Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Micro-morphology and Properties of OMMT/PES/BMI Composites

open access: yesJournal of Harbin University of Science and Technology, 2019
Allyl compounds and polyether sulfone(PES) were used to modify bismaleimide. Meanwhile, organically montmorillonite(OMMT) was doped to prepare OMMT/PES/BMI multi-phase composites.

Cross-flow microfiltration applied to oenology: A review [PDF]

open access: yes, 2011
The cross-flow microfiltration applied to wine filtration has become a legitimate alternative to conventional filtration processes. However, membrane fouling which affects the operating costs and the plant maintenance, limits the widespread application ...

MXene‐Based Flexible Memory and Neuromorphic Devices

open access: yesSmall, EarlyView.
The unique two‐dimensional structure, excellent electrical conductivity, and diverse surface groups of MXenes have garnered significant attention. Coupled with their exceptional flexibility, MXene‐based devices hold immense potential for flexible memory and neuromorphic systems. This review comprehensively discusses the fundamentals of flexible devices,

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

open access: yesSmall, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

open access: yesSmall, EarlyView.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

Elastic properties of highly anisotropic thin poly(propylene) foams

open access: yes, 2004
In this letter, elastic properties of highly anisotropic cellular poly(propylene) films are reported. The material shows peculiar elastic properties compared to other foams in the literature. The data is displayed as the relative Young's modulus $E^*/E_s$

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Improved permeation performance and fouling-resistance of Poly(vinyl chloride)/Polycarbonate blend membrane with added Pluronic F127 [PDF]

open access: yes, 2014
The aim of this work was to prepare and characterize poly(vinyl chloride) (PVC)/polycarbonate (PC) blend membranes for use in ultrafiltration. Pluronic F127 was used as an additive to modify the membrane surface of the PVC/PC blended membranes. The PVC/

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.
