Solar-driven brine desalination faces two critical challenges: the high energy barrier of water vaporization and severe salt accumulation. To address these, we designed a lotus-seed-pod inspired hydrogel evaporator with a hierarchical structure and heterogeneous interface. By precisely patterning hydrophobic domains on a hydrophilic network on heterogeneous interface, the interface actively reconfigures hydrogen-bonding, enriching weakly bonded intermediate water and reducing the vaporization enthalpy by 26.6%. This thermodynamic advantage, coupled with synergistic thermal and solutal Marangoni convection, yields robust, self-regulating salt resistance. Consequently, the evaporator achieves a high evaporation rate of 2.82 kg·m −2 ·h −1 at 92.2% efficiency in 20 wt% brine, maintaining zero salt crystallization over 240 h of continuous operation. Numerical simulations further confirm that precise regulation of the spatial distribution, strength, and connectivity of hydrogen bonds simultaneously optimizes water transportation. This work reveals that bio-inspired interfacial design with patterned wettability and confinement domains lowers the phase-change energy barrier, enabling efficient, salt-resistant solar evaporation for sustainable water technologies.

Owing to superior comprehensive performance, polyimide film (PI) has been extensively used as flexible substrate to support and fix electronic components. However, the current PI film has inferior thermal conductivity, especially in the vertical direction, causing failure of electronic devices in overheating conditions. Herein, an electrically insulating pea-pod-like filler with high thermal conductivity in both horizontal and vertical directions was prepared by encapsulating interconnected carbon microsphere (CM) with graphene-like carbon nitride (g-C3N4). The resultant thermal conductivity of PI film in horizontal and vertical directions has been improved by 11 (1.98 W m–1 K–1) and 2.4 (0.43 W m–1 K–1) times at 30 wt % CM@g-C3N4 loading, respectively. Furthermore, benefiting from satisfactory light absorption of CM@g-C3N4, the PI/CM@g-C3N4 film displays rapid heating capability under illumination. Meanwhile, the PI/CM@g-C3N4 film keeps intrinsic electrical insulation, thermal and dimensional stabilities. This work provides an effective method to solve the bottleneck of the current PI film in inadequate thermal conductivity.

The peony pod is a component of the cash crop oil peony (Paeonia suffruticosa Andr.), it accounts for more than half of the quality of the peony seed. However, indiscriminate disposal leads to resource waste. In addition, the pollution caused by the overuse of antibiotics and the evolution of resistance have been a conundrum. There is an urgent need to find a pollutant removal method that conforms to the current concept of sustainable development. In this study, the biomass porous carbon (PC N, Fe -0.5) was prepared and modified by one-step synthesis method using the by-product peony pod as carbon precursor, urea as nitrogen source, and steel slag as magnetic material. The utilization of biomass waste solved resources waste caused by the unreasonable disposal of agricultural solid waste. The doped materials were cheap and easy to obtain, and they improved the structure and function of porous carbon. The maximum adsorption capacity of PC N,Fe -0.5 reached 726.4 mg·g −1 with 100 mg·L −1 of tetracycline (TC). The adsorption mechanism was summarized as pore filling, van der Waals force, π-π EDA, surface complexation, hydrogen bonding and chemisorption . A low-budget tetracycline (TC) removal method was explored through the investigation on the adsorption performance and recovery capability of PC N,Fe -0.5, which was also conducive to realizing the recycling of biomass waste and industrial waste.

Rapid industrialization poses a serious threat to the balance of ecosystems and environmental sustainability, and the application of membrane technology is an effective way to alleviate this situation. Two-dimensional (2D) MXene nanosheets are superior materials for constructing high-performance separation membranes, but their biggest drawback is that they are prone to agglomeration. After alkalizing them, the obtained alkaline MXene (TCOH) nanosheets have hydroxyl-rich surfaces, stabilized structure and great affinity for CO 2 . Based on this, a self-supported TA-ZIF-8/TCOH@Pebax mixed matrix membranes (MMMs) with block polymer Pebax-1657 as matrix and TA-ZIF-8/TCOH as composite filler were prepared in this work. ZIF-8 was modified with tannic acid (TA) to enrich the surface with hydroxyl groups, yielding TA-ZIF-8 that is both pro-CO 2 and well interfacially compatible. The using of TA-ZIF-8 not only improves the selectivity of the separation membrane, but also its mutually repulsive electrostatic force with TCOH can expand the layer spacing of TCOH nanosheets as much as possible, which leads to a rich gas transportation channel of the membrane. Experiments have shown that the prepared TA-ZIF-8/TCOH@Pebax MMM had outstanding separation performance beyond the 2019 Robinson upper bound when the content of TA-ZIF-8 was appropriate. Also, the TA-ZIF-8/TCOH@Pebax MMM showed superior thermal stability, durability and mechanical properties. In summary, the strategy of combining nanoparticles and nanosheets as composite fillers in this study provides an effective way to regulate the low permeance of MMMs. In the meantime, the application of TCOH provides a novel idea for further research on gas separation membranes.

This study employed ultrasound-assisted extraction to obtain polysaccharides from Albizia julibrissin Durazz. leaf and pod agricultural by-products, with subsequent process optimization. A comparative analysis was then conducted on the physicochemical properties and anticomplementary activity of the isolated polysaccharides derived from two parts. The investigation identified different extraction conditions for leaf and pod, leaf demonstrated maximum polysaccharide yield (1.07 ± 0.20%) at 70°C, 40 mL/g, 50 min and 249 W, contrasting with pod which achieved 8.32 ± 0.27% yield at 70°C, 28 mL/g, 40 min and 201 W. Besides, physicochemical characterization demonstrated distinct molecular weights between leaf (AJLP) and pod (AJPP) polysaccharides (62.55–232.30 kDa) despite shared functional groups. Both polysaccharides contained mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, and arabinose in varying ratios, while displaying divergent microstructures and excellent thermal stability. In vitro, leaf (AJLP) and pod (AJPP) polysaccharides exhibited potent anticomplementary activity in alternative and classical pathways, respectively. This study established a foundation for developing and utilizing polysaccharide resources from A. julibrissin agro-byproducts, while providing a theoretical basis for their application in complement system overactivation.

It has been broadly studied to ensure the protection of magnesium alloy by superhydrophobic surface. In this work, the layered TiO 2 was prepared in response to the AZ31 Mg alloy by hydrothermal method and loaded wrinkled silicon dioxide (KCC-1) on the layer by electrostatic self-assembly to build a pod-like structure. After modification by stearic acid, the surface shows superhydrophobicity. The morphology, structure and composition of the surface were characterized by scanning electron microscope (SEM), the X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), respectively. The anticorrosive effect of the superhydrophobic surface was investigated by detecting the electrochemical impedance spectroscopy and polarization curves in 3.5 wt% NaCl solution for a week. Superhydrophobic surfaces also exhibited chemical stability, physical stability and ultraviolet light tolerance. In addition, the TiO 2 containing in the film had a certain photocatalytic performance on decomposition of organic contaminants. Combining the self-cleaning property, the surface showed excellent adaptability to the outdoor environment.

In this report, novel pod-like nitrogen-doped carbon fibers encapsulated with cobalt/cobalt oxide nanoparticles (Co/CoO x -N-C) were prepared by a facile method. Co/CoO x -N-C can be readily obtained from the carbonization of electrospun ZIF-67@PAN fiber. Both effects of ZIF-67 crystal size and pyrolysis temperature on the ORR were investigated. The optimal Co/CoO x -N-C-l, which has an average ZIF-67 size of 370 nm and a carbonization temperature of 800 °C, presents features of 1D hierarchical porosity pod-like structure, dispersion of nanoparticles, high content of N dopant, and high degree of graphitization, resulting in an excellent ORR performance. Co/CoO x -N-C-l presents an onset potential of −0.07 V (vs Ag/AgCl), a half-wave potential of −0.144 V, and a diffusion limited current density at 0.6 V of 4.9 mA/cm 2 . The relative current of Co/CoO x -N-C-l (90.1%) is much higher than that of the 20 wt% Pt/C (79.8%) after a 36,000 s of continuous operation. In addition, Co/CoO x -N-C-l was further applied as a cathode catalyst of the Zn-air battery. It exhibited an outstanding discharge specific capacity (610 mAh/g) and a comparable discharge voltage to that of 20 wt% Pt/C and RuO 2 . This study may provide a novel strategy to generate pod-like structured nanocomposites for energy devices.

High thermal conductivity polymer materials are highly desirable for thermal management applications in electrical encapsulation and energy fields. The construction of three-dimensional thermal conductivity structure has become an attractive method to improve the thermal conductivity of polymers. However, traditional methods for constructing 3D structures use prefabricated thermal conductivity models. Herein, we take epoxy resin as matrix, through the cooperation of sheet BN and spherical Al 2 O 3 to in situ construct a “pea-pod-like” 3D thermal network, to prepare high thermal conductivity Al 2 O 3 -BN-Epoxy (ABE) composites. Compared with pure epoxy resin, the thermal conductivity of the ABE composites and the random Al 2 O 3 -BN-Epoxy (R-ABE) composite is increased by 257% and 63%, respectively. And it still has a high thermal conductivity at low temperatures (696% enhancement at 60 K) for ABE 60% composite. This method of in situ construction of 3D thermal conductivity networks is of great significance in the development and application of thermal management materials.

An efficient mimic peroxidase platform of Fe-CDs/GOx based on the hybrid cascade system to produce in-situ H 2 O 2 for the visualized detection of glucose has been also developed in our group. Herein, the [Fe-CDs + H 2 O 2 + TMB] system was further performed to detect the biothiols (GSH, Cys, and Hcy) as representatives of the –SH group. The result exhibits that the higher concentration of biothiols can cause the absorbance signal at 652 nm to decrease, and the deep-blue color of oxTMB turns green until it is faded in 20 min by the naked eye. The colorimetric method showed the LOD are 0.54, 0.29, and 1.41 μM for GSH, Cys, and Hcy respectively, without interference in the presence of other amino acids. The smartphone-based and paper-based determination display good respect for biothiols in human serum or GSH in red wine. These simple and convenient strategies provide potential applications in the fields of clinical diagnosis and foods.

Noble metal nanoparticles show good application prospects in biosensors and anti-tumor drug research. Herein, the near-spherical silver‑palladium bimetallic nanoparticles supported by elm pod polysaccharide (EPP-AgPd 1.5 NPs) were prepared by using the elm pod polysaccharide (EPP). EPP acts as a stabilizer and reducing agent due to its water solubility and weak reducing ability. The particle size of EPP-AgPd 1.5 NPs was 33.6 ± 5.5 nm. In addition, EPP-AgPd 1.5 NPs had peroxidase-like activity to catalyze 3,3′,5,5′-tetramethylbenzidine (TMB) to oxidized TMB by catalyzing H 2 O 2 to OH. Based on the peroxidase-like activity of EPP-AgPd 1.5 NPs, a method for detecting glutathione was established, and the detection limit and linear range of glutathione concentration were 0.279 μM and 0–400 μM, respectively. More importantly, the photothermal conversion efficiency of EPP-AgPd 1.5 NPs reached 39.7 %, and their inhibition rate in HeLa cells reached 69.9 %. Silver‑palladium bimetallic nanoparticles stabilized by EPP had good performance in glutathione detection and anti-tumor drugs.

Exploring novel-type nanozymes with programmatically manipulated enzyme-mimicking activity for targets’ accurate identification and multimodal biosensing represents one of the most fascinating yet challenging research frontiers. Herein, taking DNAs as programmable biotemplates, we prepared bimetallic PtAg nanocluster-zyme via simple in situ reduction. Among them, the A20-templated PtAg nanozyme exhibited superior peroxidase-like (POD-like) activity, as confirmed by optical analyses, steady-state kinetics, and electron paramagnetic resonance spectroscopy, with •O2– and •OH identified as the primary reactive oxygen species. Taking Pt-AMP with the Pt–N4 coordination structure as representative, pluralistic DFT calculations were performed. Corresponding results manifested the superior affinity of nanozyme for H2O2 and TMB, the elongated O–O bond length of H2O2 and facilitated electron-transfer ability at the catalytic core. Subsequently, by harnessing the efficient catalytic oxidation of TMB and AR, we fabricated a colorimetric-photothermal-fluorescent trimodal sensing platform for assessing total antioxidant capacity and alkaline phosphatase activity. Superior to previous single/dual-modal biosensors, this work demonstrated significant advantages in sensitivity, reliability, and accuracy, and showed acceptable adaptability in diversified real matrices (human serum, tablets, and beverages). Furthermore, we fabricated target-responsive cascade logic circuits by virtue of the proper incorporation of trimodal signals and Boolean logic, and achieved the smart recognition of targets. This work not only provided a mild, simple, and efficient biotemplated approach for the programmable tuning of noble-metal nanozymes’ catalytic activity but also enlightened novel pathways for the operation of logic-empowered intelligent biosensors.

The novel binary metal oxide cerium molybdate (Ce 2 Mo 3 O 13 ) as a promising strategy can be combined with MWCNTs for the development of ultrasensitive sensors. Herein, a pod-like Ce 2 Mo 3 O 13 was prepared, characterized, and used to construct a molecularly imprinted sensor (MIPs) for detection of ponceau 4 R as low as to nanomolar concentration. The results demonstrate that the electrochemical response at the specific hybridized electrode of MIPs/Ce 2 Mo 3 O 13 -MWCNTs/GCE is stronger than non-molecularly imprinted ones (NIPs). It indicates a synergistic effect resulting from the hybridized Ce 2 Mo 3 O 13 -MWCNTs combination and modification to the electrode. Under optimal conditions, the calibration curve is in the range of 10 nmol L −1 to 1 μmol L −1 , with a limit of detection of 7 nmol L −1 for ponceau 4 R determination. The excellent sensitivity, reproducibility, and selectivity of the new sensor provide an accurate and facile avenue for ultrasensitive ponceau 4 R detection in different samples.
