Physicists develop method to detect single-atom defects in semiconductors

Posted by in categories: materials, particle physics

One of the challenges of cramming smarter and more powerful electronics into ever-shrinking devices is developing the tools and techniques to analyze the materials that make them up with increasingly intimate precision.

Physicists at Michigan State University have taken a long-awaited step on that front with an approach that combines high-resolution microscopy with ultrafast lasers.

The technique, described in the journal Nature Photonics, enables researchers to spot misfit atoms in semiconductors with unparalleled precision. Semiconductor physics labels these atoms as “defects,” which sounds negative, but they’re usually added to materials on purpose and are critically important to the performance of semiconductors in today’s—and tomorrow’s—devices.

Planetary Boundary Layer Revealed: Satellites Illuminate Atmospheric Mysteries

Posted by in categories: climatology, satellites, sustainability

New research has unraveled the complex dynamics of the planetary boundary layer, enhancing satellite detection of atmospheric pollutants and aiding environmental management and climate modeling efforts.

A new study has provided groundbreaking insights into Earth’s planetary boundary layer (PBL), a crucial area that affects air quality and climate. By analyzing satellite data, researchers have explored how the temperature gradient from the surface to the atmosphere impacts the identification of atmospheric pollutants, offering a deeper understanding of atmospheric thermal contrasts (TC).

The endeavor to keep tabs on and curb air pollution has been stymied by the enigmatic nature of the planetary boundary layer (PBL). This atmospheric strip, in constant caresses with the Earth’s surface, is a hotbed for pollutants. Yet, its mercurial dance through time and across geographies presents a formidable scientific puzzle. Given these hurdles, an in-depth dissection of the thermal contrast (TC) that delineates this layer is imperative.

Surprising Vortex Uncovered — Supercomputers Reveal Hidden Secrets of Solar Technology

Posted by in categories: particle physics, solar power, supercomputing, sustainability

In the past decade, metal-halide perovskites have rapidly progressed as a semiconductor, surpassing silicon in their ability to convert light into electric current since their initial discovery.

Simulations on TACC’s Frontera and Lonestar6 supercomputers have revealed surprising vortex structures in quasiparticles of electrons and atoms, called polarons, which contribute to generating electricity from sunlight.

This new discovery can help scientists develop new solar cells and LED lighting. This type of lighting is hailed as an eco-friendly, sustainable technology that can reshape the future of illumination.

Quick-Cooling Oddballs Rewrite Neutron Star Physics

Posted by in categories: quantum physics, space

Recent observations by ESA’s XMM-Newton and NASA ’s Chandra have revealed three unusually cold, young neutron stars, challenging current models by showing they cool much faster than expected.

This finding has significant implications, suggesting that only a few of the many proposed neutron star models are viable, and pointing to a potential breakthrough in linking the theories of general relativity and quantum mechanics through astrophysical observations.

A “Word Processor” for Genes — Scientists Unveil Fundamentally New Mechanism for Biological Programming

Posted by in category: biotech/medical

Arc Institute scientists have discovered the bridge recombinase mechanism, a revolutionary tool that enables fully programmable DNA rearrangements.

Their finding, detailed in a recent Nature publication, is the first DNA recombinase that uses a non-coding RNA for sequence-specific selection of target and donor DNA molecules. This bridge RNA is programmable, allowing the user to specify any desired genomic target sequence and any donor DNA molecule to be inserted.
