As the demand for smarter, smaller, and more energy-efficient electronics surges, the limits of conventional 3D semiconductors are becoming impossible to ignore. Now, researchers from Netaji Subhas ...

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 ...

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 ...

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 ...

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 ...
