Solar cells as light as a soap bubble

Imagine solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon.

Engineers use rust to build a solar-powered battery

Ordinary metal oxides, such as rust, can be fashioned into solar cells capable of splitting water into hydrogen and oxygen.

Lumiode, Inc.

Lumiode is a spin out from Columbia University focused on commercializing micro-LED displays. Dr Vincent Lee, the company's CEO spoke to IDTechEx Principal Analyst Dr Harry Zervos about Lumiode's technology, roadmaps and addressable markets.

Lithium battery component found to harm key soil microorganism

The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium, according to research.

Wearable robot transforms musicians into three-armed drummers

Researchers have built a wearable robotic limb that allows drummers to play with three arms. The two-foot long "smart arm" can be attached to a musician's shoulder. It responds to human gestures and the music it hears.

New kind of polymer could lead to artificial muscles

A completely new hybrid polymer has been developed by researchers that might one day be used in artificial muscles or other life-like materials; for delivery of drugs, biomolecules or other chemicals; in materials with self-repair capability; and for replaceable energy sources.

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science.

New 3-D printing method creates complex micro objects

The technique, using patterned ultraviolet light and a custom-shaped flow of polymer material, creates 3-D objects that can be first designed with software and could be used in a variety of biomedical and industrial applications.

Water-in-salt aqueous lithium ion battery technology

A team of researchers have devised a groundbreaking "Water-in-Salt" aqueous Lithium ion battery technology that could provide power, efficiency and longevity comparable to today's Lithium-ion batteries, but without the fire risk, poisonous chemicals and environmental hazards of current Lithium batteries.

Self-healing gel makes electronics more flexible, advances batteries

Researchers have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.

Chemist aims to put his nanohoops into future devices

Nanohoops, can be made using both carbon and other atoms. Because they efficiently absorb and distribute energy, they may be useful in solar cells, organic light-emitting diodes or as new sensors or probes for medicine.
