Introduction to Purification Membranes

A proof-of-concept for the fabrication of novel anti-biofouling water purification membranes through the incorporation of a 2-aminoimidazole (2-AI) during membrane casting is presented.

Silk sericin is a globular protein whose resistance against fouling is important for applications in biomaterials and water-purification membranes.

Recent advances in graphene-based applications, such as sensors, transistors, energy storage, water purification membranes, solar cells, and elastomeric applications are highlighted.

Construction of an ultrathin GO layer on CNF offers a unique and efficient way to prepare highly functional, economical and scalable water purification membranes having significant advantage with respect to flux, mechanical stability and rejection of dyes compared to isotropic membrane with GO nanosheets randomly dispersed in the cellulose nanofibrous network.

, Li-ion battery electrodes), heaters, sensors, photoelectrodes for water splitting, water purification membranes, and self-cleaning films.

This study demonstrates that insertion of a diffusion barrier between the Pd and Nb-based substrates by surface corrosion is a viable approach to enhance the high-temperature stability of Pd-coated Nb–TiCo alloys, an aspect not widely explored in Nb-based hydrogen separation and purification membranes.

Screening and modification of bio-derived materials represent a cost-effective and environmental-friendly strategy for developing highly efficient water purification membranes.

Water-purification membranes with high water flux, excellent recycling ability, good anti-fouling property, wide range for different oil/water emulsions separation, and strong water-soluble dyes removal ability are highly desirable for water purification but still a challenge to be realized.

This has led to their growing utilization in water/wastewater treatment and environmental remediation applications, including water purification membranes, heavy metal removal, capacitive deionization, and bactericidal agents.

They are employed extensively in the biomedical field, including medicine, artificial organs, dentistry, prosthetic devices, bone repair, drug delivery systems, synthesis of biomolecules, and purification membranes.

Here, the possibility to separate hydrogen from the mixture of Natural Gas (NG) and hydrogen (NG+H2) with various NG concentrations using Pd, PdCu53 and PdAg24 hydrogen purification membranes is demonstrated.

In addition, considerations and strategies such as subsidiary gas injection, filtration, novel tolerant catalyst layers, purification membranes, etc.
