Interlayer coupling provides an opportunity to observe new physics and a novel strategy for modulating the electronic and optoelectronic properties of two-dimensional (2D) van der Waals (vdW) ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

Rice University graduate student Lebing Chen used a high-temperature furnace to make chromium triiodide crystals that yielded the 2D materials for experiments at Oak Ridge National Laboratory's ...

The picosecond ultrasonics technique to probe atomic bonds and vdW forces in In 2 Se 3. In the experiment, blue-coloured pump laser pulses are shone on a flake of 2D material, and red-coloured probe ...

For all we know, the three dimensional world we see around us is really an illusion — one that’s actually in 2D. It’s a slightly unsettling idea, but it’s also one that physicists have been thinking ...

Suspended nanowires are highly favored force sensors. They are built with a very large aspect ratio (up to 5000) with a diameter and length of around 150 nm/100 μm, respectively, and effective masses ...

Why do we live in a universe with three dimensions of space and one of time—3+1 dimensions, as cosmologists would say? Why not some other combination, such as four dimensions of space or two ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. It's impossible to talk about football these days without talking about ...

Motility in three dimensions. Much of what we have learned about the physical and molecular mechanisms driving normal and cancer cell motility has come from in vitro studies using two-dimensional (2D) ...

The lack of a clinically viable method to track and direct cancer drugs to tumors is a big problem for targeted therapeutics. But a new ultrasonic method proposed by biomedical engineers from Qifa ...
