Antibacterial calcite created with a multilayer polyelectrolyte coating method
… the mineral particles are coated with selected polyelectrolytes. A multilayer approach is employed to increase the coverage of the calcite surfaces and slow-down mineral dissolution. The polyelectrolyte multilayer significantly decreases the dissolution of the calcite, so the overall particle …

Lanthanide Functionalised gold nanoparticles as MRI contrast agents
… with the increased size of the AuNPs. Secondly, polyelectrolyte coating of charged Gd-loaded AuNPs surface also resulted in increase of relaxivity due to better immobilisation of the Gd3+ ions. Gold nanoparticles were also used as templates for nitroxide based redox sensitive MRI contrast agents. …

Capacitive deionization performance of bi-tortuous activated carbon electrodes coated with asymmetrically charged polyelectrolytes
… also coated with thin asymmetrically charged polyelectrolytes to improve ion-selectivity while maintaining the bi-tortuous (BT) macroporous channels. Under constant current operation, the equivalent circuit resistance in CDI cells operating with bi-tortuous electrodes was approximately 2.2 …

Structural and plasmonic properties of gold nanocrystals
… were undertaken using a platform based on polyelectrolyte coating of gold nanoparticles by layer-by-layer deposition. The reporter molecules are bound onto the surface of polyelectrolyte coated nanoparticles before trap coating them with an additional oppositely charged polyelectrolyte …

Design of advanced reverse osmosis and nanofiltration membranes for water purification
… we designed a new membrane system using a coating technique to modify membrane surface properties to avoid adsorption of foulants like humic acid. A layer of water-soluble polymer such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), polyvinyl sulfate (PVS) or sulfonated poly(ether ether …
