Thermal properties of new 2D materials for microchips can now be measured well

Making ever smaller and more powerful chips requires new ultrathin materials: 2D materials that are only 1 atom thick, or even just a couple of atoms. Think about graphene or ultra-thin silicon membrane for instance.

Quantum electronics: Charge travels like light in bilayer graphene

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light ...

Physicists explain, and eliminate, unknown force dragging against water droplets on superhydrophobic surfaces

Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it's commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics ...

Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...

Evolution's recipe book: How 'copy paste' errors led to insect flight, octopus camouflage and human cognition

Seven hundred million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today's standards, the animal had a front and a back, a top and a bottom. This was a groundbreaking ...

Fast radio bursts: Research introduces a novel approach to characterize their behavior

Fast radio bursts (FRBs) represent the most intense radio explosions in the universe. Since the first discovery in 2007, FRBs have garnered significant attention, culminating in the 2023 Shaw Prize in Astronomy. With yet ...

Flowers may be more ancient than dinosaurs, but scientists can't agree on when they evolved

Flowers may look delicate—but flowering plants, what scientists call angiosperms, are one of the most successful evolutionary organisms on the planet. Including more than 350,000 known species, they dominate the ecological ...

Quantum crystal of frozen electrons—the Wigner crystal—is visualized for the first time

Electrons—the infinitesimally small particles that are known to zip around atoms—continue to amaze scientists despite the more than a century that scientists have studied them. Now, physicists at Princeton University ...
