Polyvinyl alcohol (PVA) is a widely used water-soluble polymer and usually processed in a form of aqueous solution and one of the most common application form of PVA products is film. Porous structure is often introduced to optimize the performance of the films, in which non-solvent induced phase separation (NIPS) is a widely adopted method to optimize the performance of polymer films for its convenient operation, energy efficiency and environmental friendliness. In this paper, PVA films were prepared by using NIPS method, in which the surface morphology of the film was determined by the preparation conditions. The surface morphology of the films prepared under different concentration of PVA aqueous solution, carbon nanotubes (CNTs) content ([[EQUATION]]) and crosslinker was explored. For the PVA/CNTs composite, the hydrogen bond network structure was gradually destroyed with the increase of [[EQUATION]], and the surface morphology of film changes from sponge-like structure to network-like structure and finally to droplet-like structure. It is revealed that the dense network structure (i.e. intermolecular hydrogen bonding network) within the aqueous solution determined the surface morphology transformation of the films. PVA NIPS film containing 1.5wt% of CNTs exhibits the best humidity sensitivity due to the fine equilibrium behavior of the two competitive parameters of thin polymer layer and high internal porosity. In addition, a KOH/PVA NIPS film was prepared by adding KOH electrolyte into ethanol, which exhibits wide humidity response range and short humidity response and recovery time. © 2024, The Authors.

Silver nanowires (AgNWs) hold great promise for applications in wearable electronics, flexible solar cells, chemical and biological sensors, photonic/plasmonic circuits, and scanning probe microscopy (SPM) due to their unique plasmonic, mechanical, and electronic properties. However, the lifetime, reliability, and operating conditions of AgNW-based devices are significantly restricted by their poor chemical stability, limiting their commercial potentials. Therefore, it is crucial to create a reliable oxidation barrier on AgNWs that provides long-term chemical stability to various optical, electrical, and mechanical devices while maintaining their high performance. Here we report a room-temperature solution-phase approach to grow an ultra-thin, epitaxial gold coating on AgNWs to effectively shield the Ag surface from environmental oxidation. The Ag@Au core-shell nanowires (Ag@Au NWs) remain stable in air for over six months, under elevated temperature and humidity (80 °C and 100% humidity) for twelve weeks, in physiological buffer solutions for three weeks, and can survive overnight treatment of an oxidative solution (2% H2O2). The Ag@Au core-shell NWs demonstrated comparable performance as pristine AgNWs in various electronic, optical, and mechanical devices, such as transparent mesh electrodes, surface-enhanced Raman spectroscopy (SERS) substrates, plasmonic waveguides, plasmonic nanofocusing probes, and high-aspect-ratio, high-resolution atomic force microscopy (AFM) probes. These Au@Ag core-shell NWs offer a universal solution towards chemically-stable AgNW-based devices without compromising material property or device performance.

Cigarette butt filter as membrane material with tannic acid and FeCl₃ additives for improve antifouling properties

Case Studies in chemical and Environmental engineering 2025年 11卷

Membrane fouling remains a critical challenge in wastewater treatment, particularly in applications involving oil-water emulsions. This study addresses this issue by fabricating antifouling membranes from repurposed cigarette filter waste, modified with tannic acid and FeCl₃ (ferric chloride) coatings. These modifications enhance membrane hydrophilicity, antifouling properties, flux recovery, and selectivity through an environmentally friendly approach. The membranes were prepared using the non-solvent induced phase separation (NIPS) method and subsequently coated through vacuum filtration. Key performance metrics included pure water flux, oil emulsion selectivity, and antifouling properties. The antifouling mechanism was attributed to the hydrophilic and protective layers formed by the tannic acid and FeCl₃ modifications, which reduced fouling and improved flux recovery. Characterization revealed that the tannic acid and FeCl₃ modifications created a hydrophilic layer with uniform pore distribution, leading to an oil rejection rate of up to 97 % and an increased flux recovery ratio of 85 %, compared to 65 % in unmodified membranes. The results highlight the potential of waste-derived membranes as a sustainable alternative for industrial wastewater treatment, aligning with the principles of circular economy and green chemistry. Future work should explore long-term stability, surface charge effects, and optimization of additive concentrations to enhance performance and antifouling efficiency further. © 2025 The Authors

AutoTemplate: enhancing chemical reaction datasets for machine learning applications in organic chemistry

Abstract: This paper presents AutoTemplate, an innovative data preprocessing protocol, addressing the crucial need for high-quality chemical reaction datasets in the realm of machine learning applications in organic chemistry. Recent advances in artificial intelligence have expanded the application of machine learning in chemistry, particularly in yield prediction, retrosynthesis, and reaction condition prediction. However, the effectiveness of these models hinges on the integrity of chemical reaction datasets, which are often plagued by inconsistencies like missing reactants, incorrect atom mappings, and outright erroneous reactions. AutoTemplate introduces a two-stage approach to refine these datasets. The first stage involves extracting meaningful reaction transformation rules and formulating generic reaction templates using a simplified SMARTS representation. This simplification broadens the applicability of templates across various chemical reactions. The second stage is template-guided reaction curation, where these templates are systematically applied to validate and correct the reaction data. This process effectively amends missing reactant information, rectifies atom-mapping errors, and eliminates incorrect data entries. A standout feature of AutoTemplate is its capability to concurrently identify and correct false chemical reactions. It operates on the premise that most reactions in datasets are accurate, using these as templates to guide the correction of flawed entries. The protocol demonstrates its efficacy across a range of chemical reactions, significantly enhancing dataset quality. This advancement provides a more robust foundation for developing reliable machine learning models in chemistry, thereby improving the accuracy of forward and retrosynthetic predictions. AutoTemplate marks a significant progression in the preprocessing of chemical reaction datasets, bridging a vital gap and facilitating more precise and efficient machine learning applicati

This study explores the potential of physically mixing individually targeted Doxorubicin (DOX)-loaded liposomes functionalized with folic acid (FA) and trastuzumab (TRA), combined with ultrasound (US) triggering, to enhance targeted breast cancer therapy. This research focused on synthesizing, characterizing, and evaluating DOX release, cellular uptake, and cytotoxicity of FA-PEG and TRA-PEG-modified liposomes mixed at different volume fractions. Low-frequency ultrasound (LFUS) and high-frequency ultrasound (HFUS) were employed to trigger DOX release. The study demonstrated that the sonicated-physically-mixed liposomes showed superior release performance (specifically the M75 group) and increased cellular uptake (specifically the M25 group) compared to individually targeted liposomes, highlighting their combined potential in breast cancer treatment.

Purpose This paper aims to reduce waste management and generate wealth by investigating the novelty of combining chicken feather fiber and bamboo particles to produce hybrid biocomposites. This is part of responsible production and sustainability techniques for sustainable development goals. This study aims to broaden animal and plant fiber utilization in the sustainable production of epoxy resins for engineering applications. Design/methodology/approach This research used two reinforcing materials [chicken feather fiber (CFF) and bamboo particles (BP)] to reinforce epoxy resin. The BPs were kept constant at 6 Wt.%, while the CFF was varied within 3–15 Wt.% in the composites to make CFF-BP polymer-reinforced composite (CFF-BP PRC). The mechanical experiment showed a 21% reduction in densities, making the CFF-BP PRC an excellent choice for lightweight applications. Findings It was discovered that fabricated composites with 10 mm CFF length had improved properties compared with the 15 mm CFF length and pristine samples, which confirmed that short fibers are better at enhancing randomly dispersed fibers in the epoxy matrix. However, the ballistic properties of both samples matched. There is a 40% increase in tensile strength and a 54% increase in flexural strength of the CFF-BP PRC compared to the pristine sample. Originality/value According to the literature review, to the best of the authors’ knowledge, this is a novel study of chicken fiber and bamboo particles in reinforcing epoxy composite.
