5+ hour, 28+ min ago  (741+ words) Researchers boosted graphene OLED efficiency to record levels by adding titanium dioxide and low-index layers around the electrode. This "sandwich" design improves light output while reducing losses, making flexible, bendable displays far more practical. The result: brighter screens, better battery…...

5+ hour, 29+ min ago  (801+ words) Researchers created a 3D "graphene ball" that improves lithium-ion batteries by enhancing conductivity and stability. It enables faster charging, longer lifespan, and ~27% higher energy density. The material also works as a high-capacity anode, helping batteries approach 800 Wh/L'making it a promising…...
