The unique physicochemical properties of hybrid hydrogels create broad opportunities for their application in oil and gas engineering. In particular, these systems can be effectively utilized for formation water shut-off, selective plugging of high-permeability channels, profile control, and reservoir permeability restoration. The present study focuses on the swelling mechanisms of a...

The increasing contamination of water resources by petroleum-derived pollutants, synthetic dyes, and toxic organic compounds has created an urgent need for efficient, versatile, and environmentally sustainable remediation technologies. Carbon-based materials have emerged as promising platforms for environmental applications owing to their tunable surface, high surface area, porous structures,...

The development of efficient, sustainable, and recyclable heterogeneous catalysts for multicomponent reactions is of considerable importance in view point of green and modern organic synthesis. In this study, nitrogen-doped carbon nanofibers (N-CNFs) were used as an efficient green catalyst for the Biginelli multicomponent reaction, providing a straightforward and environmentally friendly...

An early assessment estimated 10.36 million tonnes/year of plastic waste in the five littoral countries: Russia 7.15 million tonnes, Iran 1.8 million, Kazakhstan 950,000, Azerbaijan 290,000, and Turkmenistan 170,000 tonnes. About 425,000 tonnes/year were generated in coastal areas, with 58,000–155,000 tonnes/year entering the Caspian Sea. The 2019 Tehran Convention report lists coastlines of...

In this study, the methanolic extract of the aerial parts of Anthemis talyschensis was used to synthesize silver nanoparticles (AgNPs) via a simple and rapid biological method. The synthesized nanoparticles were characterized using UV-Vis spectroscopy; their shape, size, and morphology were examined via Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM); and their...
