Cubes outperform spheres as catalyst particles
To date, nanoparticles as catalysts for green hydrogen have been like rowers in an eight: researchers could only measure their average performance, but couldn't determine which one was the best. This has now changed following the development of a new.....»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»
Lunar dust dynamics: Unveiling the charging properties and particle behavior of Chang"e-5 samples in an electric field
A study published in Engineering has shed new light on the behavior of lunar regolith particles under the influence of an external electric field, a discovery that could revolutionize space exploration and lunar resource utilization. The research, co.....»»
New approach reveals details about aerosol properties from hard-to-sample areas in the atmosphere
The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Turbulent solar wind originates in the sun"s corona, study shows
Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic field, creating chaot.....»»
Advancing green chemistry: A tandem catalyst for efficient biomass conversion
The global demand for sustainable energy sources has intensified the search for environmentally friendly alternatives to fossil fuels. Biomass waste, a byproduct of various industrial processes, presents an untapped potential for the production of bi.....»»
These 3D-printed pipes inspired by shark intestines outperform Tesla valves
Prototypes control fluid flow in a preferred direction with no need for moving parts. Enlarge / Shark intestines are naturally occurring Tesla valves; scientists have figured out how to mimic their unique structure. (credit: Sara.....»»
Samsung Galaxy S25 Ultra could outperform the iPhone 16 Pro Max
Based on the recent benchmarks, it looks like the upcoming Samsung Galaxy S25 Ultra could outperform the iPhone 16 Pro Max. The post Samsung Galaxy S25 Ultra could outperform the iPhone 16 Pro Max appeared first on Phandroid. The iPhone 16.....»»
Quantum sensing approach captures nanoscale electrochemical evolution in battery
Battery performance is heavily influenced by the non-uniformity and failure of individual electrode particles. Understanding the reaction mechanisms and failure modes at nanoscale level is key to advancing battery technologies and extending their lif.....»»
Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice
It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics.".....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
Measuring moon dust to fight air pollution
Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to astronauts and valuable space.....»»
Nuclear theorists turn to supercomputers to map out matter"s building blocks in 3D
