A commonly used strategy to tackle the unstable interfacial problem between Li1.3Al0.3Ti1.7(PO4)3 (LATP) and lithium (Li) is to introduce an interlayer. However, this strategy has a limited effect on stabilizing LATP during long-term cycling or under high current density, which is due in part to the negative impact of its internal defects (e.g., gaps between grains (GBs)) that are usually neglected. Here, control experiments and theoretical calculations show clearly that the GBs of LATP have higher electronic conductivity, which significantly accelerates its side reactions with Li. Thus, a simple LiCl solution immersion method is demonstrated to modify the GBs and their electronic states, thereby stabilizing LATP. In addition to LiCl filling, composite solid polymer electrolyte (CSPE) interlayering is concurrently introduced at the Li/LATP interface to realize the internal–external dual modifications for LATP. As a result, electron leakage in LATP can be strictly inhibited from its interior (by LiCl) and exterior (by CSPE), and such dual modifications can well protect the Li/LATP interface from side reactions and Li dendrite penetration. Notably, thus-modified Li symmetrical cells can achieve ultrastable cycling for more than 3500 h at 0.4 mA cm–2 and 1500 h at 0.6 mA cm–2, among the best cycling performance to date.

Information regarding relevant solid–liquid balance pertaining to 3-nitro-1 H -pyrazole (3-NP) within a range of solvents is of a high significance to the preliminary analysis of industry-related uses. Here, through the gravimetric approach, 3-NP dissolvability in various clean solvents, i.e., n -butyl acetate (NBAC), isopropyl acetate (IPAC), n -propyl acetate (NPAC), ethyl acetate (EAC), methyl acetate (MAC), n -propanol (Pro-OH), ethanol (EtOH), methanol (MeOH), toluene (PhMe), acetonitrile (AN), tetrahydrofuran (THF), acetone (DMK), water and benzene (Ph), was explored under an atmosphere pressure of 0.1 MPa and within a range of temperature ( T = 283.15 K to 323.15 K). In accordance with the outcomes, with the rise of the temperature, 3-NP dissolvability increased in fourteen solvents taken. Among all the solvents, water exhibiting the maximum polarity had the minimum dissolvability, while methanol exhibited the maximum quality of solubility. At a particular temperature, 3-NP’s quality of solubility followed that of MeOH (8.54 × 10 -2 , 323.15 K) > EtOH (6.46 × 10 -2 , 323.15 K) > Pro-OH (6.27 × 10 -2 , 323.15 K) > AN (4.18 × 10 -2 , 323.15 K) > DMK (3.76 × 10 -2 , 323.15 K) > MAC (3.20 × 10 -2 , 323.15 K) > EAC (2.82 × 10 -2 , 323.15 K) > NPAC (2.25 × 10 -2 , 323.15 K) > NBAC (1.91 × 10 -2 , 323.15 K) > IPAC (1.25 × 10 -2 , 323.15 K) > THF (1.07 × 10 -2 , 323.15 K) > PhMe (7.29 × 10 -3 , 323.15 K) > Ph (3.23 × 10 -3 , 323.15 K) > water (2.16 × 10 -3 , 323.15 K). The experimental data of 3-NP had a correlation according to Wilson approach, NRTL model, λh equation and the modified Apelblat equation. As was revealed from the fitting outcomes, the optimal correlative result of the experimental information was given through NRTL model. The relative average deviation (10 2 ARD) and the root-mean-square deviation (10 4 RMSD) achieved were lower than 9.44 and 23.75 separately. Moreover, 3-NP dissolvability characteristics in solvents studied were analyzed with the use of the Hansen dissolvability coefficient ( δ d , δ p , δ h , δ t , and Δ δ t ) here. This study determined the effect exerted by interacting processes pertaining to solvent–solute and solvent–solvent molecules upon the 3-NP’s quality of solubility with the association of linear solving energy in accordance with the descriptors of the solvents. Moreover, the mixing characteristics of 3-NP in 14 pure solvents, including the mixing Gibbs energy ( Δ mix G ), mixing enthalpy ( Δ mix H ) and mixing entropy ( Δ mix S ), were determined and analyzed through Wilson approach. The result of Δ mix G < 0 indicated that the dissolution pertaining to 3-NP in the solvents taken was spontaneous. The data pertaining to lnγ 1 ∞ and lnγ 1 was similar, demonstrating that 3-NP in the solution mechanisms of solvents taken was not highly non-ideal. The results presented conducive data in terms of actual 3-NP crystallization optimizing procedure.

To improve the understanding on methane storage in wet porous media under hydrate favorable conditions, hydrate formation loaded by an activated carbon bed in three three-dimensional printed containers was carried out, while the recycling performance of the activated carbon bed was also evaluated. As expected, due to low permeability of the bed, poor hydrate kinetics was observed for small particles, but this is improved by increasing the exposure of the bed. When there is hydrate formation loaded by an activated carbon bed in a container, the specific contact area governs hydrate nucleation and growth kinetics, and the accessibility of methane with inner water increases with the increase in gas–solid contact area, giving rise to fast hydrate nucleation and large methane uptake. Impressively, the hydrate induction time for container 3 is only 3.53 and 41.79% of that in container 1 under the filling ratios (volume ratio of the sample to container) of 80 and 100% separately, while the methane uptake increases by about 8% for both the scenarios. In addition, because of the migration of water to side walls, exceptional recycling performance of the activated carbon bed was also observed, and this characteristic causes the bed to be easily charged and discharged like a battery. These findings may pave the way for the application of the adsorbed natural gas technology using wet activated carbon under hydrate-favorable conditions.

Janus evaporators achieve an energy utilization efficiency of 97.88%. • Janus evaporators demonstrate evaporation rates of 4.31 kg·m −2 ·h −1 . • Janus evaporators exhibit excellent long-term stability for 12 days. • Janus evaporators produce 18.53 kg·m −2 of fresh water per day. Solar interfacial evaporation is an emerging sustainable freshwater production technology. However, its effectiveness is often hindered by insufficient heat and mass transfer, the inherently high enthalpy of vaporization of water, and salt management issues. This study proposes a Janus-type photothermal semiconductor@biomass porous hydrogel evaporator to achieve high-rate and highly energy-efficient solar interfacial evaporation. Efficient biomass-based water transport channels were constructed through a microphase separation process and in-situ ionic crosslinking. The hydrophilic microenvironment of polar polymers was utilized to regulate the aggregation state of water molecules and reduce the equivalent enthalpy of vaporization. The Janus evaporator was assembled from photothermal semiconductors (tellurium nanoparticles) and biomass porous hydrogels to synergistically improve evaporation efficiency. Under one sun illumination, the evaporator achieved evaporation rates of 4.31 kg·m −2 ·h −1 in deionized water and 3.10 kg·m −2 ·h −1 in 3.5% simulated seawater, with an energy efficiency of 97.88%. Furthermore, due to the salt diffusion facilitated by the porous structure, it exhibited stable salt tolerance in simulated seawater with a high salinity of 10%. Outdoor natural seawater desalination experiments further confirmed its water production capacity and long-term stability, and the desalinated water quality met drinking water standards. This work provides a novel and forward-looking strategy for designing environmentally friendly, efficient, and stable solar evaporators.

How to improve the solubility of linear dextrins (LD) and retain their characteristic helix amphiphilic cavities with flexible embedding capability, is a question worth exploring without adding new chemical groups. The strategy presented in this study is to attach a highly flexible (α-1 → 6) glucochain at the reducing end of LD by preparing a new type of dextrin, referred to as single-arm linear dextrin (SLD). In the actual synthesis, an (α-1 → 6) linked oligosaccharide of DP ¯ 10.7 (PDI = 1.28) was formed by extension of glucose units onto sucrose (2 M) by using L940W mutant of the glucansucrase GTF180-ΔN firstly. Next using γ-CD as glucosylation donor γ-CGTase extended this (α-1 → 6) glucochain with (α-1 → 4) bonds. SLD is a chimeric glucosaccharide comprising an (α-1 → 4) linked part ( DP ¯ 10.5) attached to the nonreducing end of an (α-1 → 6) glucochain as verified by enzyme fingerprinting and 1 H NMR. Furthermore, SLD was validated to show greatly improved solubility and dispersibility of resveratrol in water, as indicated by a 3.12-fold enhancement over the solubility in the presence of 0.014 M SLD. This study provided a new strategy for solving the solubility problem of LD and opens possibilities for new design of the fine structure of starch-like materials.

This work reported an air atmospheric pressure plasma jet served as an ion source for nonvolatile solid analysis, which allows a unique capability to achieve thermal desorption and ionization simultaneously without complex devices, inert gas, or solvents. Owing to precise amount of heat generated by plasma jet, nonvolatile analytes were thermally released from solid surfaces without the assistance of secondary desorption equipment. According to the mass spectra and Fourier transform infrared spectrum, [M + H]+ and [M + NO3]− ions were the major analyte ions in the positive-ion and negative-ion modes, respectively. The applied voltages, discharge currents, and gas temperatures of plasma jet were measured, and found to be positively correlated with the mass spectra signal intensity of the samples, while the added resistances and gas flow rate were negatively correlated with the signal intensity. The influence mechanisms of analytes natures coupling physical parameters of plasma jet on detection performance were revealed. The prospect of quantitative testing was confirmed by the linear relationship between the peak intensity and sample mass.

The preparation of an organic polymer monolithic column modified with an amino acid ionic liquid and graphene oxide (AAIL-GO) and its application to capillary electrochromatography (CEC) was described. The AAIL tetramethylammonium-L-arginine was bonded to a monolithic column that was previously modified with graphene oxide by using an hydrochloride/N-hydroxysuccinimide coupling reaction. The morphology of a poly(glycidyl methacrylate-co-ethylene dimethacrylate) monolith was examined by scanning electron microscopy. The incorporation of AAIL and graphene oxide was detected by infrared spectroscopy and elemental analysis. The resulting monolithic column produced a strong and stable electroosmotic flow from the anode to the cathode in the pH range from 3 to 9. Compared with a column modified with AAIL or graphene oxide only, the AAIL-GO-modified column has a better separation ability for amino acids, β-blockers, and nucleotides (the resolution of three amino acids: 2.231 and 2.036, β-blockers: 2.779 and 2.470 and nucleotides: 8.345 and 3.321). Molecular modeling was applied to demonstrate the separation mechanism of small molecules which showed a good support for experimental results.

Four new monoiron (II) tricarbonyl complexes with the amine bound, fac -[Fe(CO) 3 I 2 (NH 2 R)] (R = Et, 1 ; n Pr, 2 ; n Bu, 3 ; n Pent, 4 ), were reported using cis -[Fe(CO) 4 I 2 ] as the precursor. All the complexes 1 – 4 were structurally confirmed by various techniques such as ultraviolet–visible (UV–vis), Fourier transform infrared (FTIR), and nuclear magnetic resonance (NMR) spectra and elemental analysis of which complexes 1 and 2 are crystallographically determined. The reaction of the precursor with alkylamines proceeded in two main parallel pathways to form both aminium salts of fac -[Fe(CO) 3 I 3 ] − and the amine-bound complexes ( 1 – 4 ). Their dominances altered with the reaction time. These complexes in DMSO undergo quick decomposition with complex 1 as the relatively most stable one ( t 1/2 = 7.3 min) although they are stable in solid status. Unlike the triiodo anion and pyridinyl analogs showing severe cytotoxicity due to the generation of iodine radical during the decomposition, no iodine radicals were detected from the fac -[Fe(CO) 3 I 2 (NH 2 R)] complexes. Therefore, the cell viability of RT112 cells was not affected by the presence of the amine-bound iron complex ( 1 ) up to 100 μmol L −1 .

Nowadays, the Chlorination-Hercosett process dominates the production of machine-washable wool fabric. However, absorbable organic halogens (AOX) generated during the treatment are highly detrimental to human health and the environment. Herein, we developed an innovative pad-steam-pad-cold batch enzymatic treatment with the merit of being eco-friendly, water-saving, and cost-effective to replace traditional high pollution chlorination technique. With the assistance of sodium sulfite or L-cysteine, a broad-temperature-range proteinase (BTRP) can efficiently hydrolyze wool scales during the steaming and cold batch processes. The results indicate that BTRP treatment endows the wool fabric with excellent dimensional stability, acceptable strength loss, and improved wearability properties such as drapability, and air and moisture permeability. This non-chlorination treatment achieves a felting shrinkage of 4.33 % ± 0.28 %, and a tensile strength loss of 12.36 % ± 1.46 %. Furthermore, colored wool samples treated with BTRP were shown to maintain their original color performance, including K/S value and various color fastness properties. Pilot plant tests indicates that this technique remarkably decreased the cost of chemical materials and water usage during enzymatic treatment. As an ideal alternative substitute for the Chlorination-Hercosett treatment, the “pad-steam-pad-cold batch” approach based on BTRP treatment can be utilized for commercial production of pristine and colored machine-washable wool garments.

The exploitation of high-performance anode materials is one of the key challenges for the development of lithium-ion batteries. Herein, we report a micro-nano structured (SnS–SnS2–S)/FLG (few-layer graphene) composite in which the in situ formed SnS, SnS2 and S nanoparticles are tightly supported by the in situ exfoliated FLG. The multi-phase structure could induce the formation of a high fraction of interfaces, enabling the interface-controlled lithiation/delithiation, which is characterized by large interfacial storage and fast interfacial diffusion, and boosting the electrode performance at high rates greatly. On the other hand, the step-wise lithiation/delithiation of S, SnS2 and SnS can offer nano-spatial confinement effects to accommodate the volume expansion and particle aggregation, and thus enhance the structural stability of the electrode. Meanwhile, the FLG matrix can serve as a robust layer to further maintain the structural integrity of the electrode. As an anode for lithium-ion batteries, the composite exhibits an ultrahigh gravimetric/volumetric capacity (1062.2 mA h g−1/2018 mA h cm−3 at 0.2 A g−1), ultrahigh rate (842/756 mA h g−1 even at 5.0/10.0 A g−1) and ultrastable cyclability (100%/93.6% capacity retention after 1000/2000 cycles at 1.0/10.0 A g−1). Even in full-cells and sodium-ion batteries, superb comprehensive performance is demonstrated. Therefore, the (SnS–SnS2–S)/FLG composite could be a new promising anode material for application in batteries.

Clothianidin are significant toxicity toward non-target organisms, underscoring the necessity for a simple and highly sensitive biosensor for on-site detection. Herein, a pH responsive biotin-tagged horseradish peroxidase (HRP)-encapsulated nanoliposome (HRP@liposome) was synthesized and applied to a colorimetric immunosensor as signal amplification generator. In the presence of clothianidin, it competes with coated antigens for binding to biotinylated antibodies, thereby reducing the number of HRP@liposome due to biotin-streptavidin-biotin interactions. Upon addition of substrate solution, the HRP@liposome are lysed, releasing a substantial amount of HRP, which catalyzes the oxidation of substrate. Under optimal conditions, the colorimetric immunosensor exhibited a 50 % inhibition concentration of 4.75 ng mL −1 , with a limit of detection of 0.24 ng mL −1 , and a linear range of 0.24–66.23 ng mL −1 , respectively. The average recoveries were 86.1 %–103.6 % in spiked environmental and food samples. Compared with conventional enzyme-linked immunosorbent assays, the proposed immunosensor demonstrates higher sensitivity. This research provides a promising reference for rapid assessment in environmental health and food safety.

The electrocatalytic nitrate reduction reaction (NO3RR) is promising for achieving the dual goals of sustainable ammonia production and wastewater remediation. Nevertheless, the highly selective ammonia (NH3) synthesis remains a formidable challenge, primarily attributed to the complex reaction pathway, instability of metal-based catalysts, and the competitive hydrogen evolution reaction (HER). Herein, we propose a novel electrocatalyst (TA–Fe/Co3O4) prepared via a metal–polyphenol assembly strategy integrating natural plant polyphenol (tannic acid, TA) and iron (Fe) molecular assembly. Active components are anchored and stably dispersed on TA, while Fe incorporation is conducive to accelerating reaction kinetics, synergistically enhancing the electrocatalytic efficiency of spinel Co3O4. The catalyst delivers a faradaic efficiency (FE) of up to 94.36% at −0.2 V vs. RHE and an exceptional NH3 yield rate of 206.50 μmol h−1 cm−2 (−0.5 V vs. RHE). This work presents a facile and economical route for designing efficient transition metal oxide catalysts for the reduction of nitrate to NH3.
