To create an efficient materials design workflow, a team of researchers at Tohoku University is suggesting not just one tool—but a whole toolbox that works together as a cohesive kit. The work is published in the journal Chemical Science.

This comprehensive system is called a "digital materials ecosystem" because it integrates multiple processes together instead of treating them as disconnected steps. For example, the ecosystem is capable of not only predicting how certain materials will react, but also orchestrating multi-step scientific workflows including searching for evidence, screening candidates, and deciding what to test next.

"The ecosystem frames materials discovery as a closed-loop, self-improving system," explains Distinguished Professor Hao Li (Advanced Institute for Materials Research (WPI-AIMR)).

Researchers at the Center for Computational Sciences, University of Tsukuba, have developed an accessible platform to overcome the limitations of conventional static docking simulations, offering new avenues for education, training, and reproducible research in molecular recognition and supramolecular chemistry. Their Distance-Guided Fully Dynamic Docking (DFDD) platform is a cloud-ready simulation framework that enables students and researchers to explore dynamic docking, visualize molecular binding in motion, and understand how host-guest crystal structures emerge from molecular interactions.

Chemical unicorn
In the journal Science Advances, scientists in Sweden and the U.S. report the first-ever direct observation of a type of short-lived molecule that has shaped decades of thinking in atmospheric chemistry, combustion research and biomedical science. "This compound is the equivalent of the Higgs boson for oxidation chemistry," says Barbara Nozière, professor of physical chemistry at KTH Royal Institute of Technology. "Its existence was assumed for decades but nobody had ever seen it."

Stronger hydrogels?
A study led by Northwestern University researchers has reported a way to observe hydrogel nano and microstructure while the hydrogel remains fully solvated....The material is orders of magnitude more rigid than previously believed, and theoretical models can be used together with this new information to better predict its mechanical behavior. Northwestern University Ph.D. candidate Nathan Rosenmann was first author on the paper, which was published in Nature Materials on March 11, 2026.

Metal
Now, however, researchers from the Institute of Physics of the Chinese Academy of Sciences, along with their collaborators from Zhejiang University, have realized electric-field control of magnetic states using a two-dimensional (2D) van der Waals material, while demonstrating intrinsic room-temperature (RT) multiferroicity with strong ME coupling.

The study is published in the journal Nature Materials.

LEDs
Light-emitting electrochemical cells (LECs) are simple, flexible, and low-cost thin-film devices that generate light from an electric current. Unlike conventional organic LEDs, LECs contain just a single active layer—an organic semiconductor blended with mobile ions—sandwiched between two electrodes. This structural simplicity makes them promising tools for next-generation light-emitting technologies.

Bacterial electricity
Rice University researcher Rafael Verduzco developed a safe bioelectronic sensor that allows for effective electronic communication even in liquid environments. The study was recently published in the journal Advanced Materials.

Photocatylist
MLIP calculations successfully identify suitable dopants for a novel photocatalytic material, report researchers from the Institute of Science Tokyo. As demonstrated in their study, published in the Journal of the American Chemical Society, a materials informatics approach could predict which ions can be stably introduced into orthorhombic Sn3O4, a promising and recently discovered photocatalytic tin oxide.

New carbon designs

In 2024, a team of UK researchers unveiled CrystaLLM: a Large Language Model (LLM) that can model crystal structures using text.
With this approach, the researchers discovered several allotropes with combinations of exotic properties that have never previously been observed. Among them is a superhard phase with a calculated hardness exceeding even that of diamond. Its dense sp3-dominant network makes it a potentially groundbreaking material for applications demanding extreme hardness.

On top of this already remarkable discovery, the team discovered a material whose thermal conductivity varies depending on the direction of heat flow, combined with an ultra-low shear stiffness—allowing different regions of the carbon lattice to reorient relative to each other when a shear force is applied.

"We also discovered an sp-sp2-sp3 hybridized phase of C12 phase containing 12 carbon atoms per unit cell, which uniquely combines metallic conductivity with a negative Poisson's ratio," Gao says. The latter property describes how the material counterintuitively expands in a direction perpendicular to the direction in which it is being stretched.

"Electronic structure calculations further show that certain yne-diamond phases are narrow-bandgap semiconductors suitable for infrared or thermoelectric applications."

Cracking
Understanding how a crack grows in metal requires simultaneously calculating the behavior of hundreds of billions of atoms: At the crack tip, where atomic bonds break, and in the surrounding volume of material, where the stress, driving the crack propagation, is distributed. For modern supercomputers, an accurate modeling of this process remains beyond reach. Researchers from the Skoltech Artificial Intelligence Center have proposed a solution, now published in the journal Computer Physics Communications.

In a publication in the Journal of the American Chemical Society, Hernández Sánchez and his team describe a way to enable pi interactions between dioxygen and a lanthanide metal called neodymium, enabling the creation of lanthanide-oxos.

Surfaces

a Würzburg-based research team from the Cluster of Excellence ctd.qmat has achieved the first experimental demonstration of KPZ behavior on 2D surfaces in space and time.

This was made possible by sophisticated materials engineering and a bold experimental approach: researchers injected polaritons—hybrid particles composed of light and matter—into the material. The results have been published in Science.

The question of how surfaces grow is one of the most fundamental problems in physics. In 1986, three physicists laid the foundation for a universal theory of growth with the Kardar–Parisi–Zhang (KPZ) equation—a framework with wide-ranging applications across physics, mathematics, biology, and computer science.

New Scientist profile on John Pendry, the father of the metamaterial invisibility cloak.

www.newscientist.com

The invisibility cloak inventor now has better tricks up his sleeve

John Pendry is known for creating an invisibility cloak. Twenty years on, he has used the same principles to fashion an even more powerful kind of metamaterial that can teach us about the wild frontiers of physics
www.newscientist.com www.newscientist.com

It's paywalled but if you hit reload and then stop quick enough you might get it. Of course you could subscribe.

Titbits:

Decades earlier, in the 1960s, Veselago had imagined materials that would refract light in reverse, causing a simple slab to focus rather than disperse light. It was long assumed to be impossible, but Pendry worked out how to coax light into obeying the strange mathematical rules that Veselago had sketched out.

...

In fact, metamaterials appear to be finally taking off. Many have reached commercial maturity, with some of the most striking advances appearing in so-called metalenses. Rather than bending light through curved glass, metalenses shape light directly using surfaces patterned with dense forests of nanoscale structures, each acting like a tiny antenna. The result is a paper-thin lens, just micrometres thick, that can outperform traditional optics. Instead of stacking heavy glass elements inside a camera, a single flat layer can do the job. “One application is to put them in these drones,” says Pendry. “You can have tiny, tiny drones that still have very, very good optics, because they have these extremely light lenses.” Smartphones and virtual-reality headsets can also now carry high-performance optical systems without the usual weight penalty.

...

Myhrvold thinks metamaterials could change that, and he is developing lidar systems that steer laser beams electronically, with no moving parts at all.

...

Some years ago, Pendry began to wonder if there could be such a thing as temporal metamaterials, which would control how light moves in time, too... The upshot of this is that a temporal metamaterial can inject energy into a wave, or drain it away, shifting its frequency. Red light becomes blue. Microwaves become infrared. They are a kind of philosopher’s stone that can transmute one type of electromagnetic wave into another.

...

In 2023, Pendry calculated what would happen if you built a material whose internal pattern shifts in time so that it appears to move at almost the speed of light. Under those conditions, the mathematics produces points that light cannot cross – in other words, an analogue of a black hole’s event horizon. He says that an experimental realisation of his ideas could provide a new way to study black holes in a lab.

...

...Casimir effect. Place two metal plates a few nanometres apart in a vacuum and, counterintuitively, they will be pushed together. The effect arises thanks to the fluctuations of quantum fields in a vacuum. But Pendry has pointed out that changing a material’s electromagnetic properties in time may produce a dynamic version of the same phenomenon, where this subtle pressure can be dialled up to produce a never-before-seen quantum analogue of friction.
