Precise control over the nanofluid behavior of polyelectrolyte‐based membranes is a primary step toward understanding the structure‐morphology‐property relationships to ultimately determine the mass transfer characteristics. In this study, a high‐performance multistacked polyelectrolyte‐based cation exchange membrane (CEM) with a heterogeneous structure and versatile surface chemistry was developed to achieve selective ion conductance. The self‐assembled CEM can facilitate ion permeation with fluxes of 2.9 mol m−2 h−1 for K+ and 0.22 mol m−2 h−1 for Mg2+, reaching a mono/multivalent ionic selectivity of up to 13, outperforming mono/divalent fractionation when compared with state‐of‐the‐art membranes. Molecular dynamic (MD) simulations illustrated the ionic transport trajectory in hierarchical channels with angstrom‐scale cavities using multilayered CEMs. Both the experimental measurements and theoretical simulations indicated that ionic fractionation was associated with a large disparity in the energy barrier between mono/multivalent cations, which was the primary origin of the differences in the ion dehydration‐rehydration processes in the angstrom‐confinement membrane ion channels.

“…In the past two years, research has focused on exploring the potential of chitosan application, especially within the areas of the food industry [173][174][175], health care [176][177][178], and environmental application [179,180]. Through its numerous functional groups, chitosan allows for diverse forms of interaction, such as ionic hydrogen bonding, which is one of the reasons for its appeal in a variety of applications [181,182]. This study presented tremendous potential for researchers to develop an efficient and environmentally friendly methodology for chitosan extraction and production in innovative ways.…”

With a growing population, changes in consumerism behavior and trends in consumption in Indo-Pacific Asia, our seafood processing and consumption practices produce a large volume of waste products. There are several advantages in regulating and sustaining shellfish processing industries. The major advantage of waste management is that it leads to better conservation of natural resources in the long run. Shrimp shell waste contains useful biomaterials, which are still untapped due to inadequate waste disposal and solid waste management. Chitin, the major component of shell waste, can be extracted either chemically or biologically. The chemical extraction approaches, which use acids and alkali, could be an environmental burden. On the other hand, biological methods can be eco-friendly alternatives for shell waste management. In this review, recent trends in management of shellfish waste as sources of chitin, conversion of chitin into chitosan, economic aspects of waste treatment and application of chitosan will be discussed.

“…For example, the separation of lithium salts from seawater [18,19], recovery of heavy metal salts and acids from industrial wastewater [3,20,21], etc. For a successful separation of multiply charged metal salts from singly charged ones or acids, cation exchange membranes are used, selectively transporting singly charged cations and preventing the transport of multiply charged ones [3,22]. Monovalent cation exchange membrane permselectivity is provided by different physical phenomena such as the pore-size sieving effect, stronger electrostatic repulsion between the anion exchange surface layer and multivalent cations than monovalent cations, and the hydration energy difference caused by the different Gibbs hydration energy of cations [23][24][25].…”

A bilayer membrane based on a heterogenous cation exchange membrane with a homogeneous cation exchange layer and a polyaniline on its surface is prepared. The intercalation of polyaniline into the membrane with a homogeneous cation exchange layer is performed by oxidative polymerization of aniline. The influence of the homogeneous cation exchange layer and the polyaniline on the structure, conductivity, diffusion permeability, selectivity, and current–voltage curve of the heterogeneous cation exchange membrane is established. Membrane properties are studied in the HCl, NaCl, and CaCl2 solutions. The homogeneous cation exchange layer has a negligible effect on the transport properties of the initial heterogeneous membrane. The polyaniline synthesis leads to a decrease in the macropore volume in the membrane structure, conductivity, and diffusion permeability. The counterion transport number in the bilayer membrane is significantly reduced in a solution of calcium chloride and practically does not change in sodium chloride and hydrochloric acid. In addition, the asymmetry of the diffusion permeability and shape of current–voltage curve depending on the orientation of the membrane surface to the flux of electrolyte or counterion are found.
