K-doped Mn–Ce solid solution catalysts were synthesized using a combination of coprecipitation and hydrothermal methods, demonstrating excellent performance in benzene oxidation. The catalyst K 1 Ce 5 Mn 5 exhibited comparable activity to noble metal catalysts, achieving a 90 % benzene conversion at approximately 194 ℃. Durable tests under dry and moist conditions revealed that the catalyst could maintain its activity for 50 h at 218 ℃ and 236 ℃, respectively. Characterization results indicated that the catalyst’s enhanced activity resulted from the weakened Mn–O bonding caused by the introduction of K + , facilitating the activation of oxygen and its involvement in the reaction. CeO x , the main crystalline phase of Mn–Ce solid solutions, provided abundant oxygen vacancies for capturing and activating oxygen molecules for the weakened Mn–O structures. This conclusion was further supported by partial density of state analysis from density functional theory computations, revealing that the introduction of K + weakened the orbital hybridization of Mn3d and O2p. Finally, in situ diffuse reflectance infrared Fourier-transform spectroscopy ( in situ DRIFTS) studies on Ce 5 Mn 5 and K 1 Ce 5 Mn 5 catalysts suggested that the introduction of K + promoted the conversion of adsorbed benzene. Furthermore, intermediate products were transformed more rapidly for K 1 Ce 5 Mn 5 compared to Ce 5 Mn 5 .

Objective Nanoparticles (NPs) hold a great promise in combating rheumatoid arthritis, but are often compromised by their toxicities because the currently used NPs are usually synthesized by chemical methods. Our group has previously fabricated Ångstrom-scale silver particles (AgÅPs) and demonstrated the anti-tumor and anti-sepsis efficacy of fructose-coated AgÅPs (F-AgÅPs). This study aimed to uncover the efficacy and mechanisms of F-AgÅPs for arthritis therapy. Methods We evaluated the efficacy of F-AgÅPs in collagen-induced arthritis (CIA) mice. We also compared the capacities of F-AgÅPs, the commercial AgNPs, and the clinical drug methotrexate (MTX) in protecting against K/BxN serum-transfer arthritis (STA) mice. Moreover, we evaluated the effects of F-AgÅPs and AgNPs on inflammation, osteoclast formation, synoviocytes migration, and matrix metalloproteinases (MMPs) production in vitro and in vivo. Meanwhile, the toxicities of F-AgÅPs and AgNPs in vitro and in vivo were also tested. Results F-AgÅPs significantly prevented bone erosion, synovitis, and cartilage damage, attenuated rheumatic pain, and improved the impaired motor function in mouse models of CIA or STA, the anti-rheumatic effects of which were comparable or stronger than AgNPs and MTX. Further studies revealed that F-AgÅPs exhibited similar or greater inhibitory abilities than AgNPs to suppress inflammation, osteoclast formation, synoviocytes migration, and MMPs production. No obvious toxicities were observed in vitro and in vivo after F-AgÅPs treatment. Conclusions F-AgÅPs can effectively alleviate arthritis without notable toxicities and their anti-arthritic effects are associated with the inhibition of inflammation, osteoclastogenesis, synoviocytes migration, and MMPs production. Our study suggests the prospect of F-AgÅPs as an efficient and low-toxicity agent for arthritis therapy.

Liquid–liquid equilibrium (LLE) data for ternary systems of water + 2,2,3,3-tetrafluoro-1-propanol + anisole/1-octanol were determined at temperatures of 298.2, 308.2, and 318.2 K under 101.3 kPa. The distribution coefficients and separation factors were calculated from experimental LLE data, which indicated that anisole/1-octanol extracted 2,2,3,3-tetrafluoro-1-propanol from aqueous solution with high efficiency. The consistency of the experimental LLE data was assessed by the Othmer–Tobias and Hand equations. Meanwhile, the NRTL and UNIQUAC models were successfully applied to regress and correlate the experimental data, presenting the root-mean-square deviations (RMSD) less than 1.0%. The relevant binary interaction parameters of these two models were also regressed.

The equilibrium solubility of 8-isoquinolinamine in methanol, ethanol, n-propanol, isopropanol, N,N-dimethylformamide (DMF), acetonitrile, acetone, propylene glycol (PG), ethylene glycol (EG), and water, and aqueous mixtures of methanol/ethanol/n-propanol/isopropanol plus water was experimentally measured by the isothermal saturation method at 278.15–323.15 K under 101.2 kPa. The mole fractions of 8-isoquinolinamine in monosolvents were obtained to be maximum in neat DMF. For the four binary mixed solvent systems, the amount of 8-isoquinolinamine dissolved in n-propanol + water is more than that in the other three systems. The mole fractions of 8-isoquinolinamine in pure solvents were correlated using the Apelblat model, van’t Hoff model, and Wilson model, and the calculated value of the Apelblat model was the closest to the experimental value. The Jouyban–Acree model, modified Apelblat–Jouyban–Acree model, and van’t Hoff–Jouyban–Acree model were applied to calculate the solubility of 8-isoquinolinamine in the four solvent mixtures. The feedback obtained by comparing the experimental data with the calculated data is that the calculated data from the Jouyban–Acree model was relatively close to the experimental results. Solvent effects as a powerful tool can be used to estimate interactions at the molecular level, and the results showed that solvent–solvent intermolecular interactions contribute to dissolution. van’t Hoff plots are adopted as a method to show the relationship between ln(x) and 1/T.

Liquid–liquid equilibrium data (LLE) of ternary systems {water + 1-butanol + 1-hexanol} and {water + 1-butanol + 1-octanol} were investigated at 303.15, 313.15, and 323.15 K at 101.3 kPa. The distribution coefficient (D) and selectivity factor (S) were calculated from experimental LLE data. Meanwhile, the effect of temperature on the two-phase zone of the two systems was discussed. The nonrandom two liquid and universal quasi-chemical activity coefficient models were used to regress experimental data sets and generate the relevant binary interaction parameters. Both thermodynamic models provided similar good descriptions for the studied systems with root mean square deviations between the calculated and experimental values less than 0.3%.

The porous graphitic carbon nitride nanosheets (PCNSs) with high yields were synthesized by using one–step chemical exfoliation method. PCNSs accelerated separation efficiency of photo-generated electron−hole pairs in comparison to bulk graphitic carbon nitride. The PCNS5 (exfoliation for 5 h) exhibited optimal photocatalytic disinfection capability towards Escherichia coli K-12 under simulated solar light irradiation with complete disinfection of 6.5 log 10 cfu/mL of E. coil K-12 within 2 h. The enhanced photocatalytic activity of PCNS5 originated from mesoporous nanosheet structure. The possible mechanism of photocatalytic disinfection has proposed that intracellular reactive oxygen species levels and the activities of antioxidant enzymes (e.g., catalase and superoxide dismutase) were enhanced. Transmission electron microscope images observed during photocatalytic disinfection process suggested that the cell membrane was regarded as the first target for oxidation, resulting in a faster leakage of cytoplasmic content and finally degradation of DNA leading to bacterial death. Furthermore, the trapping experiment showed that superoxide radical (•O 2 − ) and holes (h + ) were responsible for E. coli K-12 disinfection by PCNS5.

In this study, densities of the two ternary aqueous solution systems (LiB 5 O 8 + LiCl + H 2 O) and (LiB 5 O 8 + Li 2 SO 4 + H 2 O) were measured using an accurate digital vibrating-tube densimeter from 283.15 to 363.15 K at an interval of 5 K and 101.325 kPa. B 5 O 8 - in aqueous solution was in the form of [B 5 O 6 (OH) 4 ] - . Therefore, the complex aqueous solution of LiB 5 O 8 is in the form of Li[B 5 O 6 (OH) 4 ]. Subsequently, the mean apparent molar volume ( V Φ θ ) and mixing ion-interaction parameters ( θ a , a ′ v and Ψ c , a , a ′ v , c = Li + , a = B 5 O 6 (OH) 4 - , a ′ = Cl - or SO 4 2- ) against temperature were obtained using the Pitzer equation for the first time. And then, the temperature-dependence equations for the Pitzer mixing ion-interaction parameters and the relevant temperature correlation coefficients of the equation a j, i.e. [ f ( a i , T ) = a 1 + a 2 ln( T /298.15) + a 3 ( T − 298.15) + a 4 /(620 − T ) + a 5 /( T − 227)] were also obtained through the least square fitting. These volumetric properties and parameterization Pitzer parameters obtained in this work could hopefully be used for the quantitatively predictive calculation of the physicochemical properties of the mixed electrolytes containing lithium, chloride, and sulfate ions at any temperature.

Biofuel may be an important component of aviation fuel for its significant advantages. In the present work, two biofuel samples, methyl laurate and pinane, are selected for blending research with n-dodecane, a typical model fuel of aviation kerosene. Densities and viscosities for the ternary system pinane (1) + n-dodecane (2) + methyl laurate (3) and corresponding binary systems have been measured at the temperatures from 293.15 to 333.15 K and atmospheric pressure. The excess molar volume (VmE) and viscosity deviation (Δη) of binary systems have been calculated based on experimental data and fitted to the Redlich–Kister equation, while those of the ternary system have been fitted to Nagata–Tamura, Redlich–Kister, Cibulka, and Singh semiempirical equations, respectively. The values of the excess molar volume are all positive for all investigated systems, while the viscosity deviations are all negative. The results are discussed from the perspective of intermolecular force and the structure. Furthermore, the densities and viscosities of both binary and ternary mixtures are satisfactorily correlated using the Jouyban–Acree model.

All-inorganic lead halide perovskite nanocrystals (NCs) as new emerging semiconducting luminescent materials have attracted tremendous attention for designing optoelectronic devices . We have synthesized high quality of the CsPbX 3 NCs with tunable entire visible spectral region by a modified lower temperature method, featured with facile, low-cost and easily operating in an open environment without vacuumization or glovebox system. Besides, we have investigated the incorporation of Ni and K ions into CsPbX 3 NCs by adjusting all kinds of composition concentration from halogen salts, based on above mentioned preparation method. The absolute photoluminescence quantum yields (PLQYs) of doped CsPbX 3 NCs with different dopant (Ni or K ions) concentration were discussed. It is found that a certain amount of doping is beneficial for suppressing the defects and improving the lattice structure of nanocrystals, whereas an excessive dopant may induce quenching centers of the emission. In addition, a glorious absolute PLQYs of doped CsPbX 3 NCs can be obtained by our method, especially for CsPbBr 3 and CsPbI 3 NCs, and nearly reach 80%.

Experimental solubility data of dibenzoylmethane (DBM) in three pure solvents (ethyl acetate, acetonitrile, methylbenzene) and three binary solvents (methanol + water, ethanol + water, and isopropyl alcohol + water) were measured by the gravimetric method from 278.15 to 318.15 K under atmospheric pressure. The experimental results showed that the solubility of DBM increased with the increase of temperature. Moreover, the solubility of DBM was temperature-dependent when the type and composition of solvents remained unchanged. The solubility of DBM decreased with the increase of solvent polarity because the molecular structure of DBM was not conducive to the formation of hydrogen bonds between solute and solvent molecules. The solubilities of DBM were correlated by the modified Apelblat equation, the van’t Hoff equation, the λh equation, and the NRTL equation. The modified Apelblat model produced the best fitting results among these models.

According to the composition characteristics of lithium, potassium, bromine, and other resources rich in the salt lake brine of the Qinghai–Tibet Plateau, the phase equilibria of the quaternary system LiBr-NaBr-KBr-H2O and its ternary subsystem LiBr-KBr-H2O at 323.15 K are studied by an isothermal dissolution equilibrium method. The solubility of each system in equilibrium solution at the corresponding temperature is measured, and the corresponding phase diagrams are drawn according to the phase equilibrium experimental data. The results show that there is no complex salt or solid solution in the ternary system LiBr-KBr-H2O at 323.15 K. The phase diagram contains one invariant point (E1), two univariate curves (AE1 and BE1), and two equilibrium solid crystallization regions (corresponding to LiBr·H2O and KBr), belonging to the simple cosaturated type. The quaternary system LiBr-NaBr-KBr-H2O also has no formation of complex salt and solid solution. The phase diagram contains two invariant points (F1 and F2), five univariate curves (E1F1, E3F1, F1F2, E2F2, and E4F2), and four equilibrium solid-phase crystallization regions (corresponding to LiBr·H2O, KBr, NaBr·2H2O, and NaBr). At the same time, to further explain the phase equilibrium relationship of each system at different temperatures and the change rule of each component, comparison and discussion are carried out.

The construction of a comprehensive thermodynamic model for boron-containing salt brine is important. However, the general lack of the solubility of H 3 BO 3 + salt + H 2 O ternary systems makes it difficult to determine model parameters involving boron species. Here, we systematically determined the solubility isotherms of the H 3 BO 3 + CsCl + H 2 O system at T = (273.15, 298.15, 323.15, 348.15 and 363.15) K. There are three solubility branches corresponding to H 3 BO 3(cr) , CsCl (cr) and a novel adduct in the system. The determined composition of the adduct is 2H 3 BO 3 ·3CsCl. Moreover, the single crystal structure of 2H 3 BO 3 ·3CsCl is solved, suggesting that H 3 BO 3 molecules keep it native plane-triangle structure, but the O atoms coordinate to the Cs ion. We modeled these ternary solubility isotherms using the Pitzer-Simonson-Clegg (PSC) model implemented in the ISLEC program. With the help of the model, a complete polythermal phase diagram of the system was constructed for the temperature range from 250 K to 373.15 K. The determined standard thermodynamic quantities of 2H 3 BO 3 ·3CsCl (cr) from the model are Δ f G m Θ = − 3182.26 kJ∙mol −1 , Δ f H m Θ = − 3496.19 kJ∙mol −1 , S m Θ = 485.85 J∙K −1 ∙mol −1 , C p , m Θ = 320 J∙K −1 ∙mol −1 , respectively.
