Ethylene oxide is a “platform chemical” with a $40 billion annual worldwide market used in the production of plastics, textiles and many other common products. Tufts University chemists discovered an inexpensive way to reduce CO₂ emissions and decrease the need for chlorine to produce the chemical. 

Newly published research from the University of Oklahoma proves that adding a covering to colloidal quantum dots made of perovskite neutralizes surface defects and stabilizes the surface lattices. Doing so prevents them from darkening or blinking.

An early-career physicist mathematically connects timelike and spacelike form factors, opening the door to further insights into the inner workings of the strong force. A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. One reaction is known as the spacelike process, where an electron is bounced off a pion. The second reaction, known as the timelike process, is when an electron and antielectron collide, annihilate each other, and produce two pions. The lattice QCD numerical calculation is simultaneously able to describe the spacelike and timelike processes, demonstrating the interconnectedness of different reactions described by QCD. While this connection had been observed experimentally, now physicists have the math to corroborate it.

Jefferson Lab’s heating, ventilation and air conditioning professionals ensure optimal operation of operational and scientific facilities through their technical expertise.

Quantum information scientists at the Department of Energy’s Oak Ridge National Laboratory successfully demonstrated a device that combines key quantum photonic capabilities on a single chip for the first time.

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory will contribute to the DOE’s newly established Fusion Innovative Research Engine (FIRE) Collaboratives. These collaborative teams were created to bridge basic science research programs with the needs of the growing fusion industry. In total, the DOE announced $107 million in funding for six projects under this initiative.

It may be the smallest, shortest chorus dance ever recorded. 

As reported in Science Advances, an international team of researchers observed how electrons, excited by ultrafast light pulses, danced in unison around a particle less than a nanometer in diameter. Researchers measured this dance with unprecedented precision, achieving the first measurement of its kind at the sub-nanometer scale. 

The synchronized dance of electrons, known as plasmonic resonance, can confine light for brief periods of time. That light-trapping ability has been applied in a wide range of areas, from turning light into chemical energy to improving light-sensitive gadgets and even converting sunlight into electricity. While they’ve been studied extensively in systems from several centimeters across to those just 10 nanometers wide, this is the first time researchers were able to break the field’s “nanometer barrier.”

Rice researchers found that a carbon material known as monolayer amorphous carbon is eight times tougher than graphene.
