A facile approach is proposed for the stabilization of gold nanoparticles within alumina matrix based on fast coprecipitation of colloidal gold and alumina sol in the supercritical carbon dioxide used as antisolvent. Acetylacetone was used as a stabi

Blowout resistance is measured using an air stream of fibrous sound-proof materials of three types, with fibers of various diameters. The dependences of the blowout resistance of studied materials on their density are experimentally defined. It is su

Based on the results of calibrator observations at 13.5-mm and 8.2-mm wavelengths in 1985 and 2005, the dependence of the effective area of the RT-22 CrAO RI antenna on ambient temperature and elevation was determined. The obtained results confirm a

Based on the 1964–1996 observations in the frequency range 0.325–90 GHz, we study peculiarities of the variability of the quasar OH 471 (z=3.4). The double-humped spectrum had peaks at frequencies near 1 and 20 GHz. The flux density of the low-fr

The 325-MHz observations of the quasar OH 471 (z=3.4) in 1985–1996 revealed variability of its radio emission. Over this period, its radio flux density increased by a factor of 1.6. A steep-spectrum radio source was identified $$2_.^\prime 5$$ nort

Within the framework of a multi-year program of dense interstellar gas studies, we performed a new series of observations at the CrAO RT-22 radiotelescope in July 1998 using an improved 3-mm wavelength receiving facility. An acousto-optical spectrum
