Research Team Unlocks Secret Path to a Quantum Future

October 12, 2021

In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins of two nuclei in a molecule, with each spin’s “up” or “down” orientation storing information in the way that a “0” or “1” state stores information in a classical data bit. In those early days of quantum computers, the combined orientation of the two nuclei – that is, the molecule’s quantum state – could only be preserved for brief periods in specially tuned environments. In...

This is What a Solid Made of Electrons Looks Like

September 29, 2021

If the conditions are just right, some of the electrons inside a material will arrange themselves into a tidy honeycomb pattern — like a solid within a solid. Physicists have now directly imaged these ‘Wigner crystals’, named after the Hungarian-born theorist Eugene Wigner, who first imagined them almost 90 years ago.

Researchers had convincingly created Wigner crystals and measured their properties before, but this is the first time that anyone has actually taken a snapshot of the patterns, says study co-author Feng Wang, a physicist at the University of California, Berkeley. “If...

LED Material Shines Under Strain

August 26, 2021

Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more energy as heat instead of light.

Now, as reported in the journal Science, a team led by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has demonstrated an approach for achieving near 100% light-emission efficiency at all brightness...

NASA Sweetens the Pot: Team Wins Competition to Make Space Sugar

August 24, 2021

When Stefano Cestellos-Blanco entered graduate school at the University of California, Berkeley, in 2016, he never dreamed he’d be trying to manufacture sugar in space.

But what turned out to be an after-hours research project, stimulated by a NASA competition to spin sugar directly from carbon dioxide, is now a winner.

The sugar-making process developed by Cestellos-Blanco and his UC Berkeley team, led by chemist and professor Peidong Yang, shared the top prize — $650,000 — with two other teams competing in the...

Enel Foundation Forms Tech Innovation Hub with California University

August 13, 2021

A new scientific and technological innovation hub has been established at the University of California, Berkeley, by the Enel Foundation and the Center for Sustainable Materials and Innovation (CSMI).

Alessandra Lanzara, head of CSMI, Professor of Physics at UC Berkeley, said the hub will “solve some of the most pressing sustainable development goals around materials design and the circular economy”.

Researchers from Enel and from both Italian and US universities will collaborate on the research and development of solutions that have the potential to...

Graphene ‘Camera’ Captures Real-Time Electrical Activity of Beating Heart

June 16, 2021

Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image — almost like a video camera — of the faint electric fields generated by the rhythmic firing of the heart’s muscle cells.

The graphene camera represents a new type of sensor useful for studying cells and tissues that generate electrical voltages, including groups of neurons or cardiac muscle cells. To date, electrodes or chemical dyes have been used to measure electrical firing in these cells. But electrodes and dyes measure the voltage at one...

New Process Makes ‘Biodegradable’ Plastics Truly Compostable

April 21, 2021

Biodegradable plastics have been advertised as one solution to the plastic pollution problem bedeviling the world, but today’s “compostable” plastic bags, utensils and cup lids don’t break down during typical composting and contaminate other recyclable plastics, creating headaches for recyclers. Most compostable plastics, made primarily of the polyester known as polylactic acid, or PLA, end up in landfills and last as long as forever plastics.

University of California, Berkeley, scientists have now invented a way to make these compostable plastics break down more easily, with just...

Scientists Uncover a Process that Stands in the Way of Making Quantum Dots Brighter

March 26, 2021

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency.

A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example.

In a QLED TV screen, dots absorb blue light and turn it into green or red. At the low energies where TV screens operate, this conversion of light from...
