The trade-off between ionic conductivity and stability remains a major challenge in developing high-performance anion exchange membranes (AEMs). Herein, PPO-based AEMs with an appropriate degree of DABCO-C6 cross-linking and flexible multi-cation DTH side chains, denoted as PPO/DABCO-C6/DTH-y (y = 20–50), were prepared to construct continuous ion-conducting pathways. PPO/DABCO-C6/DTH-40 not only exhibits a high OH– conductivity of 95.75 mS cm–1 at 80 °C and retains 79.79% in 1.0 M NaOH at 80 °C for 600 h but also maintains a low swelling (9.82% at 80 °C) and high tensile strength (37.68 MPa). Raman analysis indicates that OH– transport is primarily governed by the Grotthuss mechanism, enhanced by high alkalinity. In water electrolysis, the PPO/DABCO-C6/DTH-40 achieves 390 mA cm–2 at 1.9 V (50 °C) and remains stable at 420 mA cm–2 (12 h). This study provides a new structural design for PPO-based AEMs, balancing high ionic conductivity with dimensional and chemical stability for practical water electrolysis.

Agricultural
waste peanut shells are rich in cis -diol flavonoid
luteolin (LTL). However, conventional separation
materials suffer from insufficient specific sites, binding limitations
only under alkaline environments, and poor anti-interference performance
in complex matrices. Herein, an integrated fabrication strategy combining
in situ polymerization in mesoporous soft confined space and teamed
boronate (TBA)-functional molecular imprinting technology is innovatively
proposed. The hierarchical substrate of GO@MS was covalently assembled
via a thiol–ene click reaction, and a boronate affinity-imprinted
polymer was grown confinedly inside mesoporous channels. The TBA molecular
group as a functional monomer would be used for specific recognition
of LTL under neutral conditions. As a result, the prepared MI-GO@MS@GLYMO-TBA
exhibits high binding capacity (61.78 μmol g –1 ) for LTL at 308 K under physiological pH (7.4), with an equilibrium
time of 360 min. In addition, MI-GO@MS@GLYMO-TBA could be recycled
six times with a slight loss of 8.00% in adsorption. Meanwhile, the
commercially available LTL with 85% purity could be easily enriched
and further extracted with high selectivity (up to 93.67%). Remarkably,
the purified LTL solutions displayed lasting antibacterial performance
against Staphylococcus aureus ( S. aureus ) with an inhibition zone of 12.15 mm. Therefore,
the MI-GO@MS@GLYMO-TBA nanocomposite could be potentially developed
as a feasible and efficient method to achieve the goals of green sustainable
chemistry for precise identification and separation of LTL from complex
samples from agricultural wastes.

Wearable shielding electronic skin is highly desirable
for protecting
humans from electromagnetic radiation. However, conventional wearable
electromagnetic interference (EMI) shielding materials still encounter
major challenges in simultaneously achieving high shielding effectiveness,
mechanical flexibility, and biocompatibility. Here, we report a flexible
biocomposite membrane fabricated through the synergistic assembly
of silk fibroin (SF) nanofibers and the two-dimensional conductive
material MXene. The SF nanofibers regulate the stacking and spatial
distribution of MXene lamellae via multiple hydrogen bonds, which
markedly enhances electromagnetic wave attenuation, interfacial coupling,
and oxidative degradability. The biocomposite membrane delivers an
EMI SE of 63.64 dB, higher than that of the pure MXene membrane (approximately
50 dB), and the biocomposite membrane achieves an SSE/ t value as high as 3.15 × 10 4 dB cm 2 g –1 across a broad frequency range of 8–26.5 GHz,
achieving outstanding EMI shielding performance together with oxidative
degradability in 2% H 2 O 2 and excellent cytocompatibility.
This study provides an avenue toward sustainable, high-performance
wearable EMI shielding materials.

Sugarcane bagasse (SB), a kind of renewable and low-cost
biomass
byproduct from the sugar industry, holds great potential to be processed
into environmentally friendly composites for plastic substitution.
Currently, the main strategy to develop SB-based composites is combining
SB and traditional fossil-based plastics, making the resulting composites
have poor degradability. Herein, an emerging and attractive dynamic
imine polymer (DIP) was combined with SB by hot-pressing to develop
an SB/DIP composite (SB/DIP). The resulting SB/DIP exhibited a tensile
strength of 43.1 MPa and Young’s modulus of 546 MPa. The SB/DIP
exhibited heat-induced repairability in its micromorphology and mechanical
properties because of the network exchangeable character of DIP. The
SB/DIP was fully decomposable and closed-loop recyclable due to the
chemical reversibility of dynamic imine bonds in DIP networks. Such
a high-performance SB/DIP composite represents a new type of sustainable
and environmentally friendly plastic substitute.

Precise regulation of the hydrophilic channels within
perfluorosulfonic
acid (PFSA) proton exchange membranes is critical for their performance.
Here, we present a high-performance composite membrane in which phytic
acid-functionalized graphene oxide (PhyGO) is introduced into the
PFSA matrix to reconfigure the hydrophilic channels. At an optimal
loading of 1 wt %, PhyGO nanosheets are well-dispersed in the PFSA
matrix, and their phosphate groups establish an additional hydrogen-bonding
network. This network bridges and reconfigures the original hydrophilic
channels into more continuous pathways for proton transport. Consequently,
the composite membranes exhibit enhanced proton conductivity (1.23
times at 80 ° C), improved dimensional stability (0.94 times at
80 ° C), suppressed hydrogen crossover (0.91 times), and increased
power density (1.21 times) compared to pristine PFSA membranes. Furthermore,
the composite membrane also demonstrates superior chemical durability,
which is attributed to the combined hydrogen-barrier effect and radical-quenching
ability of PhyGO nanosheets. In contrast, excessive PhyGO loading
leads to severe filler aggregation, disrupting the continuity of proton
transport channels and mechanical integrity, thus degrading the overall
performance. This work demonstrates that employing functionalized
2D nanomaterials to reconstruct the hydrophilic proton-conducting
pathways is an effective strategy for developing high-performance
composite membranes.

Selective conversion of cellulose into C 2 polyols
under
aqueous-phase conditions remains challenging due to the difficulty
in coordinating hydrolysis, C–C bond scission, and hydrogenation
while suppressing nonproductive side reactions. Herein, we report
an ultrasmall entropy-stabilized multimetallic PdPtRuCuNi nanocatalyst
supported on defect-rich nanostructured WO x that enables precise interfacial regulation of the interfacial functional
balance. Under relatively mild hydrothermal conditions, the nanocatalyst
achieves complete cellulose conversion with a high ethylene glycol
selectivity of 65.7%, significantly outperforming the corresponding
single-metal nanocatalysts. Spectroscopic and kinetic analyses reveal
an exceptionally low apparent activation energy, which originates
from the surface-assisted hydrolysis pathway constructed by the nanoscale
metal-oxide contact interface with superior interfacial wettability
and abundant oxygen vacancies at the nanointerface. Mechanistic studies
demonstrate that the electronically coupled multimetallic sites provide
an ultrahigh hydrogenation rate that effectively traps reactive C 2 fragments before they undergo rearrangement to organic acids.
This work identifies rational modulation of nanoscale interfacial
functional balance as a universal design principle to boost target
product selectivity and carbon utilization efficiency for aqueous-phase
biomass catalytic conversion.

Structural health monitoring (SHM) of carbon fiber-reinforced polymer (CFRP) composites requires sensing systems that are both highly sensitive and structurally compatible. Herein, a dual-mode self-sensing strategy is developed by constructing a perylene diimide/graphene oxide (PDI/GO) heterojunction-engineered interphase in carbon fiber (CF-PDI/GO)/epoxy (EP) composites through synergistic covalent bonding and π−π interactions, thereby simultaneously tailoring π-electron transfer channels and interfacial properties. Formed via π−π stacking between GO and PDI, the PDI/GO heterojunction shows a mechano-responsive fluorescence “off−on” behavior driven by efficient electron transfer via long-range electron delocalization. In contrast to CF-PDI, CF-PDI/GO exhibits quenched fluorescence alongside enhanced conductivity and chemical activity, causing enhancements of 222.9% in electrical conductivity, 82.5% in interfacial shear strength, and 123.9% in transverse fiber bundle tensile strength of CF-PDI/GO/EP composites (vs CF-desized/EP). Under mechanical stimuli, an obvious electrical resistance change is observed with fluorescence “switching-on” signals at damaged regions, which is attributed to breakage of long-range π-electron channels between CF and the PDI/GO heterojunction. Benefiting from its inherent self-sensing mechanism, electrical impedance tomography (EIT) is used for in-situ and real-time damage visualization with higher sensitivity compared to infrared thermography (IRT). This work presents a heterojunction-enabled interphase engineering strategy for simultaneously reinforcing and sensing CFRP composites, offering a pathway toward next-generation smart structural materials.

Boric acid groups, containing CO 2 -philic hydroxyl functionalities that exhibit strong affinity toward CO 2 molecules, play a pivotal role in enhancing the selective CO 2 adsorption and separation performance of microporous organic polymers. However, their electron-withdrawing character and existing synthetic limitations have hindered the straightforward incorporation of boric acid moieties into porous hyper-cross-linked polymer networks for efficient CO 2 capture. Herein, a series of novel hyper-cross-linked polymers were synthesized via a one-pot Friedel–Crafts alkylation reaction employing boric acid derivatives as rigid and functional building units. The resulting polymers, which undergo incomplete cyclization conversion from boric acid groups to boroxine during the polymerization, exhibited hierarchical porosity, with a BET surface area of 1465 m 2 g −1 , a micropore area of 1410 m 2 g −1 , a CO 2 uptake of 20.82 wt %, and a CH 4 storage capacity of 2.67 wt % at 273.15 K and 1.00 bar. Benefiting from isolated boric acid groups, in situ generated boroxine functionalities, and well-developed micropores, the materials exhibited a remarkable CO 2 /N 2 selectivity of 87.68 at 273.15 K under low-pressure conditions (<0.3 bar), as determined by Henry’s law initial slope analysis. Structural tuning of the boric-acid-based building blocks enabled fine control over porosity and CO 2 adsorption capacity, highlighting the role of molecular design in optimizing gas separation performance. Complementary theoretical simulations elucidated charge density distributions and electrostatic potentials, providing insight into structure–adsorption correlations. This study broadens the scope of functional building blocks accessible for constructing hyper-cross-linked polymers and offers new design principles for high-performance porous materials in selective CO 2 capture and separation.

Acidizing
systems are widely employed in the exploitation of carbonate
reservoirs. However, the reaction kinetics of conventional hydrochloric
acid are excessively rapid, and the penetration distance is limited.
To address these issues, a purely cationic thickening polymer, ADDD,
was designed and synthesized for ultrahigh-temperature reservoirs
based on supramolecular interaction principles. The electrostatic
repulsion between cationic groups alleviates the compression of the
polymer’s electric double layer by H + , while the
hydrophobic association structure imparts rigidity and thermal resistance
to the polymer. The substitution of dimethyl diallyl ammonium chloride
(DMDAAC) for the commonly used AMPS monomer further reinforces the
polymer backbone, significantly enhancing its heat resistance, acid
resistance, and compatibility with carbonate reservoirs. At 180 ° C
and a shear rate of 170 s –1 , the viscosities of
15 and 20 wt % ADDD gelled acids stabilized at 40 mPa·s and 35
mPa·s, respectively, after 120 min of shear treatment. The gelled
acid retained 45.83% of its viscosity after aging at 180 ° C for
4 h. Its corrosion rate on P110SS was only 9.38 g/(m 2 ·h),
corresponding to 9.73% and 15.27% of the rates observed for hydrochloric
acid and AE gelled acid at the same concentration, respectively. Under
conditions of 180 ° C and 300 rpm, the acid–rock reaction
rate of ADDD gelled acid was reduced to merely 12.5% and 50.68% of
those of hydrochloric acid and AE gelled acid, respectively. The residual
acid exhibited a viscosity as low as 1 mPa·s, and no obvious
precipitation was observed. After breaking with 0.05 wt % ammonium
persulfate at 180 ° C, the viscosity of the ADDD gelled acid dropped
to 1.5 mPa·s. The conformational differences between ADDD and
AE in acidic media were collaboratively elucidated through zeta potential
measurements and dynamic light scattering (DLS) analysis. Molecular
dynamics simulations combined with analyses of H + diffusion
coefficients, binding energies, and radial distribution functions
revealed that hydrophobic association and cationic electrostatic effects
synergistically enhance acid resistance and suppress acid–rock
reaction rates. Meanwhile, electrostatic repulsion effectively prevented
the incompatibility issues of the corrosion inhibitor that arise from
amide thermal degradation under high-temperature conditions. The acid-
and temperature-resistant thickener synthesized in this study provides
technical and theoretical support for the development of ultrahigh-temperature
carbonate reservoirs.

This paper reports the effect of
m-aminobenzoic acid-functionalized
modified fullerene (fC 60 ) doping on the insulation performance
of cross-linked polyethylene (XLPE) composites. By leveraging the
electron-induced effect of the fC 60 structure, uniform
electron capture onto the C 60 molecular orbitals is achieved.
Kelvin probe microscopy, DC conductivity, DC breakdown, dielectric
properties, differential scanning calorimetry, and quantum chemical
calculations were performed on the samples to analyze the insulation
performance of XLPE before and after modification. The results show
that the DC breakdown field strength of the XLPE composite material
with fC 60 added is 13.76% higher than that of pure XLPE.
Moreover, this composite material exhibits lower DC conductivity and
dielectric loss, with a slower and smaller rate of surface potential
attenuation. The sample’s crystallinity increases as its lamellar
thickness decreases. Quantum chemical calculations show that a potential
barrier forms at the interface between XLPE and the quantum-well fC 60 , uniformly dispersing electrons within the fC 60 molecular cage and effectively reducing the electric-field distortion
at the fC 60 -XLPE interface.

Accurately resolving trace acetone against the highly humid background of exhaled breath remains a central obstacle to non-invasive diabetes diagnosis. Here we develop a metal–organic framework (MOF)-conversion-induced prenucleation strategy for the controlled construction of Fe 2 TiO 5–δ (FTO) solid solutions. During the topological transformation of MIL-125(Ti), Ti-derived oxide nuclei form within the pores of a daughter Fe-based MOF, enabling the generation of FTO enriched with mixed-valence Fe 3+ /Fe 2+ and Ti 4+ /Ti 3+ centres and abundant oxygen vacancies. The optimized FTO-3.49 sensor selectively detects acetone across 30–90% relative humidity, reaches a detection limit of 100 ppb and distinguishes ppb-level acetone concentrations in simulated exhaled breath. This performance is underpinned by mixed-valence centres that limit water-induced hydroxyl accumulation and oxygen vacancies that create additional adsorption sites and strengthen acetone binding, as supported by spectroscopic and computational evidence. This defect–valence synergy enables stable acetone sensing under highly humid conditions and provides a materials-design route towards humidity-resilient metal-oxide sensors for breath-acetone analysis.

Lead-free halide double perovskites are attractive luminescent materials owing to their low toxicity and structural stability, but their white-light performance is often limited by weak long-wavelength emission and inefficient energy regulation. Herein, Sb 3+ single-doped and Sb 3+ , Mn 2+ co-doped Cs 2 NaLuCl 6 phosphors were synthesized by a hydrothermal method. Sb 3+ introduces broadband blue emission associated with localized excited states, while Mn 2+ incorporation produces orange-red emission through the 4 T 1 → 6 A 1 transition. The coexistence of these two emission components enables tunable dual-emission and single-host white-light generation. Time-resolved PL analysis confirms the shortening of the Sb 3+ -related lifetime after Mn 2+ incorporation, and the energy-transfer efficiency reaches 31.25% for the optimized Cs 2 NaLuCl 6 : 0.005Sb 3+ , 0.05Mn 2+ sample. Temperature-dependent PL and Arrhenius analysis reveal improved thermal-quenching resistance, with the activation energy increasing from 0.13777 to 0.21293 eV. The optimized phosphor-based WLED exhibits neutral-white emission with CIE coordinates of (0.3287, 0.3565), a CCT of 5688 K, and a CRI of 72.4. These results provide insight into emission regulation and energy-transfer dynamics in Sb 3+ , Mn 2+ co-doped Cs 2 NaLuCl 6 phosphors for proof-of-concept white-light and optical anti-counterfeiting applications.
