As the deepest vertebrate in the ocean, the hadal snailfish (Pseudoliparis swirei), which lives at a depth of 6,000–8,000 m, is a representative case for studying adaptation to extreme environments. Despite some preliminary studies on this species in recent years, including their loss of pigmentation, visual and skeletal calcification genes, and the role of trimethylamine N-oxide in adaptation to high-hydrostatic pressure, it is still unknown how they evolved and why they are among the few vertebrate species that have successfully adapted to the deep-sea environment. Using genomic data from different trenches, we found that the hadal snailfish may have entered and fully adapted to such extreme environments only in the last few million years. Meanwhile, phylogenetic relationships show that they spread into different trenches in the Pacific Ocean within a million years. Comparative genomic analysis has also revealed that the genes associated with perception, circadian rhythms, and metabolism have been extensively modified in the hadal snailfish to adapt to its unique environment. More importantly, the tandem duplication of a gene encoding ferritin significantly increased their tolerance to reactive oxygen species, which may be one of the important factors in their adaptation to high-hydrostatic pressure.

Solar seawater evaporation is an emerging solution to combat the global water shortage problem. Bamboo is valued due to its porosity, thermal insulation, and hydrophilic properties in areas facing the problem of seawater evaporation. However, the surface of pure bamboo is not strong enough to absorb sunlight, resulting in low solar water evaporation efficiency. Hence, we used an uncomplicated surface self-assembly method to load pollution-free polydopamine on pure bamboos by hydrogen bonding. The decoration of black polydopamine enhances the absorption of sunlight throughout the device. Considering the advantages of bamboo as a substrate material and polydopamine as a photothermal conversion layer, the PDA-bamboo proves effective in solar seawater evaporation. The evaporation device can achieve an evaporation rate of 1.095 kg m–2 h–1 and evaporation efficiency of 73.64% under one solar illumination. The PDA-bamboo also finds wide application in water purification. Furthermore, PDA-bamboo is highly reusable and can maintain steady after 21 times of repeated use. The results suggested that the PDA-bamboo evaporation device can play a significant role in solving the problem of the scarcity of earth’s water.

Energy-dissipating
materials have the ability to protect fragile
items from impact-induced damage; however, currently investigated
energy-dissipating materials are generally unable to adapt to items
with different shapes because they lack shape programmability. Herein,
a highly damping polymer hydrogel with thermoresponsive shape programmability
is introduced, which was prepared through the copolymerization of
acrylic acid and adamantan-1-yl acrylate, followed by coordination
with calcium acetate. The hydrogel exhibits excellent shape memory
performance due to the Ca 2+ -assisted hydrophobic phase
separation and can be programmed into various temporary shapes. Moreover,
the hydrogel possesses a high damping capacity owing to the hydrophobic
association of the adamantyl moieties and the dynamic coordination
between Ca 2+ and the hydrogel network. By combining excellent
shape memory capability with high damping performance, the hydrogel
demonstrates great potential for applications in protecting items
with various shapes.

Flexible pressure sensors offer unique advantages for deep-sea exploration, yet balancing sensitivity, range, and environmental robustness—especially under extreme hydrostatic pressure and temperature gradients that induce signal drift—remains challenging. Here, we report a fully integrated iontronic pressure sensor for ocean exploration. Through co-design of a gradient-microstructured ionogel with a linear-elastic polyurethane spacer, the sensor achieves an unprecedented broad linear sensing range of 0–10 MPa, sensitivity of 98.4 kPa −1 , and exceptional linearity ( R 2 = 0.996). Notably, the sensor retains repeatability and signal stability under hydrostatic loading up to 55 MPa. Field deployments on a remotely operated vehicle and a manned submersible at depths of ∼1353 and ∼2359 m confirmed stable performance in the bathyal zone. An ultra-low-power embedded system (quiescent current: 4 µA) integrated with a thermal compensation algorithm enables autonomous data acquisition, suppressed temperature-induced drift, and correction accuracy exceeding 95%. This integrated iontronic platform addresses unmet needs for next-generation deep-sea monitoring and enables reliable in situ oceanographic sensing.

In this study, papain and neutral protease were used to hydrolyze the sea cucumber intestines, while the degree of hydrolysis (DH) was used as the evaluation metric. The enzymatic hydrolysis process was optimized through single-factor experiments and response surface methodology. Three types of sea cucumber intestinal peptides with different molecular weights (> 3 kDa, 1–3 kDa, and < 1 kDa) were prepared and the in vitro antioxidant activities were determined. The results showed that the optimal enzymatic hydrolysis conditions were a time of 3 h, an enzyme dosage of 4454 U/g, and a temperature of 54 °C, at which the DH reached 52.28 ± 0.54%. Peptides with the molecular weights of < 1 kDa possessed the highest scavenging abilities against DPPH radicals (IC50 = 8.97 ± 0.04 mg/mL), superoxide anion radicals (IC50 = 11.67 ± 0.21 mg/mL), and hydroxyl radicals (IC50 = 8.86 ± 0.06 mg/mL). Subsequently, using milk powder, < 1 kDa sea cucumber intestinal antioxidant peptides, xylitol, and magnesium stearate as the main raw materials, sea cucumber intestinal antioxidant peptide milk tablets were produced through processes such as mixing, granulation, drying, sizing, and tableting. The formula was optimized based on sensory evaluation scores through single-factor and orthogonal experiments. The resulting milk tablets showed a weight variation of 2.17 ± 1.87%, a hardness of 95.05 ± 3.24 N, and a total color difference (ΔE) of 8.30 ± 0.27, while exhibited a smooth and uniform surface, a fine texture, moderate sweetness, and a harmonious flavor. This study provides a theoretical foundation for the high-value utilization of sea cucumber intestinal peptides and technical support for the development of new functional foods. Graphical abstract

Electrochemical ozone (O 3 ) production (EOP) faces a critical challenge due to the competitive oxygen evolution reaction (OER), which severely limits ozone yields. Inspired by the oxygen-binding mechanism of heme, we designed a biomimetic catalyst, FePP@SnO 2 @CA, by electrodepositing iron porphyrin (FePP) onto SnO 2 @CA nanosheets, endowing it with an “oxygen-locking property” to suppress competing OER. This catalyst demonstrates exceptional EOP performance, achieving an ozone production rate of 8.9 mmol cm −2 h −1 and a Faraday efficiency (FE) of 20.46% ± 1.6%. DFT calculations confirm that Fe–O 2 interactions stabilize O 2 * intermediates, redirecting the reaction pathway from OER to ozone generation and reducing the O–O coupling energy barrier, thereby enabling thermodynamic selectivity control. In addition, when FePP@SnO 2 @CA is used as a dual-functional material for sea sand desalination, the chlorine removal efficiency can reach 52.7%. This work provides a novel bioinspired strategy for EOP catalyst design and broadens the application potential of FePP@SnO 2 @CA in sustainable technologies.

Electrocatalysis, a form of heterogeneous catalysis, is closely associated with both catalyst properties and the catalyst/electrolyte interfacial microenvironment. Herein, we rationally design and synthesize a unique PdCu nano-sea urchins (PdCu NSUs) featured with high-curvature nanotips, by which the interfacial microenvironment is expected to be tailored to the electrocatalytic reactions. PdCu NSUs exhibit excellent activity for ethanol electrooxidation, with a specific activity of 4.11 mA cm −2 and a mass activity of 2.24 mA μg Pd −1 , and a high Faraday efficiency (FE) of 96.4% toward acetic acid. COMSOL finite element simulations confirm that the unique nanotips could induce a local electric field due to the accumulation of positive charges in the nanotips, resulting in enrichment of OH - at the catalyst surface to promote the formation of Pd−OH ads , a species required by ethanol dehydrogenation. Furthermore, DFT calculations and in-situ electrochemical Fourier transform infrared spectroscopy discover that the d-band center of Pd significantly downshifts in PdCu alloy, which facilitates the desorption of the produced acetic acid. This work provides a new electrocatalytic material with high-curvature nanotips, and also clarifies how the material morphology, by inducing local electric fields, affects the interfacial microenvironment and thus the catalytic activity and selectivity.

Graphical This paper presents a urchin-like graphitized carbon-coated SnO₂ (GC-SnO₂) composite. Its spine-like carbon structure with branched networks alleviates stress concentration in SnO₂ anodes during cycling, enabling efficient ion transport. This design enhances high-rate performance and structural stability of lithium-ion batteries. Tin dioxide (SnO₂) has emerged as a promising anode for lithium-ion batteries (LIBs) due to its high theoretical capacity and natural abundance. However, it suffers from severe volume expansion during lithiation/delithiation processes and limited rate capability. To address these challenges, this work rationally designed an urchin-like-graphitized carbon (GC)-SnO₂ microsphere composite (denoted for GC-SnO 2 ) through hydrothermal synthesis followed by controlled annealing. The hierarchical architecture consists of hollow SnO 2 nanospheres encapsulated within branched graphitized carbon protrusions, forming a hierarchically porous network. This structural design enables three key advantages: (1) accelerated Li + diffusion through interconnected channels, (2) stress buffering via spiny carbon branches to mitigate SnO 2 pulverization, and (3) enhanced conductivity through conformal GC coating. Benefiting from these synergistic features, the GC-SnO 2 anode exhibits outstanding cyclability, maintaining 765 mA h g −1 after 100 cycles at 0.2 A g −1 . Notably, it achieves 538 mA h g −1 at 2 A g −1 over 1000 cycles, surpassing bare SnO 2 (89 mA h g −1 ) and exceeding the performance of most reported SnO 2 -based anodes. This work provides an effective strategy for designing stress-tolerant oxide/carbon composites toward high-energy-density LIBs.

The compatibility of low-density polyethylene (LDPE) and polyamide 6 (PA6) during melt-blending spinning plays a crucial role in ensuring good spinnability, while the drawing and fiber-splitting processes are key to forming ultrafine fibers. This study systematically investigates the Flory–Huggins interaction parameters between LDPE and PA6, as well as the fiber-splitting and drawing behaviors of unfigured sea–island composite fibers, with a focus on compatibility and fabrication techniques. The results reveal that the Flory–Huggins interaction parameters for LDPE and PA6 at different blend ratios are 0.0517 ± 0.0014, significantly exceeding the critical interaction threshold of 0.0091, indicating complete incompatibility between the two polymers. Through an in-depth analysis of the drawing process, it was found that after the drawing ratio of 4, the fiber fineness reached 3.7 dtex, with a fiber orientation of 78%, a breaking strength of 5.56 cN/dtex, and a breaking elongation of 41%. During the fiber-splitting process of LDPE/PA6 sea–island composite fibers, the optimal conditions were determined to be a splitting temperature of 90 °C, a splitting time of 60 min, and a degradation rate of 43%. Under these conditions, the composite fiber diameter significantly decreased from 27.04 μm to 0.85 μm. These findings provide valuable insights into optimizing the manufacturing process and enhancing the performance of LDPE/PA6 composite fibers.

Peroxymonosulfate (PMS) activation by cobalt manganese spinel (Co-Mn) is always unsatisfactory due to the interference of co-existing anions in water. In this study, we used a sulfate-modification strategy to prepare a sea urchin-like Co-Mn catalyst (CoMn 2 O 4 -S) with abundant oxygen vacancies for counteracting the interference of anions in pollutant degradation. Compared with the conventional Co-Mn catalyst (CoMn 2 O 4 ), CoMn 2 O 4 -S exhibited higher resistance to poisoning of NO 3 − , Cl − , and SO 4 2− in PMS activation involved phenol degradation. Additionally, H 2 PO 4 − could even enhance phenol degradation by 150.2% for CoMn 2 O 4 -S/PMS system, in contrast to its induced 18.5% inhibition to CoMn 2 O 4 /PMS system. It was demonstrated that vacancies and sea urchin structure alleviated catalyst agglomeration for preserving catalytic sites and promoted catalyst surface modulation for radical diffusion, contributing to the enhanced stability in saline water. This work provides a facile strategy for overcoming the negative effects of co-existing anions on heterogeneous PMS-activation based water treatment.

Surface-enhanced Raman scattering (SERS) has gained significant attention in various fields, including biomedical diagnostics, environmental monitoring, and food safety. This technique offers many advantages such as label-free detection and the ability to detect analytes at low concentrations. In this study, we present a variety of tungsten oxide (W 18 O 49 ) microstructures as solid SERS substrates using various solvents realized by a simple hydrothermal approach. Among them, the well-defined sea urchin-like W 18 O 49 microstructures support greater light scattering and confinement to enhance the SERS signal when compared to other W 18 O 49 structures. The surface of well-defined sea urchin-like W 18 O 49 microstructures was then modified with uniformly distributed silver nanoparticles (Ag NPs). The combination of the unique morphology of the Ag and sea urchin-like W 18 O 49 microstructures (W 18 O 49 @Ag) led to improved detection capabilities for analytes such as rhodamine 6 G (R6G) and thiram molecules. The SERS enhancement factor (EF) of sea urchin-like W 18 O 49 @Ag microstructures was estimated to be as high as 1.53×10 6 with the lowest detectable concentrations of 1 nM and 1 μM for R6G and thiram, respectively. Thus, the well-defined sea urchin-like W 18 O 49 @Ag microstructures are excellent choice to replace the pure noble metal SERS substrates in the fields of rapid detection and trace analysis due to their high sensitivity, repeatability, and long-term stability.
