New material with wavy layers of atoms exhibits unusual superconducting properties
MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that c.....»»
The Rise of Color in 3D Printing
True multi-material machines are here — and they’re good! The post The Rise of Color in 3D Printing appeared first on Make: DIY Projects and Ideas for Makers......»»
Plant material on obsidian blades on Rapa Nui suggests settlers there visited South America and returned
A team of archaeologists affiliated with several institutions in Chile reports evidence that early settlers on the island of Rapa Nui sailed to South America, interacted with people living there and then returned. In their study, published in PLOS ON.....»»
An air-stable single-crystal layered oxide cathode based on multifunctional structural modulation
Sodium-ion batteries (SIBs) are considered a promising energy storage system due to their superior safety properties, low price, and plentiful sodium supplies, while the development of electrode materials plays a critical function in the performance.....»»
Hitting this stretchy, electronic material makes it tougher
Accidents happen every day, and if you drop your smartwatch, or it gets hit really hard, the device probably won't work anymore. But now, researchers report on a soft, flexible material with "adaptive durability," meaning it gets stronger when hit or.....»»
New archive of ancient human brains challenges misconceptions of soft tissue preservation
Soft tissue preservation in the geological record is relatively rare, and except where deliberate intervention halts the process of decay (like embalming or freezing), the survival of entire organs is particularly unusual. The spontaneous preservatio.....»»
Carbon-based supports for electrocatalysis under industrially relevant conditions
Carbon materials, due to their appropriate physicochemical characteristics such as high surface area, adjustable pore structure, variable morphology, and multifunctional surface properties based on chemical modifications, low cost, and ease of prepar.....»»
Operations begin to de-ice Euclid"s vision
A few layers of water ice—the width of a strand of DNA—are starting to impact Euclid's vision; a common issue for spacecraft in the freezing cold of space, but a potential problem for this highly sensitive mission that requires remarkable precisi.....»»
Is food waste the key to sustainable, plastic-free diapers and sanitary pads?
Once thrown away, disposable items such as diapers and sanitary pads can take hundreds of years to decompose, because their absorbent parts and waterproof layers contain plastics and other synthetic polymers. But now, researchers are replacing these.....»»
Supercomputer simulations of super-diamond suggest a path to its creation
Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth......»»
A simple, scalable method using light to 3D print helical nanostructures
A new fabrication process for helical metal nanoparticles provides a simpler, cheaper way to rapidly produce a material essential for biomedical and optical devices, according to a study by University of Michigan researchers......»»
Good news for gray whales: "Unusual mortality event" declared over
It was a worrisome few years for North Pacific gray whales, with hundreds washing up dead on shorelines along the West Coast leading to an estimated 30% decline in their population......»»
How DHX9 stress granules protect daughter cells from UV-induced RNA damage
During the process of cell division, new daughter cells inherit a mix of genetic material and other molecules from their mother cells. This inheritance includes both beneficial components, which can help them for a robust start in life, and potential.....»»
Researchers discover tightest arrangement of bilayer alkali metals between graphene layers
Researchers at AIST, in collaboration with Osaka University, Tokyo Polytechnic University, Kyushu University, and National Tsing Hua University, have developed a technique to insert alkali metals into the interlayers of graphene, which is a single la.....»»
Engineers manage a first: Measuring pH in cell condensates
Scientists trying to understand the physical and chemical properties that govern biomolecular condensates now have a crucial way to measure pH and other emergent properties of these enigmatic, albeit important, cellular compartments......»»
Animal hair structure changes from summer to winter to fend off freezing weather, researchers show
Unique adaptations allow wild animals to survive temperature extremes that would quickly kill an unprotected human. For example, certain animals can withstand bitterly cold weather, thanks to the insulating properties of the hollow hairs that make up.....»»
Why do tree frogs lay their eggs on the ground?
When it comes to laying eggs, tree frogs have some unusual habits. Instead of always laying their eggs on tree branches where they usually live, they often lay their eggs on the ground. But why would a tree frog do this, especially when it puts its e.....»»
Direct laser writing on halide perovskites: From mechanisms to applications
Metal halide perovskites have become well-deserved "star" materials among a variety of semiconductors owing to their excellent optoelectronic properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable ban.....»»
Conduction of catalytic properties from buried transitional metals to exposed inert main group metals
The electronic interaction between buried single transitional metal and adjacent aluminum atoms via metallic bonding can be well demonstrated......»»
Researchers prove fundamental limits of electromagnetic energy absorption
Electrical engineers at Duke University have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block.....»»
Photon-like electrons in a four-dimensional world discovered in a real material
Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have n.....»»
