Special Issue Information

Dear Colleagues,

Membranes are critical components for sustainable energy and the environment, and they hold promise for clean technology applications. They enable the transportation of ions and the selective separation of gases, and they comprise a vast panel of compositions and structures, including inorganic, organic, and hybrid membranes.

Scope:

In this symposium (https://www.european-mrs.com/membranes-energy-and-environment-emrs), we call for contributions on the synthesis, physical chemistry, properties, function, and performance of membranes, as well as their broad range of applications, including membrane technologies used for water treatment and desalination, separators used for fuel cells, batteries, electrolysers, membrane actuators, or gas separation membranes (including those for hydrogen and CO2.

Metallic and ceramic membranes are mostly used for gas separation, permeation, and high-temperature applications (such as solid oxide fuel cells).

Polymer membranes, especially ionomer membranes, are associated with low- and intermediate-temperature applications, including within the vast fields of water purification and desalination. Ionic membranes are particularly important for applications in energy storage and conversion, including separators used for metal batteries and polymer fuel cells.

This symposium will discuss various topics, from the preparation to the functional application of membranes. Contributions may include various techniques for the synthesis and shaping of membranes, their physicochemical properties and mechanisms, or their functional properties and processes. Studies on the performances of various applications and reports on composition/structure/property/performance relationships are particularly welcome.

Given the growing urgency for environmental and energy solutions, this meeting will cover the latest advances in membrane science, linking fundamental research with practical applications, and will provide an optimal venue for a lively exchange of information.

Potential topics to be covered are as follows:

  • Membrane synthesis;
  • Membrane characterization;
  • The physical chemistry of membranes;
  • Fuel cell and electrolyzer membranes;
  • Battery separators;
  • Membrane actuators;
  • Water purification and desalination membranes;
  • CO2, H2, and other gas separation membranes;
  • Catalytic membranes.

The combination of ion exchange membranes with carbon quantum dots (CQDs) is a promising field that could lead to significant advances in water treatment. Composite membranes formed by sulfonated poly(ether ether ketone) (SPEEK) with embedded CQDs were used for the detection and removal of heavy metal ions, such as lead and cadmium, from water. SPEEK is responsible for the capture of heavy metals based on the cation exchange mechanism, while CQDs detect their contamination by exhibiting changes in fluorescence. Water-insoluble “red” carbon quantum dots (rCQDs) were synthesized from p-phenylenediamine so that their photoluminescence was shifted from that of the polymer matrix. CQDs and the composites were characterized by several techniques: FTIR, Raman, UV/VIS, photoluminescence, XPS spectroscopies, and AFM microscopy. The heavy metal ion concentration was analyzed by inductively coupled plasma–optical emission spectroscopy (ICP-OES). The concentration ranges were 10.8–0.1 mM for Pb2+ and 10.0–0.27 mM for Cd2+. SPEEK/rCQDs showed a more pronounced turn-off effect for lead. The composite achieved 100% removal efficiency for lead and cadmium when the concentration was below a half of the ion exchange capacity of SPEEK. The regeneration of membranes in 1 M NaCl was also studied. A second order law was effective to describe the kinetics of the process. Full article
