Compound could transform energy storage for large grids
In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn't shining and the wind doesn't blow.
Study boosts hope for cheaper fuel cells
Nitrogen-doped carbon nanotubes or modified graphene nanoribbons may be suitable replacements for platinum for fast oxygen reduction, the key reaction in fuel cells that transform chemical energy into electricity, according to Rice University researchers.
Polystyrene makes solar panels cheaper
Researchers are using polystyrene particles rather than expensive polymers to make the next generation of solar cells, which are used to make solar panels, more stable and even cheaper.
Molecular movie exposes perovskite solar cell's inner workings
A 'molecular movie' has revealed how perovskite solar cells respond to light. The work could help to explain why these structures are so adept at converting light into electricity.
Lab on a chip could monitor health, germs and pollutants
Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer.
Pac-Man meets biotechnology
Scientists increasingly use miniscule robots to solve a range of problems, from cancer treatment to water purification.
Environmental risks in 'green' material
Researchers have undertaken the first comparative life cycle analysis of piezoelectric materials as part of an EPSRC project.
Researchers invent novel materials for better batteries
Inventors are paving the way for the future with energy-efficient batteries for sensors, portable devices and electric cars.
A picture perfect power source
Using a standard inkjet printer and regular paper, scientists can now print power sources in any design imaginable.

Researchers have discovered significant new potentials for light harvesting through narrowing the bandgap of titania and graphene quantum dots.
Rechargeable first for promising battery tech
The first rechargeable sodium-carbon dioxide battery has been created with the help of a nanostructured cathode. The cheap and potentially powerful battery could fuel Mars vehicles as the red planet's atmosphere is 96% carbon dioxide or recycle carbon dioxide emissions on Earth.
Touch sensitive super stretchy skin shows promise for soft robots
A material that can emit different coloured light and sense touch - yet still stretch nearly five times its original length - has been invented by scientists in the US and Italy.
Dip coating to solve perovskite moisture sensitivity
Scientists from China and Australia have designed a water-resistant perovskite solar cell that can operate in a humid environment and maintain its efficiency over three weeks.

A new method for 3D printing ceramic microlattices has been developed by researchers in the US.
Doped electrodes cram charge into supercapacitors
A new supercapacitor electrode material has been created that can store much more energy than conventional supercapacitors.
Perovskite boosts silicon solar cell efficiency
A UK company claims it can boost the efficiency of a silicon solar cell by 20% by adding a layer of the light-sensitive crystal perovskite.
A step forward for graphene walkers
Scientists in China have developed a graphene-based paper which can fold itself into predesigned shapes when exposed to light or gentle heat. The material, which is created from graphene oxide, can also 'walk' across a table and turn a corner. Potential applications of the material include sensors, artificial muscles and robotics.
