Seeing the Color of Entangled Photons in Molecular Systems

Spectroscopy allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. This research examines the potential of spectroscopy techniques that rely on quantum entanglement of these photons. These methods can reveal information about molecules not possible with traditional spectroscopy. They also reduce the damage spectroscopy causes to samples.

UC Irvine-led research team discovers new property of light

Irvine, Calif., May 6, 2024 – A research team headed by chemists at the University of California, Irvine has discovered a previously unknown way in which light interacts with matter, a finding that could lead to improved solar power systems, light-emitting diodes, semiconductor lasers and other technological advancements.

UC Irvine scientists create new chemical imaging method

Irvine, Calif., Jan. 4, 2023 – A new visualization technology that captures spectral images of materials in the mid-infrared part of the electromagnetic spectrum has been developed by scientists at the University of California, Irvine. The discovery, which was recently featured on the cover of the journal Science Advances, promises to help researchers and industries across many fields, including medical and tech, quickly visualize the chemical composition of various materials or tissues.

International team visualizes properties of plant cell walls at nanoscale

To optimize biomaterials for reliable, cost-effective paper production, building construction, and biofuel development, researchers often study the structure of plant cells using techniques such as freezing plant samples or placing them in a vacuum. These methods provide valuable data but often cause permanent damage to the samples.

One-dimensional red phosphorous glows in unexpected ways

In a study published in Nature Communications, an international team led by Aalto University researchers has found that fibrous red phosphorous, when electrons are confined in its one-dimensional sub-units, can show large optical responses – that is, the material shows strong photoluminescence under light irradiation. Red phosphorous, like graphene, belongs to a unique group of materials discovered in 2017 called one-dimensional van der Waals (1D vdW) materials.

A COSMIC Approach to Nanoscale Science

COSMIC, a multipurpose X-ray instrument at Berkeley Lab’s Advanced Light Source, has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.

Building a Giant 2D Map of the Universe to Prepare for the Largest 3D Map

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.

Scientists publish largest 3D map of the universe ever created

A new three-dimensional map, built after decades of collecting and analyzing data from the skies, shows how the universe has changed and expanded over an 11-billion-year period. The map, published online late Sunday, is the largest 3D map of the universe ever created, and shows that about 6 billion years ago, the universe began accelerating more rapidly than it had in the 8 billion years that came before.

At the Interface of Organic Chemistry and Nanotechnology with Adam Braunschweig

Adam Braunschweig—a CUNY ASRC associate professor—is a user at Brookhaven Lab’s Center for Functional Nanomaterials (CFN) studying how molecules in organic semiconductor thin films pack together.

Now Complete, Telescope Instrument is Poised to Begin Its Search for Answers About Dark Energy

Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal approval milestone prior to startup.

Register to Join a Special April 16 Media Tour of a Telescope Instrument that Will Create a 3D Map of Millions of Galaxies

Members of the media are invited to attend a mid-April dedication of the Dark Energy Spectroscopic Instrument (DESI), which is scheduled to begin its five-year mission to construct a 3D map of the universe in the coming months.
