Conical intersections are crucial molecular switching points in light-driven reactions, but accurately predicting them usually requires computations. A researcher from Shibaura Institute of Technology has developed a new low-cost quantum chemistry method that can simultaneously describe ground and excited molecular states while efficiently locating these elusive structures. The approach reproduces benchmark geometries with strong accuracy and enables practical simulations of photochemical processes, making it promising for applications in photocatalysis, solar cells, and biological light-response studies.

KAISTannounced on the 1st of June that a research team led by Professor Seung Jun Hwang of the Department of Chemistry, through joint research with Professor Jaeyune Ryu’s team from the Department of Chemical and Biological Engineering at Seoul National University , has proposed a new catalyst design strategy that can improve the efficiency of key reactions that generate electricity inside batteries and fuel cells.

An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that is providing scientists with a natural laboratory to study extreme physics.

Plastics, medicines, cosmetics – there are very few everyday products that do not rely on using fossil resources. A European research team led by Charité – Universitätsmedizin Berlin is now aiming to revolutionize this cornerstone of the chemical industry: as part of the CarboNcare project, scientists are developing bacteria that can produce important chemical base materials from sustainable methanol – thereby replacing fossil resources. The project is funded by a €3.1 million Pathfinder Grant from the European Innovation Council (EIC), which specifically supports groundbreaking innovations with high market potential.

The energy-efficient desalination system produces fresh water without chemical additives and transforms leftover salts into useful materials. Big takeaways：

A new desalination method produces drinking water from seawater without chemical additives.

The solar-powered system uses specially engineered black metal to absorb sunlight.

Its self-cleaning surface separates and collects salts, instead of dumping them as harmful brine waste.

From the salts, the system can extract lithium, a key material for rechargeable batteries.

The approach could help address global water shortages and growing mineral demand.

A new nanocomposite coating developed by researchers at Sultan Qaboos University provides highly effective protection for stainless steel exposed to harsh acidic conditions. By combining titanium dioxide nanoparticles with graphitic carbon nitride, the researchers achieved corrosion inhibition efficiencies of up to 98.2% and long-term stability in acidic environments. The technology could support more durable metal components in industries where corrosion remains a major operational challenge.

To realize the vision of "invisible" wearable optoelectronics such as smart contact lenses and ultrathin AR glasses, traditional, bulky optical components must be reinvented at the atomic level. XPANCEO researchers, alongside collaborators from NUS and UCT Prague, have taken a major step toward this goal by uncovering the extraordinary properties of the layered crystal molybdenum oxychloride MoOCl₂. Published in Nano Letters, the study provides the first experimental map of the material that possesses the strongest light-bending effect ever recorded in a natural substance, offering a direct path to miniaturizing high-performance optical hardware. The research reveals that MoOCl₂ is a sort of "chameleon" in the world of physics. Due to its extreme optical anisotropy, this crystal’s function depends entirely on its orientation. Oriented one way, the crystal reflects light like a metal; turned by 90 degrees, it becomes transparent like glass. With an in-plane birefringence value of about 2.2, the crystal can split and bend light with unprecedented efficiency. For XPANCEO’s development, this means the complex light manipulation required for AR displays can now be achieved using materials thousands of times thinner than the diameter of a human hair. 

Researchers have developed a new way to generate realistic synthetic training data for agricultural robots by recreating tomato cultivation environments in a virtual world. The approach could help overcome one of the biggest barriers in agricultural robotics: the time and labor required to collect and manually label real-world data under challenging greenhouse conditions such as changing lighting, dense foliage, and fruit occlusion.
