Artificial photosynthesis transforms carbon dioxide into liquefiable fuels (23/05/2019)

Chemists have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess carbon dioxide to store solar energy -- in the form of chemical bonds -- for use when the sun is not shining and in times of peak demand.

Big energy savings for tiny machines (23/05/2019)

Physicists demonstrate for the first time a strategy for manipulating the trillions of tiny molecular nanomachines inside us that work to keep us alive, to maximize efficiency and conserve energy. The breakthrough could impact numerous fields, including creating more efficient computer chips and solar cells for energy generation.

Virutally energy-free superfast computing invented by scientists using light pulses (23/05/2019)

A new invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without high energy costs.

Quantum cloud computing with self-check (23/05/2019)

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Breakthrough in new material to harness solar power (23/05/2019)

Physicists are pushing the performance of solar cells to levels never before reached. They have made a significant breakthrough in the chemical formula and process to make a new material. The ultra-high efficiency material called a tandem perovskite solar cell is being developed to help solve the world energy crisis.

Ultra-thin superlattices from gold nanoparticles for nanophotonics (23/05/2019)

Researchers led by Prof. Dr. Matthias Karg at the Institute of Physical Chemistry report a simple technique for developing highly ordered particle layers. The group worked with tiny, deformable spherical polymer beads with a hydrogel-like structure. Hydrogels are water-swollen, three-dimensional networks. Such structures are used as super-absorbers in such products as babies' nappies due to their ability to soak up large quantities of liquids.

Strain enables new applications of 2-D materials (23/05/2019)

Superconductors' never-ending flow of electrical current could provide new options for energy storage and superefficient electrical transmission and generation, to name just a few benefits. But the signature zero electrical resistance of superconductors is reached only below a certain critical temperature, hundreds of degrees Celsius below freezing, and is very expensive to achieve.

Octopus-inspired wearable sensor (22/05/2019)

Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge. Now, a team of researchers reports the development of a graphene-based adhesive biosensor inspired by octopus "suckers." They report their findings in ACS Applied Materials & Interfaces.

Methane-consuming bacteria could be the future of fuel (14/05/2019)

Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic bacteria have long fascinated researchers. But how, exactly, these bacteria naturally perform such a complex reaction has been a mystery.

Researchers find way to build potassium-oxygen batteries that last longer (14/05/2019)

Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation's power grid and longer-lasting batteries in cell phones and laptops.
