Phytic acid (PA) induced graphene macrostructures were synthesized and investigated for the sorption characteristics and mechanisms of mercury. The as-synthesized graphene foam possessed large specific surface area and amphiphilicity. FTIR and XPS analysis revealed that the as-prepared graphene macrostructure retained oxygen-containing functional groups after hydrothermal reduction and also captured new phosphorus-containing groups because of the introduction of PA. Different experimental parameters, such as pH, PA fractions and contact time were applied to probe into the Hg(II) adsorption performance of as-synthesized macrostructure. Pseudo-second-order kinetic model and Langmuir isotherm model fitted well to the obtained sorption kinetic and isothermal data. The maximum adsorption capacity at pH = 7.2 for mercury was 361.01 mg/g. The dominant mechanisms for mercury removal were mainly ion exchange and surface complexation. Real application in river water and seawater exhibited very promising results, indicating its broad prospect in water purification .

To develop an efficient thrombolytic therapy approach that addresses the limitations of current fibrinolytic drugs, such as short half-life, weak thrombus specificity, and poor penetration ability, we constructed a NIR-triggered detachable nanoplatform (PA/UK@IcpLipo) using thin-film hydration method designed to integrate attack and defense mechanisms for thrombolytic therapy. This platform can actively identify thrombi by binding to GPIIb-IIIa receptors overexpressed on activated platelets. Upon NIR laser activation and interaction with thrombin in the thrombotic microenvironment, the thermosensitive liposomes ruptured, releasing PA/UK core for deep penetration into the thrombus. Our results showed that the PA/UK@IcpLipo nanoplatform efficiently promoted rapid thrombolysis under the action of UK (attack), followed by PA exerting an antiplatelet aggregation effect (defense). This dual-action approach significantly improved vascular reperfusion rates. The NIR-triggered detachable nanoplatform offered a promising solution for enhanced thrombolysis efficiency and reduced bleeding risk, addressing critical limitations of current fibrinolytic therapies.

Poly (amino acid)s-based hydrogels with high biological safety and natural antibacterial capabilities have significant clinical value in wound repair dressings. Poly ( γ -glutamic acid) (PGA) and ε -poly-lysine (EPL) are among the few poly (amino acid)s that are widely available and can be biosynthesized on a large scale. In this study, PGA and EPL were selected as backbone molecules, and the complex of protocatechuic aldehyde and iron (PA@Fe) with photothermal effects was introduced to prepare the poly (amino acid)s-based antibacterial wound repair gel PGA-EPL-PA@Fe (PEPF). The PEPF gel dressing exhibited excellent adhesive, antibacterial, antioxidant, and other multiple properties, significantly promoting wound healing in rats, indicating the high clinical application prospects of poly (amino acid)s-based dressings.

Developing an environmentally friendly material with dual functionality of corrosion monitoring and inhibition is crucial for reducing economic losses. Herein, dual-function phytic acid carbon dots (PA-CDs) were prepared with a hydrothermal treatment method for corrosion monitoring and inhibition. The as-prepared PA-CDs exhibited a distinct color change from brown-yellow to wine-red immediately in the presence of OH−, and H+can restore the color of the PA-CDs-OH−system from wine-red to brown-yellow. Inspired by the above phenomenon, a visible RGB-based colorimetric sensor was fabricated by combining PA-CDs coatings with the self-made RGB-sensing device to detect OH−/H+during metal corrosion. In addition, PA-CDs had excellent corrosion inhibitory properties for Q235 steel hanging sheets in hydrochloric acid solutions, and the corrosion inhibition efficiency reached 96.40%. The excellent corrosion monitoring and inhibition properties demonstrate the potential application of the PA-CDs in engineering practice.

Controllable design of ternary PNIPAM-PEGMA-PEI microgel with enhanced hydrophilicity and covalent anchoring • Direct embedding of microgels into polyamide Layer via interfacial polymerization • Long-Term anti-scaling performance with thermally triggered self-cleaning and permeance enhancement As a cutting-edge intelligent membrane material, temperature-responsive composite membranes can reversibly regulate the surface properties and pore size structure of the membrane according to changes in ambient temperature, demonstrating unique application potential in the field of high-temperature separation. In this study, we used fully rigid aromatic poly ( p -phenylene terephthamide) (PPTA) as the porous base membrane and designed a temperature-resistant macromolecule. By introducing hydrophilic poly(ethylene glycol) methacrylate (PEGMA) monomers into the PNIPAM-PEI system, we synthesized the PNIPAM-PEGMA-PEI ternary copolymer microgel, and directly embedded it into the surface separation layer of positively charged polyamide using interfacial polymerization to obtain high-temperature resistant PPTA/PA@[PNIPAM-PEGMA-PEI] nanofiltration membranes, achieving significant reduction in membrane surface contamination rates while maintaining temperature-sensitive regulation of membrane pore size. The membrane exhibited a 57.9% increase in pure water flux at 60 °C and achieved salt rejections above 97% for Na 2 SO 4 , CaCl 2 , and MgSO 4 (5 g/L) at 25 °C. During a 180 h test with periodic thermal transitions, permeance rose from 9.8 to 16.4 L·m −2 ·h −1 ·MPa −1 while retention remained above 89%. This heat-triggered cleaning and reversible pore-size regulation originate from the reversible chain collapse of PNIPAM above its LCST, providing a new strategy for designing highly permeable, regenerable, and anti-scaling nanofiltration membranes for high-temperature desalination and high-salinity wastewater treatment.

In this study, a multilayer PPTA/PA/PEMs composite nanofiltration (NF) membrane was fabricated through sequential processes. First, a polyamide (PA) separation layer was constructed on a Poly (p-phenylene terephthamide) (PPTA) substrate via interfacial polymerization (IP). Subsequently, polyacrylamide hydrochloride (PAH) and polystyrene sulfonic acid (PSS) were alternately deposited on the PA layer using layer-by-layer (LBL) assembly, forming polyelectrolyte multilayers (PEMs). The PAH-terminated membrane (M4.5) demonstrated 97% retention for CaCl 2 and 98% for methylene blue (cationic dye) at 25°C, while the PSS-terminated membrane (M3) achieved 98% retention for Na 2 SO 4 and 97% for eosin Y (anionic dye) under identical conditions. Thermal stability tests across 25°C–65°C revealed retention rates exceeding 90% for M3and M4.5. Prolonged operation of M4.5 with CaCl 2 solution at 65°C for 80 h resulted in minimal efficiency loss, confirming robust thermal resistance. This performance is attributed to the synergistic combination of the thermally stable PPTA and the multilayer-engineered PA-PEMs structure, which effectively suppresses pore deformation under thermal stress. This study presents a novel preparation strategy for heat-resistant composite NF membranes, demonstrating exceptional application potential in the treatment of conventional textile dyeing and printing wastewater under high-temperature conditions.

Polyamide (PA) based thin-film nanocomposite (TFN) membranes containing zeolitic imidazolate framework (ZIF) particles, denoted as PA (ZIF)-TFN membranes, were fabricated via interfacial polymerization (IP) between m-phenylenediamine (MPD) and 1,3,5-benzenetricarbonyl chloride (TMC). ZIF-8 particles were incorporated by direct dispersion into the oil-phase solution. Subsequently, the membranes were etched with xylenol orange disodium salt (XO) under acidic conditions to produce reverse osmosis (RO) membranes with improved water flux and salt rejection. These improvements were attributed to additional water-permeation channels and the sealing of non-selective interface defects. Solution pH, etching duration, and XO concentration also play roles in the structure and performance of the optimized RO membranes. After 12 h of etching, superior TFN/XO (12) RO membranes were obtained with rejection rate increased from (99.0% ± 0.2%) to (99.7% ± 0.1%), and water flux increased from (42.3 ± 0.9 L·m −2 ·h −1 ) to (65.1 ± 0.9 L·m −2 ·h −1 ). In addition, the membranes exhibited excellent boron removal rate, operational stability, and anti-pollution performance under conditions of 32,000 ppm NaCl and 55 bar.

The present study demonstrates a one-step preparation of a sulfonated coal–based solid acid catalyst (CFA 250 –PA–SO 3 H). The catalyst was derived from coal fly ash (CFA) by undergoing carbonization and sulfonation with concentrated 1,3–propanesulfonic acid. The reaction took place at a temperature of 120 °C for 3.5 h with a constant agitation speed of 100 rpm. The ratio of carbonized CFA 250 –PA to 1,3–propanesulfonic acid was 3:8 wt/wt. As a result, the catalyst surface had a relatively high density of acidic –SO 3 H sites attached. The mesoporous CFA 250 –PA–SO 3 H catalyst with an acid density of 9.336 mmol/g was synthesized by chemically treating CFA, a waste product of coal–burning power plants. Using phosphoric acid, the CFA was calcined at 250 °C and then sulfonated at 120 °C with 1, 3–propane sulfonic acid. The CFA 250 –PA–SO 3 H exhibited higher surface acidity and catalytic activity due to increased acidity and larger surface area (105 m 2 /g). The characteristics of the synthesized catalyst were determined using FT–IR spectroscopy, SEM images, TG analysis, X–ray photon spectroscopy (XPS), and N 2 –adsorption and desorption isotherm, and the acidity was determined by titration. The mesoporous CFA 250 –PA–SO 3 H catalyst was then used to esterify oleic acid in a catalytic activity test. During the esterification reaction performed under optimal conditions (ratio of diethyl carbonate (4.36 g) to oleic acid (2.82 g), 3.5 wt.% catalyst concentration, 100 rpm agitation speed at 82 °C), the CFA 250 –PA–SO 3 H catalyst exhibited high activity (94.50% ethyl oleate for 2 h) and it stable for up to five cycles of recycling. In addition, this catalyst could be used to replace conventional environmentally hazardous homogeneous liquid acids through a solid acid–based catalytic process. This evaluation demonstrates that the technology is a very promising approach for developing low-cost and environmentally sustainable energy sources.

2D Ruddlesden-Popper (RP) phase perovskite single crystals feature significant optoelectronic properties owing to their unique structural characteristics. Introducing an asymmetric electrode configuration on 2D layered perovskites is expected to exhibit interesting interfacial contact phenomena and greatly enhance their optoelectronic performance. Herein, 2D RP-phase perovskite (PEA) 2 PbBr 4 (PPB) single-crystalline microplates, with thickness ranging from ≈60 to ≈350 nm, are prepared by the liquid–air interfacial method. Asymmetric contact barriers are constructed with two different metal electrodes on the perovskite microplates to improve the photodetection performance and obtain a preferable self-powered photodetection capability. The optimized asymmetric barrier and excellent band alignment facilitate efficient photogenerated charge dissociation and extraction, boosting the biased photocurrent by 5.59 × 10 4 times compared to symmetric electrode devices. Crucially, by constructing contact barriers with two different metal electrodes, a preferable self-powered (PEA) 2 PbBr 4 photodetector is achieved. The asymmetric photodetector exhibits a high on/off ratio of 7.69 × 10 3 and maintains an ultralow dark current (3.28 × 10 −13 A) with high photocurrent (2.41 × 10 −9 A) in self-powered mode. This study highlights a simple and effective strategy using asymmetric electrodes to improve the performance of a 2D RP-phase perovskite photodetector, advancing the understanding of carrier transport dynamics and material-electrode contact behavior of 2D perovskites.

Developing efficient membrane technology for CO 2 capture has aroused wide interest for environment conservation and emission reduction. Developing facilitated transport membranes is a potential strategy for improving CO 2 permeance and CO 2 /N 2 selectivity synchronously, based on the reversible reactions among carriers and CO 2 molecules. The reaction activity can be optimized by tuning the carrier mobility due to the enhanced water-swelling capacity. Here, thin-film composite (TFC) membranes containing water-swelling carboxymethyl chitosan (CMC) chains were prepared via interfacial polymerization process, aiming to improve CO 2 separation performance. As-prepared TFC membranes with different CMC loading have exhibited different Turing nanostructures , such as corrugated structures, octopus-branched structures and nodular structures. Water can enhance the activity of carriers in reversible reaction for facilitated transport membranes. TFC membranes with CMC have exhibited the enhanced water-swelling capacity, showing high CO 2 permeance of 1278 GPU together with CO 2 /N 2 selectivity of 89. This work put forward a simple and effective method to tune the membrane structure and enhance the facilitated transport.

Polyamide thin-film composite (PA TFC) membranes are generally leverage in water purification, but the large-scale commercialization is hindered by high modifier synthesis costs and complex preparation processes. A hydrophilic amino acid derivative 2-amino-3-hydroxy-3-phenylpropanoic acid (AHPA) using natural amino acid as the precursor, which boasted the advantages of abundant sources, low cost, and renewability, was designed and synthesized via a one-step method and incorporated into PA TFC membranes through a two-step interfacial polymerization process. Comprehensive characterizations confirmed successful AHPA incorporation, enabled by reactive functional groups of the low-cost precursor, which regulated surface charge, enhanced membrane hydrophilicity, and diminished roughness. The AHPA-modified membranes revealed enhanced water permeability with MgSO₄ rejection of 98.97%, achieving a balance between functionality and cost-effectiveness. Molecular dynamics (MD) simulations revealed that enhanced antifouling performance stemmed from synergistic hydration layers and electrostatic interactions. Long-term stability tests demonstrated consistent water flux and salt rejection, with superior organic pollutant removal for textile wastewater. This economical, scalable strategy based on low-cost precursors bridges lab-scale modification and industrial application, providing a feasible route for mass-producing high-performance water treatment membranes.

Moreover, the l -cysteine (LC) has an effect on diameter of [email protected] nanoparticles, which enables nanoparticles have size-controlled spherical morphology and good colloidal stability. The hemolysis assay and cytotoxicity assessment verified the good biocompatibility of [email protected] Moreover, our [email protected] nanoparticles could not only exhibit appealing PTT efficiency, but also achieve excellent CT/PA dual-mode imaging effect. The histological evaluations suggested the negligible toxicity of [email protected] in vivo . This is the first time to our knowledge that multifunctional [email protected] nanoparticles were prepared by an ingenious one-step method. This work not only highlights a one-step strategy that simplified the complex synthesis of [email protected] nanoparticles, but also provides insight for further biomedical application of “all-in-one” theranostic agent.
