Summary: In this study, the effects of heat treatments on the corrosion resistance and bonding strength of stainless steel cladding plate (SSCP) were investigated. It was found that the diffusion of carbon atoms during heat treatment enhanced the bonding strength of SSCP but also caused intergranular sensitization of the cladding surface. Solution treatment was shown to effectively inhibit this sensitization. The SSCP with continuous solution and tempering treatment exhibited the highest bonding strength.

Summary: Laser micro-welding is different from macro-welding due to smaller weld dimensions. Research on the influence of welding modes on microstructure and corrosion resistance is lacking. This study uses a single-mode fiber laser to weld stainless steel foils, and identifies two welding modes: thermal conduction welding and penetration welding. The transient phase of laser-material interaction is caused by oxidation during penetration welding, while gas protection eliminates this phase. The conduction weld exhibits better corrosion resistance due to different heat transfer behavior compared to the penetration weld.

Summary: In this study, 316L stainless steel repaired layers were fabricated on a 27SiMn steel substrate using weld surfacing and laser cladding techniques. The microstructures of the repaired layers were characterized, and their surface properties were measured and correlated with the microstructure features. The laser-cladding repaired layer exhibited superior corrosion and wear resistance, which can be attributed to the laser-induced ultrafast cooling and the formation of denser and finer grain structures.

Summary: The effect of Cu addition on the corrosion behavior of 304 austenitic stainless steel was studied through various tests and analyses. The results showed that 304Cu exhibited higher corrosion resistance than 304 in a NaCl solution, but the beneficial effect of Cu diminished after prolonged exposure. Both penetrating and non-penetrating corrosion pits were observed on both steel types after immersion in a FeCl3 solution, but the corrosion rates of 304Cu were much higher. Cu and Cu2+ were the main forms of Cu in the as-received 304Cu, and Cu+ formed during corrosion in chloride solutions. The study highlights the importance of considering the corrosion resistance of steel in aggressive environments for long-term exposure.

Summary: A reliable solid diffusion bonding between 90 W-7Ni-3Cu tungsten alloy and 304 stainless steel was achieved by using a pure Cu interlayer. The interfaces bonded excellently through mutual diffusion of atoms, without formation of intermetallic compounds or brittle phases. The joint with a Cu interlayer exhibited enhanced tensile strength of 265 MPa, about 58% higher than the joint without a Cu interlayer. Fracture analysis revealed a mixed fracture mode of plastic fracture and intergranular fracture in the Cu interlayer and at the Cu/304SS interface.

Summary: This study investigated the effect of austenite and ferrite phases on the mechanical properties and corrosion resistance of duplex stainless steel weld metals by substituting Ni with Mn, N, and Mn+N. The results showed that maintaining a 50:50 ratio of austenite and ferrite without harmful phases is crucial for performance, while excessive Mn can decrease corrosion resistance. Additionally, replacing Ni with Mn or N can lead to harder austenite, affecting the overall mechanical properties of the weld metal.

Summary: This study investigated the impact of early-life arsenic exposure on mice. The results showed that arsenic ingested early in life is more readily absorbed from the gastrointestinal tract, leading to higher oral bioavailability. Although there were differences in gut microbiota between weanling and adult mice, it did not significantly affect arsenic biotransformation or overall gut metabolite composition. The small intestine of weanling mice had more defined intestinal villi, providing a greater surface area for arsenic absorption.

Summary: Per- and poly-fluoroalkyl substances (PFAS) are of increasing concern as environmental contaminants. The interactions between PFAS and surfaces are important for PFAS transport and remediation. Monte Carlo molecular simulations were used to examine PFAS-surface interactions, showing differences resulting from changes in surface charge, H+, OH-, Ca2+ concentrations, and PFAS carbon chain length. The simulations can aid in the design and testing of sorptive surfaces for PFAS remediation.

Summary: Microplastics exposure is a new human health crisis. The impact of microplastic exposure on the absorption of co-exposure toxic pollutants such as arsenic is unclear. In this study, mice were exposed to arsenate alone and in combination with polyethylene particles to determine the influence of microplastic co-ingestion on arsenic oral bioavailability. The results showed that microplastic ingestion significantly increased arsenic oral bioavailability, possibly by affecting gut microbiota and gut metabolites.

Summary: This study examined the impact of different types of microplastics (MPs) on the bioavailability of hydrophobic organic contaminants (HOCs). MPs released into the soil can exhibit various equilibrium statuses and act as a source, cleaner, or sink for HOCs. Three types of MPs (LDPE, PLA, and PS) were studied for their effect on the relative bioavailability (RBA) of polychlorinated biphenyls (PCBs) using a mouse model. Exposure to MP-sorbed PCBs resulted in their accumulation in adipose tissue, with LDPE showing the highest RBA (101 ± 6.73%), followed by PLA (76.2 ± 19.2%) and PS (9.22 ± 2.02%). When added to PCB-contaminated soil, MPs led to a significant reduction in PCB RBA, particularly LDPE (52.2 ± 16.7%), PLA (49.3 ± 4.85%), and PS (47.1 ± 5.99%), compared to the control (75.0 ± 4.26%), suggesting that MPs act as cleaners by adsorbing PCBs and reducing their accumulation. MPs also acted as a sink for PCBs in aged contaminated soil, with LDPE showing a more pronounced effect than PLA and PS. Therefore, the role of MPs in HOCs' bioavailability depends on the MP types and equilibrium statuses among MPs, soil, and HOCs.

Summary: This study examined the impact of precursors and bioaccessibility on children's exposure to PFAS in house dust from Adelaide, Australia. They found high concentrations of PFAS and significant changes in concentrations after the TOP assay. The bioaccessibility of PFAS was determined and found to be higher for PFCA compared to PFSA. The estimated daily intake of PFAS was calculated, showing a significant decrease when considering dust-specific bioaccessibility values. However, a worst-case scenario analysis showed potential higher exposure levels. Overall, the study highlights the importance of understanding PFAS exposure pathways. Rating: 8/10
