Turn off porch light to aid caterpillars -- and safeguard backyard ecosystems      (via sciencedaily.com) 

Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.

Researchers get to the 'bottom' of how beetles use their butts to stay hydrated      (via sciencedaily.com) 

Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.

How the 'marsupial sabertooth' thylacosmilus saw its world      (via sciencedaily.com) 

A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.

'Green' hydrogen: How photoelectrochemical water splitting may become competitive      (via sciencedaily.com) 

Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical 'green' hydrogen production can be reduced dramatically, the study shows.

Perovskite solar cells from the slot die coater -- a step towards industrial production      (via sciencedaily.com) 

Solar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. Scientists are investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.

Minimizing electric vehicles' impact on the grid      (via sciencedaily.com) 

Some projections show that widespread adoption of electric vehicles might require costly new power plants to meet peak loads in the evening. A new study shows that placing EV charging stations strategic ways and setting up systems to initiate charging at delayed times could lessen or eliminate the need for new power plants.

A safe synthesis of hydrogen peroxide inspired by nature      (via sciencedaily.com) 

Scientists report the safe synthesis of hydrogen peroxide (H2O2), an oxidizing agent used in multiple industries including semiconductors, using a new rhodium-based catalyst. The catalyst is based on natural enzymes found in extremophile microorganisms, and the reaction meets three chemical ideals for H2O2 production: safe, use of a single vessel, and direct synthesis.

Salt could play key role in energy transition      (via sciencedaily.com) 

A common ingredient -- salt -- could have a big role to play in the energy transition to lower carbon energy sources. A study describes how large underground salt deposits could serve as hydrogen holding tanks, conduct heat to geothermal plants, and influence CO2 storage. It also highlights how industries with existing salt expertise, such as solution mining, salt mining, and oil and gas exploration, could help.

Nanoparticles self-assemble to harvest solar energy      (via sciencedaily.com) 

Researchers design a solar harvester with enhanced energy conversion capabilities. The device employs a quasiperiodic nanoscale pattern, meaning most of it is an alternating and consistent pattern, while the remaining portion contains random defects that do not affect its performance. The fabrication process makes use of self-assembling nanoparticles, which form an organized material structure based on their interactions with nearby particles without any external instructions. Thermal energy harvested by the device can be transformed to electricity using thermoelectric materials.

Perovskites, a 'dirt cheap' alternative to silicon, just got a lot more efficient      (via sciencedaily.com) 

Researchers typically synthesize perovskites in a wet lab, and then apply the material as a film on a glass substrate and explore various applications. A team has instead proposes a novel, physics-based approach, using a substrate of either a layer of metal or alternating layers of metal and dielectric material -- rather than glass.
