Graphene oxide (GO) possesses specific properties that are revolutionizing materials science, with applications extending from flexible electronics to advanced nanotechnology. A key method for harnessing GO's potential is its laser-induced reduction, yet the exact mechanisms - photothermal versus photochemical effects remain unclear. Herein, we discover dominant role of reactions in laser reduction GO under visible light, challenging prevailing assumption dominant. Employing a combination...
This work uses the direct current magnetron sputtering (DCMS) of equi-atomic (AlTiZrHfTa) and Si targets in dynamic sweep mode to deposit nano-layered (AlTiZrHfTa)Nx/SiNx refractory high-entropy coatings (RHECs). Transmission electron microscopy (TEM), field emission scanning (FESEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), photoelectron spectroscopy (XPS) are used investigate effect addition on oxidation behavior coatings. The Si-free nitride coating exhibits FCC...
In this study, we propose an approach to the synthesis of new biodegradable polymer materials based on renewable raw feedstock (betulin) and derivatives hydroxycarboxylic acids using a catalyst/catalytic system (γ-Al2O3, γ-Al2O3/TBHP) that is safe for health environment. The resulting polymers are linear thermoplastic undergo collapse upon melting in presence atmospheric oxygen. Moreover, these demonstrate non-toxicity towards range Gram-positive Gram-negative bacteria. polycondensation...

The growing accumulation of waste polyethylene terephthalate (PET) presents a significant environmental challenge requiring the development sustainable recycling methods. In this study, we propose novel approach for upcycling PET into bend resistive sensors through laser-assisted carbonization surface-grown Ni-BDC (BDC = 1,4-benzenedicarboxylate). fabrication process involves solvothermal formation homogeneous layer, followed by treatment with 405 nm laser system to create graphene-like...
Herein, it has been shown that betulin can be transformed into its biologically active oxo-derivatives (betulone, betulinic and betulonic aldehydes) by liquid-phase oxidation over supported silver catalysts under mild conditions. In order to identify the main factors determining catalytic behavior of nanosilver in oxidation, was deposited on various alumina supports (γ-alumina boehmite) using deposition–precipitation with NaOH incipient wetness impregnation methods, followed treatment H2 or...
