Automation of Nuclear Chemistry Processes Leads to More Efficient Production of Astatine for Cancer Therapy

Department of Energy, Office of Science — Fri, 20 Dec 2024 14:45:26 EST

Astatine-211 (At-211) is a promising alpha emitting radioisotope for cancer therapy, but its short 7.2-hour half-life means that it must be handled quickly to minimize losses due to radioactive decay. In this research, scientists designed and tested an automated device for producing At-211 that improves production time and efficiency. The device also minimizes the dose of radioactivity to production staff and reduces the time needed to prepare samples for shipment.

This Prototype Sunscreen Protects Your Skin and Cools You Off, Too

American Chemical Society (ACS) — Thu, 19 Dec 2024 08:00:31 EST

A new sunscreen formula, described in ACS' Nano Letters, protects against both UV light and heat from the sun using radiative cooling. The prototype sunblock kept human skin up to 11 degrees Fahrenheit (6 degrees Celsius) cooler than bare skin, or around 6 F (3 C) cooler than existing sunscreens.

Springing Simulations Forward with Quantum Computing

Department of Energy, Office of Science — Wed, 18 Dec 2024 19:40:10 EST

Quantum computers have the potential to solve some problems much more efficiently than conventional computers. Researchers have now created a quantum computer algorithm for simulating coupled oscillators, systems of coupled masses and springs that are important for describing many real-world physical systems. The new algorithm results in exponentially faster simulation of coupled oscillators than ordinary algorithms.
