Summary: The hot corrosion behavior of a novel Ni16Cr13Co4Mo alloy in molten NaCl-KCl and NaClKCl-Na2SO4 was investigated. The overall corrosion process was controlled by diffusion, and the presence of Na2SO4 promoted the hot corrosion. The composition and properties of the corrosion layer differed in different molten salt environments.

Summary: The high-temperature corrosion characteristics of Inconel 625 and NiCrMoAl cladding layers were studied in molten NaCl-KCl and NaCl-KCl-K2SO4. In NaCl-KCl, the corrosion behavior was primarily controlled by an electrochemical mechanism, followed by a chlorine-active corrosion mechanism. NiCrMoAl cladding layer exhibited significantly higher corrosion resistance than Inconel 625 cladding layer due to the enhanced difficulty of Cl- inward diffusion by the generated Al2O3. In NaCl-KCl-K2SO4, the presence of protective Al2O3 and Cr2O3 worsened the corrosion due to the basic fluxing mechanism. Furthermore, the reaction between Al and SO42- resulted in the consumption of Al and the formation of free S, leading to severe corrosion of the NiCrMoAl cladding layer compared to Inconel 625 cladding layer.

Summary: In order to understand the behavior of lanthanide/actinide ions in solvent salts, molecular dynamics simulations and EXAFS measurements were performed. It was found that the increase in solvent salt polarity led to an increase in the coordination number of ions. This coordination change was validated by the EXAFS measurements. The rigidity of the coordination shell was found to be related to the diffusivity of the ions.

Summary: Wearable sensors can provide important insight into a patient's health status by monitoring the concentration of specific biomarkers in body fluids. The integration of nanoporous metal-organic framework (MOF) particles with nitrocellulose (NC) fibrous layers using an electrospinning approach has been demonstrated, showing the efficiency of the MOF@NC structure as biosensors. The sensitivity and selectivity of this approach make it a promising platform for versatile and adaptable sensing of biomarkers.

Summary: The densities of molten ternary salt systems were estimated using a multidimensional Redlich-Kister model with binary interaction parameters generated through temperature and composition dependent functions. The agreement between the extrapolated densities and experimental data was within 2-11%, showing promising results for thermophysical modeling and potential application in other material properties. Additionally, the modeling method outlined in this study could be extended to quaternary or higher multicomponent molten salt systems.

Summary: This work summarizes a theoretical analysis of how Raman spectra in aqueous NaCl and KCl solutions are perturbed by ion pairs. The experimental results show that polarized and depolarized Raman spectra are similarly affected by these ions, with KCl causing slightly less perturbation than NaCl. This is contrary to molecular dynamics simulations, which predict that the isolated ions of KCl should cause greater perturbation than NaCl due to the larger solvation shell of K+. The discrepancy suggests that ion pair formation is more substantial for KCl than NaCl. MD simulations and quantum chemical calculations confirm that KCl forms more ion pairs than NaCl, and that ion pair formation reduces the perturbation on Raman spectra to a greater extent for KCl. The findings demonstrate that perturbed Raman spectra can serve as a useful indicator for evaluating ion pair formation in aqueous solutions.

Summary: Cascade hydroponics, incorporating basil cultivation as a secondary crop, can improve salt tolerance and water use efficiency in greenhouse crops. Basil plants grown in NFT systems showed higher growth and nutrient uptake efficiency compared to those grown in rockwool, indicating the potential for using basil as a secondary crop in cascade hydroponic systems.

Summary: The corrosion behavior of a commercial grade IN 740H alloy in the eutectic equimolar NaCl-KCl salt mixture at 700 degrees C and 800 degrees C was investigated. The results showed that IN 740H corrodes at rates of 0.29 +/- 0.03 and 0.59 +/- 0.17 mg cm(-2) day(- 1) at 700 degrees C and 800 degrees C, respectively. Electrochemical and gravimetric tests were used to evaluate and understand the early stages of corrosion, and the passive layer was found to not inhibit corrosion at early stages.

Summary: A process combining selective chlorination and molten salt electrolysis was proposed for efficient and environmentally friendly zinc recovery from metallurgical dusts. The electrochemical behavior of Zn2+ on a tungsten electrode in a molten NaCl-KCl eutectic was studied, and the reduction of Zn2+ was found to be a one-step process controlled by diffusion. The electrolytic preparation of zinc in a molten NaCl-KCl-ZnCl2 eutectic resulted in the formation of pure zinc metal. This study provides valuable theoretical reference for the efficient recovery of zinc from metallurgical dusts.

Summary: The electrodeposition of molybdenum in NaCl-KCl-MoCl3 melt was studied utilizing pulsed electrolysis at 780 degrees C. Compact Mo deposits were obtained, and SEM and XRD analysis showed primarily (110) orientation. The influence of deposition conditions on current efficiency was investigated, and optimal parameters were determined, resulting in a 5-fold increase in electrodeposition rate compared to galvanostatic electrolysis.

Summary: The study found that with increasing heat flux, the tensile strength of Kevlar/PBI blended fabrics showed a significant decrease, and the duration of exposure also had an impact on tensile strength. When examining the effects of thermal aging on tensile strength, one must consider not only the maximum temperature that the fabric reaches, but also the complete temperature-time trace.

Summary: The research focused on analyzing spectral data to develop correlations between NIR results and remaining tensile strength of Kevlar(R)/PBI outer shell fabrics after exposures in the cone calorimeter. Among the methods considered, the NDI method showed the most promise as it exhibited clear trends across the fabrics and could be implemented using measurements at two wavelengths for practicality in evaluating firefighters' protective clothing in the field.

Summary: This study investigates the contribution of leaf pigments and surface wax to heat avoidance in pea canopies, and their associations with spectral vegetation indices. Heat stress reduces leaf chlorophyll and carotenoid concentrations, and increases wax concentration. Higher leaf pigment and wax concentrations are associated with lower canopy temperature and higher heat tolerance index.
