Graphical Abstract: The state of water in a polyacrylamide (PPA) gel has been studied by the 1H NMR spectroscopy. It is shown that the PAA gel can serve as a container for prolonged retention of the Enoxil preparation without changing its chemical composition. At the same time, the molecular structures of Enoxil bind strongly to polymer chains, probably due to the formation of hydrogen-bound complexes with amino and imino groups.

Graphical Abstract: Green synthesis of silver nanoparticles (AgNPs) using Lantana camara yellow flower extract via microwave irradiation and ultrasound methods was conducted. The research was aimed at evaluating the effect of the synthesis method and also the time of treatment during synthesis on the particle size and antioxidant and antibacterial activities of the AgNPs. Analysis of the nanoparticles was performed using UV-Vis spectroscopy, transmission electron microscope (TEM), particle size analyzer, and Fourier transform infrared spectroscopy (FTIR). The present results support the advantages of plant extract and the green method for the production of nanoparticles for further potential applications.

Graphical Abstract: New mononuclear six-coordinate lanthanide coordination compounds [Ln (HL)3Cl3] (HL = (2,2,2-trichloro-N-(dipiperidin-1-yl-phosphoryl)acetamideCCl3C(O)N(H)P(O)[N(CH2)5]2, carbacylamidophosphate (CAPh) type ligand) have been synthesized from non-aqueous solutions. The complexes have been characterized by elemental analysis, spectroscopic methods (FTIR, 1H- and 31P-NMR, UV-Vis). The structure of [Sm(HL)3Cl3] has been further confirmed by single crystal X-ray diffraction analysis.
