Eco-Friendly Devices Collaborative Research Cluster in April 2023. Since then, they have been advancing research aimed at promoting the practical implementation カジノ シークレット 評判 strong correlation materials, which are expected to be one カジノ シークレット 評判 the key materials for next-generation quantum devices.
Recently, Sumitomo Chemical and Tokyo Institute カジノ シークレット 評判 Technology have successfully achieved two innovative results related to multiferroic materials*1, which are a type カジノ シークレット 評判 strong correlation materials.
- Succeeded in the miniaturization カジノ シークレット 評判 multiferroic materials, which has been technically challenging, marking a major step forward toward the implementation カジノ シークレット 評判 next-generation memories that operate with ultra-low power consumption
- Discovered high-efficiency phoカジノ シークレット 評判catalytic function in multiferroic materials, which could lead カジノ シークレット 評判 achieving a water purification system using sunlight that contributes カジノ シークレット 評判 reducing environmental impact
These results are expected to make a significant contribution to the development カジノ シークレット 評判 next-generation environmental technologies. Going forward, as a leading company in this field カジノ シークレット 評判 technology, Sumitomo Chemical will strive to achieve further results building on these achievements, and pursue their early implementation in society.
The group カジノ シークレット 評判 materials that have a strong electron-electron interaction is called strong correlation materials. They are expected to be utilized in next-generation memory devices that can operate with ultra-low power consumption, energy harvesting devices that efficiently convert ambient energy, such as light and heat, into electric energy, and environmentally-friendly water purification systems. Sumitomo Chemical believes that strong correlation materials are a next-generation essential technology that can contribute to both energy saving and generation. For this reason, since April 2023, the Company has been working on collaborative research projects with the University カジノ シークレット 評判 Tokyo, Tokyo Institute カジノ シークレット 評判 Technology, and RIKEN, through cross appointment*2.

In modern society, where information and communication technology is rapidly spreading, energy consumption by memory and computing elements is increasing, and low power consumption is a key requirement カジノ シークレット 評判 memory devices. Multiferroic materials, which have both strong ferromagnetism and strong ferroelectricity, are expected to be applied to magnetic memories that can operate with ultra-low power consumption. However, it has been known that it is extremely difficult to miniaturize multiferroic materials that are composed カジノ シークレット 評判 oxides. In this study, the teams succeeded in forming and integrating bismuth ferrite cobaltate, a multiferroic oxide, into nano-sized dots using the porous structure カジノ シークレット 評判 alumina prepared by applying current in an acidic solution. Furthermore, it was confirmed that each nanodot had a single polarization information, marking a significant step toward the realization カジノ シークレット 評判 next-generation high-density low-power magnetic memory.

Details:
As interest in the Sustainable Development Goals has been growing in recent years, there is demand for clean and highly efficient technology to purify the large amounts カジノ シークレット 評判 organic wastewater generated during the dyeing process カジノ シークレット 評判 textiles, such as denim. Photocatalytic technology has been attracting attention as a solution for this issue, but there are some challenges for its practical use. With conventional photocatalysts using titanium dioxide, the decomposition reaction カジノ シークレット 評判 organic substances by visible light (sunlight) does not progress sufficiently, and it is also difficult to recover catalysts efficiently. In this study, the team found that bismuth ferrite, a multiferroic material, supported with gold nanoparticles functions as a highly efficient visible-light photocatalyst, and succeeded in the high-efficiency decomposition カジノ シークレット 評判 organic dyes by visible light and catalyst recovery using magnets. This technology is expected to achieve a recyclable water purification system that uses solar light as a green energy.
