Understanding how specific atom sites on metal surfaces lower the energy barrier for chemical reactions is vital in catalysis. Studies on simplified model systems have shown that atoms arranged as ...

Israel gave details about its new powerful weapon, which has the capability to change aerial warfare. The weapon is capable ...

Researchers have discovered a powerful new way to shield atoms from losing quantum information, a long-standing hurdle in building reliable quantum technologies. By using a single, carefully tuned ...

At present, the combination of high peak power and near diffraction-limited beam quality is essential for high-power pulsed fiber laser systems combining nanosecond pulses with multi-kilohertz ...

In the work presented is the theoretical description of optimal focusing of extended laser beam at long distances (over 1km). It is shown that in general case the optimal focusing condition does not ...
