The precious metals, such as platinum, palladium and rhodium, in catalytic converters make the vehicle devices attractive to thieves, but University of Central Florida researchers are working to reduce the amount of precious metals needed in them—down to single atoms—while still maximizing their effectiveness.

A gun control law signed by Gov. J.B. Pritzker of Illinois in January 2023 immediately faced opposition from a group key to the law’s enforcement: sheriffs. They are county-level, locally elected public officials who run jails, provide courthouse security, and, in many counties, are the primary providers of law enforcement services.

The importance of solar power as a renewable energy resource is increasing. Sunlight contains high-energy UV light with a wavelength shorter than 400 nm, which can be broadly used, for example, for photopolymerization to form a resin and activation of photocatalysts to drive reactions that generate green hydrogen or useful hydrocarbons (fuels, sugars, olefins, etc.). The latter of these is often called “artificial photosynthesis.” Photocatalytic reaction by UV light to efficiently kill viruses and bacteria is another important application.

Understanding the elastic properties of solid-state ionic conductors, also known as superionic materials, is a crucial challenge in developing the solid-state electrolytes (SSEs) that could replace the liquid organic electrolytes used today, thereby improving safety in commercial Li-ion batteries.

A 2022 survey by the Australian Institute of Criminology found three in four app users surveyed had experienced online abuse or harassment when using dating apps. This included image-based abuse and abusive and threatening messages. A further third experienced in-person or off-app abuse from people they met on apps. Read Full Article Here source: Phys.org

Caddisflies are an order of aquatic insects with high diversity. In Thailand, more than 1,000 caddisfly species are known to occur, and a recent study in the journal Check List shows that their diversity in the country is even greater than previously suggested.

Astronomers have captured a spectacular, ongoing collision between at least three galaxy clusters. Data from NASA’s Chandra X-ray Observatory, ESA’s (European Space Agency’s) XMM-Newton, and a trio of radio telescopes is helping astronomers sort out what is happening in this jumbled scene. Collisions and mergers like this are the main way that galaxy clusters can grow into the gigantic cosmic edifices seen today. These also act as the largest particle accelerators in the universe.
