Scientists in Korea developed a photopatterning approach for emissive layer (EML) patterns using prepatterned photoresist based on a molecular crosslinking strategy. This approach enables ultra-high resolution up to 3000 ppi—fulfilling AR display requirements—without direct exposure of EML to etchants or UV irradiation, unlike conventional photolithography. The simple method offers a promising route for high-resolution OLEDs for VR/AR applications

Overcoming fundamental power limitations in single-frequency fiber lasers—long constrained by stimulated Brillouin scattering effect (SBS) and transverse mode instability effect (TMI)—Chinese researchers combined optic-acoustic-thermodynamic multi-physics comprehensive analysis and innovatively proposed the insight of using a regionally refractive index design to suppress SBS and TMI. Their ‘bat-type’ refractive-index fiber achieved the first kilowatt breakthrough in single-frequency fiber lasers internationally, which could provide a novel laser source for next-generation advanced detection and sensing systems.

Professor Tonggang Jiu's team at Shandong University achieved a significant improvement in the efficiency and stability of perovskite solar cells by regulating the NiO_x/perovskite interface chemistry by introducing a novel self-assembling molecule, (4-(2,7-dibromo-9,9-dimethylacridin-10(9H)-yl)butylphosphonic acid (2Br-4PADMAc), into the NiO_x/perovskite interface. This effectively suppressed Ni^>3+ generation and interfacial redox reactions, optimized energy level matching, and promoted high-quality film crystallization. Compared to the traditional molecule 2PACz, 2Br-4PADMAc exhibits stronger interfacial anchoring and a larger molecular dipole moment, which can improve hole transport efficiency and reduce PbI₂ accumulation. The inverse perovskite solar cell modified with this molecule achieved a photoelectric conversion efficiency of 25.28% and excellent stability. This research provides a new strategy for optimizing the efficiency and stability of NiO_x-based perovskite solar cells through interfacial molecule design. The article was published as an open access research article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

In a groundbreaking exploration of the environmental impacts of fires, researchers are shedding light on how gaseous smoke pollutants affect both air and soil quality. This critical study, titled "Impact of Gaseous Smoke Pollutants from Modelled Fires on Air and Soil Quality," is spearheaded by Mikhail Nizhelskiy from the Academy of Biology and Biotechnology Named After D.I. Ivanovskiy at Southern Federal University in Rostov-on-Don, Russian Federation. His work offers a deeper understanding of the often-overlooked consequences of fires on our environment.

Paper packaging is a sustainable alternative to plastic. However, as it is permeable to air, food packaged in paper loses its flavour over time, and undesirable substances such as solvents can penetrate the packaging. Up to now, extensive tests were necessary for each type of paper to determine to what extent and how quickly this happens. A research team led by Karin Zojer from the Institute of Solid State Physics at Graz University of Technology (TU Graz) has now developed an AI-based prediction system that calculates how permeable different types of paper are to volatile organic substances. This significantly speeds up the development of new packaging materials. The prediction tool, which was developed as part of the CD Laboratory for Mass Transport through Paper, is already being used by a paper manufacturer.

Researchers from Zhengzhou University have released the most comprehensive review to date on the rapidly expanding field of element doped biochar. The study explains how simple biowaste can be transformed into powerful engineered materials with exceptional performance in pollution control, energy storage, soil improvement and industrial catalysis. The findings highlight the growing importance of advanced carbon materials in global efforts to address environmental and energy related challenges.

Silicon, aluminium and lithium are the most critical raw materials on the planet. Their scarcity and the complexity of extracting them could hinder the development of technologies that are key to the green transition. This is one of the main conclusions of a study by the INGENIO Institute, a joint centre of the Spanish National Research Council (CSIC) and the Universitat Politècnica de València (UPV), in collaboration with the University of Rome, the Universitat de València and the University of London.
