Many cutting-edge technologies rely on molecules that can be switched on and off with light, but making them respond efficiently to visible light without losing stability has long been a challenge. Researchers at Tohoku University, working with Heinrich Heine University Düsseldorf, solved this by attaching a "molecular antenna" that captures visible light and funnels the energy directly into the photoswitch, achieving some of the highest visible-light sensitivities ever reported.

Finding better materials to store hydrogen safely and efficiently is key to clean energy, but AI models trained on incomplete data can recommend candidates that don't actually work in practice. An international team led by Tohoku University, drawing on insight from 69 researchers, has proposed a "physics-aware" framework that combines thermodynamic constraints, reproducible data, and real experimental feedback to make AI-guided materials discovery more reliable. The roadmap could help accelerate the search for practical hydrogen storage solutions to support future clean-energy systems.

Scientists have turned a common blue pigment into a powerful tool for fighting climate change. Researchers at Tohoku University, Hokkaido University, and AZUL Energy created a copper phthalocyanine catalyst that converts carbon dioxide directly into methane fuel in a single step, reaching nearly 80% efficiency and sustaining performance for 80+ hours. The breakthrough could make carbon recycling more practical and scalable using an inexpensive, readily available material.

Researchers at the University of Osaka discovered a simple, rigid aromatic hydrocarbon that breaks the usual rule. Under pressure, its crystals grow 1.7 times brighter and shift color from light blue to yellow, with a record-high sensitivity of 37.4 nm/GPa, nearly double the previous best. An elongated, uniformly slender molecular shape was the key, offering a new design principle for pressure-responsive materials without complex flexible frameworks.

Researchers at Tohoku University have combined multiple tools to create an automated, self-improving AI workflow that may improve our search for polymer material candidates so that it is less expensive, less costly, and more environmentally friendly.

Researchers led by the University of Osaka developed a reusable light-responsive adhesive that switches adhesion at the interface instead of weakening the whole material. UV-A light reduces interfacial adhesion, enabling selective peeling without observable residue, while UV-C light restores adhesion. The response was retained through repeated cycles without solvent processing. The approach could simplify disassembly, repair, and recycling of electronics, vehicles, and semiconductor components, supporting more circular manufacturing across industries.

A study in budding yeast suggests that changes in membrane lipids trigger a braking system that slows internal protein transport when the endoplasmic reticulum comes under stress, comparable to modern logistics networks where shipments are slowed when distribution hubs are under stress.

Researchers at the University of Osaka used cyclic PPS manufacturing by-products as movable molecular crosslinks in biodegradable PCL. Medium-sized c [7] PS rings approximately doubled toughness while slowing enzymatic degradation, whereas larger c [9] PS rings accelerated degradation to no residual film mass after 48 hours. The findings identify molecular ring size as a design parameter for tuning material lifetime while also offering a waste-to-value route toward more sustainable polymer systems with programmable properties.

Instead of producing graphene at temperatures as high as 900°C, researchers at Tohoku University found a way to lower this to 300 °C. Even better, the material used to achieve this can be easily obtained from industrial waste.

Researchers from the University of Osaka found that amyloid formation is promoted by a combination of shear stress and constrained geometry in an in vitro model of amyloidogenic light chain disease. Applying mechanical agitation or pressure, as well as disaggregating agents, effectively removed amyloid deposits. These findings provide a novel framework for understanding amyloid deposition in organs.

Researchers redesigned C-shaped organic dyes so they lose less energy while emitting near 1000 nanometres. In an OLED, the optimized design reached an external quantum efficiency of 3.56% at 995 nanometres.

Researchers at the University of Osaka developed a catalyst that uses ultrasonic vibration to convert CO2 into CO. By modifying the catalyst with a metal–organic framework (MOF) incorporating isolated copper atoms, the catalyst is designed to concentrate CO2 near copper reaction sites and make better use of piezo-induced charges generated by vibration. It achieved a CO production rate of 114 μmol g-1 h-1, nearly five times that of pristine BaTiO3. The findings provide a new strategy for using mechanical energy to support more efficient carbon recycling.

Researchers at the University of Osaka developed chiral hole-transport materials that selectively conduct electrons according to spin. Across three classes of materials, molecular handedness consistently determined the direction of spin polarization. The homochiral material also showed nearly threefold higher hole mobility and improved charge extraction and surface passivation in perovskite solar cells, highlighting new possibilities for controlling spin, charge transport, and interfaces through molecular design.

As solid-state electrolyte research grows, so does the amount of data. The problem is that much of it remains scattered across the literature. That is where researchers at WPI-AIMR, Tohoku University, come in — with DigBat, a new platform designed to bring this information together and help map the growing landscape of solid-state electrolyte research. By connecting data from across the field, DigBat can help researchers see relationships more clearly and point toward promising directions for future battery materials research.

Hydrogen may be a clean fuel, but not all hydrogen is green. Most H₂ is still produced from fossil fuels, while storing and transporting it remain costly and technically challenging. For hydrogen to truly live up to its green promise, we need cleaner and less costly ways to produce and store it. Looking for a more sustainable way forward, researchers at Tohoku University have developed a potential solution. Their new recyclable system uses baker’s yeast to store hydrogen directly in organic molecules and abundant, inexpensive iron ions to release it when needed.

Triple-negative breast cancer (TNBC) accounts for roughly 15–20% of all breast cancer cases and is difficult to treat. Patients are often left with chemotherapy as their only treatment option. This is because TNBC tumors contain a large number of T cells that suppress the immune system. Yet researchers from Tohoku University have come up with a three-pronged approach to overcome this problem.

Researchers from the University of Osaka have developed a new class of chiral semiconducting polymers that can generate highly spin-polarized electrical currents.

This transformation enables the upgrading of structurally simple α-silyl alcohols into functionalized derivatives that are difficult to access by conventional methods. The key to this success lies in utilizing a finely tuned phosphonium ylide catalyst in combination with an organophotoredox catalyst under visible-light irradiation.

Researchers from the University of Osaka, Gunma University and Kyushu University created lipid mimic molecules that form “island”-like groups called lipid domains in artificial lipid membranes. The domains are thermally stable because the propellor-shaped moiety of the lipid mimic molecules interlock and the surrounding lipids fit into the spaces between. This new method of forming domains may allow artificial lipid membrane materials to be created for catalysis, capturing molecules, and drug delivery.
