Headline: Seeing clearly into a new realm -- researchers prototype a new generation of quantum microscopy

■ Release Date: 2022.11.7

■ Published by: University of Technology Sydney

■ Keywords: ferromagnet, boron nitride, quantum microscopy

■ Abstract:

With the advance of quantum technologies, new microscopy modalities are becoming possible -- ones that can see electric currents, detect fluctuating magnetic fields, and even see single molecules on a surface. A prototype of such a microscope, demonstrating high resolution sensitivity, has been developed by an Australian research team.

Headline: Ceramics that breathe oxygen at lower temperatures help us breathe cleaner air

■ Release Date: 2022.11.8

■ Published by: Tohoku University

■ Keywords: cerium, zirconium, ceramics

■ Abstract:

With the shift to electric cars a cumbersome process, improvements to exhaust gas purification in petrol or diesel cars are crucial in the fight to reduce emissions. A research group has developed a Cerium-Zirconium-based oxide that boosts the purifying qualities of ceramics inside catalytic converters -- a device attached to conventional cars that converts harmful gases to less-toxic pollutants.

Headline: New quantum phase discovered for developing hybrid materials

■ Release Date: 2022.11.8

■ Published by: Osaka Metropolitan University

■ Keywords: hybrid materials, crystalline solid, thermal conductivity

■ Abstract:

Scientists have discovered that, in the crystalline solid Ba1-xSrxAl2O4, a highly disordered atomic arrangement is formed in the AlO4 network at chemical compositions near the structural quantum critical point, resulting in both characteristics of crystalline and amorphous materials. This hybrid state can be created simply by mixing raw materials uniformly and heating them. These findings are expected to help with the development of hybrid materials for use in harsh environments, such as outer space, by applying the technique to a variety of materials.

Headline: Ultrathin solar cells promise improved satellite performance

■ Release Date: 2022.11.8

■ Published by: American Institute of Physics

■ Keywords: solar, radiation-tolerant, photovoltaic cell

■ Abstract:

As low Earth orbit becomes more cluttered, it becomes increasingly necessary to use middle Earth orbits, and radiation-tolerant cell designs will be needed. Making photovoltaics thinner should increase their longevity because the charge carriers have less far to go during their shortened lifetimes. Scientists propose a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. Compared to thicker cells, nearly 3.5 times less cover glass is needed for the ultra-thin cells to deliver the same amount of power after 20 years of operation.

Headline: Researchers develop a material that mimics how the brain stores information

■ Release Date: 2022.11.8

■ Published by: Universitat Autonoma de Barcelona

■ Keywords: magnetic material, ferroelectrics, magneto-ionic

■ Abstract:

Researchers have developed a magnetic material capable of imitating the way the brain stores information. The material makes it possible to emulate the synapses of neurons and mimic the learning that occurs during deep sleep.

Headline: Novel nanowire fabrication technique paves way for next generation spintronics

■ Release Date: 2022.11.9

■ Published by: Tokyo Institute of Technology

■ Keywords: silicon, nanowire, memory storage

■ Abstract:

The challenge of fabricating nanowires directly on silicon substrates for the creation of the next generation of electronics has finally been solved. Next generation spintronics will lead to better memory storage mechanisms in computers, making them faster and more efficient.

Headline: Magnetism or no magnetism? The influence of substrates on electronic interactions

■ Release Date: 2022.11.9

■ Published by: ARC Centre of Excellence in Future Low-Energy Electronics Technologies

■ Keywords: magnetism, energy-efficient, electronics

■ Abstract:

A new study illustrates how substrates affect electronic interactions in 2D metal-organic frameworks. With electronic properties tuneable by electrical charge, mechanical strain, and hybridization, such structures can be 'switched' off and on, allowing potential applications in future energy-efficient electronics.

Headline: Silicon nanochip could treat traumatic muscle loss

■ Release Date: 2022.11.9

■ Published by: Indiana University

■ Keywords: silicon, nanochip, nanotransfection

■ Abstract:

Technology that can change skin tissue into blood vessels and nerve cells also shows promise as a treatment for traumatic muscle loss.

Headline: Growing pure nanotubes is a stretch, but possible

■ Release Date: 2022.11.9

■ Published by: Rice University

■ Keywords: nanotubes, carbon, semiconductor

■ Abstract:

Researchers have published a new theory for making batches of carbon nanotubes with a single, desired chirality. Their method could simplify purification of nanotubes that are all metallic or all semiconductors.
