Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.

An international research team has determined that Troodon, a dinosaur very close to modern birds, was a warm-blooded animal (an endotherm), but had a reproductive system similar to that of modern reptiles. The scientists applied a new method which allowed for accurate determination of the temperature when the egg's carbonate shell was formed. Furthermore, the researchers showed that Troodon laid 4 to 6 eggs per clutch. As nests with up to 24 Troodon eggs had been found, the scientists conclude that several Troodon females laid their eggs in communal nests.

Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.

A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.

Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.

Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.

Graphene is the strongest of all materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010. Yet, many properties of the material and its cousins are still poorly understood -- for the simple reason that the atoms they are made up of are very difficult to observe.

Conditions mapped for the first time of polaron characteristics in 2D materials. TACC's Frontera supercomputer generated quantum mechanical calculations on hexagonal boron nitride system of 30,000 atoms.

A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.

Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.

Ice surfaces have a thin layer of water below its melting temperature of 0 degrees Celsius. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the phase transition (such as melting and freezing) temperature. Besides premelting and prefreezing, whether similar surface phenomenon exists as a precursor of a phase transition has rarely been explored. Scientists now propose that a polymorphic crystalline layer may form on a crystal surface before the crystal-crystal phase transition and names it pre-solid-solid transition.

A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials -- like a tailor altering a suit -- could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases and MXenes, with the potential of producing new materials with very unusual compositions and exceptional properties.

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.

A review of evidence from prior research provides new support for the possibility that the evolution of larger brains in some species was enabled through increased energy investment by parents in their offspring.

A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.

One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.

Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.
