Article Synopsis
  • Water treatment plays a crucial role in sustainability, with a focus on reducing wastewater volume through an osmotic process using mixed-matrix woven forward osmosis (MMWFO) membranes modified with a TiO/NaTiO (TNT) nanocomposite.
  • The study characterizes the TNT nanocomposite, revealing its unique crystal structure and surface morphology, and examines how varying TNT concentrations affect membrane performance and hydrophilicity.
  • Results indicate that the optimized MMWFO membrane (0.01 wt.% TNT) achieved the highest water flow and volume reduction with distilled water, outperforming other water sources like tap water, textile wastewater, and gray water in terms of permeation efficiency.

The activity of alginic acid as a cytotoxic agent was improved by structure modification using 4-aminophenol (4-AP) through condensation and polymerization processes. Then, silver nanoparticles were employed through doping to further enhance the cytotoxic activity of the modified polymer. The structure of the prepared materials was characterized by FT-IR, HNMR, UV spectroscopy, X-ray diffraction, and electron microscopy, and the thermal behavior of all synthesized materials was intensively studied.

Mixed matrix woven forward osmosis (MMWFO) membranes made of polyethersulfone (PES)/graphene oxide nanosheets (GO NSs) were made by inserting varying wt% ratios of GO NSs (zero to 0.1 wt%) into the PES matrix. A coated woven fabric material was used to cast the membrane polymer solution.

Polysulfanilic acid has a low efficiency for the photoelectrochemical (PEC) production of H from water splitting due to high recombination rate of charge and low electrical conductivity. Therefore, polyaniline was doped with polysulfanilic acid to form a copolymer and a blend to enhance its PEC heterogeneous catalytic performance. This was achieved through the improvement of visible light absorption and charge carriers' separation property.

Electrodeposition of silver, tin and their alloys from different aqueous electrolytes suffer from various environmental issues and deposits are affected by H evolution and metal oxide formation. In this work, these metals and their alloys are electrodeposited by cyclic voltammetry utilizing ionic liquids based on CHClNO (choline chloride) that permits deposit properties control. Both Ag and Sn concentrations in the ionic liquid were varied from 0.
