Here, we report on a novel class of fluorofoldamer-based artificial water channels (AWCs) that combines excellent transport rate and selectivity with structural simplicity robustness. Produced by facile one-pot copolymerization reaction under mild conditions, the best-performing channel (AWC 1) is an n-C8H17-decorated foldamer nanotube average length 2.8 nm pore diameter 5.2 Å. AWC 1 demonstrates ultrafast conduction 1.4 × 1010 H2O/s per channel, outperforming archetypal biological aquaporin...
Abstract Pathogen contamination of water has a massive impact on global human health. In particular, viruses pose unique challenges to treatment techniques due their small size and presence in as both individual virions when absorbed onto larger particles. Low-energy processes such media filtration are not capable completely removing owing size. Hence, less sustainable with high chemical or energy consumption disinfection, ultraviolet irradiation, membrane usually required. To overcome...
Nanoparticles (NPs) are present in the environment because of widespread use engineered nanomaterials and breakdown plastic waste. NPs can negatively impact human health, water treatment plants lack trains that optimized for NP removal. Thus, there is a crucial need low-cost, effective removal technology. We fabricated low-cost filter using diatomaceous earth (DE) cationic proteins extracted from Moringa oleifera (MO) seeds. These filters achieve 4.9 log palladium-doped greater than 2.9...
Lanthanides serve as essential elements for modern technology, playing critical roles in batteries, wind turbines, portable electronics, and energy efficient lighting. However, purifying lanthanides from ores recycling them end-of-life consumer materials is costly damaging to the environment due inefficient separation technologies. Lanthanide-lanthanide ion separations are challenging similarity their hydrated size, with commonly used methods limited single stage selectivities of ~ 2-3. Here...
Lanthanides serve as essential elements for modern technology, playing critical roles in batteries, wind turbines, portable electronics, and energy-efficient lighting. Purifying lanthanides from ores recycling them end-of-life consumer materials are costly damaging to the environment due inefficient separation technologies.

Viral contamination of drinking water due to fecal is difficult detect and treat effectively, leading frequent outbreaks worldwide. The purpose this paper report on the molecular mechanism for unprecedented high virus removal from a practical sand filter. Sand filters functionalized using extract Moringa oleifera (MO) seeds, (f-sand) filters, achieved ∼7 log10 removal. These tests were conducted with MS2 bacteriophage, recognized surrogate pathogenic norovirus rotavirus. We studied since it...
Biomimetic and bioinspired membranes have emerged as an innovative platform for water purification aqueous separations. They are inspired by the exceptional permeability (∼109 molecules per second channel) perfect selectivity of biological channels, aquaporins. However, only few successes been reported channel-based membrane fabrication due to inherent challenges realizing coherence between channel design at angstrom level development scalable that maintain these molecular properties...
Accessible and low-cost point-of-use technologies have significant potential to mitigate risk public health, particularly in areas with limited resources disaster scenarios. Natural cotton fibers functionalized water-soluble proteins from Moringa oleifera seeds (MO-cotton filter) are a promising technology at lab-scale demonstrated feasibility for pathogen removal water. Here, we showed the performance of MO-cotton filters under practically relevant conditions remove mammalian virus spiked...
Proper disinfection of harvested food and water is critical to minimize infectious disease. Grape seed extract (GSE), a commonly used health supplement, mixture plant-derived polyphenols. Polyphenols possess antimicrobial antifungal properties, but antiviral effects are not well-known. Here we show that GSE outperformed chemical disinfectants (e.g., free chlorine peracetic acids) in inactivating Tulane virus, human norovirus surrogate. induced virus aggregation, process correlated with...
Degradation of drag reducer polyacrylamide under high volume hydraulic fracturing (HVHF) conditions alters its polymer size, distribution and chemical composition, potentially affecting the toxicity treatability resulting wastewater.
Understanding the determinants of permeability and selectivity in biological channels serves two general purposes. It provides fundamental biophysical insights allows evaluation new membrane proteins artificial channel designs for development biomimetic separation membranes. This understanding relies on accurate ways to quantify unitary (single channel) solute solvent permeabilities. However, current research bioinspired membranes protein biophysics tends focus relative Further, many methods...

ABSTRACT Bioscientific research laboratories significantly contribute to global plastic waste production through their widespread use of products, such as single-use micropipette tips. However, biologically contaminated pipette tips must undergo several washing and sterilization steps before being reused or recycled. Grenova Solutions provides a decontamination station called TipNovus, which has been implemented by academic government labs reuse in sensitive biological assays. Despite this...
