Published Unveiling the generation principles of charged particles 'trion' in 2D semiconductor
(via sciencedaily.com) Original source Researchers pioneer dynamic manipulation and the generation principles of trion at the nanoscale using tip-enhanced cavity-spectroscopy.
Published Ammonia attracts the shipping industry, but researchers warn of its risks
(via sciencedaily.com) Original source Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.
Published Scientists 'break the mould' by creating new colors of 'blue cheese'
(via sciencedaily.com) Original source Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.
Published Direct view of tantalum oxidation that impedes qubit coherence
(via sciencedaily.com) Original source Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
Published Magnesium protects tantalum, a promising material for making qubits
(via sciencedaily.com) Original source Scientists have discovered that adding a layer of magnesium improves the properties of tantalum, a superconducting material that shows great promise for building qubits, the basis of quantum computers. The scientists show that a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor. All three may increase tantalum's ability to hold onto quantum information in qubits.
Published A physical qubit with built-in error correction
(via sciencedaily.com) Original source Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.
Published Edge-to-edge assembly technique for 2D nanosheets
(via sciencedaily.com) Original source A research team develops edge-to-edge assembly technique for 2D nanosheets.
Published How leafcutter ants cultivate a fungal garden to degrade plants and provide insights into future biofuels
(via sciencedaily.com) Original source Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.
Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators
(via sciencedaily.com) Original source Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Key dynamics of 2D nanomaterials: View to larger-scale production
(via sciencedaily.com) Original source A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
Published Intensifying the production of high-value compounds from industrial waste
(via sciencedaily.com) Original source New research demonstrates how glycerol carbonate, a biosourced industrial additive, can be produced in record time using CO2 and a by-product of the cooking oil recycling industry. The process relies on a hybrid approach combining fundamental physical organic chemistry and applied flow process technology. Two industrial wastes are thus converted into glycerol carbonate, a biosourced rising star with high added-value.
Published Engineers unmask nanoplastics in oceans for the first time, revealing their true shapes and chemistry
(via sciencedaily.com) Original source Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems. In a new study, engineers have presented clear images of nanoplastics in ocean water off the coasts of China, South Korea and the United States, and in the Gulf of Mexico. These tiny plastic particles, which originated from such consumer products as water bottles, food packaging and clothing, were found to have surprising diversity in shape and chemical composition.
Published Scientists make breakthrough in quantum materials research
(via sciencedaily.com) Original source Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Machine learning guides carbon nanotechnology
(via sciencedaily.com) Original source Carbon nanostructures could become easier to design and synthesize thanks to a machine learning method that predicts how they grow on metal surfaces. The new approach will make it easier to exploit the unique chemical versatility of carbon nanotechnology.
Published Ambitious roadmap for circular carbon plastics economy
(via sciencedaily.com) Original source Researchers have outlined ambitious targets to help deliver a sustainable and net zero plastic economy. The authors argue for a rethinking of the technical, economic, and policy paradigms that have entrenched the status-quo, one of rising carbon emissions and uncontrolled pollution.
Published Decarbonizing the world's industries
(via sciencedaily.com) Original source Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research. The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions -- planet-warming gases that result in climate change and extreme weather.
Published Small yet mighty: Showcasing precision nanocluster formation with molecular traps
(via sciencedaily.com) Original source Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.
Published Some plastic straws degrade quicker than others
(via sciencedaily.com) Original source Not all plastics are created the same, and some last longer in the ocean than others. Scientists have been working for years to quantify the environmental lifetimes of a wide range of plastic goods to see which have the shortest and longest lifespans in the ocean. To determine what plastics persist in the ocean, the team tests different products in large tanks that recreate the natural ocean environment.
