LiquidLiquid Phase Separation of Viologen Bistriflimide/Benzene Mixtures: Role of the Dual Ionic and Organic Nature of Ionic Liquids
No full textLiquid-liquid phase separation occurs at room temperature when mixing an excess of benzene with solid viologen bistriflimide salts with various alkyl side-chain lengths. A liquid phase composed of (almost) pure benzene is above the other sponge-like liquid phase with salt absorbed in benzene. Nuclear magnetic resonance experiments indicate that the mole ratio of benzene/salt in the sponge-like phase remains unchanged upon varying the amounts of (nonexcessive) salt or benzene. Moreover, the benzene/viologen salt mole ratio in the sponge-like phase increases linearly with respect to the side-chain length of the cation. Similarly, when an excess of viologen salt is added in benzene, a sponge-like liquid phase composed of salt absorbed by benzene is observed in equilibrium with some solid viologen salt neither dissolved nor absorbed by the solvent. The mole ratio of the sponge-like liquid phase again increases linearly with side-chain length, while it remains independent of the relative amount of benzene and viologen salt as long as the latter is in excess. Finally, when appropriate amounts of benzene and viologen salt are mixed, a single sponge-like liquid phase is observed at an intermediate composition between the lower and upper limits. Molecular dynamics simulations reveal that because of their dual ionic and organic nature, when absorbed in benzene, the studied salts form nanoscale segregated liquid structures, akin ionic liquids, with a continuous polar network composed of anions and cationic charged groups, along with nonpolar domains composed of alkyl cationic side chains. Benzene molecules are preferentially absorbed inside the nonpolar region, which effectively expands the nonpolar region to be sponge-like and consequently liquidizes the viologen salt. The linearity of the benzene/salt ratio in the upper and lower phase boundaries comes from the fact that the effective volume of the nonpolar region for accommodating benzene molecules grows linearly with cationic alkyl side-chain length. The occurrence of the above phenomena is attributed to the nonpolar feature of benzene molecules, and there is no evidence of pi-pi or ion-pi interaction between the ions and benzene molecules. Moreover, the diffusion of benzene in the sponge-like phase is found to be close to that in n-alkanes, supporting the idea of nanoscale segregation of polar and nonpolar regions in the sponge-like phase. The revealed mechanism is anticipated to be general for understanding liquid-liquid phase separation observed in mixtures of organic salts (ionic liquids) having relatively long alkyl chains with small organic molecules

No full textDetermination of Minimum Data Set for Soil Health Assessment of Farmlands under Wheat–Maize Crop System in Yanting County, Sichuan, China
No full textThe assessment of soil health through a robust index system having a sufficient number of indicators is an important step toward sustainable crop production. The present study aimed at establishing a minimum data set (MDS) from soil functional and nutritional attributes using a dual index system to evaluate the soil health of farmlands under wheat (Triticum aestivum)–maize (Zea mays) crop rotation in Yanting County, Sichuan, China. Farms from 10 villages in the study area were selected, out of which three sites were considered healthy/ideal sites and used as a reference for the remaining seven targeted sites, and soil samples were collected at depth of 20 cm from these farms. The MDS indicators were selected by using principal component analysis (PCA) followed by Pearson’s correlation on 25 attributes. Based on significant values, eight attributes were retained in the final MDS, including the sucrase level, pH, wilting coefficient, water holding capacity, organic matter, NK ratio, total potassium, and available phosphorus. Based on the results, most of the farmland soils in Yanting County were in a healthy condition, accounting for 61.71% of the surveyed samples, followed by sub-healthy, degraded, and weak soils, accounting for 19.64%, 9.71%, and 8.93%, respectively. The values of most of the indicators at the targeted sites were significantly lower than those at ideal sites. Thus, specific steps should be taken by adding soil organic matter, combined with other fertilizers, to enhance the microbial biomass, enzymatic activities, and other biological activities in the soil
Impulsivity in patients with obsessive-compulsive disorder: exploring the mediating effect of cognitive emotion regulation strategies and depressive symptoms
No full textBackgroundThe underlying mechanism of impulsivity in obsessive-compulsive disorder (OCD) patients is complex and still unclear. Previous studies have not thoroughly explored whether impulsivity in OCD patients is a result of the obsessive-compulsive symptoms themselves or other contributing factors. This study aimed to explore whether cognitive emotion regulation strategies and depressive symptoms mediate the relationship between the severity of obsessive-compulsive symptoms and impulsivity in a clinical population with OCD.MethodsThis was a case-control study that recruited 65 OCD patients (male/female=31/34) and 65 healthy controls (male/female =23/42), matched for age, gender, and education level. Demographic and clinical data were collected, and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Beck Depression Inventory-II (BDI-II), Barratt Impulsiveness Scale-11 (BIS-11) and Cognitive Emotion Regulation Questionnaire (CERQ) were adopted.ResultsOCD patients scored higher on BIS-11 attentional and non-planning impulsiveness and total scores (all p < 0.05). On CERQ, OCD patients showed elevated maladaptive strategies (self-blame, rumination, catastrophizing, blaming others) and reduced adaptive strategies (positive reappraisal) (all p < 0.05). Attentional impulsiveness positively correlated with OCD severity, depression, and maladaptive strategies (all p < 0.05). Non-planning impulsiveness and BIS-11 total scores positively correlated with depression and negatively with adaptive strategies (all p < 0.05). After adjusting for age, gender, depression level, there was only a significant negative correlation between BIS-11 non-planning impulsiveness and CERQ maladaptive strategies (r = -0.28, p < 0.05). Mediation analysis revealed significant indirect effects of OCD severity on impulsivity via adaptive strategies/depression (β = 0.13, 95% CI: 0.03~0.24, p = 0.012) and via maladaptive strategies/depression (β = 0.09, 95% CI: 0.00~0.23, p = 0.042), but no significant direct or total effects.ConclusionsOCD symptom severity indirectly influences impulsivity through emotion regulation strategies and depressive symptoms, highlighting the need to target these mediators in clinical interventions
