Summary: AISI H13 die steel specimens were subjected to various heat treatments followed by corrosion studies, revealing that the heat-treated specimens exhibited better resistance to corrosion due to lower grain boundary area compared to specimens treated with deep cryogenic treatment. Additionally, both surface modification treatments enhanced the corrosion behavior of the untreated alloy.

Summary: The influence of reaction temperature and time on the interfacial intermetallic compounds (IMCs) in hot dip aluminizing of AISI 321 stainless steel was investigated. The results showed that at 700 degrees C, only a single layer of θ-Fe4Al13 was observed, while at 800-1000 degrees C, the IMCs consisted of an inner layer of η-Fe2Al5 +ζ-FeAl2 adjacent to the steel and a thick outer layer of θ-Fe4Al13 close to the aluminum. The thickness of the inner layer increased with increasing dipping temperature and time, while the thickness of the outer layer varied at different temperatures. Rating: 8 points

Summary: This study found that the wear rate increased significantly (10 times) in hydraulic fracturing fluid with high total dissolved solids compared to distilled water. Mixing organic corrosion inhibitors with high total dissolved solids water can significantly reduce friction and wear response (2-3 fold). The addition of a corrosion inhibitor also synergistically improved wear-corrosion resistance, with the corrosion mitigating efficacy of different inhibitor combinations correlating well with theoretical corrosion kinetics.

Summary: Establishing a liquid-phase isolation layer with MgO islands and liquid phases on the corroded interface of refractories improves corrosion resistance against steel/slag attacks. SiC-additive influences the formation process of the isolation layer by controlling the generation/migration of Mg(g) on the refractory's surface. This liquid-phase isolation layer not only enhances the corrosion resistance of the refractories, but also reduces exogenous pollution.

Summary: This study aims to explore the effects of transformation-induced plasticity (TRIP) induced by cold rolling on AISI 316L grade ASTM F138: 2019, a biomedical material, and its compliance with ISO 5832. Cold rolling of 316L stainless steel is a cost-effective method that provides good surface finish and dimensional accuracy compared to other manufacturing processes. However, the TRIP effect in cold-worked 316L steel can lead to unwanted phases, limiting its use as a biomaterial. Understanding the TRIP effect through cold rolling can enhance its applicability in biomedical engineering.

This study compares the operational performance of two major online ridesharing modes, ridesplitting and carpooling, using actual operating data provided by DiDi Chuxing. The findings indicate that ridesplitting has lower fuel-saving and distance-saving ratios compared to carpooling, and online ridesharing is not considered fuel-saving in terms of transportation system's fuel economy.

Summary: This study aimed to explore the unsatisfactory histologically complete resection (CR) rate of small rectal neuroendocrine tumors (RNETs) and its associated risk factors and clinical outcomes. The study found that polypectomy, a central depression, and treatment in the early period were risk factors for incomplete resection (IR). Further analysis revealed that an atypical hyperemic appearance and treatment in the early period were significant predisposing factors for inappropriate choice of polypectomy.

Summary: Titanium alloys have poor tribological properties, but a ceramic TiO2 layer formed on the surface can greatly improve its performance. Pre-depositing a gold layer on the titanium surface promotes the diffusion of titanium and oxygen to form a compact titanium dioxide layer. The distribution of gold particles enhances surface hardness and reduces friction and wear in tribological tests.

Summary: In this study, a closed-field unbalanced magnetron sputtering system was used to deposit CrSi coatings on 316 austenitic stainless steel. The oxidation behavior of the coatings at elevated temperatures was investigated and the optimized coating for stainless steel protection was identified. It was found that a small amount of Si in Cr coatings effectively protected the stainless steel, while a high Si content made the coating more brittle and prone to damage at high temperatures.

Summary: Nitrogen-expanded austenite (γN), also known as S phase, is a metastable phase that has been extensively studied on AISI 304/316 stainless steel following low temperature N diffusion treatments. Nitrogen absorption and Si segregation were observed on the surface of FeCrNiSi0.5 medium entropy alloy (MEA) after active screen plasma nitriding (ASPN) treatment. The sluggish Cr segregation in the N-modified MEA surface could be attributed to Si-induced nanoprecipitation and the high equimolar Ni/Cr content in the host matrix.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
