Innovation is the topic of discussion and debate for hundreds of years. In the 19th century economists and historians note that the acceleration of economic growth is the result of technological progress. The first observations on it suggest that eco

Plasma surface modification was used to fabricate graphene on the top of insulating diamond-like carbon films. It is shown that by a combination of pulsed argon plasma treatment and thermal annealing at 350 C it is possible to achieve crystallization

The depth profile of the complex refractive index of silicon ion (Si + ) implanted polymethylmethacrylate (PMMA) is studied, in particular PMMA implanted with Si + ions accelerated to a relatively low energy of 50 keV and at a fluence of 3.2 × 10 15

We study numerically and experimentally the propagation of pulsed singular beams, including dark crosses and optical vortices, in self-focusing nonlinear media, resulting in filamentation and supercontinuum generation. Our results show that the singu
