Sound waves create mist that can act like 'plant sunscreen'

RMIT University researchers have developed a new way to coat fragile surfaces, including living plant leaves, using high‑frequency sound waves to create a fine mist that can act like a plant sunscreen. The approach tackles a long‑standing challenge in materials science: many promising coatings require high temperatures or harsh processing, making them unsuitable for delicate surfaces such as living tissue, soft plastics or emerging electronic materials. The research paper, "Ambient one‑step synthesis and direct coating of highly crystalline covalent organic frameworks on arbitrary surfaces," is published in Science Advances.

The party for the DnD game I'm currently running- They still don't have a party name because they still aren't sure they like each other ✨

Three of the Ladies Von Zarovich from the (very modified) Curse of Strahd game I'm running! These three are currently doing a lot of bullying my players and I love them.

New calcium-ion battery design delivers high performance without lithium

A bold new calcium battery design could challenge lithium and energize the future of clean power.

Scientists at The Hong Kong University of Science and Technology (HKUST) have reported a major advance in calcium-ion battery (CIB) research that could reshape how energy is stored and used in daily life. By incorporating quasi-solid-state electrolytes (QSSEs), the team developed a new type of CIB designed to improve both performance and sustainability. The technology could support applications ranging from renewable energy storage systems to electric vehicles. The work appears in Advanced Science under the title "High-Performance Quasi-Solid-State Calcium-Ion Batteries from Redox-Active Covalent Organic Framework Electrolytes." As countries expand renewable energy production, the need for dependable and efficient battery storage continues to grow. Lithium-ion batteries (LIBs) currently dominate the market, but concerns remain about limited lithium resources and the practical limits of their energy density. These constraints have intensified the search for alternative battery chemistries that can meet long-term global energy demands.
