The high protein content of Oncorhynchus mykiss , despite its nutritional value, poses a risk of microbial contamination and foodborne illnesses in fresh products, thus necessitating paramount importance for effective preservation. In this study, a synergistic preservation system possessing both antimicrobial and antioxidant functions was developed from pomelo peel. Enzyme-like material with peroxidase-like activity (K/Fe-PP) were synthesized from pomelo peel, KCl and FeCl 3 via a hydrothermal method. These enzyme-like materials catalyze the continuous generation of hydroxyl radicals (▪OH) from H 2 O 2 , enabling sustained bacterial inhibition. An ethanol extract of pomelo peel, harnessing the strong reducing power of its enriched phenolic compounds, was used to inhibit lipid oxidation in fish. To realize their synergy, the K/Fe-PP and the pomelo peel extract were added into a chitosan matrix, which served as a carrier, and were subsequently fabricated into a composite cling film (CS/K/Fe-PP).CS/K/Fe-PP films were applied to Oncorhynchus mykiss under refrigerated storage. The spoilage of Oncorhynchus mykiss was assessed by the value of malondialdehyde (MDA), acid value, total volatile basic nitrogen (TVB-N), histamine content, and total viable count (TVC). It was shown that the optimal cling film extended the storage time of Oncorhynchus mykiss by 3–6 days. This work not only provides a new strategy for applying catalysis based on enzyme-like materials in aquatic product preservation but also establishes a sustainable approach for the high-value utilization of waste biomass resources.

Cr 3+ -activated phosphor has become the mainstream choice to obtain broadband near-infrared phosphor-converted light-emitting diodes (NIR pc-LED) for the applications of bio-imaging and component nondestructive detection. However, exploring efficient and stable Cr 3+ -activated NIR phosphors is still an important yet formidable challenge. Herein, a series of Na y K 3- y LiMg 4 (Si 2 O 5 ) 6 :Cr 3+ phosphors was synthesized, which exhibits a broadband emission spectrum spanning 650-1100 nm. Utilizing the innovative non-main lattice substitution strategy, the internal quantum efficiency (IQE) of Cr 3+ was enhanced from 21% to 80%, and thermal stability was also improved from 42% to 70%@150 °C. Based on the first-principles theory calculation, the IQE and thermal stability improvement are attributed to the strengthened local structure stability around Cr 3+ caused by the introducing of Na + . Finally, a NIR pc-LED device was packaged by combining the optimized Na 3 LiMg 4 (Si 2 O 5 ) 6 :4%Cr 3+ phosphor with blue LED chip, which demonstrates potential applications in biological imaging and night vision systems.

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.

To obtain the basic data for the recovery of 1-methylimidazole from wastewater by extraction, the ternary liquid–liquid phase equilibrium data of the water (1) + 1-methylimidazole (2) + 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) (3) system were determined using an equilibrium autoclave at the temperatures of 303.15 to 323.15 K and 101.32 kPa. The solute distribution coefficient (D) and the selectivity (S) of the ternary system were calculated in accordance with the experimental data. Their values were up to 1.39 and 41.17, respectively, which showed that the ionic liquid can extract 1-methylimidazole effectively. The experimental results showed that the temperature had a slight effect on the liquid–liquid equilibrium behavior. Meanwhile, the calculated results revealed that the selectivity coefficient decreased with the enhancing concentration of 1-methylimidazole in the ternary system and the increasing temperature. In addition, the nonrandom two liquid (NRTL) model was used for correlation of the ternary systems. The root-mean-square deviation value of 0.0218 indicated that the calculated results using the model were in good agreement with the experimental data and were reliable to apply to practice.

Host–guest interactions by artificially synthesized macrocyclic molecules, such as cucurbit[n]uril (CB[n], n refers to the number of glycoluril units), exhibited comparable affinity to natural biological interactions, offering orthogonal selectivities. These unique high-affinity interactions are crucial in bioseparation, particularly in the separation of complex biomacromolecules. However, to date, the application of supramolecular systems in bioseparation remains insufficient and challenging. In this work, a site-specific host–guest interaction-based method by CB[6] and CB[7] was developed for the selective enrichment of basic peptides, and their recognition for basic lysine/arginine (K/R) residues exhibited distinct selectivity. Although they both exhibited affinity to basic peptides, CB[6] tended to bind to peptides containing multiple K/R residues, while CB[7] preferred to adsorb peptides containing both phenylalanine residues and basic K/R residues. This difference was attributed to their distinct cavity sizes. Furthermore, CB[6]-containing monolith was employed for the enrichment of basic peptides from mouse liver sample digested with Staphylococcus aureus protease V8 (Glu-C). It is noteworthy that basic peptides containing 3–4 K/R residues can be successfully enriched, whereas those with more than 5 K/R residues cannot be effectively eluted. It was also observed that 1043 unique peptides were newly identified from 2.5 μg of mouse liver after the capture of basic peptides, with a markable increase in the identification coverage (31%). These newly identified peptides are generally more acidic and shorter than those depleted by CB[6], with median isoelectric point (pI) values of 5.8 and 7.0 and median lengths of 10 and 16 amino acids, respectively.

The solubility of 2′,4′-dihydroxyacetophenone (2′,4′-DHAP) in 10 monosolvents (methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, methyl acetate, ethyl acetate, propyl acetate, and benzene) and two binary solvents (ethanol + ethyl acetate and n-propanol + ethyl acetate) was determined using a gravimetric method at 101.3 kPa from 293.15 to 333.15 K. The experimental solubility was demonstrated to increase with the increasing temperature. The solubility of 2′,4′-DHAP is the highest in pure isopropanol, and the two binary solvents present a solubilizing effect on the solute. Furthermore, six thermodynamic models were employed to fit the solid–liquid equilibrium data, and the correlation results manifested that the modified Apelblat model had minimum ARD values of less than 1%. Finally, the KAT-LSER model was employed to analyze the solvent effect at 298.15 K. The results show that the contribution of the four interaction types α, β, π*, and δH account for 15.84%, 15.30%, 18.33%, and 50.53% of the total interaction force, respectively, and the solvent–solvent interaction represented by δH is the dominant factor affecting the solubility of 2′,4′-DHAP.

Building an interconnected filler network is the most effective way for polymer composites to attain a high thermal conductivity while minimizing the amount of fillers. However, previous approaches for network construction either have to be performed ex situ or rely on magnetic or electrical fields to achieve in situ formation, limiting their practical applications. Here we report a novel strategy to fabricate the filler network in situ without the assistance of any external fields. Thermally expandable microspheres (EMs) are added to the composite and their expansion at elevated temperature forces the conductive fillers to concentrate and align along the boundaries between adjacent microspheres, forming a continuous and densified 3D network. The obtained boron nitride nanosheet (BNNS)/EM/polydimethylsiloxane (PDMS) composite has a low density (0.55 g cm−3), low dielectric constant (<2.3), and excellent flexibility, while still exhibiting a high thermal conductivity of 0.94 W m−1 K−1 (9.82 vol% BNNS), which is 3.1 times that of randomly distributed ones. In addition, it has a low interface thermal resistance (20.93 mm2 K W−1), only 1% of that of the assembled structure. These comprehensive properties make the composite ideal for thermal management of aerospace devices, high frequency electronic devices, and wearable electronics.

The absorption refrigeration system (ARS) was important for energy saving, which can be driven by low-grade energy. In this work, the mixtures of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) + N-methyl-2-pyrrolidone (NMP) and R1234ze(E) + triethylene glycol dimethyl ether (DMETrEG) were considered as the promising new working fluids for ARS. The vapor–liquid equilibrium (VLE) data of R1234ze(E) + DMETrEG and R1234ze(E) + NMP binary mixtures were measured using a liquid-recirculation apparatus from 293.15 to 353.15 K. The VLE data were correlated by the five-parameter non-random two-liquid activity coefficient model, and the correlated results showed a good agreement with the experimental VLE data. The average absolute relative deviation and maximum absolute relative deviation of the pressure were 1.70 and 5.11% for R1234ze(E) + NMP and 1.30 and 3.22% for R1234ze(E) + DMETrEG, respectively. The two binary mixtures exhibited positive deviations from Raoult’s law.

Transport properties of n-pentane are so scarce that it prevents the further studies of n-pentane as an important component of industrial fluids, especially in the near-critical and supercritical regions. In this work, the thermal diffusivity of n-pentane was measured by the dynamic light scattering method within the temperature limits of (293–573) K along six isobaric lines at p = (0.1, 3.0, 3.5, 5.0, 7.5, and 10.0) MPa. The relative uncertainty of the thermal diffusivity experimental system is estimated to be 2.6% for a coverage factor of k = 2 with a level of confidence of 0.95. The influences of temperature and pressure on thermal diffusivity were presented. Besides, we compared the experimental data with the calculated values from the thermal conductivity model proposed by Vassiliou et al. and the multiparameter equation of state proposed by Span and Wagner. The absolute average of relative deviation and maximum deviation between the experimental data and the calculated results are 1.12 and 3.74%, respectively.

Densities and viscosities of ternary system (1-pentanol + ethylcyclohexane + methyl myristate) and the corresponding binary systems, (1-pentanol + ethylcyclohexane), (1-pentanol + methyl myristate), and (ethylcyclohexane + methyl myristate) were determined at different temperatures from 293.15 to 323.15 K. The experimental data were further employed to calculate excess molar volume ( V m E ) and viscosity deviation (Δ η ). Over the whole composition range, the V m E values show positive deviations from ideal behavior and the Δ η values are negative. The V m E values for the ternary mixtures were also correlated with the corresponding binary data using Cibulka and Redlich–Kister equations, respectively. The experimental data and results provide useful base data for further thermodynamic studies of alcohol–biodiesel–diesel blends.

Background Fe 2+ /H 2 O 2 -based photo-Fenton process is often used in pollutions removal. But, Fe-species related low activity at neutral condition hinders their practical applications. Activation of in situ generated H 2 O 2 for Fenton-like degradation of pollutions through catalysts absences of Fe species is expected. Methods A strip-like benzene and K + co-doped g-C 3 N 4 (KBCN) was constructed by the thermal polymerization of assembly of melamine and 2-aminoterephthalic acid, then post-calcination in LiCl–KCl molten salt, which was then used to degrade Rhodamine B (RhB) and Congo red (CR) via in situ generated H 2 O 2 . Significant findings Benzene and K + co-doping were critical both in increasing charge separation and enhancing the H 2 O 2 production. The yield of H 2 O 2 for KBCN was 57.5 μM in pure water after 60 min irradiation. In the absence of Fe 2+ , the in situ generated H 2 O 2 could subsequently degrade RhB and CR with the formed ·OH. The apparent rate constants of KBCN for RhB and CR degradation were 0.0446 and 0.0497 min −1 , respectively. The advantages of degradation with in situ generated H 2 O 2 in the absence of Fe 2+ can provide a new prospective to the environmental friendly Fenton-like reaction.

The dimensional reduction theory is applied to an A2O–P2O5–Bi2O3 system where P2O5 serves as a binary parent while A2O and Bi2O3 are regarded as dimensional reduction agents. Thus, three novel phosphates ACs5Bi4(PO4)2(P2O7)3 (A = K, Rb and Cs) have been prepared through the high-temperature solution method. Single-crystal X-ray diffraction measurements reveal that they all crystallize in the monoclinic space group P21/c (no. 14) and in their structures, two different kinds of P–O units, i.e. isolated PO4 tetrahedra and P2O7 dimers, are interconnected by Bi–O groups to construct a 3∞[Bi4(PO4)2(P2O7)36−] framework. Note that with the change of cationic size in their structures, the Bi3+ cations also exhibit flexible coordination, i.e. BiO5 and BiO6 polyhedra in KCs5Bi4(PO4)2(P2O7)3 and only BiO6 polyhedra in Cs6Bi4(PO4)2(P2O7)3, suggesting that combining the flexible coordination of Bi3+ cations with phosphates based on dimensional reduction theory is an effective strategy to guide the synthesis of new compounds.
