Special Issue Information

Dear Colleagues,

The impact of nanomaterials upon membrane science and technology continues to give an excellent argument to amplify the theoretical and experimental studies. Membranes and membrane processes represent the core high-technology domain in which nanomaterials have been capitalized for their entire physical, chemical, and technical-economic potential. Increasingly sophisticated membrane requirements such as: chemical and photochemical oxidation resistance; high selectivity; sensitivity to physical, chemical, and biological parameters; high flow at low pressures; and longer lifetime have led to the transition from classical material membranes to composite or liquid membranes based on reactive and/or functional nanomaterials.

This Special Issue aims to cover a broad range of subjects, from nanomaterials synthesis to the design and characterization of membranes, membrane processes, and technologies with nanomaterial integration.

We welcome the submission of full papers, communications, and reviews. Potential topics include, but are not limited to:

  • Membrane nanomaterials (nanoparticles, nanocarriers, functional and/or reactive nanospecies, etc,);
  • Membrane processes based on nanomaterials;
  • Membrane reactors and catalyst systems;
  • Selective separation and sensing;
  • Nanomaterial-based cleaning technologies;
  • Nanomaterial membrane applications.

The preparation of membranes from polymer solutions by the phase inversion method, the immersion—precipitation technique has proved since the beginning of obtaining technological membranes the most versatile and simple possibility to create polymeric membrane nanostructures. Classically, the phase inversion technique involves four essential steps: Preparation of a polymer solution in the desired solvent, the formation of the polymer solution film on a flat support, the immersion of the film in a coagulation bath containing polymer solvents, and membrane conditioning. All phase inversion stages are important for the prepared membrane’s nanostructure and have been studied in detail for more than six decades. In this paper, we explored, through an electrochemical technique, the influence of the contact time with the polymer film’s environment until the introduction into the coagulation bath. The system chosen for membrane preparation is polysulfone-dimethylformamide-aqueous ethanol solution (PSf-DMF-EW). The obtained nanostructured membranes were characterized morphologically and structurally by scanning electron microscopy (SEM) and thermal analysis (TA), and in terms of process performance through water permeation and bovine serum albumin retention (BSA). The membrane characteristics were correlated with the polymeric film exposure time to the environment until the contact with the coagulation bath, following the diagram of the electrochemical parameters provided by the electrochemical technique.

Nanolayer deposition(s) of Ag and AgC composite on a plastic substrate was used to design disposable stochastic sensors. Three shapes of nanocoatings were tested. The first shape was obtained by deposition of a nanofilm of Ag on the plastic material; the second shape was obtained by deposition of a composite AgC nanolayer on the plastic material; the third shape was obtained by nanolayer deposition of a composite material of AgC on the top of the Ag nanofilm deposited on the plastic material. α-Cyclodextrin was used to modify the active surface of the sensor. Wide linear concentration ranges were obtained as follows: for de-assay of α-amylase in whole blood: 1.00 × 10−7–1.00 × 103 U mL−1 and for the assay of α-amylase in saliva: 1.5 × 10−15–1.5 × 102 U mL−1. α-Amylase was reliably determined from whole blood and saliva samples using the proposed disposable stochastic sensors.
