At its most a typical sports narrative records what happens in space and time. Alongside this traditional history of events there has emerged a research approach that might be called structural sports history. Its methods move in the world under the

Despite that significant efforts have been made in the development of time-integrated graphene-based detectors operating in vis/IR/THz ranges, little is known about coherent detection of THz pulses...

Root system health is a key factor for seedling quality and it is a prerequisite for the proper growth of seedlings after out-planting. If the seedlings are moved to freezer storage too early in the season, roots can be damaged and thereby the qualit

We demonstrate that the Joule heating of the volume Bragg grating recorded in chloride photo-thermo-refractive glass can be suppressed by bleaching the silver nanoparticles with intense ultrashort laser pulses. Measurement of the bleached grating ang

It is experimentally shown that irradiation of silver-containing silicate glass by IR femtosecond laser pulses leads to generation of free electrons in glass as a result of multiphoton ionization. Free electrons, being captured by charged molecular s

We report on the optical properties of volume Bragg gratings in chloride photo-thermo-refractive glass after femtosecond laser bleaching. We show experimentally that irradiation of the gratings with femtosecond laser pulses can expand their transmiss

The spatial light modulator together with the computer generated holograms can be used to shape laser beam to correspond for specific need of the micromachining task. Especially dividing the original laser energy to beam array enables high degree of

Here we consider the optical and the chemical effects of a phosphate buffered saline (PBS), to titanium (Ti) surfaces. Compound (Ti, TiO, TiO 2 and Ti 2 O 3 ) analysis was conducted for native surfaces as well as for ultra pure water exposed and for

Directional dependence of adsorbed human plasma fibrinogen (HPF) and human serum albumin (HSA) on highly ordered pyrolytic graphite (HOPG), on polished titanium (Tip), and on titanium with a light-induced periodic surface structure (TiLIPSS) was inve
