The practical deployment of Zinc oxide (ZnO) photoanodes for photoelectrochemical (PEC) water splitting is severely impeded by rapid photogenerated carrier recombination and sluggish oxygen evolution reaction (OER) kinetics. Herein, we elucidate a synergistic structural engineering strategy integrating interstitial boron (B) doping, Type-II heterojunction construction, and coherent grain boundary regulation to tailor high-performance B-ZnO@ZnS nanorod arrays. Comprehensive characterizations corroborate that B-doping introduces abundant oxygen vacancies to modulate the electronic band structure, while the coherent B-ZnO/ZnS interface establishes a robust built-in electric field, thereby facilitating bulk charge separation and accelerating interfacial hole transfer. Consequently, the optimized photoanode exhibits a remarkable photocurrent density of 1.054 mA cm −2 at 1.23 V vs. RHE (representing a 1.67-fold enhancement over pristine ZnO) and a substantial cathodic shift in onset potential to 0.24 V. Notably, in situ ATR-IR spectroscopy captures the dynamic evolution of key *OOH intermediates, corroborating an adsorption evolution mechanism (AEM) where the multidimensional engineering significantly ameliorates the energy barrier for intermediate formation. This work offers a pivotal paradigm for designing durable and high-efficiency photoelectrodes via precise defect and interface manipulation.

Electrochemical energy conversion reactions are central to sustainable energy technologies, yet their efficiency at industrially relevant current densities is often constrained by mass-transfer limitations. Here, we introduce a periodic flow field strategy for enhancing mass transfer based on a geometrically periodic microstructure that induces spatially varying velocity fields and wall shear oscillations within the pores, generating a coherent convective contribution to otherwise diffusion-dominated transport. To implement this concept, we design hierarchical ordered interconnected porous nickel electrodes with long-range order, tunable structural periods and scalable centimeter-scale fabrication, serving as a general electrocatalyst support. The resulting architecture alleviates mass-transfer constraints across multiple electrochemical reactions. As a representative example, the NiFe-modified electrode delivers a current density of 7 A cm −2 for the oxygen evolution reaction at 25 °C with an overpotential of 393 mV, while an anion-exchange-membrane water electrolyzer sustains 1 A cm −2 at 1.68 V for 1083 h at 60 °C. We also construct a lightweight flexible device for portable oxygen and hydrogen production with efficient operation under fluctuating solar power.

Therapeutic drug monitoring (TDM) of mitoxantrone (MIT) is essential for balancing efficacy and toxicity, yet current methods are limited by complex pretreatment, long turnaround times, and matrix interference. Herein, we developed a SERS sensor based on a pectin/AgNPs@CMC/CS/PAAM composite hydrogel for separation-free detection of cationic anticancer drugs in plasma. Fabricated via one-step UV photopolymerization, the hydrogel's dense network provides size-sieving to exclude plasma proteins, while abundant carboxyl groups confer a strong negative surface charge for selective electrostatic enrichment of positively charged drug molecules. This dual mechanism enhances specificity toward cationic analytes in complex matrices. Using MIT as a model, the sensor achieved 82.6%–101.7% recoveries in 10% plasma, a detection limit of 4.7 × 10 −10 M, and excellent reproducibility. Requiring only simple dilution, this platform offers a practical and ultrasensitive tool for TDM of cationic drugs in combination chemotherapy.

Achieving stringent boron compliance in seawater desalination
has
long depended on energy-intensive multipass reverse osmosis (RO) with
alkaline dosing, creating a trade-off between energy consumption and
water quality. This work breaks this bottleneck by developing a hybrid
single-pass multistage (HSPM) system with selectivity-optimized loose
RO membranes. Tailoring commercial RO membranes into high-flux variants
via a 5 h controlled chlorination achieves an optimal balance, whereas
an extended 20-h modification causes an impractical 24.1-fold increase
in boron passage. Mechanistic analysis reveals that the 4-fold increase
in apparent activation energy ( E a ) for
B(OH) 4 – transport at pH 11 fails to fully
offset the intrinsic loss of steric selectivity under neutral conditions.
To overcome this material-level limitation, a multidimensional performance
map identifies the operational sweet spot of the HSPM system, enabling
membranes with moderate boron rejection and high water permeance to
meet the 1.0 mg L –1 threshold via multistage blending
and energy recovery. Coupling the 5 h chlorinated membrane with an
optimized 3-stage configuration theoretically yields a ∼42.5%
energy saving versus conventional two-pass RO. This research establishes
a novel paradigm for application-specific membrane selection and process
synergy, offering a scalable, low-carbon blueprint for desalination
and water reuse.

CsPbX 3 (X = I, Br, Cl) perovskite quantum
dots (PQDs)
are promising for optoelectronic applications owing to their tunable
bandgap, high photoluminescence (PL) quantum yield, and narrow emission
bandwidth. However, CsPbBr 3 PQDs exhibit a large Stokes
shift (>155 nm) and are mainly excited by near-ultraviolet light
(∼365
nm), resulting in substantial energy loss and limiting their compatibility
with blue light-emitting diodes (LEDs) excitation. Herein, Sr 2+ /Cl – codoped CsPbBr 3 PQDs embedded
in zinc borosilicate (ZBS) glass powders were developed to regulate
the band structure. Sr 2+ incorporation significantly enhances
PL performance. Notably, CsPb 0.5 Sr 0.5 Br 3 PQDs exhibit ∼1.6 times higher PL intensity than undoped
samples with a slight red-shift (∼5 nm). Meanwhile, the bandgap
of CsPb 0.1 Sr 0.9 Br 3 PQDs is widened
to 3.12 eV compared to 2.36 eV for CsPbBr 3 . Totally different
with undoped PQDs, the excitation peak of CsPb 0.1 Sr 0.9 Br 3 PQDs covers the desired blue-violet region
in the range of 400–480 nm and the maximum peak is located
at 414 nm, which displays a narrow Stokes shift of 106 nm. Further,
Cl – ions substitution in Sr-doped host materials
enables the blueshift of the PL emission from 521 nm (green light)
to 448 nm (blue light) via bandgap engineering accompanied by ultranarrow
Stokes shift of ∼34 nm for CsPb 0.1 Sr 0.9 BrCl 2 sample. The Sr-doped PQDs embedded in ZBS glass
also demonstrate excellent water resistance, retaining ∼96%
of their initial PL intensity after immersion in deionized water for
more than 60 days. Thus, the ultrastable PQDs glass powders can be
effectively excited by the blue-violet light chip (410 nm-460 nm)
via bandgap engineering possess and demonstrate promising application
potential in color-conversion display devices, wide-color-gamut backlight
systems and screen-printable emissive display films.

A hydrogel SERS platform requiring no pretreatment has been developed. • The LOD for DOX and MTO were as low as 3.4 × 10 −8 M and 3.6 × 10 −9 M. • Machine learning achieved a 100% identification for DOX and MTO plasma samples. Rapid quantitative detection and classification of trace drugs directly in complex biological fluids are crucial in modern analytical chemistry. This paper proposes a label-free, interference-resistant smart surface-enhanced Raman scattering (SERS) sensing strategy. A machine learning-assisted Au@Ag/C-CNF/PEGDA hydrogel SERS sensor is developed for monitoring and identifying anthracycline anticancer drugs in plasma. Addressing the susceptibility to contamination and oxidation inherent in conventional SERS sensors, this sensor leverages the pore-trapping effect and nanoparticle encapsulation properties of hydrogel. This approach not only eliminates macromolecular interference but also maintains a high signal output of 71.05% for the internal Au@Ag SERS probe after 50 days. Leveraging the electrostatic interactions of carboxylated cellulose (C-CNF), the sensor exhibits excellent signal reproducibility with detection limits as low as 3.4 × 10 −8 M for doxorubicin (DOX) and 3.6 × 10 −9 M for mitoxantrone (MTO). Furthermore, this study employed machine learning models for high-dimensional feature extraction of SERS data, achieving up to 100% classification accuracy for DOX and MTO in spiked plasma samples. This approach holds promise as a robust solution for clinical drug concentration monitoring and species identification, potentially advancing precision treatment strategies in clinical practice.

The detection of hazardous contaminants such as heavy metal ions and pesticide residues in water is essential for safeguarding environmental safety and public health. In this study, boron and nitrogen co-doped carbon dots (B,N-CDs) were synthesized via a one-step hydrothermal method using sodium citrate, urea, and boric acid as precursors. The as-prepared B,N-CDs demonstrated good water solubility, uniform dispersion, a maximum fluorescence emission at 445 nm, and reasonable stability. A fluorescence sensing platform based on B,N-CDs was developed for the sequential detection of Fe 3+ and phoxim using an “on-off-on” mode. The fluorescence of B,N-CDs is efficiently quenched by Fe 3+ through a static quenching mechanism (SQE); subsequent addition of phoxim restores the fluorescence due to competitive binding of phoxim with Fe 3+ . The detection limits for Fe 3+ and phoxim are 3.46 μM and 0.5 mg/L, respectively. In spiked environmental water samples, satisfactory recoveries of 82.7%–95.2% for Fe 3+ and 97.5%–112.0% for phoxim were obtained, with relative standard deviations (RSDs) below 15% ( n = 5). This study presents a promising platform for monitoring Fe 3+ and phoxim in aqueous environments.

With the advancement of high-power-density electronic components such as 5G and AI chips, traditional thermal management materials have shown limitations in process-ability, durability, functionality and reliability. Developing flexible composite phase change materials that combine high thermal conductivity, excellent thermal storage capacity, and good thermal management is extremely crucial. Thus, this study constructed a novel flexible phase change film with interconnected thermal conductive framework by innovatively utilizing flexible polyvinyl acetate (PVA) bonding with boric acid (BA) through hydrogen bonds. Thermochromic ink and molten PEG8000 were also infiltrated and synergistically interconnected into the cross-linking porous structure of PVA/BA, forming multiple function units. These units thereby established a continuous three-dimensional flexible network. As the PEG8000 content was 45 wt%, this composite phase change film exhibited a thermal conductivity as high as 0.7417 W·m −1 ·K −1 , and a phase change latent heat of 72.31 J·g −1 . It simultaneously maintained outstanding reliable cycling performance, excellent thermochromic performance and good flexibility. Thermal management demonstrated that the flexible film could significantly reduce the operating temperature of batteries, offering promising applications in thermal management of electronic equipment. This research also provided an effective solution for the preparation of flexible thermally conductive phase change films.

Synthesized the metal-free B and N co-doped porous carbon (B X NPC) catalysts. • Promoting •OH generation via B doping on B 50 NPC revealed by theoretical calculations. • •OH and 1 O 2 oxidation synergistically enhanced refractory antibiotics removal. • Treating actual pharmaceutical factory wastewater with a low energy consumption. • Excellent detoxification and disinfection performance of B 50 NPC electro-Fenton. Heterogeneous electro-Fenton (EF) is an attractive process for refractory and hazardous pollutants degradation that usually relies on •OH produced via the in-situ decomposition of electro-generated H 2 O 2 on metal-based catalytic sites, which faces the problems of metal shedding and leaching under acidic or even neutral conditions. Designing and investigating a bifunctional metal-free catalyst is a sensible strategy for the development of heterogeneous EF process. Herein, the bifunctional metal-free boron and nitrogen co-doped porous carbon (B X NPC) catalysts were prepared. Total organic carbon removals of hazardous and refractory antibiotics (ciprofloxacin, levofloxacin, sulfamethoxazole, tetracycline, and norfloxacin) by B 50 NPC EF process were 67 ± 2% − 90 ± 2% in 3 h. This process could efficiently treat actual pharmaceutical factory wastewater that chemical oxygen demand (COD) removal was 86.8 ± 1.3% with specific energy consumption of 3.7 ± 0.2–6.7 ± 0.1 kWh (kg COD) −1 superior to previous reports (5.5–290 kWh (kg COD) −1 ). Theoretical calculations and experiments revealed that the B sites and carbon defects in B 50 NPC promoted •OH and 1 O 2 generation, respectively, synergistically enhancing antibiotics removal. The results of toxicity evaluation and E. coli deactivation demonstrated excellent detoxification and disinfection performance. The results gain deep insights into the O 2 reduction mechanism of bifunctional metal-free B X NPC and developing an energy-efficient electrochemical process for promoting the decomposition of hazardous and refractory antibiotics.

Intrinsically safe aqueous zinc ion batteries (AZIBs) are attractive for grid-level energy storage, however, its commercialization still faces the issues of dendrite growth, parasitic side reactions, and low zinc utilization of anode. Herein, we develop a stable Zn-plated Fe anode by electrodepositing zinc on iron foil. A bifunctional molecule, 3-mercapto-1-propanesulfonate (MPS), was employed to construct an MPS-derived assembled bridge interface (ABI) at the Fe Zn interface, where the thiol groups of MPS coordinate with Fe and Zn to form localized Fe S and Zn S interfacial linkages, strengthening the interfacial connection, while sulfonate groups regulate Zn 2+ distribution and nucleation. The ABI mitigates the interfacial instability arising from the large lattice mismatch between Fe and Zn and promotes homogeneous zinc deposition, thereby forming a high-performance Zn-MPS/Fe (ZMF) anode. Symmetric ZMF cells exhibit stable cycling performance, operating for 2800 h at 0.5 mA cm − 2 . ZMF//Cu half-cells demonstrate outstanding reversibility with only 44.0 mV polarization. This work presents a molecular-engineering strategy for constructing high-performance, low-cost Fe-supported Zn anodes.

Pd/NiFe LDH heterointerfaces are constructed for electrooxidation of EG to GA. • Pd/NiFe LDH/NF reaches 100 mA cm −2 at 0.58 V vs. RHE for EGOR. • Pd/NiFe LDH heterointerface enhances OH – adsorption and weakens GA adsorption. The electrooxidation of ethylene glycol (EG) to glycolic acid (GA) is limited by poor OH – adsorption on Pd-based catalysts. In this work, a Pd/NiFe LDH/NF heterostructured catalyst was constructed by depositing Pd on NiFe layered double hydroxide (LDH) supported on nickel foam (NF) for efficient ethylene glycol electrooxidation (EGOR). The Pd/NiFe LDH heterointerface regulates the electronic structure of Pd sites, thereby enhancing the adsorption and activation of EG on Pd sites. And the heterointerface facilitates OH – adsorption, which promotes the conversion of C2 oxygenated intermediates toward GA. Moreover, Pd/NiFe LDH/NF shows relatively weak adsorption toward GA, which favors GA release from active sites and suppresses its further oxidation. Through this interfacial electronic modulation, Pd/NiFe LDH/NF delivers excellent EGOR performance, reaching 100 mA cm −2 at 0.58 V vs. RHE and achieving a maximum GA Faradaic efficiency of 95.7%. This work provides an interfacial design strategy for regulating EGOR over Pd-based catalysts and improving GA selectivity. Download: Download high-res image (98KB) Download: Download full-size image

In this study, an Ag/CuV 2 O 6 composite was constructed by loading Ag NPs onto CuV 2 O 6 nanowires through a sodium borohydride reduction method. The introduction of Ag NPs significantly enhanced the photocatalytic antibacterial effect of CuV 2 O 6 . Specifically, the material exhibited the optimal photocatalytic antibacterial performance when the Ag loading was 3%. During the antibacterial process, as the illuminated time increases, the membrane structure of bacteria is gradually impaired, and intracellular contents including K + , RNA, and proteins are gradually leaked out, ultimately resulting in bacterial inactivation. EPR and free radical scavenging experiments have confirmed that reactive oxygen species (ROS), including singlet oxygen ( 1 O 2 ) and superoxide anion radicals (·O 2 - ), generated via photocatalysis, are the main factors in killing bacteria. As an excellent electron transporter, Ag effectively promotes the separation of electron-hole pairs in CuV 2 O 6 , enhances the generation efficiency of ROS, and thereby improves the photocatalytic antibacterial activity. To address the limitation of photocatalysis requiring continuous light irradiation, the long-afterglow fluorescent material ZnGa 2 O 4 :0.5%Tb 3+ was further introduced. Under intermittent light irradiation, the material stores energy upon excitation by the light source. After the light irradiation is terminated, it continues to activate the Ag/CuV 2 O 6 composite, allowing the generation of ROS even in the dark and thus achieving a delayed antibacterial effect. This study provides a new strategy to reduce the dependence of photocatalytic antibacterial technology on continuous light sources.
