Battery-in-screen paves way to ultra-thin smartphones

Scientists in Hong Kong and China have combined a semi-transparent arrangement of anodes and cathodes with a transparent electrolyte to make the first ever photoluminescent microbattery that can simultaneously act as a power supply and a full-colour display.

Jelly implant keeps an eye on body oxygen levels

Although smaller than a grain of rice, a phosphorescent hydrogel implant that monitors tissue oxygen could end amputations in people with blocked blood vessels or help athletes design better training programmes. The first of these tiny but durable devices has survived more than four years - implanted in the foot of the researchers who created it.

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.

New light harvesting potentials

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.

Ceramics made stronger with 3D printing

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.
