A highly efficient, wearable self-charging power system is reported, which consists of a triboelectric nanogenerator (TENG) with fabric coated by MXene paste as conductive layer and micro-supercapacitors (MSCs) with graphene films as electrode.

Super-resolution imaging is essential for visualizing fine biological structures beyond the diffraction limit. To advance this field, Scientists in Korea developed a super-resolution imaging system based on a novel multifocal metalens. This ultrathin metalens generates dense, uniform focal arrays optimized for image scanning microscopy (ISM), achieving twice the resolution of conventional wide-field (WF) imaging. The technique successfully revealed fine neuronal structures in brain organoids and is expected to open new avenues for advanced optical microscopy systems.

Persistent organic pollutants such as DDT and lindane still pollute the environment and affect humans decades after their use. ETH researchers have developed a new electrochemical process that completely dehalogenates these long-lived toxins and converts them into valuable industrial chemicals. 

The method uses cheap equipment, prevents side reactions and could be used on contaminated landfills, soils or sludge. Mobile systems could be used on site in the future – an important step towards the remediation of contaminated sites and the creation of a sustainable circular economy. 

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) and Prof. Ka-Hyun Kim of the Department of Physics at Chungbuk National University (President Koh Chang-Seup, hereafter “CBNU”) has successfully identified, for the first time, the specific types of defects responsible for efficiency loss in silicon heterojunction (SHJ) solar cells. The findings are expected to significantly contribute to improving solar cell efficiency when combined with defect-suppression (passivation) techniques.

An international research team from the Songshan Lake Materials Laboratory (SLAB), the Institute of Physics at the Chinese Academy of Sciences, and the International Iberian Nanotechnology Laboratory have developed a novel lead-doped ruthenium-iridium oxide (RuIrPbOₓ) catalyst that exhibits outstanding stability and efficiency for oxygen evolution reactions (OER) in proton exchange membrane water electrolyzers (PEMWEs) operating at high current densities of 3 A/cm². This work addresses longstanding challenges in catalyst durability and performance under acidic, harsh conditions, paving the way for more reliable and cost-effective hydrogen production technologies.
