“…The decrease in the top layer was likely due to the presence of an increased number of hydrophilic groups in the modified membranes, which caused a more rapid separation of the polymer solution during phase inversion. [ 13,36 ] These results provided an explanation for the improved hemocompatibility of the Tio‐PES membranes from the aspect of surface and cross‐sectional morphology.…”

The contact between the dialysis membrane and blood can induce oxidative stress (OS) and thrombosis, causing oxidative organ damage and impaired toxin clearance. To date, the selection of anticoagulants has focused on mechanisms inhibiting white, but not red (erythrocytes) thrombus formation. In the present study, polyethersulfone (PES) membranes were modified with the antioxidant drug tiopronin, the physicochemical properties and dialysis performance of the Tio‐PES membranes were evaluated. The effects on erythrocyte thrombosis were evaluated in terms of erythrocyte morphology, prothrombotic properties (adhesion, aggregation, viscosity, sedimentation, and hemolysis), and fibrinogen‐erythrocyte interactions. The regular anticoagulant and antiplatelet properties were also assessed. Superoxide dismutase (SOD), malondialdehyde (MDA), plasma protein, and complement C3a were further determined. Finally, the biosafety of the Tio‐PES membranes was evaluated both in vitro and in vivo. The Tio‐PES membranes exhibited excellent physicochemical properties and improved dialysis performance. We found that the Tio‐PES membranes stabilized erythrocyte morphology, reduced erythrocyte prothrombotic properties, decreased FIB adsorption, and prevented red thrombus formation. In addition, the Tio‐PES membranes exhibited excellent antioxidant properties and showed biosafety in our primary toxicity studies. Thus, Tio‐PES membranes hold promise as novel, safe, and effective dialysis materials for potential clinical application.This article is protected by copyright. All rights reserved

“…Where EPLA is the total energy of the pure PLA microparticle, ESSZ is the total energy of the free SSZ molecule, and ESSZ/PLA is the total energy of the complex formed. The solvent effect according to the Polar Continuity Model (PCM) was chosen to evaluate the adsorption mechanism of SSZ on PLA in the chloroform phase, based on experimental studies [25,26]. The physicochemical properties of the interacting systems are also calculated based on the definition of quantum molecular descriptors (QMDs):…”

“…Different from complex technological process of traditional dissolving-casting-evaporation routine, the phase transformation method exhibits the significant advantages of high efficiency, simplicity, and pollution-free preparation process. [17][18][19] The phase transformation is achieved by changing the thermodynamic state of homogeneous polymer solution by nonsolvent. The homogeneous organic solution is transformed into a solidified polymer electrolyte with 3D network structure once proper water is added into above organic solution.…”

Solid polymer electrolyte‐based batteries show great promise because of their safe operating properties, wide voltage window and suitable flexibility. However, low ionic conductivity, low cation transfer number, weak oxidation/reduction resistance and low mechanical strength limit their implementation in Zn ion batteries. Here, w e developed a “polymer‐in‐salt” Zn2+‐conductive solid electrolyte (denoted as 70% salt‐SPE) constructed by a simple and fast phase transition method. The room‐temperature ionic conductivity and the transfer number of the 70% salt‐SPE reaches 1.6 mS cm−1 and 0.78, respectively. Meanwhile, the ZnF2‐rich inorganic/organic hybrid solid electrolyte interface is formed, and the stable voltage window reaches 9.35 V. In consequence, the Zn||Zn symmetric cell continuously cycles over 700 hours at current density of 2 mA cm−2 and the Zn||Cu symmetric battery runs with Coulombic efficiency of >99%. The Zn||MnPBA full battery delivers a discharge specific capacity of 109 mAh g−1 at room temperature and 190 mAh g−1 at 60 °C. Meanwhile, impressive cyclic stability of 6000 cycles with capacity retention of 80% is achieved, which originates from the effectively optimized ion transport action and dendrite‐free Zn plating/stripping.

Construction of a ternary system: a strategy for the rapid formation of porous poly(lactic acid) fibers

Abstract: Combining electrospinning technology with ESP-NIPS, using chloroform as a solvent and absolute ethanol as a nonsolvent, poly(lactic acid) porous fibres are prepared within 5–10 s. This preparation provides a new resolution for the rapid formation of porous polymer materials.
