Published Scientists make nanoparticles dance to unravel quantum limits
(via sciencedaily.com) Original source The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published It's not only opposites that attract -- new study shows like-charged particles can come together
(via sciencedaily.com) Original source A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, depending on the solvent and the sign of the charge. The study has immediate implications for processes that involve interactions in solution across various length-scales, including self-assembly, crystallization, and phase separation.
Published Umbrella for atoms: The first protective layer for 2D quantum materials
(via sciencedaily.com) Original source As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.
Published AI technique 'decodes' microscope images, overcoming fundamental limit
(via sciencedaily.com) Original source Researchers have developed a deep learning algorithm for removing systematic effects from atomic force microscopy images, enabling more precise profiles of material surfaces.
Published Building bionic jellyfish for ocean exploration
(via sciencedaily.com) Original source Researchers show how biohybrid robots based on jellyfish could be used to gather climate science data from deep in the Earth's oceans.
Published Turning waste into gold
(via sciencedaily.com) Original source Researchers have recovered gold from electronic waste. Their highly sustainable new method is based on a protein fibril sponge, which the scientists derive from whey, a food industry byproduct.
Published Better neutron mirrors can reveal the inner secrets of matter
(via sciencedaily.com) Original source Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS. The improved mirror has been developed by coating a silicon plate with extremely thin layers of iron and silicon mixed with boron carbide.
Published Researchers create new compound to build space-age antennas
(via sciencedaily.com) Original source In a first-of-its-kind development, researchers have created a new compound that can be used to 3D print telecommunication antennas and other connectivity devices. These 3D printed products, created by combining a two-dimensional compound called MXenes with a polymer, can be used as an alternative for metallic counterparts and can make a vast improvement in communication technology including elements such as antennas, waveguides and filters.
Published A bright idea for recycling rare-earth phosphors from used fluorescent bulbs
(via sciencedaily.com) Original source Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.
Published How molecular 'handedness' emerged in early biology
(via sciencedaily.com) Original source Chemists fill a major gap in origin-of-life theories.
Published Researchers develop novel method to photosynthesize hydrogen peroxide using water and air
(via sciencedaily.com) Original source Researchers have developed a microporous covalent organic framework with dense donor-acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide through the photosynthesis process with water and air.
Published Light stimulates a new twist for synthetic chemistry
(via sciencedaily.com) Original source Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more.
Published Vest can detect earlier signs of heart muscle disease
(via sciencedaily.com) Original source A reusable vest that can map the electric impulses of the heart in fine detail could detect abnormalities from a potentially fatal heart disease much earlier than is currently possible, a new study suggests.
Published Want fewer microplastics in your tap water? Try boiling it first
(via sciencedaily.com) Original source Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.
Published Nanocarrier with escape reflex
(via sciencedaily.com) Original source Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
Published New disease testing component facilitates lower-cost diagnostics
(via sciencedaily.com) Original source Biomedical researchers have developed a new, less expensive way to detect nuclease digestion -- one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
Published You may be breathing in more tiny nanoparticles from your gas stove than from car exhaust
(via sciencedaily.com) Original source Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new study has found.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Visual prosthesis simulator offers a glimpse into the future
(via sciencedaily.com) Original source Researchers have developed a simulator that enables artificial visual observations for research into the visual prosthesis. This open source tool is available to researchers and offers those who are interested insight into the future application.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
