To tackle the challenges of high viscosity, poor fluidity, and low recovery rates in heavy oil, a novel comb-like polymer viscosity reducer (GO-Z) based on nanographene oxide (GO) was developed. GO was first functionalized with a silane coupling agent and then grafted with long-chain alkyl (C16DMAAC) and polyether (APEG-8) groups. The results show that GO-Z exhibited superior emulsification, dispersion, and viscosity reduction properties under microagitation conditions (simulating the low-shear conditions of real reservoirs), achieving over 94% viscosity reduction at a concentration of 0.3 wt %. Physical simulation flooding experiments further demonstrated that GO-Z effectively improved heavy oil recovery at various injection rates, with the highest increase reaching 11.61%. This study opens up a clear and promising path for the application of functionalized GO in the emulsification and viscosity reduction of heavy oil cold production.

The efficient recovery of heavy oil in hypersaline reservoirs (>100,000 mg·L–1 TDS) remains a critical challenge due to the rapid structural collapse of conventional hydrophobically associating polymers. Addressing this limitation, we propose a “High-Density Weak Hydrophobe” strategy. A novel amphiphilic terpolymer (AMDA) was synthesized via free-radical aqueous solution polymerization, featuring a remarkably high incorporation (14.3 mol %) of the short-chain, sterically bulky monomer diacetone acrylamide (DAAM). Unlike traditional polymers containing long-chain alkyl groups (e.g., C16-HMPAM) that undergo catastrophic “salting-out” and coiling at high salinity, AMDA constructs a dense yet reversible dynamic network, retaining over 81% of its viscosity at 90 °C in 100,000 mg·L–1 brine. This structural resilience enables the formation of ultrastable O/W emulsions, achieving a heavy oil viscosity reduction rate exceeding 95%. Core flooding experiments demonstrated an incremental oil recovery of 34.6% of the original oil in place (OOIP) at 65 °C. Furthermore, microfluidic visualization and zeta potential analysis revealed a synergistic EOR mechanism: beyond macroscopic mobility control, AMDA facilitates in situ emulsification and induces a wettability reversal from oil-wet to water-wet by establishing a robust electronegative hydration layer on the rock surface. This study validates the “High-Density Weak Hydrophobe” paradigm as a superior alternative to conventional strong-hydrophobe systems, offering a robust solution for enhanced oil recovery in harsh saline environments.

Electromagnetic waves endanger precision instruments and human health, driving the demand for multifunctional flexible transparent conductive films (FTCFs) with integrated electromagnetic interference (EMI) shielding and electric heating to ensure reliable microelectronic performance in extreme environments beyond conventional materials’ limits. However, current FTCFs based on carbon nanomaterials, metal nanowires, or 2D materials still suffer from insufficient oxidation resistance, weak adhesion to substrates, and performance degradation under complex conditions, limiting their practical deployment. To address these, we designed the films, which involved constructing silver nanowire/carbon nanotubes/silver nanoparticle (AgNW/CNT@Ag) conductive networks on polyethylene terephthalate (PET) via spray and spin coating, followed by transferring them into glycerol-modified, sodium alginate (SA)-poly(vinyl alcohol) (PVA) composite layers. This structure leverages AgNPs grafted on CNTs, forming resistor-capacitor-like configurations to enhance EMI shielding via improved electromagnetic wave absorption. The embedded design, combined with CNT coverage over AgNW, strengthens the adhesion and oxidation resistance by blocking oxygen. Additionally, SA-induced surface wrinkles boost conductivity and wave reflection, while the conductive network enables efficient Joule heating. The resulting film exhibits performance: 9.46 Ω/sq sheet resistance @ 57.7% transmittance, a figure-of-merit (FoM) of 6.31, an EMI shielding effectiveness of 31.42 dB, a saturation temperature of 93.1 °C at 6 V, a relative resistance change (RRC) of 0.92 after 60 oxidation cycles, and an RRC of 0.36 after 1000 bending cycles. This work provides a promising structural design and material strategy for FTCFs, advancing their commercialization in multifunctional electronic applications.

Two-dimensional (2D) perovskites are highly promising optoelectronic semiconductor materials, yet their integration into microdevices is hindered by the difficulty in simultaneously achieving high crystallinity, regular shape, uniform size, and good processability during the synthesis process. Here, we report a substrate-free, room-temperature antisolvent recrystallization strategy using a mixture of toluene and green alcohols to address this challenge. The core of our approach is antisolvent additive engineering, where alcohols such as isopropanol guide anisotropic growth of crystals, thereby enabling the large-scale production of uniform microplates. The versatility of this method is fully demonstrated in the preparation of 2D (PEA)2Pb(Br,I)4 and (BA)2PbBr4 perovskite microplates. Under the optimized toluene/isopropanol volume ratio (21:4), (PEA)2PbBr4 single-crystal plates with a uniform rectangular shape and an average lateral size of 9.4 μm can be produced, which exceeds the size of most previously reported 2D perovskite micro/nanosheets. Furthermore, XRD analysis reveals that the synthesized (PEA)2PbBr4 microplates exhibits excellent stability even after exposure to air for 16 weeks. In particular, the as-constructed photodetectors based on (PEA)2PbBr4 microplates demonstrate excellent performance, with a dark current of 6.69 pA, a responsivity of 1.21 A/W, a switching ratio of 20.5, a detectivity of 1.75 × 1012 Jones, and an external quantum efficiency of 400%. This work provides a scalable approach for fabricating uniform 2D perovskite microplates of diverse compositions, thereby facilitating the exploration of high-performance, low-cost and integrated optoelectronic microdevices.

Effective thermal management and electromagnetic interference (EMI) shielding are critical for the reliability of miniaturized electronic devices. However, developing multifunctional composites using sustainable, low-cost mineral fillers remains a challenge due to their intrinsically limited phonon transport and dielectric loss capabilities. In this study, we innovatively proposed and achieved the phase transformation of pyrrhotite from the monoclinic (mPyr) to the hexagonal (hPyr) structure at 450 °C for the first time. Unlike the mPyr, the hPyr phase possesses a more ordered and stable crystal structure, which significantly suppresses phonon scattering and enhances intrinsic thermal conductivity (TC). To validate this, hPyr was modified with polysulfide bonds and incorporated into a silicone rubber (RTV-2SR) matrix. At a loading of 35 wt %, the hPyr/RTV-2SR composite achieved a remarkable 625% improvement in TC (1.46 W/(m·K)) over pure RTV-2SR and a 18.7% enhancement compared to mPyr/RTV-2SR (1.23 W/(m·K)), proving the superiority of the phase transformation strategy. Simultaneously, the hPyr/RTV-2SR composite possessed a resistivity exceeding 1013 Ω·cm while delivering a high EMI shielding performance of 39.6 dB primarily attributed to absorption loss. The incorporation of conductive mineral phases combined with optimized filler distribution endowed the composite with effective EMI shielding capability. In addition, the stress–strain analysis revealed that the hPyr/RTV-2SR composite achieved a tensile strength of 2 MPa. This work presents a promising strategy for the high value utilization of vulcanized mineral tailings while contributing to the development of multifunctional and sustainable materials.

Development of efficient artificial light-driven ion pumps is crucial for solar energy harvesting, yet remains fundamentally constrained by severe carrier recombination in photoactive materials. To overcome this fundamental limitation, we design a carbon nitride-carbon nanotube composite membrane that utilizes an interfacial Schottky junction for enhanced charge separation. The charge-regulating behavior of Schottky junctions effectively inhibits photoinduced charge recombination, thereby augmenting charge density asymmetry across the membrane. The resulting robust built-in electric field significantly amplifies light-driven force beyond single-component systems. Under 200 mW cm–2 illumination, the composite membrane demonstrates exceptional ion pumping performance, enabling reverse ion transport against a 2000-fold concentration gradient. Compared to homogeneous carbon nitride membranes, it exhibits a 233% enhancement in gradient tolerance and a 293% increase in power output. This work presents a Schottky junction engineering strategy for high-performance light-driven ion pumps, paving the way for advanced solar energy conversion and optoelectronic applications.

The development of poly(lactic-co-glycolic acid) (PLGA)-based microsphere scaffolds with comprehensive osteogenic activity, hydrophilicity, mechanical strength, and biocompatibility remains a significant challenge. Here, we constructed a hexagonal mesoporous silica (HMS)/PLGA composite microsphere scaffold (HP). Subsequently, we further developed a polydopamine (PDA)-modified version of HP (PHP) by applying a PDA coating to its surface. Compared with HP, PHP exhibited improved compressive strength and hydrophilicity while maintaining desirable porosity. In vitro, PHP promoted BMSCs proliferation and osteogenic differentiation, upregulated osteogenic gene expression, and induced macrophage polarization toward the M2 anti-inflammatory phenotype. In a rat calvarial defect model, PHP significantly enhanced bone regeneration, as confirmed by micro-CT and histological analyses, and maintained elevated expression of BMP-2 and VEGF to support osteogenesis and angiogenesis. Immunostaining further demonstrated increased CD163 and decreased iNOS expression, indicating an immunomodulatory effect. All materials showed favorable biocompatibility. This work integrated the surface functionalization of PDA with the structural features of HMS, demonstrating that the ternary composite scaffold achieved simultaneous regulation of the immune microenvironment and osteogenesis, providing a promising strategy for clinically translatable bone repair materials.

Dry reforming of methane (DRM) is a promising route for the simultaneous conversion of CO2 and CH4; despite the effectiveness of C–H bond activation ability of Ni-based catalysts, they face serious challenges due to coking. Herein, two metal–organic frameworks (MOFs), NH2-MIL-53 and MIL-53 were loaded with Ni via impregnation and calcined at different temperatures to prepare Ni/Al2O3 catalysts. The results reveal that the Ni-based catalyst derived from NH2-MIL-53 possesses a higher specific surface area (SSA) due to the presence of –NH2 groups, which remarkably improved the dispersion of Ni. Additionally, the calcination temperatures are found to play an important role. Low-temperature calcination leads to weaker metal–support interaction (MSI) while high-temperature calcination results in lower specific surface area (SSA) and agglomeration of the active component Ni. The Ni/Al2O3 catalyst calcined at 850 °C exhibits moderate MSI and high SSA, leading to excellent catalytic activity (CH4 conversion ∼68%, CO2 conversion ∼80%) and stability (>50 h with coking ≈0.022 mmol C·gcat–1·h–1) at 750 °C with a GHSV of 96,000 mL/(gcat·h). The derived porous alumina restricts Ni sintering. In situ DRIFT results show that such a catalyst benefits the formation of key intermediate b-HCOO* due to high Ni dispersion. This work provides new insights and directions for optimizing the performance of MOF-derived catalysts.

The ongoing antimicrobial resistance seriously threatens current therapies for infectious diseases and calls for new antibacterial agents. Gold nanoparticles (Au NPs) are particularly attractive in terms of antibacterial therapies, benefiting from their abundant and engineerable surface chemistries. γ-Aminobutyric acid (GABA) is a nonantibiotic nonessential amino acid acting as an inhibitory neurotransmitter in the human body and has numerous health benefits. In this study, we repurposed GABA to combat multidrug-resistant (MDR) bacteria by presenting it on Au NPs. GABA-capped Au NPs (Au_GABA) possessed a broad antibacterial spectrum against both Gram-positive and Gram-negative bacteria, including MDR strains like carbapenem-resistant Enterobacterales (CRE) and methicillin-resistant Staphylococcus aureus (MRSA). The action mechanism of Au_GABA included oxidative damage to nucleic acids, caused by the promotion of intracellular reactive oxygen species (ROS), and influence on the cell membrane, which leads to disturbances in bacterial metabolism, transport, and biosynthesis. In vivo studies demonstrated the excellent therapeutic efficacy of Au_GABA in MDR bacteria-induced purulent subcutaneous infections. Our study provided a new candidate for the treatment of MDR bacterial infections and a new direction for the novel uses of amino acids.

Excessive nitrite poses potential threats to human health, making the convenient and accurate detection of nitrite anions (NO2–) critically important for practical applications. Two-dimensional (2D) metal–organic frameworks (MOFs) have attracted attention in the design and application of electrochemical sensors due to their unique structure. In this work, based on the 2D [Cd2(BPDC)2(1,4-bis)2]n (MOF1, 4,4′-biphenyldi-carboxylic acid = H2BPDC, 1,4-bis(imidazol-1-ylmethyl)-benzene = 1,4-bis) and acetylene black (AB), a novel electrochemical AB/MOF1/glassy carbon electrode (GCE) sensor is constructed and demonstrated for sensitive detection of NO2– in the solution. The research demonstrates that the AB/MOF1/GCE electrochemical sensor exhibits a wide linear response range (2–200 μM) and a low detection limit (5.7093 × 10–8 M), attributable to the synergistic effect of the selectivity contributed by the 2D MOF1 structure and the enhanced sensitivity provided by the AB. It demonstrated excellent selectivity, long-term stability, and reproducibility and can be successfully used for the detection of nitrite in actual samples with a recovery rate of 95.35–104.94%. This paper provides the synthetic application of electrochemical sensors and an effective detection method for carcinogen NO2– in the environment.

With the booming development of the lithium-ion battery industry, there is an urgent need to develop an effective recycling method for lithium iron phosphate (LiFePO4, LFP) cathode materials of spent lithium-ion batteries. Herein, a direct hydrothermal regeneration strategy for industrial LFP black mass using low-cost glucose as a multifunctional agent is proposed. Under hydrothermal conditions, glucose not only serves as a reductant to convert FePO4 back to the LiFePO4 phase and heal Li–Fe antisite defects but also in situ generates a uniform carbon coating via hydrothermal carbonization. The regenerated LFP cathode delivers a high specific capacity of 153.16 mAh g–1 at 0.1 C and exhibits outstanding cycling stability with 89.27% capacity retention after 300 cycles at 0.5 C. A comprehensive techno-economic analysis further reveals that this glucose-assisted hydrothermal route offers significant economic and environmental advantages over conventional methods, presenting a promising scalable solution for sustainable battery recycling.

Framework interpenetration is often considered detrimental to porosity in metal-organic frameworks (MOFs), yet it can rigidify lattices and create confined environments that enhance guest-responsive photophysics. Here, a subtle 9-position substituent change on fluorene-based dipyridyl ligands regulates interpenetration and ion-sensing behavior in a unified Zn(II) platform. Combining 9,9-diethyl-9H-fluorene-2,7-dicarboxylic acid (H2L1) with 4,4′-(9,9-diethyl-9H-fluorene-2,7-diyl)dipyridine (L2) or 2,7-di(pyridin-4-yl)-9H-fluorene (L3) affords two topologically identical frameworks with distinct interpenetration degrees: the 3-fold interpenetrated [Zn4(L1)4(L2)2]n (1) and the 4-fold interpenetrated [Zn4(L1)4(L3)2]n (2). Single-crystal X-ray analysis shows that 1 contains fully coordinated dinuclear paddlewheel clusters, whereas 2 features both fully and partially coordinated clusters, leaving exposed carboxylate oxygen atoms as accessible interaction sites. In aqueous media, compound 1 selectively detects Au3+ via fluorescence quenching with a 0.99 μM detection limit, while compound 2 shows multi-ion quenching toward Au3+, Ag+, and Cu2+ with detection limits of 2.42, 2.51, and 2.15 μM, respectively. These results establish a clear structure–property relationship linking subtle linker sterics to interpenetration degree, the saturation and presence of open sites on the clusters, and coinage-metal-dependent fluorescence quenching.
