Innovative Catalyst: Transforming Fuel Cells for Sustainable Energy Solutions

This groundbreaking catalyst revolutionizes fuel cell technology by substituting the O2- anion within mayenite C12A7 with a halogen element or electron. This strategic modification results in exceptional capabilities for both the hydrogen oxidation reaction (HOR) and the oxygen reduction reaction (ORR), rivaling platinum efficiency. Synthesized from cost-effective materials, it emerges as a promising platinum substitute, particularly in polymer electrolyte fuel cells (PEFCs). The catalyst's unique replacement of the O2- anion enhances its catalytic prowess, achieving dual capability in HOR and ORR. Positioned as a strong competitor against platinum, it mitigates problems associated with crystalline surfaces, a significant advancement for fuel cell applications.

Memorism Processor (Search-Less information Detector)

Memorism Processors are processors that takes over “processing that requires data detection”, which conventional processors such as CPU and GPU struggle with.
The division of tasks between conventional processors and Memorism Processors enables a “renewal of computers that literally modernizes the information processing industry”, transforming them into user and environmentally friendly computers.
Current information processing, since current computers (von Neumann-type computers) were born in 1946, CPUs, memory, and peripherals have undergone major performance improvements, but the systems have not evolved at all.
This generated the following problems that we have today:Future information processing society In the future, the information processing industry will not only need to adapt to a low-carbon society, but also make good use of technologies such as AI, IoT, and Big Data. As the semiconductor miniaturization technology known by Moore’s law approaches its limit, enhancing the performance of CPUs and GPUs will become increasingly more difficult and will require innovations that are not tied to past common sense ideas and values concerning information processing.

MEMS infrared photodetector

MEMS infrared photodetector

In Kan Laboratory at the University of Electro-Communications, we are conducting research on unique MEMS optical sensors and devices by fabricating micro- to nano-sized metal diffraction gratings and pillar structures on silicon. Normally, silicon alone does not have sensitivity to infrared light, but by utilizing the Schottky barrier formed at the interface between silicon and metal, it becomes possible to electrically detect infrared light with silicon. By absorbing externally incident light with diffraction gratings or pillar structures formed through MEMS processes, it is also possible to selectively detect specific wavelengths or polarizations of light. By utilizing these features, it is possible to construct infrared light detectors using silicon-based devices, as well as to develop spectroscopic sensors, gas sensors, and chemical sensors. Furthermore, by using silicon as the substrate material, it has the advantage of being able to utilize existing semiconductor manufacturing processes and leverage the legacy of semiconductors. This is a highly efficient method in terms of mass production and system integration. In this way, Kan Laboratory is utilizing unique MEMS principles to advance research on ultra-compact, cost-effective optical sensors with simplified manufacturing processes.

Research on three-dimensional information analysis technology to elucidate the plant growth mechanism

In this research, by analyzing the three-dimensional "shape" of plants, we aim to clarify the plant growth mechanism for stable harvesting of crops and improvement of cultivation technology.
The appearance of plants, such as the size of fruits and leaves, and the length and thickness of branches, changes depending on various environmental factors such as hours of sunshine, temperature, and soil moisture content, even if they have the same genetic information. Clarifying the relationship between the shape of plants and environmental factors will help improve cultivation techniques for crops.
Therefore, in this research, we used image engineering technology to construct a system that can reproduce three-dimensional "shapes" from multiple plant photographs in order to accurately measure the appearance of plants. By using this system, it is now possible to clarify the three-dimensional characteristics of the plant growth, such as the direction and degree of bending of branches, which could not be known by two-dimensional analysis using photographs.

AkaSuke™: A Highly bright luminescence substrate for in vivo bioluminescence imaging (BLI)

We have succeeded in developing a new labeling material for deep in vivo visualization: luminescence substrate “AkaSuke™”.
AkaSuke™” has both near-infrared emission characteristics suitable for deep in vivo visualization and water solubility for in vivo administration. In addition, “AkaSuke™” has achieved a 6 times-fold increase in brightness compared to D-luciferin.
Focusing on the reaction mechanism between the luminescence substrate (firefly luciferin) and the luminescent enzyme (firefly luciferase) involved in the firefly luminescence, we have realized multicolor luminescence materials covering all visible light and have developed firefly bioluminescence labeling materials by organic synthesis of a number of luciferin derivatives that emit in the near-infrared region, among others.
In this study, we have applied these findings to realize high luminescence by using natural enzyme "Fluc".

TokeOni ® : the new luciferin analogue for innovative bioluminescence imaging

In vivo optical imaging is a technology that allows visualization of the inside of an animal's body while it is still alive by illuminating only specific cells (e.g., cancer).
We have been working to develop new materials based on luciferin, a bioluminescent substance found in fireflies.
Based on this research, we have successfully synthesized a luminescence substrate with a luminescence peak in the window region of the living body (650 nm to 900 nm). This makes it possible to observe living organisms by making them glow while they are alive and enables imaging down to a depth of 5 to 6 cm from the epidermis.

Furthermore, Aka-BLI, a combination of Tokeoni optimized mutant “AkaLuc” and Tokeoni, enables quantitative observation of a small number of cells that have been difficult to detect.
In addition, Aka-BLI can be used to quantitatively observe neurons in the brain. Aka-BLI is 1000 times stronger than green-BLI, which combines firefly luciferin and wild-type luciferase, and also successfully used for imaging of marmoset striatum.
