Journal ArticleDOI
A review of water treatment membrane nanotechnologies
TL;DR: In this article, a semi-quantitative ranking system was proposed considering projected performance enhancement (over state-of-the-art analogs) and state of commercial readiness, while commercial readiness was based on known or anticipated material costs.
Journal ArticleDOI
A review on nanomaterials for environmental remediation
TL;DR: Nanomaterials in various shapes/morphologies, such as nanoparticles, tubes, wires, fibres etc., function as adsorbents and catalysts and their composites with polymers are used for the detection and removal of gases (SO2, CO, NOx, etc.), contaminated chemicals (arsenic, iron, manganese, nitrate, heavy metals, etc.).
Journal ArticleDOI
Nanoparticle Aggregation: Challenges to Understanding Transport and Reactivity in the Environment
TL;DR: This review briefly covers aggregation theory focusing on Derjaguin-Landau-Verwey-Overbeak (DLVO)-based models most commonly used to describe the thermodynamic interactions between two particles in a suspension.
Journal ArticleDOI
Antifouling membranes for sustainable water purification: strategies and mechanisms
TL;DR: This review will first introduce the major foulants and the principal mechanisms of membrane fouling, and then highlight the development, current status and future prospects of antifouling membranes, including ant ifouling strategies, preparation techniques and practical applications.
Journal ArticleDOI
Fabrication and characterization of novel antifouling nanofiltration membrane prepared from oxidized multiwalled carbon nanotube/polyethersulfone nanocomposite
TL;DR: In this paper, the authors describe the preparation, characterization and evaluation of performance and antifouling properties of mixed matrix nanofiltration membranes, which are prepared by acid oxidized multiwalled carbon nanotubes (MWCNTs) embedded in polyethersulfone as matrix polymer.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.

Silver nanoparticles as antimicrobial agent: a case study on E. coli as a model for Gram-negative bacteria
Ivan Sondi,Branka Salopek-Sondi +1 more
TL;DR: These nontoxic nanomaterials, which can be prepared in a simple and cost-effective manner, may be suitable for the formulation of new types of bactericidal materials.
Journal ArticleDOI
A mechanistic study of the antibacterial effect of silver ions on Escherichia coli and Staphylococcus aureus.
TL;DR: The existence of elements of silver and sulfur in the electron-dense granules and cytoplasm detected by X-ray microanalysis suggested the antibacterial mechanism of silver: DNA lost its replication ability and the protein became inactivated after Ag(+) treatment.
