Designer binders protect silicon battery electrodes

In your electric car's battery, swapping an electrode with one made of silicon could let the battery store 10 times more energy. Why isn't silicon used? It falls apart. Scientists designed binders, small molecules and polymers, ...

Low-cost battery from waste graphite

Lithium ion batteries are flammable and the price of the raw material is rising. Are there alternatives? Yes: Empa and ETH Zürich researchers have discovered promising approaches as to how we might produce batteries out ...

Ultra-fast and ultra-sensitive hydrogen sensor

A KAIST team made an ultra-fast hydrogen sensor that can detect hydrogen gas levels under 1% in less than seven seconds. The sensor also can detect hundreds of parts per million levels of hydrogen gas within 60 seconds at ...

Electrically heated textiles now possible

Commuters, skiers, crossing guards and others who endure frozen fingers in cold weather may look forward to future relief as manufacturers are poised to take advantage of a new technique for creating electrically heated cloth ...

3-D printing materials for wound care and decorative elements

Cellulose nanofibrils have properties that can improve the characteristics of bio-based 3-D-printing pastes. VTT Technical Research Centre of Finland is developing a 3-D wound care product for monitoring wound condition in ...
