The burning of fossil fuels produces carbon dioxide emissions, increased levels of which cause serious environmental problems. Therefore, the design and use of new materials as media for capturing carbon dioxide and other gases, such as hydrogen and methane, has attracted significant research attention. In this work, three metal complexes containing a fusidate moiety were synthesized and tested as storage media for gases. By reacting sodium fusidate and metal chlorides in boiling ethanol, the corresponding metal complexes were obtained with 69–76% yields. The fusidate moiety acts as a bidentate ligand with variable geometry (distortion octahedral, square planner, or tetrahedral) depending on the metal (manganese, copper, or zinc, respectively) it is associated with. The elemental composition of the metal complexes was confirmed via energy dispersive X-ray spectroscopy and their surface morphology was inspected via field emission scanning electron microscopy. The Brunauer-Emmett-Teller surface area of the metal complexes varied from 31.2 to 46.9 m2/g, with pore volume and diameters of 0.035–0.049 cm3/g and 3.02–3.18 nm, respectively. The gas uptake at 323 K for carbon dioxide, hydrogen, and methane depended on the metal, gas, surface pore volume, and pore diameter. Reasonable carbon dioxide uptake (6.3–7.2wt%) was achieved with fusidate metal complexes at high temperature and pressure, whereas hydrogen and methane slowly permeated throughout the complexes.

Poly(vinyl chloride) (PVC) is a common plastic that has many uses. Additives enhance the properties of PVC and enable its use in specific applications under harsh conditions. Therefore, several new tin complexes containing the fusidate unit were synthesized and tested as PVC photostabilizers. The reaction of sodium fusidate and appropriate tin chloride or oxide in boiling methanol provides the corresponding organotin complex in high yield. The structures and properties of the synthesized tin complexes were established using several analytical and spectroscopic tools. Also, the surface morphology of the complexes was inspected using various methods. The fusidate unit acts as either a monodentate (triphenyl and dibutoxide derivatives) or bidentate (dimethyl and dibutyl derivatives) ligand depending on the substitutes attached to the tin atom. The PVC was blended with tin complexes (0.5% by weight), and thin films were made and irradiated with ultraviolet (UV) light for a long time. The effect of tin complexes on PVC as photostabilizers was assessed using different methods. The tin complexes significantly reduce PVC photodegradation. The non-desirable changes in the irradiated PVC were minimal in the presence of additives compared to those observed in the blank film. The dimethyltin derivative, which had the highest surface area compared to the other complexes, was the most efficient additive to decrease the photodegradation of PVC film after irradiation. The tin complexes prevent photodegradation by acting as ultraviolet absorbers as well as scavengers for hydrogen chloride and peroxides.

The Titania nanotubes thin films have been prepared by electrochemical anodization of Ti foil at room temperature, then PdNPs and PtNPs doped on TiO2 nanotube arrays at different deposition ratios (0.3, 0.5wt%) were carried out by electroless deposition. The mean size, shape, elemental composition of the titanium dioxide nanotubes and platinum deposited on it were evaluated by different techniques such as Fourier Transform Infrared Spectrophotometer (FT-IR), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray (EDX), X-ray diffraction pattern (XRD),and Atomic Force Microscopy (AFM ) techniques. From the results indicate, these tubes are well aligned and organized into high-density uniform arrays. The SEM diameters of these TiO2 nanotubes 79 nm and tube lengths are about in the range 2-4 µm, while the diameters forPdNPs\TiO2NT and PtNPs\TiO2NT range from (84 to 102) nm.
