How black silicon, a prized material used in solar cells, gets its dark, rough edge      (via sciencedaily.com)     Original source 

Researchers have developed a new theoretical model explaining one way to make black silicon. The new etching model precisely explains how fluorine gas breaks certain bonds in the silicon more often than others, depending on the orientation of the bond at the surface. Black silicon is an important material used in solar cells, light sensors, antibacterial surfaces and many other applications.

Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits      (via sciencedaily.com)     Original source 

In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans and other creatures, with unknown potential health and ecosystem effects. One big focus of research: bottled water, which has been shown to contain tens of thousands of identifiable fragments in each container. Now, using newly refined technology, researchers have entered a whole new plastic world: the poorly known realm of nanoplastics, the spawn of microplastics that have broken down even further. For the first time, they counted and identified these minute particles in bottled water. They found that on average, a liter contained some 240,000 detectable plastic fragments -- 10 to 100 times greater than previous estimates, which were based mainly on larger sizes.

Using berry phase monopole engineering for high-temperature spintronic devices      (via sciencedaily.com)     Original source 

Spin-orbit torque (SOT), an important phenomenon for developing ultrafast and low-power spintronic devices, can be enhanced through Berry phase monopole engineering at high temperatures. In a new study, the temperature dependence of the intrinsic spin Hall effect of TaSi2 was investigated. The results suggest that Berry phase monopole engineering is an effective strategy for achieving high-temperature SOT spintronic devices.

Asbestos: The size and shape of inhaled nanofibers could be exclusively responsible for the development of pulmonary fibrosis      (via sciencedaily.com)     Original source 

The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study conducted on glass nanofibers.

High-performance stretchable solar cells      (via sciencedaily.com)     Original source 

Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.

Aptamers: lifesavers; ion shields: aptamer guardians      (via sciencedaily.com)     Original source 

Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as well as ability to inhibit specific enzymes or target proteins through three-dimensional binding. They also hold promise for swift diagnoses of colon cancer and other challenging diseases by targeting elusive biomarkers. Despite their utility, these aptamers are susceptible to easy degradation by multiple enzymes, presenting a significant challenge.

Molecules exhibit non-reciprocal interactions without external forces      (via sciencedaily.com)     Original source 

Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don t seem to follow this reciprocal law.

Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting      (via sciencedaily.com)     Original source 

Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.
