Published Theoretical computations identify a solid-state hydrogen storage material's key bottleneck
(via sciencedaily.com) Magnesium hydride has long been touted for its potential to store large amounts of hydrogen, something essential if hydrogen is to play a role in powering a sustainable future. Yet, sluggish dehydrogenation kinetics and the high temperature required to decompose and produce hydrogen from the material have stymied its use. Now, researchers have identified why this is so, paving the way for future design guidelines and widespread commercial use.
Published Improving perovskite solar cell resistance to degradation
(via sciencedaily.com) Despite their huge potential, the way perovskite solar cells respond to external stimuli -- such as heat or moisture -- has a considerable impact on their stability. Researchers have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.
Published 'A perfect little system': Physicists isolate a pair of atoms to observe p-wave interaction strength for the first time
(via sciencedaily.com) Physicists have taken a first step in understanding quantum emergence -- the transition from 'one-to-many' particles -- by studying not one, not many, but two isolated, interacting particles. The result is a first, small step toward understanding natural quantum systems, and how they can lead to more powerful and effective quantum simulations. The team has measured the strength of a type of interaction -- known as 'p-wave interactions' -- between two potassium atoms. P-wave interactions are weak in naturally occurring systems, but researchers had long predicted that they have a much higher maximum theoretical limit. The team is the first to confirm that the p-wave force between particles reached this maximum.
Published A new tool helps map out where to develop clean energy infrastructure
(via sciencedaily.com) An update to the Energy Zones Mapping Tool, the Geospatial Energy Mapper is an online tool with an extensive catalog of mapping data for energy planning. It can help identify areas that are suitable for clean energy infrastructure projects.

Published New quantum computing architecture could be used to connect large-scale devices
(via sciencedaily.com) Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could be used to develop a large-scale network of quantum processors that could efficiently communicate with one another.
Published More links aren't necessarily better for hybrid nanomaterials
(via sciencedaily.com) Chemists have discovered more isn't always better when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals.
Published New type of entanglement lets scientists 'see' inside nuclei
(via sciencedaily.com) Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC) to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that's never been seen before.
Published High-performance visible-light lasers that fit on a fingertip
(via sciencedaily.com) Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to 267 petahertz per second, which is critical for applications such as quantum optics. The team is the first to demonstrate chip-scale narrow-linewidth and tunable lasers for colors of light below red -- green, cyan, blue, and violet.
