New Materials to Improve Solar Cell Efficiency

October 12, 2021

New research based on calculations run on NERSC’s Cori supercomputer has shown that, counter to common beliefs, all-inorganic materials known as perovskites have the potential for greater energy generation efficiencies in solar cells compared to materials currently being used. The University of California at Santa Barbara research team’s results were featured on the cover of the October 20, 2021 journal Cell Reports Physical Science. Read More »

Matter & Antimatter Creation from Real Photon Interactions

July 27, 2021

Scientists have produced definitive evidence for a phenomenon predicted more than 80 years ago: the creation of electron/positron pairs from the interaction of two real photons of light The results are based on a detailed analysis of data from the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory.

Projected Land Ice Contributions to Sea Level Rise

May 5, 2021

Holding global temperature rise to no more than 1.5 degrees C – rather than following current emissions pledges – could halve the sea level rise from melting land ice by the year 2100, according to research published by an international team of scientists in the journal Nature. The study updates previous ones using the latest socio-economic scenarios and a coordinated exploration of uncertainties in the models. Read More »
