Published Spontaneous curvature the key to shape-shifting nanomaterials
(via sciencedaily.com)
Original source 
Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
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 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 Slimming down a colossal fossil whale
(via sciencedaily.com)
Original source 
A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
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 Killer instinct drove evolution of mammals' predatory ancestors
(via sciencedaily.com)
Original source 
The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers suggest.
Published Researchers harness 2D magnetic materials for energy-efficient computing
(via sciencedaily.com)
Original source 
Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.
Published Graphene research: Numerous products, no acute dangers found by study
(via sciencedaily.com)
Original source 
Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.
Published New water batteries stay cool under pressure
(via sciencedaily.com)
Original source 
A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
Published An environmentally friendly way to turn seafood waste into value-added products
(via sciencedaily.com)
Original source 
Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.
Published Revolutionary breakthrough in solar energy: Most efficient QD solar cells
(via sciencedaily.com)
Original source 
A research team has unveiled a novel ligand exchange technique that enables the synthesis of organic cation-based perovskite quantum dots (PQDs), ensuring exceptional stability while suppressing internal defects in the photoactive layer of solar cells.
Published Angle-dependent holograms made possible by metasurfaces
(via sciencedaily.com)
Original source 
Scientists unveil metasurface technology, allowing for angle-dependent holograms.
Published Engineering a coating for disease-free produce
(via sciencedaily.com)
Original source 
Texas A&M researchers combine food-grade wax with essential oils to defend produce from bacteria.
Published Plastic recycling with a protein anchor
(via sciencedaily.com)
Original source 
Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. A research team has now introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent degradation. The catalyst consists of a specially constructed 'anchor peptide' that adheres to polystyrene surfaces and a cobalt complex that oxidizes polystyrene.
Published Panama Canal expansion rewrites history of world's most ecologically diverse bats
(via sciencedaily.com)
Original source 
In a new study, paleontologists describe the oldest-known leaf-nosed bat fossils, which were found along the banks of the Panama Canal. They're also the oldest bat fossils from Central America, preserved 20-million years ago when Panama and the rest of North America were separated from southern landmass by a seaway at least 120 miles wide.
Published New chip opens door to AI computing at light speed
(via sciencedaily.com)
Original source 
Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.
