A protein mines, sorts rare earths better than humans, paving way for green tech      (via sciencedaily.com)     Original source 

Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.

A nanocrystal shines on and off indefinitely      (via sciencedaily.com)     Original source 

Optical probes have led to numerous breakthroughs in applications like optical memory, nanopatterning, and bioimaging, but existing options have limited lifespans and will eventually 'photobleach.' New work demonstrates a promising, longer-lasting alternative: ultra-photostable avalanching nanoparticles that can turn on and off indefinitely in response to near-infrared light from simple lasers.

Hidden in plain sight: Windshield washer fluid is an unexpected emission source      (via sciencedaily.com)     Original source 

Exhaust fumes probably come to mind when considering vehicle emissions, but they aren't the only source of pollutants released by a daily commute. Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles.

Source-shifting metastructures composed of only one resin for location camouflaging      (via sciencedaily.com)     Original source 

Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.

Development of iron complex catalyst for selective and efficient conversion of methane to methanol      (via sciencedaily.com)     Original source 

A new iron complex has been developed as a catalyst for the oxidation of methane to selectively convert it to methanol. This complex can efficiently oxidize methane by internally trapping methane while preventing the overoxidation of the produced methanol. Using this complex, the direct and selective conversion of methane to methanol has been successfully achieved in an aqueous solution.

Twisting under the stroboscope -- Controlling crystal lattices of hybrid solar cell materials with terahertz light      (via sciencedaily.com)     Original source 

To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity. Some of the most promising candidates for high-efficiency low-cost solar cell applications are based on lead halide perovskite (LHP) semiconductors. Despite record-breaking solar cell prototypes, the microscopic origin of the surprisingly excellent optoelectronic performance of this material class is still not completely understood. Now, an international team of physicists and chemists has demonstrated laser-driven control of fundamental motions of the LHP atomic lattice.

Calcium rechargeable battery with long cycle life      (via sciencedaily.com)     Original source 

With the use of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater. Researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge -- the benchmark for practical use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte.

Physical chemists develop photochromic active colloids shedding light on the development of new smart active materials      (via sciencedaily.com)     Original source 

In nature, the skin of cephalopods (animals with tentacles attached to the head) exhibits unparalleled camouflage ability. Their skin contains pigment groups that can sense changes in environmental light conditions and adjust their appearance through the action of pigment cells. Although intricate in nature, this colour-changing ability is fundamentally based on a mechanical mechanism in which pigment particles are folded or unfolded under the control of radial muscles. Inspired by this natural process, a research team forms dynamic photochromic nanoclusters by mixing cyan, magenta and yellow microbeads, achieving photochromism on a macro scale.
