Materials informatics reveals new class of super-hard alloys

Posted: 13 Jun 2019 12:37 PM PDT

A new method of discovering materials using data analytics and electron microscopy has found a new class of extremely hard alloys. Such materials could potentially withstand severe impact from projectiles, providing better protection for soldiers in combat.

Carbon-neutral fuels move a step closer

Posted: 13 Jun 2019 11:35 AM PDT

Chemists have developed an efficient process for converting carbon dioxide into carbon monoxide, a key ingredient of synthetic fuels and materials.

Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing

Posted: 13 Jun 2019 11:35 AM PDT

Using a new approach, researchers detected the elusive Majorana quasiparticle, notable for being its own antiparticle and for its potential as the basis for a robust quantum computing system, in a device built from a superconductor, small magnetic elements, and a topological insulator.

Concert of magnetic moments

Posted: 13 Jun 2019 09:10 AM PDT

Researchers have uncovered a new way how the electron spins in layered materials can interact.

Liquid gold on the nanoscale

Posted: 13 Jun 2019 09:10 AM PDT

Researchers have discovered what liquid gold looks like on the nanoscale -- and in doing so have mapped the way in which nanoparticles melt, which is relevant to the manufacturing and performance of nanotech devices.

Bitcoin causing carbon dioxide emissions comparable to Las Vegas or Hamburg

Posted: 13 Jun 2019 07:45 AM PDT

The use of Bitcoin causes around 22 megatons in carbon dioxide emissions annually -- comparable to the total emissions of cities such as Las Vegas or Hamburg.

Carbon-neutral fuel made from sunlight and air

Posted: 13 Jun 2019 07:31 AM PDT

Researchers have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions.

New quantum dot microscope shows electric potentials of individual atoms

Posted: 13 Jun 2019 07:31 AM PDT

Researchers have developed a new method to measure the electric potentials of a sample at atomic accuracy. The new scanning quantum dot microscopy method could open up new opportunities for chip manufacture or the characterization of biomolecules such as DNA.

People with mobility issues set to benefit from wearable devices

Posted: 13 Jun 2019 07:31 AM PDT

Researchers are working on a project to develop wearable rehabilitative devices that can help disabled people sit, stand and walk in comfort.

'Virtual biopsy' device to detect skin tumors

Posted: 13 Jun 2019 07:31 AM PDT

Using sound vibrations and pulses of near-infrared light, a scientist has developed a new 'virtual biopsy' device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.

Making the 'human-body Internet' more effective

Posted: 13 Jun 2019 06:52 AM PDT

Human body communication (HBC) uses the human body to transmit power and data, much like the internet. Because it's a smaller and closed network, it has the benefit of being more secure and power efficient. In a recent study, a group of Japanese researchers used an equivalent circuit model to examine how different parameters affect HBC transmission characteristics.

Small currents for big gains in spintronics

Posted: 13 Jun 2019 06:52 AM PDT

A new low-power magnetic switching component could aid spintronic devices.

Selective logging will not be enough to sustain timber production in Amazonia

Posted: 13 Jun 2019 06:52 AM PDT

Amazonian forests are unlikely to provide enough timber to meet current demand over the long term, even with the use of improved logging practices. That is a key finding of a new study.

Lack of suitable roads for bicycling

Posted: 13 Jun 2019 06:51 AM PDT

A researcher says a lack of suitable roads is a big reason why cycling participation rates in Australia and Queensland are so low.

Breathing new life into dye-sensitized solar cells

Posted: 12 Jun 2019 03:11 PM PDT

Researchers are poised to reboot the field of aromatic-fused porphyrin sensitizers for dye-sensitized solar cells, the most efficient solar efficient solar technology available at present.
