Summary: Solutions of weakly coordinating ionic liquids (ILs) in alkyl carbonates have attracted attention due to their green solvents properties, but the understanding of ILs' phase behavior and structure in organic polar solvents is lacking. This study investigates the interactions and nanoscale structure of a specific IL, [BMIm][BARF], in alkyl carbonate solvents. The results show that [BMIm][BARF] is mostly undissociated in these solvents and the presence of rod-like nanostructures in the IL/solvent mixtures. The study also reveals that the self-assembly of nano-sized structures is hindered by slower ion diffusion in alkyl carbonates with lower dielectric constants. The findings have implications in various fields including batteries, catalysis, extraction, and bio-applications.

Summary: This study investigated the flotation of low-quality lignite coal in the presence of different inorganic salts, and found that the addition of kerosene and MIBC improved the flotation effectiveness. Furthermore, it was determined that MgCl2 and CaCl2 salts had a greater impact on lignite flotation than NaCl salt.

Summary: Understanding the interaction of ions with charged silica nanoparticles is crucial for producing gels and determining long term stability. In mixtures, monovalent ions generally follow the Hofmeister series, but divalent ions do not. At pH < 9, mixtures of divalent and monovalent salts follow the normal Hofmeister series, while at pH > 9 a reversal is observed.

Summary: The synthesis of Na2Ti6O13 nanowires was achieved through chemical interaction on the surface of molten aluminum, with the composition and morphology of NTNWs controlled by experimental parameters. Increasing the synthesis temperature can lead to changes in the product phase and sodium concentration in NTNW. The study also found that high-temperature synthesis resulted in NTNW containing reduced Ti3+ atoms, with potential applications in sodium-ion batteries.

Summary: The study found that the type of salt, salt concentration, and solution pH have significant effects on the distribution of ambient organic gases in the atmosphere. Chloride salts exhibit a strong salting-out effect, while sulfate salts induce both salting-in and salting-out behaviors depending on ionic strength and pH.

Summary: The normality of metabolomic data is crucial for statistical analyses, but research on the distribution of metabolomic data is rare. In this study, a comprehensive investigation of metabolomic data distributions was conducted using large-scale datasets. It was found that metabolic features exhibit diverse distribution types that cannot be properly normalized using conventional transformation algorithms. To address this, an adaptive Box-Cox (ABC) transformation, which can improve data normality for various distribution types, was proposed. The ABC transformation showed excellent performance in normalizing skewed metabolomic data, outperforming conventional approaches in simulations and real metabolomic studies.

Summary: This study presents a sensitivity analysis of an aerosol model for ammonium salt particle formation and explores the effects of different input variables on model outputs. The results show that variations in particle size are influenced by HNO3, H2SO4, and temperature. The degree of ammonia slip is driven by temperature and the ammonia ratio. The removal efficiency of HNO3 is very high and is not significantly influenced by the concentration of H2SO4. The variability of model run time mainly depends on variations in temperature, relative humidity, and the ammonia ratio.

Summary: This study investigated the effect of different types and amounts of inorganic-salt early strength agents on the performance of cement paste mixed with an alkali-free liquid accelerator at low environmental temperatures. The results showed that mixing Ca(NO3)2, NaNO3, CaBr2, and NaBr improved the performance of the pastes at low temperatures. Using 1.5% CaBr2 in the mixture showed the most significant improvement in 1 d compressive strength, increasing it from 0.5 MPa to 3.2 MPa and shortening both initial and final setting times. Analysis of the paste hydration products confirmed that nitrate-AFm and bromide-AFm primarily promoted the mixing of an alkali-free liquid accelerator in a lowtemperature environment. Therefore, a mechanism for synergetic improvement of nitrate and bromide was proposed.

Summary: In recent years, nanoparticles have become increasingly important due to advances in their synthesis. This article presents the results of nanoparticle synthesis using electrical glow discharge directly in a salt solution, without the usual influence of air. The nanoparticles were prepared under various experimental conditions and characterized using various techniques. The results showed that some of the particles had higher resistance against agglomeration during storage. The fast camera imaging confirmed the nanoparticle formation mechanism, suggesting that this approach can be used for environmentally friendly nanoparticle production.

Summary: Scalable low-Pt PtCu3 intermetallic oxygen reduction electrocatalysts were synthesized with the assistance of sulfur-containing inorganic salts. The success of the catalyst synthesis relies on the use of inorganic negative bivalent sulfur salts, which form a CuS2 intermediate at low temperatures and facilitate the formation of PtCu3 intermetallic catalyst at high temperatures. The prepared small-sized PtCu3 intermetallic catalyst exhibits high mass-based activity (3.0 A mg(Pt) (-1)), large electrochemically active surface area (74 m(2) g(Pt) (-1)) for oxygen reduction, and outstanding durability (18% mass activity loss after 30,000 cycles).

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: In this study, a near-infrared fluorescent probe HCBG was developed for imaging of alpha-GLC. HCBG exhibited excellent selectivity and sensitivity towards alpha-GLC in complex bio-samples, and showed good cell permeability for in situ real-time imaging. Through the high-throughput screening system established by HCBG, a natural alpha-GLC inhibitor was successfully isolated and identified. This study provides a novel fluorescence visualization tool for discovering and exploring the biological functions of diabetes-related gut microbiota, and a high-throughput screening approach for alpha-GLC inhibitor.

Summary: This study developed a high-performance gas sensor for formaldehyde detection by modifying ZnSnO3 with ZnO QDs and SnO2 QDs. The modified sensor showed improved sensing response and lower working temperature. The presence of ZnO QDs formed rich heterojunctions, increased surface area, and provided oxygen deficiency for formaldehyde sensing reaction, thus enhancing the sensor performance. This research provides an alternative method to enhance the sensing properties of MOS by QDs modification.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
