Pseudocapacitors, which store charge through fast reversible redox reactions occuring at the surface of the electrode, could offer higher specific capacitance than electrochemical double-layer capacitors (EDLCs). However, the prime pseudocapacitive phase, transition metal oxides usually have poor electronic conductivity, limiting their practical application. Here, we fabricated highly conductive HxMoO3−y nanobelts as electrode materials for pseudocapacitors. This electrode has demonstrated great electrochemical activity in various aqueous cation solutions with the highest volumetric capacitance of over 350 F cm−3. Significantly, this electrode has high specific capacitance as well as excellent cycling stability in sea water. Moreover, this hybrid composite also exhibits remarkable ion electrosorptive capacity (4 mg g−1) as a desalination electrode.

This study employed the flavour variations in sea cucumber intestines through sensory and instrumental analyses following different boiling and steaming treatments with water (WB, WS) or green tea water (GB, GS). A dictionary comprising eight descriptors was employed for sensory evaluation. Attributes such as tea flavour, sweet, fishy, briny, fatty, fresh, dark appearance and moist appearance were identified using Free Choice Profiling and Check-all-that-apply methods. A total of 57 volatile compounds were identified by gas chromatography-ion mobility spectrometry. According to the taste activity value (TAV), malic acid and succinic acid were identified as important flavour substances. Glutamic acid (Glu) exhibited a TAV > 1 only in the CON, WS20 and GS20 groups. Steaming exerted a less pronounced impact on flavour compared to boiling. Chord diagram analysis revealed superior efficacy for the GS20 treatment, affirming its utility in flavour assessment of sea cucumber intestines.

Memory impairment is becoming a potential health issue with the delicacy of diet and social stress. Sea cucumber peptides (SCP) prevent memory impairment, as previously reported. In this study, further research was performed using hippocampal lysine-acetylome to explore molecular regulation mechanisms. C57BL/6 mice were treated with scopolamine via intraperitoneal injection to simulate memory impairment. To determine the influence of SCP on the total acetylated-protein level of the hippocampus, acetylated-proteomics was performed. SCP increased the acetylation level of histone (H3 and H4). Meanwhile, for non-histones, the differentially acetylated proteins were involved in multiple memory-related pathways, as shown by KEGG enrichment analysis. Additionally, long-term potentiation was confirmed by western blotting. Finally, a combined analysis of proteome and lysine acetylome revealed that SCP contributed to synaptic vesicle cycle regulation and dopamine metabolism. Consequently, our findings revealed that SCP was potentially neuroprotective by regulating post-transcriptional hippocampal protein acetylation.

Root-knot nematode diseases cause severe yield and economic losses each year in global agricultural production.Virgibacillus dokdonensisMCCC 1A00493, a deep-sea bacterium, shows a significant nematicidal activity againstMeloidogyne incognitain vitro. However, information about the active substances ofV. dokdonensisMCCC 1A00493 is limited. In this study, volatile organic compounds (VOCs) fromV. dokdonensisMCCC 1A00493 were isolated and analyzed through solid-phase microextraction and gas chromatography–mass spectrometry. Four VOCs, namely, acetaldehyde, dimethyl disulfide, ethylbenzene, and 2-butanone, were identified, and their nematicidal activities were evaluated. The four VOCs had a variety of active modes onM. incognitajuveniles. Acetaldehyde had direct contact killing, fumigation, and attraction activities; dimethyl disulfide had direct contact killing and attraction activities; ethylbenzene had an attraction activity; and 2-butanone had a repellent activity. Only acetaldehyde had a fumigant activity to inhibit egg hatching. Combining this fumigant activity against eggs and juveniles could be an effective strategy to control the different developmental stages ofM. incognita. The combination of direct contact and attraction activities could also establish trapping and killing strategies against root-knot nematodes. Considering all nematicidal modes or strategies, we could useV. dokdonensisMCCC 1A00493 to set up an integrated strategy to control root-knot nematodes.Keywords:virgibacillus dokdonensis;Meloidogyne incognita;volatile organic compound;fumigant;attraction;repellent;integrated strategy

Non-metallic Surface-Enhanced Raman Scattering (SERS) substrate materials with unique structures are considered as promising candidates for detection of dyes in the environment. In this work, a sea urchin-like K 2 Ti 8 O 17 (KTO) nanomaterial was prepared by a facile and efficient hydrothermal method . The enhancement factors of the sea urchin-like KTO for crystal violet and methylene blue are 3.8 × 10 5 and 2.45 × 10 5 respectively, and the minimum detection limits of both can reach 10 −8 M, which means the sea urchin-like KTO a promising non-metallic SERS substrate for detecting dyes in the environment. The excellent SERS performance of the sea urchin KTO was attributed to the excellent charge transfer and probe adsorption capability of KTO by energy band and zeta potential analysis. Finally, the excellent application potential of the sea urchin KTO was verified by simulating a practical use scenario.

Rapid detection of marine fish freshness is of great importance, as aquatic products are susceptible to spoilage during storage. In this work, for the first time, the laser induced breakdown spectroscopy (LIBS) coupled with multivariable analysis was used for the rapid identification of the freshness of sea bass ( Lateolabrax japonicus ) without using of organic solvents. Results suggested that the principal component analysis (PCA) could accurately differentiate the sea bass samples stored for different days, and the three freshness grades (first-grade, second-grade, and spoilage) of sea bass were separately clustered together. The overall classification accuracy of partial least squares-discriminant analysis (PLS-DA) reached 91.50% ± 1.49% and 97.33% ± 1.90% for differentiating sea bass samples stored for different days, and authenticating different freshness grades, respectively. As storage period increased, the degradation of high-molecular-weight proteins and micromorphology changes were observed in fish muscles using SDS-PAGE and SEM, respectively. In addition, the laser energy absorbed by sea bass increased with the longer storage periods, as shown by the plasma temperature and plasma electron density. The present study demonstrated the capability of LIBS combined with chemometrics for the rapid and eco-friendly identification of marine fish freshness in the food supply chain.

In this work, a mild chemical precipitation method and simple hydrothermal treatment of the nickel hexamyanocobaltate precursor strategy are developed to prepare a sea urchin-like CoNi2S4 compound with remarkable specific capacity and excellent cycling stability. The prepared CoNi2S4 has an outstanding specific capacity of 149.1 mA h g−1 at 1 A g−1 and an initial capacity of 83.1% after 3000 cycles at 10 A g−1. Moreover, the porous carbon nanospheres (PCNs) with exhibit cycling stability (94.7% of initial specific capacity after 10 000 cycles at 10 A g−1) are selected as negative electrode to match CoNi2S4 positive electrode for assembly of CoNi2S4//PCNs asymmetric supercapacitor (ASC). Satisfactorily, the as-assembled CoNi2S4//PCNs ASC exhibits an impressive energy density of 41.6 Wh kg−1 at 797 W kg−1, as well as the suitable capacity retention of 82.8% after 10 000 cycles. The superior properties of the device demonstrated that the as-prepared material is potential energy storage material.

Sea buckthorn leaf tea, an emerging potential functional beverage product, has not yet had appropriate product standards and corresponding quality evaluation methods, and its poor taste directly affects the acceptance of the population, thus limiting its market consumption potential. In this study, two major packaging forms of sea buckthorn leaf tea available in the Chinese market were selected. The contents of total phenolics, total flavonoids, and 10 phenolic compounds, as well as the in vitro antioxidant capacity and sensory characteristics of sea buckthorn leaf tea were analyzed. Results showed that the quality of sea buckthorn leaf tea in the Chinese market varied widely. The total phenolic content, total flavonoid content, antioxidant activity, and consumer acceptance of bagged sea buckthorn leaf tea were higher than those of bulk sea buckthorn leaf tea. Multifactorial statistical analysis showed that the taste astringency of sea buckthorn leaf tea was closely related to ellagic acid and isorhamnetin-3-O-neohesperidin. Furthermore, isorhamnetin-3-O-neohesperidin had a greater effect on the antioxidant activity of sea buckthorn leaf tea. Therefore, ellagic acid and isorhamnetin-3-O-neohesperidin can be used as potential quality markers for sea buckthorn leaf tea. This work provides a reference for taste improvement and quality control of sea buckthorn leaf tea.

Graphene is a two-dimensional sheet of regular hexagonal honeycomb lattice formed by sp2hybrid orbital bonding, with only one layer thickness of a single atom, which is known as the “super king” of the 21st century. Previous studies have shown that cerium oxide-graphene oxide (CeO2-GO(4:1)) nanocomposites eliminated the agglomeration of graphene to some extent and the CeO2-GO(4:1) epoxy coating could be prepared with good anti-corrosion performance. In this paper, CeO2-GO(4:1) nanocomposites were prepared by the hydrothermal synthesis method, and the three-electrode method was used for electrochemical tests. The state evolution of CeO2-GO(4:1)/EP coating and the synergy between CeO2-GO(4:1)/EP and corrosion inhibitor in simulated seawater solution with different concentrations (20%, 40%, 60%) were analyzed and illustrated by Optical Microscope (OM) characterization, Open Circuit Potential (OCP), Electrochemical alternating current Impedance Spectroscopy (EIS), Mott–Schottky curve and Tafel curve. The results indicated that CeO2-GO(4:1) nanocomposites showed good corrosion resistance in a marine environment. This research lays a solid theoretical foundation for the application of cerium oxide-modified graphene oxide anticorrosive coating in marine engineering.Keywords:CeO2-GO;corrosion inhibitor;simulated seawater;corrosion area

The key challenge in the practical application of electrochromic energy storage devices (EESDs) is the fabrication of high-performance electrode materials. Herein, we deposited K7[La(H2O)x(α2-P2W17O61)] (P2W17La) onto TiO2nanowires (NW) to construct an NW–P2W17La nanocomposite using a layer-by-layer self-assembly method. In contrast to the pure P2W17La films, the nanocomposite exhibits enhanced electrochromic and electrochemical performance owing to the 3D sea-cucumber-like microstructure. An EESD using the NW–P2W17La film as the cathode exhibited outstanding electrochromic and energy storage properties, with high optical modulation (48.6% at 605 nm), high switching speeds (tcoloring= 15 s, tbleaching= 4 s), and high area capacitance (5.72 mF cm−2at 0.15 mA cm−2). The device can reversibly switch between transparent and dark blue during the charge/discharge process, indicating that electrochromic contrast can be used as a quantitative indicator of the energy storage status.Keywords:electrochromism;energy storage;polyoxometalate;nanostructures;EESD

This study focused on preparing sea urchin palladium-copper nanospines (PdCuAu NAs) using a one-step reduction method. PdCuAu NAs is a highly branched nanomaterial composed of nanospines, and its unique structure and trimetallic composition give it excellent Fenton catalytic activity and photothermal properties. The characterization of PdCuAu NAs was carried out using SEM, XPS , and UV-Vis techniques. Under near-infrared light, PdCuAu NAs were quickly heated to 50 ℃. Compared to traditional photocatalysts , PdCuAu NAs showed better Fenton catalytic activity in the degradation of organic dyes such as MB. Furthermore, it exhibited good photothermal stability and reusability after multiple thermal cycles and repeated use. Thus, the results showed that PdCuAu NAs had a good degradation effect on organic wastewater.
