Sentences with phrase «copper oxide material»

An international team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University has detected new features in the electronic behavior of a copper oxide material that may...

In the experiments, researchers used a technique called angle - resolved photoemission spectroscopy, or ARPES, to knock electrons out of a copper oxide material, one of a handful of materials that superconduct at relatively high temperatures — although they still have to be chilled to at least minus 135 degrees Celsius.

«In solid - state materials like copper oxides, there are many different effects and impurities that make these materials difficult to study.

This was achieved by coupling it with a material called praseodymium cerium copper oxide (PCCO).

The team is now using this strategy, called a Metal - Embedded - in - Oxygen - Matrix (MEOM), to predict the best oxide material — either copper or something new — to place next to the neutral copper strips to achieve the fastest reaction.

In their native state, even at super chilly temperatures, the copper - oxide materials are actually strong insulators.

In the copper - oxide material, instead of raising the temperature, the scientists raise the level of doping to «melt» the density waves at a particular «critical point.»

The superconducting materials are ceramics composed of complex oxides of copper and other metals.

Until now they have been difficult to make, particularly in large quantities, because they require precise ratios of raw materials containing metals such as bismuth, strontium and copper oxides to be ground together, before being heated to high temperatures to produce batches of about 10 grams of superconductor.

«Instead of searching for new single - electron antiferromagnetic insulators like copper oxide to make high - temperature superconductors, maybe we should be searching for new highly magnetic, metallic materials that have properties like iron but in an orbitally selective arrangement,» Davis said.

The project was conceived by researchers from MIT's Plasma Science and Fusion Center (PSFC), and aims within three years to develop superconducting electromagnets from a newly available material - a steel tape coated with an yttrium - barium - copper oxide compound.

Employing a strategic combination of detailed electronic structure calculations, combinatorial materials synthesis, and both traditional and high - throughout photoelectrochemistry measurements, the JCAP team identified earth - abundant copper and manganese vanadate complex oxides that meet highly demanding requirements for photoanodes: low band gap energy, stability under highly oxidizing conditions, and valence band alignment with respect to OER.

For example, a particle with a shell of copper oxide its aluminium core reduces carbon dioxide to carbon monoxide faster and more efficiently than particles made of either material alone.
