System monitors radiation damage to materials in real-time

A new system allows detailed real-time observations of how materials are affected by a high-radiation environment. The system could accelerate the development of better materials for nuclear plants.

Correlation between the structure and magnetic properties of ceramics

A team of Immanuel Kant Baltic Federal University (BFU) together with an international scientific group has studied a correlation between the structure of ceramic materials based on bismuth ferrite (BiFeO3) and their magnetic properties. In their work, the scientists determined the factors that affect structural evolution of materials and changes in their magnetic behavior. The work will help create new ceramic materials with given properties. The article was published in the Journal of Physics and Chemistry of Solids.

Adventures in phase space: Unified map on plastic and elastic glasses

Glasses are an enigma among solid phases. Like crystalline solids they are hard, but unlike crystals they are amorphous on the molecular scale. Because of this structural disorder, each piece of glass is technically out of equilibrium, and unique. As a result, its properties depend not only on its chemical ingredients, but on how it was cooled.

Machine learning to predict and optimise the deformation of materials

Researchers at Tampere University of Technology and Aalto University taught machine learning algorithms to predict how materials stretch. This new application of machine learning opens new opportunities in physics and possible applications can be found in the design of new optimal materials. The study has been published in the prestigious journal Nature Communications.

Massive new dark matter detector gets its 'eyes'

The LUX-ZEPLIN (LZ) dark matter detector, which will soon start its search for the elusive particles thought to account for a majority of matter in the universe, had its first set of "eyes" delivered Thursday.

Gravity is mathematically relatable to dynamics of subatomic particles

Albert Einstein's desk can still be found on the second floor of Princeton's physics department. Positioned in front of a floor-to-ceiling blackboard covered with equations, the desk seems to embody the spirit of the frizzy-haired genius as he asks the department's current occupants, "So, have you solved it yet?"

System monitors radiation damage to materials in real-time

In order to evaluate a material's ability to withstand the high-radiation environment inside a nuclear reactor, researchers have traditionally used a method known as "cook and look," meaning the material is exposed to high radiation and then removed for a physical examination. But that process is so slow it inhibits the development of new materials for future reactors.

NASA Administrator Statement on Passing of Rona Ramon

The following is a statement from NASA Administrator Jim Bridenstine about the passing of Rona Ramon, widow of Ilan Ramon:

Bettina Inclán Named to Head NASA Office of Communications

Bettina Inclán has been named by Administrator Jim Bridenstine to be NASA’s Associate Administrator for Communications.

Scientists design new material to harness power of light

Scientists have long known that synthetic materials -- called metamaterials -- can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as super-high resolution imaging. Now, scientists are taking the technology of manipulating light in a new direction.
