Researchers at Southern University of Science and Technology developed an adaptive beam shaping method for laser micro-grooving to shape tiny grooves with sub-micron accuracy—even in hard-to-machine materials like silicon carbide.

By combining smart simulations and real-time adjustments, their system “teaches” lasers to self-compensation deviation between experimental and target results caused by diffraction and polarization, achieving 5× higher precision than traditional patterned laser ablation methods.

“Here, you can think of the laser as a shaped knife, and you can achieve the desired groove shape with a single stroke”, says Prof. Shaolin Xu.

To realize a sustainable low-carbon society, it is essential to establish a catalytic process that converts various concentrations of CO₂ in combustion exhaust gases from thermal power plants and other sources into useful chemicals using renewable hydrogen. However, due to the high oxygen (O₂) content (about 10%) in such exhaust gases, conventional catalytic methods face a major challenge in that H₂ reacts preferentially with O₂, making efficient CO₂ conversion technically impossible. A research team led by Hokkaido University has developed a tandem system that continuously captures and converts CO₂ in a wide concentration range, from atmospheric levels to exhaust gases. Their work is published in the journal Industrial Chemistry & Materials on June 13, 2025.

A research team led by Dr. Kee Young Koo from the Hydrogen Research Department at the Korea Institute of Energy Research (President: Yi Chang-Keun, hereafter referred to as KIER) has developed a novel and more cost-effective method for synthesizing ammonia decomposition catalysts.

Researchers from Tel Aviv University and the Israel Institute for Biological Research in Ness Ziona have used the platform developed for COVID-19 vaccines to create the world’s first mRNA-based vaccine against a deadly, antibiotic-resistant bacterium. In this groundbreaking study, the researchers tested the vaccine’s resistance to the virulent pathogen that causes the disease and were able to demonstrate 100% protection against infection in animal models. The researchers now hope that this technology can be used to combat other lethal bacteria as well.
