Mutating quantum particles set in motion

Posted: 08 Feb 2022 08:39 AM PST

In the world of fundamental particles, you are either a fermion or a boson but a new study shows that one can behave as the other as they move from one place to another.

Predicting the efficiency of oxygen-evolving electrolysis on the Moon and Mars

Posted: 08 Feb 2022 08:39 AM PST

Scientists have today provided more insight into the possibility of establishing a pathway to generate oxygen for humans to potentially call the Moon or Mars 'home' for extended periods of time.

Lotus effect: Self-cleaning bioplastics repel liquid and dirt

Posted: 08 Feb 2022 07:52 AM PST

Inspired by the always immaculate lotus leaf, researchers have developed a self-cleaning bioplastic that is sturdy, sustainable and compostable.

Using the universe’s coldest material to measure the world’s tiniest magnetic fields

Posted: 08 Feb 2022 07:52 AM PST

Using atoms only a few billionths of a degree above absolute zero, a team of researchers has detected magnetic signals undetectable by any other existing sensor technology.

Self-assembling and complex, nanoscale mesocrystals can be tuned for a variety of uses

Posted: 08 Feb 2022 07:46 AM PST

A research team has found the key to controlled fabrication of cerium oxide mesocrystals, according to a recent report. The research is a step forward in tuning nanomaterials that can serve a wide range of uses --including solar cells, fuel catalysts and even medicine.

Towards self-sensing soft robots with electrochemically driven pumps

Posted: 08 Feb 2022 05:50 AM PST

Soft robots have received much attention recently due to their adaptability and safety. However, the fluidic systems used in these robots continue to use pumps that are large, heavy, and noisy. Now, researchers report a fluid pump driven by electrochemical reactions that are simple, lightweight, silent, and enable self-sensing actuation, with potential applications in wearable technology and touch display devices.

Simulation training helps hone advanced surgical skills, international trial finds

Posted: 08 Feb 2022 05:50 AM PST

A large-scale study has found that simulation-based surgical training produced an increase of surgeons' skills for more complex surgeries.

Anti-odor coating is no washout

Posted: 08 Feb 2022 05:50 AM PST

For the first time, researchers have found a cost-effective and convenient way to apply a silver-based antimicrobial clear coating to new or existing textiles. Their method uses polyphenols, commonly found in food items notorious for staining clothes such as wine and chocolate. A range of textile types can be treated by the researchers' method, and items can be washed multiple times without losing the antimicrobial and therefore anti-odor property.

'Bionic' pacemaker reverses heart failure

A revolutionary pacemaker that re-establishes the heart's naturally irregular beat is set to be trialled in New Zealand heart patients this year.

Beyond sci-fi: Manipulating liquid metals without contact

Posted: 07 Feb 2022 02:29 PM PST

Research inspired by Terminator 2's shape-shifting, liquid metal robot sees liquid-metal electrical conductors manipulated in mid-air without contact. The liquid wires can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares using a small 'triggering' voltage and a magnet. The new technology has potential application in advanced manufacturing and dynamic electronic structures, augmenting other non-contact manipulation technologies such as acoustics or optical tweezers.

Research team's mask strategy passes muster

Posted: 07 Feb 2022 12:57 PM PST

During the early stages of the COVID-19 pandemic, a research team went looking for and found a way to make standard surgical masks better at keeping out small airborne droplets that might contain the SARS-CoV-2 virus.

Mechanical hearts can regenerate some heart tissue

Posted: 07 Feb 2022 12:56 PM PST

Mechanical hearts spur some regeneration in dormant parts of failing hearts, according to a pilot study that shows promise for developing regenerative heart therapies.

Chemists develop radical way to make it easier, more profitable to recycle plastic

Posted: 07 Feb 2022 10:58 AM PST

Very little of the plastic water bottles, milk jugs and yogurt cups we use gets recycled. But chemists now describe a radical method they used to transform tossed out plastic into a tougher, stronger material commonly used for food packaging. Through 'upcycling,' the method may make plastic easier -- and more profitable -- to recycle.

Researchers use tiny magnetic swirls to generate true random numbers

Posted: 07 Feb 2022 09:48 AM PST

Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing.

Jet stream models help inform US offshore wind development

Posted: 07 Feb 2022 09:48 AM PST

With the federal government planning to hold the largest sale of offshore wind farm leases in the nation's history, a new study could help inform the development of offshore wind farms by providing detailed models characterizing the frequency, intensity and height of low-level jet streams over the U.S. Atlantic coastal zone.

Columns designed from nanographenes

Posted: 07 Feb 2022 08:27 AM PST

Several layers of nanographenes stacked on top of each other: such functional elements could one day be used in solar cells. Chemists have now paved the way for this.

Nanowires under tension create the basis for ultrafast transistors

Posted: 07 Feb 2022 08:26 AM PST

Nanowires have a unique property: These ultra-thin wires can sustain very high elastic strains without damaging the crystal structure of the material. A team of researchers has now succeeded in experimentally demonstrating that electron mobility in nanowires is remarkably enhanced when the shell places the wire core under tensile strain.

Protons are probably actually smaller than long thought

Posted: 06 Feb 2022 12:44 PM PST

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists have now developed a method that allows them to analyze the results of older and more recent experiments much more comprehensively than before. This also results in a smaller proton radius from the older data. So there is probably no difference between the values - no matter which measurement method they are based on.
