In this study we evaluated the potential use of hazelnut shell powder in the production of a composite material. Polystyrene was used as a polymer matrix. This work presents the results of modifying hazelnut powder particles to create a polystyrene shell on their surfaces.

- The study explores the creation of new palladium-based complexes with indium(III) and gallium(III) acetates to develop heterometallic carboxylate complexes.
- Two specific Pd-In complexes were successfully synthesized and characterized using advanced techniques like X-ray crystallography.
- The Pd-In complex demonstrated catalytic activity in selective hydrogenation reactions, while the Pd-Ga complex proved to be unstable under certain conditions.
Platinum acetate blue (PAB) of the empirical formula Pt(OOCMe)2.5±0.25, a byproduct in the synthesis of crystalline platinum(II) acetate Pt4(OOCMe)8, is an X-ray amorphous substance containing platinum in the oxidation state between (II) and (III).

As an additional source of nitrogen the media contain fermentative hydrolysate of the mycelial waste of manufacture of aminoglycoside antibiotics (tobramycin and apramycin). The use of the media provided a 20 to 50% decrease of consumption of soybean meal, an essential food raw material, and design of a low-waste technology for biosynthesis of tobramycin.
