Thin film converts heat from electronics into energy

19-Apr-2018

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large industrial processes. Engineers at the University of California, Berkeley, have developed a ...

New technology could wean the battery world off cobalt

13-Apr-2018

Lithium-based batteries use more than 50 percent of all cobalt produced in the world. These batteries are in your cell phone, laptop and maybe even your car. About 50 percent of the world's cobalt comes from the Congo, where it's largely mined by hand, in some instances by children. But now, a ...

Hints from hemoglobin lead to better carbon monoxide storage

18-Sep-2017

Carbon monoxide is an insidious poison because it loves the iron in our blood; it pushes oxygen out of iron-based hemoglobin, leading to painful asphyxiation. This affinity for iron comes in handy in a newly created material that can absorb carbon monoxide far better than other materials, with ...

New form of matter unveiled: Time crystals

30-Jan-2017

To most people, crystals mean diamond bling, semiprecious gems or perhaps the jagged amethyst or quartz crystals beloved by collectors. To Norman Yao, these inert crystals are the tip of the iceberg. If crystals have an atomic structure that repeats in space, like the carbon lattice of a diamond, ...

Smallest. Transistor. Ever.

Research breaks major barrier in transistor size by creating gate only 1 nanometer long

11-Oct-2016

For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size ...

The cause of high Tc superconductivity at the interface between FeSe and SrTiO3

10-May-2016

Raising the superconducting transition temperature, the temperature above which a superconductor turns into a normal conductor, to a point where applications are practical is a dream in modern science and technology. In 1987 a superconductor with transition temperature above the boiling point of ...

Simplifying solar cells with a new mix of materials

29-Jan-2016

An international research team has simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. Arrays of solar cells are used in solar panels to convert sunlight to electricity. The special blend of materials--which could also prove ...

Diamonds may be the key to future NMR/MRI technologies

18-Dec-2015

Researchers with the Lawrence Berkeley National Laboratory and the University of California Berkeley have demonstrated that diamonds may hold the key to the future for nuclear magnetic resonance and magnetic resonance imaging technologies In a study led by Alexander Pines, a senior faculty ...

Coming to a monitor near you: A defect-free, molecule-thick film

01-Dec-2015

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale ...
