The high reactivity of Li-anodes and the easily separated solid-state interface are two hurdles for constructing stable solid-state Li-metal batteries (SSLBs). Herein, we report a 3D mixed ion–electron conductive (MIEC) Li anode with deformable molten interphase of poly(Ɛ-caprolactone) electrolytes that is highly efficient towards constructing stable SSLBs. The 3D Li anode is fabricated by integrating a Li foil with a MIEC film via a facile hot-rolling process, in which the MIEC frame is composed of Li 0.33 La 0.56 TiO 3 particle attached carbon nanofibers . We propose that the chemical reactions between Li 0.33 La 0.56 TiO 3 and Li facilitates Li-nucleation inside the MIEC frame and thus enables fast stress relaxation and reduces volume fluctuations, while the molten interphase works as a binder to integrate the anodes and electrolytes without delamination during cycling. As a result, the symmetrical batteries run stably for 1200 h at 45 ℃, and the 3D Li/LiFePO 4 full batteries achieve a capacity of 134 mA h g −1 at 1C with a high-capacity retention of 98 % after 250 cycles, showing appealing commercial prospect.

The western flower thrips (Frankliniella occidentalis) is a major pest insect in agriculture. However, few insecticides are effective for their control. The recombinant gamma-aminobutyric acid receptor-associated protein (rGABARAP) was examined as a potential target of the monoterpenoids responsible for their insecticidal activities. The insecticidal activity of anethole, linalool, and methyl eugenol (ME) was evaluated in the laboratory. The half-maximum lethal concentration (LC50) of ME against second-instar nymphs of F. occidentalis was 5.5 mg/L using membrane and leaf immersion methods, while that of spinosyn A was 1.0 mg/L. The dissociation constants of ME binding to rGABARAP were 1.30 and 4.22 μmol/L, respectively, according to microscale thermophoresis (MST) and isothermal titration calorimetry (ITC) measurements. A molecular docking study showed interactions between ME and Tyr174 via π–π stacking. The MST and ITC experiments showed loss of specific binding between ME and the rGABARAPY174A mutant. Therefore, Tyr174 is a key amino acid residue of rGABARAP involving ME binding. The results revealed GABARAP as a potential target for the development of monoterpenoid insecticides.

During the separation of water-insoluble oil droplets in the oily wastewater by the membrane treatment process, the simultaneous removal of organic pollutants dissolved in the aqueous phase remains a challenge. Herein, we demonstrate an effective strategy for preparing dual-functional membranes with hybridization of novel β-cyclodextrin (β-CD) derivatives to achieve complete cleansing of oily sewage. Alkylenedioxy bridged bis(p-difluoro-p-dicyano) phenyl substituted β-CDs (R 3 -2T-2β-CD and R 6 -2T-2β-CD) are first synthesized and incorporated into three frequently used membranes (polyethersulfone (PES), poly( p -phenylene terephthalamide) (PPTA) and poly( m -phenylene isophthalamide) (PMIA)) casting solutions to fabricate hybrid membranes, respectively. The hydrophilicity of the prepared membrane can be improved greatly for the separation of oil-in-water emulsions. The PMIA/R 3 -2T-2β-CD membrane exhibited pure water permeances over 760.50 L·m −2 ·h −1 ·bar −1 with separation efficiency of the tween 80 stabilized diesel-in-water emulsion above 98.62% under cross-flow filtration. Significantly, the hybrid membranes could concurrently remove naphthalene and methylene blue dissolved in water during oil-in-water separation. This study proves the application potential of cyclodextrins in designing membrane materials and these one-step hybrid membranes can thoroughly decontaminate oil-in-water emulsions by eliminating the dissolved polycyclic aromatic molecules.

In this study, a supersensitive electrochemical impedance spectroscopy (EIS) analysis method combined the molecularly imprinted polypyrrole (MIP) which electropolymerized on the composites of zirconium-based metal organic framework (Uio-66) and carbon dots (CDs) modified glassy carbon electrode (GCE) was developed for chloramphenicol (CAP) determination. The integration of Uio-66 and CDs effectively promoted the sensitivity of the proposed MIP senor by improving the surface area and the charge transfer of electrode. By extraction of CAP template, the specific sites were formed on the MIP surface which can rewrap the CAP target molecules. The CAP determination was based on the charge transfer difference (△Rct) before and after the MIP/ [email protected] /GCE rebinding the CAP. The results showed that △Rct responded good linearity to the logarithm of CAP concetration in the range of 0.1 – 100 pmol/L, with a low detection limit of 0.061 pmol/L (S/N = 3), exhibiting high sensitivity and specificity for the determination of CAP.

High mortality and rapid development of metastasis requires the development of more effective antimetastasis strategies. However, conventional therapeutic methods, including surgery, radiation therapy, and chemotherapy, show less effectiveness in curbing the metastatic spread of cancer cells and the formation of metastases. A therapeutic platform, targeting the early stage of metastasis cascade, could effectively prevent metastasis dissemination. Herein, Fe/Mn-based metal–organic frameworks (FMM) were constructed for the delivery of a specific DNAzyme with high catalytic cleavage activity on the metastasis-involved Twist mRNA, thus efficiently inhibiting the invasion of cancer cells through DNAzyme-catalyzed gene silencing. Highly potent combined gene/chemodynamic therapy is achieved from the self-supplied DNAzyme cofactors and efficient glutathione depletion. Importantly, by virtue of the intrinsic photo-to-thermal conversion of the FMM nanocarriers, our combined therapeutic strategy could be further promoted under photothermal stimuli to speed up the Fenton reaction and to accelerate the release of the Twist DNAzyme with efficient gene therapy. Consequently, the effective elimination of tumors and the blockage of metastasis are simultaneously achieved under photothermal/magnetic resonance imaging guidance. This work aims at developing versatile theranostic agents to combat metastatic tumors. Associated Products

Generally, superhydrophilic self-cleaning coatings are prepared from semiconductors with photocatalytic properties. Organic pollutants attached to the coating surface can be degraded by its photocatalytic performance realizing a self-cleaning goal. Herein, SiO 2 –TiO 2 composite particles were fabricated by the hydrolysis and precipitation of TiOSO 4 , and SiO 2 microspheres were chosen as carriers, which are inexpensive and environmentally friendly. Then, superhydrophilic self-cleaning SiO 2 –TiO 2 coatings were fabricated by spraying the composites on the surfaces of substrates. The morphology, structure and self-cleaning performance of the SiO 2 –TiO 2 coating were characterized and tested. The results revealed that nano-TiO 2 was loaded on the surfaces of SiO 2 microspheres uniformly forming a hierarchical micro/nanostructure. The SiO 2 –TiO 2 composite particles exhibited excellent photocatalytic degradation performance, and the degradation rate of methyl orange (10 ppm) was more than 98% under UV irradiation for 40 min. Furthermore, the coating prepared with the SiO 2 –TiO 2 composite particles exhibited superhydrophilicity. A water droplet spreads completely on the coating surface in 0.35 s, and the contact angle reaches 0°. In addition, rhodamine B (RhB) and methylene blue (MB) on the coating surface can be degraded efficiently under sunlight irradiation. The SiO 2 –TiO 2 composite particles can be sprayed directly on the surfaces of concrete, brick, wood, and glass slides. Therefore, the particles showed good adaptability to different substrates. The superhydrophilic property was due to the hydrophilicity of SiO 2 and TiO 2 , the hierarchical micro/nanostructure of the SiO 2 –TiO 2 composites, and the photoinduced superhydrophilicity of TiO 2 . The above experimental results show that the as-prepared superhydrophilic self-cleaning SiO 2 –TiO 2 coating has a large application potential. Associated Products

A series of deep-eutectic solvents (DESs) with potassium hydroxide as hydrogen bonding acceptor and monoethanolamine (MEA) or polyethylene glycol (PEG) as hydrogen bonding donor were prepared and used as catalyst for the synthesis of glycidol and glycerol carbonate from glycerol and dimethyl carbonate. The effect of reaction parameter (reaction temperature, dimethyl carbonate/glycerol molar ratio, catalyst amount and reaction time) on the reaction was investigated in detail. It is found that the activity of KOH:MEA DES catalyst is related with its basicity. The KOH:MEA(1:2) exhibits higher catalytic activity, which may be due to the strong hydrogen bonding action between KOH:MEA(1:2) and reactants. The reaction kinetics model is also established and the reaction rate constant and active energy for each reaction are obtained by fitting the experimental data. The component concentration calculated by the kinetics model is close to the one of the experimental value. Associated Products

The physicochemical properties and interactions of the complex of oleic acid (OA) and β-cyclodextrin (β-CD) were studied by experimental and computational methods. Differential scanning calorimetry and X-ray diffraction confirmed the successful preparation of OA/β-CD inclusion complex. The stability of the complex was improved, exhibiting a 61.2 °C higher degradation temperature and a lower peroxide value than OA. Raman and Fourier transform infrared spectroscopy studies revealed that the carboxyl group of OA entered into the β-CD cavity to form hydrogen bonds, which was confirmed by conformational search and weak interactions analysis. Dispersion energy from van der Waals (–290.79 kJ/mol) contributed 87.3% to total interaction energy (–253.88 kJ/mol). Topological analysis showed that four moderate hydrogen bonds were formed between OA and β-CD with the bond energy ranging from –76.05 to –30.25 kJ/mol. This work provided theoretical basis for the development of nutritional supplements containing unsaturated fatty acids encapsulated by β-CD. Associated Products

Layered double hydroxide (LDH) bearing numerous hydroxyl groups shows high affinity with CO 2 and is promising in mixed matrix membranes (MMMs) based CO 2 capture. However, its non-porous structure limits the further improvement of CO 2 permeability. In this work, 3D hollow CoNi-LDH nanocages were developed to construct low-resistance and CO 2 -philic transport channel in MMM by in-situ etching of ZIF-67 template. The resultant material exhibits hollow structure with cavity size of about 500 nm, mesopores and micropores from LDH stacking and ZIF-67 template. The outer layered CoNi-LDH nanosheets can attract more CO 2 molecules by their abundant hydroxyl groups, resulting in an improvement in dissolution selectivity of CO 2 over N 2 . Meanwhile, the tortuous gas diffusion paths originated from 2D nanosheet stacking can further enhance the CO 2 selectivity over N 2 . Moreover, the hollow nanocages provide CO 2 molecules with fast transport path, resulting in high CO 2 permeability. As a result, compared with pure Pebax membrane and 2D LDH/Pebax MMM, all the 3D hollow CoNi-LDH/Pebax MMMs present enhanced CO 2 permeability. The 3D hollow CoNi-LDH-2h/Pebax MMM performs the highest CO 2 permeability of 135.49 Barrer, which are increased by 141.95% and 71.50% than those of the above two membranes, respectively. The selectivity of 3D hollow CoNi-LDH-2h/Pebax MMM is about 26.30% higher than that of the pure Pebax membrane. The present membrane presents comparable CO 2 capture capacity in contrast with most reported Pebax based MMMs and surpasses the Robeson upper bond. Together with the good long-term stability, the 3D hollow CoNi-LDH nanocages are believed to be a promising candidate for MMMs to improve CO 2 capture. Associated Products

The sluggish oxidation kinetics of ferrate (Fe(VI)) at neutral and slightly alkaline pH impedes its rapid abatement of micropollutants in practical application. This work discovers that graphite (GP), a metal-free carbonaceous material , can be a promising material to improve the reactivity of Fe(VI) in the pH range of 7.0 − 9.0. The performance of the GP/Fe(VI) process for sulfamethoxazole (SMX) removal was further evaluated via altering the dosages of Fe(VI), GP, and SMX. Probe analysis and quenching experiments identified Fe(IV) and Fe(V) as the primary active species responsible for the removal of organic compounds in the GP/Fe(VI) system. The detailed activation mechanism of GP is discussed via analyzing the surface chemical changes of GP exposed to Fe(VI). It is found that the carbonyl groups on GP surface execute a critical role in Fe(VI) activation. The GP/Fe(VI) system shows powerful anti-interference ability to environmental background substances. Therefore, the new oxidation process proposed in this work holds a great application prospect for contamination remediation. Finally, we discuss the underlying degradation pathways of SMX by the GP/Fe(VI) system. This study not only develops a promising system for the removal of micropollutants but also provides an in-depth insight into the activation mechanism of metal-free carbonaceous material in Fe(VI) oxidation process.

In this work, a surprisingly simple and versatile strategy was developed to construct organic/inorganic bi-layer coating, and excellent lubricating properties and long service life are achieved simultaneously. The PTFE/Al 3+ -MXene coating was fabricated by a two-step strategy including self-assembly of Al 3+ -induced MXene coatings and in-situ transfer of PTFE under the induction of friction force and heat, which are designed to promote the molecular interaction and mechanical properties of composite coating, respectively. The ratio of Al 3+ /MXene concentration and pre-friction time against PTFE ball were regulated and optimized. It was found that the interaction exists between the transferred PTFE layer and MXene layer. Molecular dynamics simulations confirmed that the PTFE molecular chains could be anchored at the oxidation site of MXene sheets through friction-induced molecular welding, slowing MXene’s oxidation diffusion from the edge to the surface. The research results show that PTFE/Al 3+ -MXene coating after 1.0 h of pre-friction time presents the best service life among the prepared coatings, approximately 9 times longer than the PTFE transfer layer-1.0 h, and also much better than the Al 3+ -MXene 10 raw coating without transferring PTFE. It was further found that the obtained PTFE/Al 3+ -MXene/T-1.0 composite coating facilitates the easy formation of secondary transfer film on the upper counterpart, which is critical in extending the wear-resisting life of PTFE/Al 3+ -MXene/T-1.0 bi-layer coating.

Ionic conductors have promising applications in the field of flexible electronics, but they usually suffer from weak bonding to substrates (<0.3 MPa), leading to large interfacial impedances or detachment under repeated deformation. Here, a supramolecular deep eutectic polymer synthesized by in situ photopolymerization of a polymerizable deep eutectic solvent monomer is proposed as a self-adhesive dry ionic conductor (SADIC). The SADICs obtained are rich in dynamic hydrogen bonding and ions, which can instantly form various interfacial interactions and firmly adhere to substrates and maintain good mechanical robustness. Notably, the maximum adhesion strength is up to ∼3.5 MPa (on indium tin oxide (ITO) glass). Furthermore, the SADICs also show other comprehensive properties such as high transparency, tunable stretchability, favorable conductivity, and excellent mechanical and electrical self-healing capabilities. As a demonstration, the SADIC can be used as a durably self-adhesive ionic skin for volume change and deformation monitoring. These findings provide a promising strategy for improving device integration and enhancing the performance of flexible electronics. Associated Products
