Summary: The use of mono-valent selective electrodialysis to adjust the pH of acid leaching solution allows for efficient recovery of sulfuric acid and separation of impurity ions. The technique showed good performance in separating H+ and VO2+ in various vanadium shale acid leaching solutions without Fe3+. The optimization effect of impurity ions on vanadium rejection, water loss, and treatment time was investigated, and the impact of impurity ions on pH adjustment was qualitatively discussed. Selective electrodialysis proved to be a clean and efficient process for treating vanadium-bearing acid leaching solution.

Summary: In order to meet the demands of a growing global population, sustainable, healthy, delicious, and affordable next-generation foods are urgently needed. Polyphenols, abundant in edible plants, have shown great potential as food additives due to their health benefits. However, there are challenges in incorporating polyphenols into food products. This review highlights the post pH-driven (PPD) approach as a viable solution, which is simple, fast, environmentally friendly, and versatile for different polyphenols and food systems.

Summary: The study found that saline lakebed dust is a source of particulate chloride, generating high concentrations of ClNO2, but the underlying physiochemical factors responsible for observed yields are poorly understood. Single particle and bulk techniques showed that trace highly hygroscopic magnesium and calcium chloride minerals may facilitate ClNO2 formation at low humidity. Furthermore, it was discovered that the composition of the aerosol surface, rather than the bulk, is critical in ClNO2 formation.

Summary: Manganese in vanadium slag plays a crucial role and has an impact on the phase of vanadium slag and the synergistic effects during the roasting process. By altering the MnO content, the lattice structure of spinel and olivine in vanadium slag can be modified, leading to different leaching rates of vanadium.

Summary: Investigation on the thermodynamic behavior of vanadium oxide in molten ilmenite smelting slag revealed that the distribution ratio of vanadium increases with F/T ratio and decreases with A/(S+A) ratio. Additionally, the behavior of vanadium oxide suggests it acts as an acidic component in the system.

Summary: This study examines the impact of food packaging cues on perceived product quality in the Pakistani consumer market, taking into consideration the moderating effect of consumer knowledge. The findings suggest that brand name, price, nutritional labels, and precautionary labels have a positive and significant relationship with perceived product quality, while the country of origin does not. Consumer knowledge moderates the relationships of brand name and country of origin with perceived product quality, but has no moderating effect on the relationships of price, nutritional labels, and precautionary labels with perceived product quality.

Summary: This study investigates the electronic structures and optical properties of vanadium-doped cubic C3N4 using first principles calculations. The results show that vanadium doping introduces two intermediate bands around the Fermi level and significantly enhances the light absorption of the material in the UV-visible region.

Summary: The effect of pH on volatile flavor formation during thermal treatment of an Amadori rearrangement product (ARP) was studied with and without the addition of cysteine (Cys). The pH-dependent formation of thiols, sulfides, 2-acetylthiazole, and pyrazines induced by Cys during thermal degradation of ARP was observed. Low pH levels promoted the hydrolysis of Cys to hydrogen sulfide (H2S), resulting in the increase of thiols and sulfides with a meaty aroma. Alkaline conditions enhanced the cyclization or transformation of imine to the enol structure, leading to the formation of 2-acetylthiazole and pyrazines with a roasted and nutty aroma. The combined effect of pH and Cys addition was beneficial for achieving desirable flavors during thermal processing of ARP.

Summary: The complexity and irreproducibility of glycosylation reactions hinder the progress of glycosciences. Applying the steady-state hypothesis to transient oxocarbenium ion-counterion pair intermediates reveals the significance of factors like concentration, temperature in glycosylation stereoselectivity. Guidelines have been proposed for the practice of O-glycosylation reactions, allowing for the establishment of more reproducible and practical protocols.

Summary: The formation of odour-active volatiles in beef is influenced by the contents of type I oxidative and type II glycolytic muscle fibres. Beef composed of more type I fibres had higher levels of 3-methylbutanal and 3-hydroxy-2-butanone, but fewer lipid-derived volatiles, which can be attributed to higher antioxidant capacity, pH, and total heme protein content in type I fibres.

Summary: This study explores the role of source emission in sulfate aqueous formation using chemical thermodynamics and kinetics models and positive matrix factorization models. The results indicate that sulfate formation is mainly through the H2O2 pathway, and secondary nitrate sources may be related to sulfate formation from the H2O2 pathway. The study also finds that coal combustion and vehicle exhaust have significant effects on sulfate aqueous formation, and aerosol acidity plays a key role in sulfate formation.

Summary: Designing tunable molecular systems to host spin qubits, such as photogenerated radical pairs, shows promise for advancing quantum information science applications. DNA, a well-studied molecular system, serves as a tunable scaffold for controlling multispin interactions. By using NDI as the hairpin linker and TEMPO as a stable radical attached at varying distances, significant spin-spin dipolar interactions between the SQP and TEMPO were observed, showing potential for complex spin manipulations in these systems.

Summary: This study explores the role of ligands in altering the lattice parameters and optical properties of CdSe nanoplatelets. Ligand exchange experiments showed that the optical bandgap decreases and the thickness of the nanoplatelets increases. Benzoic acids were found to produce larger optical and structural distortions compared to cinnamic acids.

Summary: The inherent spin polarization in photogenerated spin-correlated radical pairs makes them promising for quantum computing and quantum sensing. In this work, dye molecule-inorganic quantum dot conjugates are prepared and shown to produce photogenerated spin-polarized states. By performing optical spectroscopy and electron paramagnetic resonance experiments, it is demonstrated that the spin states can be accessed and manipulated with microwave pulses. This work opens up possibilities for using highly tailorable inorganic nanoparticles as a new class of qubit materials.

Summary: The study aimed to investigate the impact of social determinants of health (SDOH) on the presentation and management of unilateral vocal fold immobility (UVFI). A retrospective chart review of 207 adult UVFI patients was conducted, and the results showed that patient demographics and socioeconomic status were not associated with time to presentation. However, patients with glottic insufficiency and UVFI due to malignancy or recurrent laryngeal nerve (RLN) sacrifice had a shorter time to presentation. Higher household income was associated with more interventions, but income and insurance type did not affect intervention type or timing. Female patients were less likely to undergo injection medialization laryngoplasty, and older patients were more likely to undergo injection. Patients with large glottic gaps and higher VHI-10 scores were more likely to undergo surgery.

Summary: Computational models accurately predict electronic structure and optical properties of quantum dot materials, but applying these models to core/shell QDs has been challenging. Experimental data on core/shell CdSe/CdS QDs show that core size has a modest impact on radiative recombination rates, contrary to predictions by effective mass models. Empirical modifications are needed to match experimental data, with the relationship between conduction band offset and core size used to create a predictive map of radiative lifetime.
