The prediction of gas concentration plays a key role in human life and health, among which CO is a common toxic gas in industry. In order to protect people's health, the prediction of CO concentration has a worthwhile attention. Electronic nose (E-nose) has performed well in gas concentration prediction in recent years. Among them, the gas concentration prediction performance of E-nose mainly depends on the goodness of the prediction model. Deep learning algorithms can utilize their multilayer networks to extract features from raw data, however, the current application of deep learning algorithms for gas concentration prediction of E-nose is still insufficient, and the prediction results using traditional neural networks often fail to be very fine. Based on this, this study proposes a mish-sample convolution and interaction network based on a multi-head attention mechanism(MHA-MSCINet) for multivariate time series prediction. Our model develops a new module and combines the improved SCINet with the multi-head attention mechanism. Meanwhile, in order to make our model interpretable, we used the SHAP value analysis method. Finally, experiments verify that the model outperforms models such as LSTM, TCN, transformer and SCINet.

Various groups of organic chemicals are commonly utilized in medicines for both veterinary and human medicine. Non-steroidal anti-inflammatory drugs (NSAIDs), particularly nimesulide (NMS), are known for their anti-inflammatory, antipyretic, and antirheumatic effects. Great concerns about NMS toxicity have prompted the creation of effective ternary metal oxide-based nanocomposite sensors.
Methods
Using a simple solution technique, we synthesized Zn2GeO4 nanoparticles, an n-type semiconductor. Zn2GeO4 nanoparticles were deposited on graphitic carbon nitride (GCN) nanosheets to improve electrocatalytic activity, conductivity, and stability. The synthesized Zn2GeO4/GCN nanocomposite was characterized by XRD, FT-IR, XPS, and FE-SEM before being formed on a screen-printed carbon electrode (SPCE) for NMS detection.
Significant Findings
Electrochemical tests using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) demonstrated a broad linear range (0.049–94.90 μM), a nanomolar detection limit (2.7 nM), and good sensitivity (5.3 µA µM-1 cm-2). In addition, the nanocomposite demonstrated higher selectivity in interference tests, as well as excellent repeatability, stability, and recovery in real-time analysis with human blood.

Background
Carbonates have been recognized as effective materials for inhibiting gas and dust explosions, while phase change hydrates have been proposed to have potential applications in the field of explosion inhibition.
Method
Using a 20 L spherical explosion test system, the inhibition effects of sodium bicarbonate (NaHCO3) and trisodium phosphate dodecahydrate (Na3PO4·12H2O, TPD) on the benzoyl peroxide dust explosion were evaluated, and the commonality and uniqueness of their inhibition mechanisms were revealed through thermodynamic analysis and numerical calculations of chemical reaction kinetics.
Significant results
The Pmax and (dP/dt)max of benzoyl peroxide explosion significantly decreased after adding NaHCO3 or TPD, but there are significant differences in the inhibition law. The commonality of inhibition mechanisms is reflected in physical inhibition effects (heat absorption and heat transfer obstruction) and chemical inhibition effects (consuming key free radicals). The uniqueness of the inhibition mechanism depends on the thermal decomposition process behavior of the inhibitors. The TPD with high endothermic enthalpy of phase transition heat absorption effectively reduce the accumulation of heat in the explosion reaction system, and macroscopically exhibit better explosion inhibition effect than NaHCO3. This work provide a reference for the application of hydrated salts in the prevention and control of organic dust explosion disasters.

Background
Corrosion occurs wherever metal and its alloys exist. Protection of metals with corrosion inhibitor is a popular topic. Considering environmental concerns and human health, it is more favorable to use green corrosion inhibitors than traditional corrosion inhibitors. Methanol extract of Arum dioscoridis (AD) becomes a potential green corrosion inhibitor and it can be used in industrial areas.
Methods
Corrosion efficiency, corrosion behavior and corrosion mechanism of Arum dioscoridis leaf extract on mild steel (MS) are illuminated in 1 M HCl by Tafel curves, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), zero charge potential, structural and surface morphological analysis and density functional theory (DFT).
Significant findings
The extract function as mixed-type corrosion inhibitor with predominantly cathodic action. Inhibition efficiency was reached the value of 97 %. Polarization resistance is measured as 761 Ω cm2 at 1000 ppm of AD. The high inhibition efficiency was attributed to phytochemicals in the AD extract. A high activation energy (70.34 kJ/mol) for inhibited solution than that of in blank solution (49.66 kJ/mol). Both physisorption and chemisorption are responsible for formation of a protective layer on MS surface to inhibit the electrochemical reactions. Optimized molecular structures in phytochemicals confirmed the inhibitive properties via DFT.

Background
Effective removal of oils and aromatic dyes from water is of critical, global importance for environmental and water remediation. Developing multifunctional membrane materials capable of both oil-water separation and in-situ catalytic degradation offers a promising, efficient, and environmentally friendly solution to this challenge.
Methods
In this study, Ag@SiO2 nanoparticles with a high specific surface area and catalytic activity were successfully synthesized. These nanoparticles were loaded onto electrospun PVDF nanofiber membranes using physical deposition. To enhance the number of active sites on Ag@SiO2, groove substructures were introduced into the PVDF nanofiber membranes during electrospinning. This modification resulted in nanofiber membranes exhibiting superhydrophilicity and underwater superoleophobicity.
Significant findings
The resulting PVDF nanofiber membranes demonstrated high water flux (1151.99 L/m2/h) and excellent oil-water separation performance (>99 %) under self-weight. Additionally, in the presence of NaBH4, the organic dye methylene blue (MB) underwent complete catalytic degradation within 4 min, with a first-order degradation rate constant of 0.567 min-1. After ten cycles, the nanofiber membranes retained over 90 % of their catalytic efficiency, indicating long-term operational stability. These nanofiber membranes offer a novel strategy for efficient oil-water separation and water purification.

Background
The solar-driven photocatalytic seawater splitting process for simultaneous hydrogen and oxygen gas has garnered significant attention as a promising technique for generating eco-friendly chemical fuels. This approach is particularly attractive because of its low cost, and the ability to utilize abundant sunlight and seawater resources.
Methods
The Rh@Cr2O3/SrTiO3:Al (RCSTOA) heterojunction photocatalyst, synthesized via flux technique and photodeposition treatment, possessed distinctive physicochemical properties and exhibited high photocatalytic seawater-splitting performance.
Significant findings
The findings emphasized that the thin layers of Rh@Cr2O3 structure (5–20 nm) firmly intimate with a SrTiO3:Al (STOA) photocatalyst significantly enhanced the seawater-splitting process without requiring any sacrificial agents. Hydrogen and oxygen evolution rates (HER and OER) in natural seawater splitting increased significantly, achieving 263 and 130 µmol.g−1.h−1, respectively maintaining photostability after five consecutive cycles under simulated sunlight illumination. Notably, under the synergy of I−-anion solution, the HER improved to 332 µmol.g−1.h−1 without any OER, highlighting potential for H₂/O₂ separation. These findings are expected to advance seawater splitting technology and contribute to potential H2/O2 separation techniques in this field.

Devices fabricated on flexible substrates find diverse applications. The advancement of materials and manufacturing methods is critical for improving flexible devices.
Method
This study compares ultrafast Ar and O2 microwave plasma (MP) treatments in terms of their high energy efficiency and high ionization rate to process solvothermally grown NiCo-metalorganic frameworks (NiCo-MOFs) on flexible carbon paper (CP) substrates.
Significant Findings
Ar MP treatment reduces the oxidation states to reveal metallic states, whereas O2 MP treatment enhances the oxidation effect with no apparent metallic reduction. Samples treated with Ar MP become less hydrophilic whereas those treated with O2 MP retain the hydrophilicity of pristine NiCo-MOFs. The oxidation capability of O2 MP and reduction capability of Ar MP treatments can be beneficial for general materials processing.

Background
Self-assembled GO-based 3D composites with porous or layered architectures have shown distinct qualities in terms of excellent selectivity and high stability. The functionalization of GO with N- and S-rich compounds can enhance its selectivity by increasing active sites for the adsorption of Cd2+.
Method
By decorating GO with 2-mercapto-1,3,4-thiadiazole (MTD), a novel, environment-friendly, and cost-effective 3D MTD@GO2:1/100 °C/2h composite with abundant active sites was successfully fabricated using a convenient facile one-step hydrothermal method. The 3D MTD@GO2:1/100 °C/2h composite demonstrated exceptional selectivity and efficiency in removing Cd2+ from aqueous solutions.
Significant findings
The batch adsorption studies were conducted to enhance the adsorption efficiency of 3D MTD@GO2:1/100 °C/2h composite toward Cd2+ ions, and an excellent adsorption capacity of 37.176 mg∙g-1 was obtained under optimized conditions (t = 40 min, pH= 7, T = 298 K). The adsorption kinetic, isothermal, and thermodynamic studies showed that adsorption data were better demonstrated with the pseudo-second-order model (R2= 0.999), and the Langmuir isotherm model suggested that the heterogeneous, surface chemisorption at monolayer coverage was the rate-limiting step, and the adsorption was endothermic.

Background
As the storage period of eggs extends, their quality declines significantly, highlighting the need for a fast and efficient method for assessing egg quality. This study introduces a Deep Gas Features Calculation Network (DGFCNet) integrated with an electronic nose (e-nose) system to enable accurate egg quality identification across various storage periods.
Methods
The e-nose system, equipped with an array of gas sensors, gathers gas profile data from eggs at different storage periods. A Deep Gas Features Calculation Module (DGFCM) is developed to extract deep gas features that enhance classification result. This module reduces computational complexity through grouped calculations, enhances the representation of deep features via an attention mechanism, and adaptively integrates shallow and deep features with residual dense connections to prevent feature degradation. Based on DGFCM, DGFCNet is designed to identify the gas information of egg.
Significant Findings
DGFCNet achieves egg quality identification at different storage times, reaching 97.30 % accuracy, 97.56 % precision, and 97.47 % recall, surpassing other leading methods in gas information classification. In conclusion, DGFCNet combined with the e-nose system offers an effective technological approach for monitoring egg quality throughout storage.
