Research team develops direct laser writing system for high-resolution, high-efficiency nanofabrication
Phys.org - 19 Dec 2022 23:52
Peripheral photoinhibition (PPI) direct laser writing (DLW) is a lithography technique used to fabricate intricate 3D nanostructures that are widely employed in photonics and electronics. PPI-DLW uses two beams, one to e...
Stresses and hydrodynamics: Scientists uncover new organizing principles of the genome
Phys.org - 19 Dec 2022 22:22
A team of scientists has uncovered the physical principles--a series of forces and hydrodynamic flows--that help ensure the proper functioning of life's blueprint. Its discovery provides new insights into the genome whil...
Lasers used to throw and catch single atoms for first time
New Scientist - 19 Dec 2022 21:58
Extremely cold atoms were thrown with one laser beam and caught with another. The technique could be used in quantum computing
