Summary: This research examined the corrosion behavior and susceptibility to stress corrosion cracking (SCC) of a high-pressure die-cast secondary AlSi9Cu3(Fe) alloy in 3.5% NaCl solution. Various testing methods revealed the presence of critical surface segregation zones, where strong corrosion attack occurred due to composition differences and peculiar morphology of noble Al2Cu phases. No SCC susceptibility was detected, but localized corrosion attack and hydrogen gas bubbling were observed at the interphases of noble phase/alpha-Al matrix.

Summary: Ultrasensitively selective detection of trace polycyclic aromatic hydrocarbons (PAHs) like phenanthrene (PHE) is achieved by constructing atomically dispersed Zn sites on g-C3N4 nanosheets through thermal polymerization of a Zn-cyanuric acid-melamine supramolecular precursor. The resulting sZn-CN exhibits a wide detection range, ultralow detection limit, and ultrahigh selectivity toward PHE based on the PHE-CN dual ratiometric fluorescence method. The superior detection performance is attributed to the selective adsorption of PHE on the atomic Zn(II)-N-5 sites and the fluorescence quenching mechanism involving the inner filter effect (IFE) and photogenerated electron-transfer process.

Summary: Inspired by natural photosynthesis, the rational design of efficient S-scheme heterojunctions holds promises for CO2 conversion by utilizing solar light. Nitrogen-rich doped 001-exposed anatase nanosheets (NPT) were designed and fabricated, and then controllably coupled with copper phthalocyanine (CuPc) to construct a wide-visible-light responsive heterojunction for efficient CO2 conversion. The optimized CuPc/NPT heterojunction achieves a high production rate of CO under visible light irradiation, with a 9-fold enhancement compared with generally N-doped TiO2.

Summary: The size and geometry of supported metal ensembles are crucial in the design of effective heterogeneous catalysts. In this study, supported single atomic-layered, low-nuclearity palladium catalysts were created using an electronic and structural engineering strategy. These atomically dispersed Pd catalysts exhibited excellent catalytic activity in the hydrogenation of levulinic acid to 1,4-pentanediol, a reaction of importance for biomass conversion. Theoretical calculations revealed that the high catalytic activity was a result of cooperation between adjacent Pd atoms and strong electronic metal-support interactions.

Summary: This study aimed to identify, characterize, and analyze the expression profiles of R2R3-MYB genes in Populus euphratica (P. euphratica) during seed germination in response to drought stress and abscisic acid (ABA) treatment. Comparative genomics analysis identified 174 PeR2R3-MYB genes, many of which underwent whole genome duplication or segment duplication events. The expression data supported the hypothesis that PeR2R3-MYBs are involved in drought response through the ABA signaling pathway, especially those with MYB binding sites and/or tandem duplication. This study provides valuable insights for understanding the functions of R2R3-MYBs in P. euphratica and lays the foundation for breeding strategies to enhance drought tolerance.

Summary: The key to developing highly active α-Fe2O3-based photocatalysts is to improve charge separation and effectively utilize high-energy electrons. In this study, α-Fe2O3 nanosheets (FO) were synthesized and coupled with SnO2 nanosheets (SO) to obtain SO/FO nanocomposites. Silver nanoparticles were then loaded on SO to form Ag-SO/FO nanocomposites. The optimized nanocomposite showed efficient degradation of 2,4-dichlorophenol and was also applicable to the degradation of other organic pollutants and CO2 reduction under visible-light irradiation. The enhanced photoactivity of Ag-SO/FO is mainly attributed to improved charge separation by introducing SO as an electron platform and the cocatalytic effect of nanosized Ag.

Summary: Constructing efficient heterojunctions, particularly with additional organic constitution, is highly desired to enhance the photogenerated charge separation of g-C3N4 for solar-hydrogen conversion. In this study, g-C3N4 nanosheets were controllably modified with nano-sized poly(3-thiophenecarboxylic acid) (PTA) and coordinated with Fe(III), forming tightly contacted nanoheterojunctions. The resulting optimized nanoheterojunction exhibited a significant enhancement in visible-light photocatalytic H2 evolution activity. The improved photoactivity was attributed to the promoted charge separation and transfer of high-energy electrons, dependent on hydrogen bond interaction and coordination with Fe(III).

Summary: Salt leaching has been widely used to increase crop production in saline-alkaline soils. However, the effects of leaching patterns on soil ion composition and cotton yield under mulched drip irrigation are poorly understood. This study investigated the impact of different leaching amounts and timings on soil ions and cotton yield. The results showed that increasing leaching amount significantly reduced soil ions and improved cotton yield. The optimal leaching pattern was determined as 225 mm leaching amount at seedling and budding stages.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.
