Hydride superionic conductor developed, implications for sustainable energy
An international research team developed a superionic conductor that negatively charged hydrogen, called hydride ions, diffuses fast. To better expedite hydrogen conductivity in the intermediate range, an international research team developed the first superionic conductor based on a negatively charged hydrogen atom, called a hydride ion. The team published their results, which produced superior conductivity…

Predicting solar cell performance from terahertz and microwave spectroscopy
Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of…

A ‘greener’ way to clean wastewater treatment filters
Membrane filters don’t require much energy to purify water, making them popular for wastewater treatment. To keep these materials in tip-top condition, they’re commonly cleaned with large amounts of strong chemicals, but some of these agents destroy the membranes in the process. Now, researchers have developed reusable nanoparticle catalysts that incorporate glucose to help efficiently…

New technology makes it possible to see clearly through murky water
Researchers overcome the limitations of traditional polarimetric underwater imaging by developing a new method that can automatically produce clear images through murky water. The new technology could be useful for searching for drowning victims, documenting submerged archaeological artifacts and monitoring underwater farms. Imaging clearly underwater is extremely challenging because the water and the particles in…

New technique will improve the construction of ice roads and bridges
A new study found that measuring the time it takes for a radar pulse to travel from a satellite to the sea surface and back again can reveal the thickness of river ice and dates when it is safe to travel on ice roads and bridges in Arctic regions. Many northern communities in Canada rely…

Computing carbon storage
Carbon capture and storage describes the process of injecting carbon dioxide from industrial sources into underground geological reservoirs, theoretically for thousands of years. Researchers used supercomputers to understand how carbon dioxide storage works at the level of micrometer-wide pores in rock. They found that two factors greatly impact the amount of carbon dioxide that can…

Using raw materials more sustainably
Insights into the oxidation of hydrocarbons at vanadium pentoxide pave the way for a new catalyst design. In the crystal structure of vanadium pentoxide, three different types of oxygen atoms are distinguished by how they link neighbouring vanadium atoms. The vibrational spectra of the oxide measured by Raman spectroscopy differ when the oxygen atoms with…

The case of the cloudy filters: Solving the mystery of the degrading sunlight detectors
Sun-facing satellites monitor the Sun’s ultraviolet (UV) light to give us advance warning of solar storms. But over the course of just a year or two, the metal filters in the detectors mysteriously lose their ability to transmit UV light. Now, scientists have found the first evidence indicating that carbonization is not the problem. Sun-facing…

New metric for designing safer streets
A new study shows how biometric data can be used to find potentially challenging and dangerous areas of urban infrastructure. By analyzing eye-tracking data from cyclists navigating Philadelphia’s streets, researchers found that these individual-based metrics can provide a more proactive approach for designing safer roadways for bicyclists and pedestrians. Current federal rules for installing safe…
