Researchers have developed an artificial photosynthesis technology that could be a win/win...

Scientists at the Lawrence Berkeley National Laboratory and the University of California, Berkeley have created a hybrid system of bacteria and semiconducting nanowires that mimics photosynthesis. According to the researchers, their versatile, high-yield system can take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel.  Read More

Using layers of graphene, scientists claim to have created a photodetector that converts l...

Converting light to electricity is one of the pillars of modern electronics, with the process essential for the operation of everything from solar cells and TV remote control receivers through to laser communications and astronomical telescopes. These devices rely on the swift and effective operation of this technology, especially in scientific equipment, to ensure the most efficient conversion rates possible. In this vein, researchers from the Institute of Photonic Sciences (Institut de Ciències Fotòniques/ICFO) in Barcelona have demonstrated a graphene-based photodetector they claim converts light into electricity in less than 50 quadrillionths of a second.  Read More

Changing the color of the skin-like membrane is as simple as stretching it a tiny amount

A thin and flexible chameleon-like material developed by engineers at the University of California, Berkeley changes color when stretched or bent even tiny amounts. With potential applications in camouflage, structural fatigue sensors, display technologies, and more, the material's color changes reliably as it gets flexed thanks to rows of ridges that are precisely etched onto a silicon film one thousand times thinner than a human hair.  Read More

Researchers at the University of California, Riverside say they have found a way around th...

Researchers at the University of California, Riverside (UCR) have developed a silicon anode for lithium-ion batteries that outperforms current materials and gets around previous issues that would cause the battery to be inefficient and quickly degrade (or even fail catastrophically) with use. As the researchers focus on scaling up production, the advance could pave the way for higher-performance electric vehicles, electronics and all-around portable power.  Read More

Researchers at the University of California claim to have successfully created a roton str...

Helium-4 superfluid is a fascinating substance. With properties that seemingly defy normal physics, it leaks straight through glass, bubbles up out of containers, flows around objects and even climbs up walls. As if superfluid helium-4 was not strange enough, in 1941 it was also predicted that it should contain an exotic, particle-like excitation – a quasiparticle – called a roton. After many years of trying to verify this prediction, researchers at the University of California now claim to have successfully created a roton structure in an atomic superfluid of cesium-133.  Read More

Graphene is extremely strong for its weight, it's electrically and thermally conductive, and it's chemically stable ... but it isn't magnetic. Now, however, a team from the University of California, Riverside has succeeded in making it so. The resulting magnetized graphene could have a wide range of applications, including use in "spintronic" computer chips.  Read More

Research carried out at the University of California and the University of Barcelona has uncovered an enzyme inhibitor found to prevent and reverse the effects of diabetes in obese mice. In addition to discovering a potential form of treatment for the disease, scientists say the study has shone new light on healthy properties of fatty acids.  Read More

Chemists at the University of California, Riverside have created rewritable paper that can...

The paperless office – one of the promises of the new digital age – has not really eventuated. Instead, most organizations still print out large amounts of documents on paper that, according to the WWF, is being produced at around 400 million tons (362 million tonnes) a year and rising. So, wouldn’t it be great if we could just simply wipe off the print on paper and use it over and over again? Chemists at the University of California, Riverside (UCR) thought that this might be a good idea too, and have now created rewritable paper that can be printed on and erased more than 20 times before it needs to be discarded.  Read More

A new coating material developed by UCSD researchers could help make concentrated solar po...

The key factor when it comes to solar power plant efficiency – be they of the photovoltaic or concentrated solar power variety – is the amount of light that can be captured by the light-absorbing material and converted into electricity or heat. Researchers at the University of California, San Diego have developed a new nanoparticle-based material that promises to improve the efficiency of CSP plants with its ability to absorb and convert over 90 percent of the sunlight it captures into heat.  Read More

A team of researchers from Stanford University and the University of California, Berkeley, has created prototype radio-on-a-chip communications devices that are powered by ambient radio waves. Comprising receiving and transmitting antennas and a central processor, the completely self-contained ant-sized devices are very cheap to manufacture, don't require batteries to run and could give the "Internet of Things" (IoT) a serious kick start.  Read More
