Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations      (via sciencedaily.com)     Original source 

Mechanically responsive molecular crystals are extremely useful in soft robotics, which requires a versatile actuation technology. Crystals driven by the photothermal effect are particularly promising for achieving high-speed actuation. However, the response (bending) observed in these crystals is usually small. Now, scientists address this issue by inducing large resonated natural vibrations in anisole crystals with UV light illumination at the natural vibration frequency of the crystal.

New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation      (via sciencedaily.com)     Original source 

Organic solar cells show great promise for clean energy applications. However, photovoltaic modules made from organic semiconductors do not maintain their efficiency for long enough under sunlight for real world applications. Scientists have now revealed an important reason why organic solar cells rapidly degrade under operation. This new insight will drive the design of more stale materials for organic semiconductor-based photovoltaics, thus enabling cheap and renewable electricity generation.

Chemists propose ultrathin material for doubling solar cell efficiency      (via sciencedaily.com)     Original source 

Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.

Laser light hybrids control giant currents at ultrafast times      (via sciencedaily.com)     Original source 

The flow of matter, from macroscopic water currents to the microscopic flow of electric charge, underpins much of the infrastructure of modern times. In the search for breakthroughs in energy efficiency, data storage capacity, and processing speed, scientists search for ways in which to control the flow of quantum aspects of matter such as the 'spin' of an electron -- its magnetic moment -- or its 'valley state', a novel quantum aspect of matter found in many two dimensional materials. A team of researchers has recently discovered a route to induce and control the flow of spin and valley currents at ultrafast times with specially designed laser pulses, offering a new perspective on the ongoing search for the next generation of information technologies.

Pollution monitoring through precise detection of gold nanoparticles in woodlice      (via sciencedaily.com)     Original source 

Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.
