Deep-ultraviolet (deep-UV) nonlinear optical (NLO) phosphates have become a continuing hot spot since the discovery of Ba3P3O10X. Herein, we report two new deep-UV NLO phosphates, KZn(PO3)3 and RbZn(PO3)3, crystallizing in the asymmetric R3 (No. 146) space group with a three-dimensional (3D) network constructed by [PO3]∞ chains and distorted C3v [ZnO6] octahedra. Both compounds exhibit phase-matchable behaviors with relatively strong powder SHG intensities (about 0.6× and 0.7× those of the benchmark KDP) and short deep-UV cutoff edges (<200 nm). First-principles calculations reveal the synergy of the distorted [ZnO6] octahedron and the flexible [PO3]∞ chain that contribute respectively to the d16 value by 14 and 84% in KZn(PO3)3 or 6 and 93% in RbZn(PO3)3. Remarkably, the SHG-active [ZnO6] herein is pointed out for the first time, which offers an unconventional access to the design and searches for deep-UV NLO material candidates.

Experimental liquid−liquid equilibrium (LLE) binodal curves, tie-lines, and plait points were obtained for the PPG400 + salt (K3PO4, K2CO3, and K2HPO4) + H2O systems at T = 298.15 K. The Merchuk equation was used to correlate the binodal data of the investigated systems. Also, the effect of salt on the phase-forming ability has been studied based on the effective excluded volume (EEV) values from fitting the binodal data to the binodal model developed by Guan, and the salting-out abilities of the anions are in the order of PO43− > HPO42− > CO32−, which may be related to the Gibbs free energy of hydration of the ions (ΔhydG). Furthermore, tie-line compositions were correlated using the Setschenow-type, Othmer−Tobias, and Bancroft equations, and the parameters are reported.

Building a proper flexible electrode with high cycling stability, rate capacity and initial coulombic efficiency (ICE) for flexible potassium-ion batteries (PIBs) remains a challenge. Herein, nitrogen/phosphorus co-doped carbon coated FeP nanorods arrays on carbon cloth (FeP@N, P C NRs/CC) as high-rate capable flexible self-supporting anode was successfully fabricated. The composite electrode combines the advantages of FeP nanorods arrays (FeP NRs), carbon cloth (CC) and N, P co-doped carbon shell (N, P–C), which comprehensively improves the electrochemical stability of the flexible electrode, while the open space between FeP nanorods can facilitate electrolyte impregnation and enhance K + transfer, thus effectively elevating the corresponding rate capability. For the FeP@N, P C NRs/CC electrode, it delivers a reversible capacity of 388.8 mA h g −1 at 0.5 A g −1 up to 400 cycles. Even at 1.5 A g −1 , it can still achieve a remarkable rate capacity of 346.9 mA h g −1 . Moreover, the assembled soft-packed cell can always light the LED lights when it is bent at different angles, which exhibits excellent mechanical flexibility.

Despite the fact that nonlinear optical (NLO) crystals such as AgGaS2 and AgGaSe2 have been widely used in the infrared (IR) range due to their large second harmonic generation (SHG) coefficients and wide range of IR transparency windows, the small laser-induced damage threshold (LIDT) remains a great issue hindering their high-power applications. Herein, three noncentrosymmetric (NCS) chalcogenides AZn4Ga5Se12 (A = K, Rb, or Cs) are successfully obtained through an appropriate flux method after the extensive design and synthesis of the A/Zn/Ga/Q system. Single-crystal X-ray diffraction data demonstrate that they adopt trigonal space group R3 (No. 146) with three-dimensional diamond-like frameworks composed of [M9Se24] layers (M = Zn or Ga) stacking in the same direction and filled by charge-balancing A+ cations. Noticeably, they all exhibit strong powder SHG responses (2.8–3.7 × AgGaS2) and amazing LIDTs (19.2–23.4 × AgGaS2). In addition, theoretical calculations are performed to further determine the relationship between NCS structures and NLO properties. This work provides effective solutions for overcoming the trade-off between strong SHG and high LIDT in IR-NLO materials.

The solid-liquid equilibria of the quinary system LiCl–NaCl–CaCl2–H3BO3–H2O with sodium chlorine saturated at 323.15 K were studied by the isothermal dissolution equilibrium method. Based on the measured experimental solubility data, the dry-salt phase diagram, water content diagram, and sodium chloride content phase diagrams were plotted. The dry-salt phase diagram in this system consists of one invariant point saturated with LiCl·H2O, CaCl2·2H2O, and H3BO3, three univariant curves, and three crystallization regions saturated with NaCl corresponding to CaCl2·2H2O, LiCl·H2O, and H3BO3. No solid solution was found in the system. The areas of crystallization zones increase according to the above order. The Jänecke index of H2O and NaCl and the refractive index change regularly with the Jänecke index of LiCl. The calculated refractive indices agree well with the experimental data using the semiempirical equation. These results on phase diagrams of the quinary system can supply theoretical references for lithium salts and boric acid separation from calcium chloride-type brine.

High-quality lead-free piezoelectric x Mn-doped (K 0.48 Na 0.52 ) 0.985 Li 0.015 NbO 3 films (KNLN; x = 0, 0.01, 0.02, 0.03) were successfully deposited onto Pt(111)/Ti/SiO 2 /Si(100) substrates by sol–gel method. Effects of Mn substitution on the microstructure, dielectric properties, ferroelectric properties, and leakage current of the KNLN films were investigated in detail. Mn-doping can significantly improve the ferroelectric properties and decrease the leakage current of KNLN films. Optimal dielectric properties were obtained in films doped with 2 mol% Mn, whose dielectric constant and dielectric loss at 1 kHz were 875 and 0.030, respectively. In addition, well-saturated ferroelectric P - E hysteresis loop with large remanent polarization (2 P
r ) and coercive field ( E
c ) of 22.5 μC/cm 2 and 65 kV/cm were obtained in 2 mol% Mn-doped KNLN film at an applied electric field of 200 kV/cm.

Liquid–liquid equilibria provide fundamental data for designing and simulating a proper extraction process. The aim of this work is to extract cyclohexanone from wastewater using appropriate solvents. Liquid–liquid equilibrium experimental results were measured for water + cyclohexanone + benzene or methyl isobutyl carbinol ternary systems at 303.15 and 323.15 K under 101.3 kPa. The distribution ratios as well as selectivity values were calculated according to the experimental data to assess the extracting behaviors of the selected solvents. The selectivity value has a slight decrease with the increasing temperature from 303.15 to 323.15 K, which indicates that temperature has an adverse effect and the low temperature is more suitable for extraction. Besides, the consistency and reliability of the obtained experimental results were ascertained by applying both the Hand and Bachman equations. The obtained experimental tie-line data fitted well with the nonrandom two-liquid and universal quasichemical activity coefficient models, yielding root-mean-square deviation (rmsd) values as low as 0.17 and 0.16 for the two models, respectively.

We have determined the solubility of 4,4′-dimethoxybenzophenone (DMBP) in ten monosolvents and three binary solvent mixtures at temperatures ranging from 293.15 to 333.15 K and at atmospheric pressure. The solubility of DMBP in both monosolvents and binary solvent mixtures increases with temperature. The solubility of DMBP is greatest in the solvent benzene and lowest in the solvent methanol. The Apelblat equation is the most suitable equation for DMBP in both monosolvents and binary solvent mixtures, based on the results of our solubility experiment data and the data calculated by the thermodynamic models. The outcomes of the KAT-LSER model indicate that π* and δH play a prominent role in the dissolution behavior of DMBP. The mixing thermodynamic properties (ΔmixG, ΔmixH, and ΔmixS) demonstrate that the mixing process of DMBP is an entropy-increasing and spontaneous process, and whether the process absorbs heat or not is related to the properties of the solvents.

Silkworm pupae, by-product of sericulture industry, is massively discarded. The degradation rate of silkworm pupae protein is critical to further employment, which reduces the impact of waste on the environment. Herein, magnetic Janus mesoporous silica nanoparticles immobilized proteinase K mutant T206M and Mucor circinelloides aspartic protease were employed in the co-degradation. The thermostability of T206M improved by enhancing structural rigidity ( t 1/2 by 30 min and T 50 by 5 °C), prompting the degradation efficiency. At 65 °C and pH 7, degradation rate reached the highest of 61.7%, which improved by 26% compared with single free protease degradation. Besides, the immobilized protease is easy to separate and reuse, which maintains 50% activity after 10 recycles. Therefore, immobilized protease co-degradation was first applied to the development and utilization of silkworm pupae resulting in the release of promising antioxidant properties and reduces the environmental impact by utilizing a natural and renewable resource.

Transport properties, including thermal diffusivity and the Fick diffusion coefficient, are key parameters for optimizing chemical processes and ensuring production safety. In this work, the thermal diffusivity and Fick diffusion coefficient of the n–heptane + n–decane binary mixture were measured by dynamic light scattering at n–heptane amount fractions from 0.25 to 0.75. Measurements were performed along five isobars at 0.1, 2.5, 5.0, 7.5, and 10 MPa. Thermal diffusivity was determined over 298.15–523.15 K, except at 0.1 MPa, where the temperature range was limited to 298.15–373.15 K, while Fick diffusion coefficients were obtained from 298.15 to 373.15 K. The relative expanded uncertainties in thermal diffusivity and Fick diffusion coefficient were estimated to be 0.094 and 0.146, respectively, at a confidence level of 0.95 (k = 2). The effects of temperature, pressure, and composition on thermal diffusivity and Fick diffusion coefficient were analyzed, aiming to offer guidance for optimizing the design of industrial processes and ensuring operational safety and reliability.

This work measured the solubility of tetramethylthiuram disulfide in methanol, ethanol, n-propanol, isopropanol, sec-butanol, n-pentanol, acetonitrile, acetone, 2-butanone, methyl acetate, ethyl acetate, and water by utilizing a static gravimetric method covering the temperature range from 283.15 to 323.15 K under atmospheric pressure. The results demonstrate that the solubility tends to increase monotonously with increasing temperature in each studied solvent. The highest solubility (52.17 × 10–3) is observed in acetone at 323.15 K, and the lowest value (0.1180 × 10–3) is found in sec-butanol at 283.15 K. The solubility of TMTD is roughly ranked as ethanol > sec-butanol > n-pentanol > n-propanol > methanol > isopropanol in alcoholic solvents and acetone > 2-butanone > acetonitrile > methyl acetate > ethyl acetate > water in nonalcoholic solvents. Moreover, the Apelblat and Yaws models were used to correlate the solubility data. The outcomes of deviations and AIC values suggest that the Yaws model could give better fitting effects compared with the Apelblat model. This investigation not only fills the gap in the essential data of solubility for TMTD but also provides a theoretical basis for optimization and solvent screening in its separation and purification process in the pharmaceutical industry.
