Gwangju Institute of Science and Technology Researchers Design AI-based Model that Predicts Extreme Wildfire Danger Combining artificial intelligence and weather forecast models can boost extreme wildfire forecasts by up to 7 days, finds new study Accurate wildfire risk prediction is essential for an efficient allocation of resources for their mitigation…

They achieve this by removing residual organic metal-binding ligands from the transition metal oxide thin films, enhancing device stability and performance Organic photovoltaics with a transition metal oxide (TMOs) interface layer are emerging as a promising alternative to conventional silicon-based photovoltaics. However, their electrical properties are often affected by unwanted…

With this approach, the developed photocathodes exhibit a remarkable stability and demonstrate sunlight-driven clean hydrogen production by water splitting Organic semiconductors (OSs) used in organic solar cells show promise as a candidate for facilitating clean hydrogen production from sunlight. However, they suffer from slow charge transfer and chemical instability. Addressing…

The approach involves a post-correction network optimized by a self-supervised machine learning framework to improve the quality of unfamiliar images High-quality visual displays rendered using the “path tracing” algorithm are often noisy. Recent supervised learning-based denoising algorithms rely on external training dataset, take long to train, and do not work…

Using water for morphology control of active layer thin films, researchers develop large-area, high-performance organic solar cells Organic solar cells (OSCs) are attractive owing to their lightweight, flexibility, and high power conversion efficiency. However, a lack of morphology control of the active layer makes it challenging to develop OSCs with…

The novel approach will help create a better gaming experience for all types of players Appropriately balancing a videogame’s difficulty is essential to provide players with a pleasant experience. In a recent study, Korean scientists developed a novel approach for dynamic difficulty adjustment where the players’ emotions are estimated using…

The breakthrough is achieved by replacing the electrode material with a cheaper and non-fragile alternative that resulted in high conversion efficiencies Organic solar cells (OSCs) are considered the future of photovoltaics due to their beneficial features like light weight, flexibility, and high conversion efficiency. But, most OSC electrodes use indium…

Batteries modified using new method can store charge better and last longer, say scientists Charging and discharging a lithium-ion battery multiple times causes significant change to the volume of the anode, reducing the battery capacity and battery life. Now researchers from GIST in Korea have developed a method to strengthen…
