Laser-induced forward transfer (LIFT) is a high-resolution direct-write technique, which can print a wide range of liquid materials without a nozzle. In this process, a pulsed laser initiates the expulsion of a highvelocity micro-jet of fluid from a thin donor film. LIFT involves a novel regime for impulsively driven free-surface jetting in that viscous forces developed in the thin film become ...

We review recent progress in the theory of relativistic jet production in AGN and Micro-quasars. The current popular model for launching, accelerating and collimating astrophysical jets is based on magnetohydrodynamics (MHD). AGN jets are most probably powered by energy extracted from either an accretion disk or a rotating Black Hole. A strong electromagnetic field in the central engine, couple...

A persistent, thin micro-nano sr beamed gamma jet may be ejected from BH and Pulsars, powered by ultra-relativistic electron pairs. These precessing and spinning γ jet are originated by Inverse Compton and-or Synchrotron Radiation at pulsars or micro-quasars sources. They are most powerful at Supernova birth blazing, once on axis, to us and flashing GRB detector. The trembling of the thin jet e...

We present the results of a long-term study designed to investigate nature micro-variability in blazars carried out primarily at Southeastern Association for Research Astronomy (SARA) observatories. analyzed data fifteen OVV quasars and BL Lac sources collected from 1995 2021. The set consists single-band light curves interspersed with multi-color observations. This paper reports over 900 night...

Development of nanotechnology during last few decades gave significant contribution to different areas of research especially in biomedical sciences and improved characteristics of many biomaterials allowing their commercial application [1,2]. One of the representative examples is the development of nanomedicine, a new field of medical research which opened the possibility for interactions betw...
