Summary: Zinc-aluminum layered double hydroxides (ZnAl-LDHs) film was prepared on magnesium alloys with different surface roughness using metallographic preparation combined with the hydrothermal method. The results showed that ZnAl-LDHs film grew most intensely when the surface roughness was at a minimum of 0.094 μm, reaching a thickness of 3.8 μm with a static contact angle of 84.34 degrees and a minimum corrosion current density of 1.12 x 10(-4) A/cm(2). The study also proposed the possible growth and corrosion prevention mechanisms of LDHs films.

Summary: LDH-modified zeolites are effective adsorbents for removing Cr(VI), with zeolites/ZnAl-LDH exhibiting higher removal capacity and adsorption rate. The adsorption of Cr(VI) is a spontaneous endothermic process, with the optimal pH range for efficient removal being 4.0-7.0. The main mechanisms for Cr(VI) removal are electrostatic adsorption and ion exchange.

Summary: ZnLaAl layered double hydroxides (LDHs) were prepared using the co-precipitation method and embedded in a sol-gel coating for corrosion protection of 6061 aluminum alloys. The addition of ZnLaAl-LDHs in the sol-gel coating exhibited higher corrosion resistance and stability compared to ZnAl-LDHs, suggesting that La enhances the anti-corrosion performance of LDHs. Further discussion includes the formation mechanism of ZnLaAl-LDHs and the corrosion mechanism of the sol-gel coating on 6061 aluminum alloys.

Summary: The NiFe-LDHs film was fabricated on Q235 steel using a two-step hydrothermal method, and the superhydrophobic NiFe-LDH-PFDTES film was obtained by PFDTES modification. The structure and composition of the films were analyzed, and their wettability and corrosion resistance in a NaCl solution were evaluated. The results showed that the NiFe-LDH-PFDTES film exhibited excellent corrosion protection with a high contact angle and low sliding angle. The film achieved a superior corrosion resistance compared to the NiFe-LDHs film, indicating its potential for industrial applications.

Summary: Defect engineering and heteroatom doping can enhance the catalytic activity of ZnAl-LDHs in CO2 reduction. By using DFT, we investigated the effects of Zn vacancies, oxygen vacancies, and Cu doping on the geometry and electronic structure of ZnAl-LDH and revealed the reaction mechanism. The results showed that the unsaturated metal complexes formed by V-O, V-Zn, and doped-Cu play a key role in improving the selectivity and activity of CO2 reduction.

Summary: Catalytic oxidation of cyclohexane to cyclohexanol and cyclohexanone with H2O2 was performed using ZnAl or MgAl layered double hydroxides (LDHs) modified with tungstate and molybdate anions as catalysts in heterogeneous medium. The catalysts were prepared by direct anion exchange reactions of tungstate and molybdate on LDHs intercalated with chloride/ carbonate anions. ZnAl-modified with WO42- showed higher activity and selectivity for ketone than MgAl-modified WO42- or any molybdate-based LDH catalysts.

Summary: The effect of ZnAl layered double hydroxides (LDH) on the corrosion resistance of Zn-55Al coating is investigated. The prepared LDH film can effectively inhibit the formation of simonkolleite, hydrozincite, and ZnO in the corrosion product film of Zn-55Al alloy, making it more dense and less prone to cracking, thus preventing corrosion. LDH film can reduce the corrosion current density and improve the electrochemical impedance of pure Zn.

Summary: This study investigates the long-term corrosion protection performance of ZnAl coatings with different aluminum contents. The results show that higher aluminum content leads to lower corrosion rate, with the ZnAl50 coating displaying the best performance. The corrosion rate of ZnAl coatings initially increases with immersion time due to the formation of unstable and porous corrosion product ZnO, but decreases after a certain period of time.

Summary: In this research, high-performance ZnAl-layered double hydroxides (ZnAl-LDHs) with different Zn2+ concentrations were prepared on the surface of an anodized 1060 aluminum alloy. The influence of Zn2+ concentration on corrosion resistance and tribological behavior was explored. The results showed that with the increase in Zn2+ concentration, the thickness and bonding strength of the coatings increased, while the hardness decreased. The ZnAl-LDHs/AAO composite coating with a Zn2+ concentration of 0.3 mol/L exhibited the best anti-corrosion ability and excellent friction-reduction and anti-wear properties.

Summary: Various valid emission control strategies in China since 2013 have significantly improved the particulate matter (PM) pollution. The study investigates the variation trend of nitrous acid (HONO) and its concentration in an urban area of Beijing in the winter. The findings suggest that photo-enhanced NO2 reactions and photolysis of HONO are major sources of HONO in the daytime during winter, and secondary pollutants like HONO have increased despite the decrease in primary pollutants. Therefore, it is important to control HONO concentration to mitigate secondary pollution.

Summary: This study aimed to investigate the immune response-related protein profiling in the plasma of patients with idiopathic inflammatory myopathies (IIMs), especially anti-MDA5+ dermatomyositis (DM). Through Olink proteomics, 46 differentially expressed proteins were detected in IIM patients, including 12 upregulated and 34 downregulated proteins. The immune response-related protein profiling significantly altered in anti-MDA5+ DM patients, with increased levels of LAMP3, HSD11B1, and KRT19, and decreased levels of SH2D1A, ITGA11, TRIM21, CD28, ITGB6, and HEXIM1. KRT19 showed potential as a biomarker for anti-MDA5+ DM patients.

Summary: Gallium alloys were mixed with various substances to obtain low melting point, reduce wetness and adhesion, and achieve low viscosity. Ga80In10Sn10 alloy showed lower wettability and a larger contact angle on a Teflon plate. (Ga80In10Sn10)(97)Zn-3 alloy with a melting point of 8.2 degrees C and higher viscosity than water was developed. It is expected that a temperature-sensitive magnetic fluid can be prepared in the future using gallium-based liquid alloy as the base carrier liquid in a Teflon container for energy conversion.

Summary: The type I interferon (IFN-I) pathway is remarkably activated in patients with inflammatory myopathy, especially in those with anti-melanoma differentiation-associated gene 5 (MDA5) antibodies. Abnormal expression of monocyte subsets and cytokines may contribute to the activation of the IFN signature. The IFN-related genes are correlated with laboratory parameters and helpful for diagnosis of inflammatory myopathy.
