The new hybrid composite materials for PEM fuel cell were synthesized by the UV polymerization of acrylic monomers (acrylonitrile, acrylic acid, ethylene glycol dimethacrylate) and a sulfo aromatic monomer, i.e., sodium styrene sulfonate, and the tet

The clathrate complex of hierarchical architecture was successfully synthesised by the intercalation of beta-cyclodextrin (β-CD) and molecular iodine (J2) in between the layers of five-fold expanded matrix of gallium selenide (GaSe). The obtained cl

In this work, we present findings on the syntheses and study of properties of InSe nanohybrid. The introduction of guest component in GaSe matrix leads to an increase in inhomogeneities, which is clearly confirmed by the strengthening of the low-freq
