Crystallinity reduces resistance in all-solid-state batteries

Scientists examined the mechanisms behind the resistance at the electrode-electrolyte interface of all-solid-state batteries. Their findings will aid in the development of much better Li-ion batteries with very fast charge/discharge rates.

Draw-your-own electrodes set to speed up development of micro detection devices

Miniature devices for sensing biological molecules could be developed quicker thanks to a rapid prototyping method.

Living electrodes with bacteria and organic electronics

Researchers developed a method that increases the signal strength from microbial electrochemical cells by up to twenty times. The secret is a film with an embedded bacterium: Shewanella oneidensis.

A starch and graphene hydrogel geared towards electrodes for brain implants

Researchers have created hydrogels with electrical and antibacterial properties suitable for neural interfaces.

Faster-charging, safer batteries

Imagine a world where cell phones and laptops can be charged in a matter of minutes instead of hours, rolled up and stored in your pocket, or dropped without sustaining any damage.

Laser-driven electron accelerator fits on a microchip

Electrical engineers have developed a design for a laser-driven electron accelerator so small it could be produced on a silicon chip.

Thermoelectric cooling gets fit for microtechnology

Scientists have significantly improved the processing of thermoelectric devices so that they become quicker, more reliably and suitable for integration in microchips. This represents a decisive step towards the broad application of thermoelectric components in microtechnology.
