HKUST-1@silica aerogel composite pellets (HKUST-1@SiO) were prepared by the coupled sol-gel and water-in-oil emulsion method using supercritical CO drying. The structure and morphology of HKUST-1@SiO were characterized by X-Ray diffraction, scanning electron microscopy and low-temperature nitrogen adsorption. According to these data, the composite represents physically dispersed micron-sized domains of HKUST-1 in the silica aerogel pellets. It was shown that the HKUST-1@SiO pellets can be used as a catalyst for isomerization of styrene oxide to phenyl acetaldehyde in a continuous flow reactor. Graphical abstract: [ABSTRACT FROM AUTHOR]

Using ferromagnetic resonance method, we performed measurements of two-dimensional periodic arrays of disc-shaped cobalt particles with different diameters a=450 and 900 nm and the distance between them l=2 a and 3 a with temperature variation in the range T = 140 −300 K. The first derivative of the microwave absorption spectrum was registered. With the increase of T additional peaks on both sides from the main peak that move aside from it, all peaks show an increase of the intensity and a decrease of the width. Dependences of the resonance field on T shows saturation-like behavior with increasing temperature. They move to higher temperatures and show sharper behavior with a increase and l decrease, respectively. An increase of a leads to the intensity decrease and width increase of all three adsorption peaks. [ABSTRACT FROM AUTHOR]
