Dissolved organic matter (DOM) leaching from biodegradable microplastics (BMPs) and its characteristics and corresponding environmental implication are rarely investigated. In this study, the main component of DOM leachate from the two BMPs (polyadipate/butylene terephthalate (PBAT)/polycaprolactone (PCL)) was verified by using excitation-emission matrix-parallel factor analysis (EEM-PARAFAC). The PBAT-DOM (PBOM) was aromatized and terrestrial. Comparatively, PCL-DOM (PLOM) had low molecular weight . PBOM contained protein-like components while PLOM contained tryptophan and tyrosine components. Interestingly, both PBOM and PLOM could accelerate the decomposition and oxidation of coexisting polystyrene (PS) under light irradiation. Further, the difference in composition and the properties of BMPs-DOM significantly affected its photochemical activity. The high territoriality and protein-like component of PBOM significantly promoted the generation of 1 O 2 and O 2 •- , which caused faster disruptions to the backbone of PS. Simultaneously, the microbial community's richness, diversity, and metabolism were obviously improved under the combined pressure of aged PS and BMPs-DOM. This study threw light on the overlooked contribution of DOM derived from BMPs in the aging process of NMPs and their impact on the microbial community and provided a promising strategy for better understanding of combined MPs' fate and environmental risk.

The fabrication of patterned metal films is essential for a wide range of applications. Here, a novel solution-processing method is presented to achieve the area-selective deposition of copper on aluminum substrates via an in situ Al/CuSO 4 /Graphite voltaic cell template. And the copper ions preferentially deposit in the graphite-covered area due to the formed latent image of the potential difference between the graphite-covered area and the blank area on the aluminum surface. Benefiting from the low adhesive force of graphite, the formed copper layer can be easily peeled off and transferred to a flexible substrate to obtain the patterned conductive metal films. By studying the electrochemical properties of different surfaces and the in situ microscopic observation, four stages of electroplating process are proposed. More importantly, a positive correlation between the deposition speed and graphite coverage density is confirmed. This further enables a regional control of deposition thickness in addition to area-selective deposition, which means a 3D controllable metal deposition. Other forms of electroactive carbon are also demonstrated to replace graphite in this method, which offers a versatile and accessible technique to fabricate large-area flexible patterned metal films with defined feature size and controlled resolution from microscale to macroscale.

Copper-based metal halide scintillators have received increasing attention due to their high light yield and nontoxicity. However, the synthetic methods are still not feasible for actual commercialization for the difficulty in scaling up and the absence of green chemical footprint. Herein, we report a new, simple, aqueous synthetic method for the mass production of highly purified and crystallized Cs 3 Cu 2 Cl 5 powder by a room-temperature reaction between a saturated aqueous solution of CsCl and a saturated hydrochloric acid solution of CuCl. The product exhibits a photoluminence peak centering at 527 nm (FWHM = 106.7 nm) and a quantum yield (PLQY) of 97%. A prototype X-ray imaging detector is fabricated by coupling a large area scintillation screen prepared by blade coating of Cs 3 Cu 2 Cl 5 powder and a commercial thin-film transistor (TFT) panel (16 cm × 13 cm, 125 µm pixel size) with readout circuit. The device exhibits a high spatial resolution of 4 lp mm −1 , exceeding the theoretical limit of the TFT panel, and an excellent dynamic imaging ability. In short, this work demonstrates an efficient novel synthetic method of Cs 3 Cu 2 Cl 5 and its application as X-ray imaging device, providing an applicable solution for its future commercialization.

A blue thermochromic dye (B-TD) was prepared by mixing crystal violet lactone (CVL), hydroxyethyl acrylate (HEA) and myristic acid myristyl ester (MME). B-TD is a phase-changing material and can change colour at above 32°C about 5 s. The B-TD can permeate into pre-treated pinewood samples about 8–10 mm from the surface of samples after immersed pre-treated pinewood samples in B-TD for about 10 min at 70 °C. A blue thermochromic pinewood (B-TP) was prepared by filled the B-TD into pre-treated pinewood and covered polypropylene wax that can prevent B-TD overflowing from wood-based material when at phase-changing temperature. The B-TP can change colour from dark blue to light blue at 38–48°C, and can recover dark blue at below 38°C after about 5 h. B-TP can be used in a kind of pinewood woodwork that can indicate the temperature of woodwork surface to users by its colour-change phenomenon at 38–48°C, covering the lowest temperature of cryogenic burns (42°C), so this kind of pinewood woodwork can warn the temperature of cryogenic burns for avoiding cryogenic burns by its colour-change phenomenon.

Electrochromic materials cycle between colored and bleached states under various applied voltage and have applications in smart windows and displays. The formation of a micro–nano structure in electrochromic thin films using hydrothermal methods can improve their properties. However, the conventional constant-temperature hydrothermal method yields films that easily peel from the conductive substrate during electrochromic cycling, resulting in performance losses. Therefore, we investigated the effect of a gradient-temperature hydrothermal protocol on the electrochromic performance of NiO thin films. First, a layer of small, strongly adhered crystal grains was seeded on an indium tin oxide substrate. Thereafter, NiO nanoflake layers were grown by adjusting the reaction temperature. The prepared film could be operated for 14,000 electrochromic cycles, four-times more than those of the conventionally prepared films, without significant performance loss. Therefore, our proposed method enhances the cyclic stability of micro–nanostructured NiO thin films significantly and will aid the development of high-performance electrochromic thin films having broad applications.

A clinical therapy for chronic neuropathic pain is urgently needed, and the voltage-gated calcium channel (VGCC) α2δ subunit is among the most promising therapeutic targets. To intensively explore the structure-activity relationship (SAR) of the lipophilic moiety in VGCC α2δ subunit ligands (gabapentinoids), we designed and synthesized 11 bicyclic and monocyclic derivatives based on mirogabalin, a third-generation VGCC α2δ subunit ligand. The competitive binding of the synthesized compounds to the human VGCC α2δ-1 subunit was measured in vitro, and the results demonstrated that the lipophilic moiety size was strictly limited in gabapentinoids, in which conformationally rigid bicylo[3.2.0]heptane/heptene with a cis -fusion was the most preferred structure. In contrast, monocyclic cyclobutane was associated with a markedly decreased binding affinity except in 4 (IC 50 = 15.2 nM), in which the substituents could mimic the rigid conformation of bicylo[3.2.0]heptane/heptene; heteroatoms in the lipophilic moiety were detrimental to the binding affinity ( 2 , IC 50 > 729 nM). The SAR findings obtained in the present study will be valuable for designing novel gabapentinoid drugs to treat chronic neuropathic pain in the future. Graphical abstract

Water system zinc ion batteries (ZIBs) displays the attractive advantages and it has been considered as the main energy storage device to replace lithium ion batteries (LIBs). Unfortunately, the existing cathode materials are far from achieving the excellent performance required by increasing energy consumption. In recent years, the popular MoS 2 materials still suffer from the inherent defects of poor electrical conductivity, unstable structure, and large volume expansion and lamellar stacking during charging and discharging, resulting in weak periodic stability and severely hindering its commercial applications. In view of the special requirements of cathode materials for ZIBs, this work innovatively proposes the construction of new-type ternary composite nanomaterials, comprehensively improve the practicability of MoS 2 materials. The experimental results confirm that the prepared MoS 2 @WS 2 @CC composite material has high specific capacity and excellent rate performance, due to the synergistic effect of conductive carbon fiber substrate and large layer spacing WS 2 which can improve the volume expansion and diffusion rate fundamentally. Therefore, we can predict that the MoS 2 @WS 2 @CC composite is expected to accelerate the commercial application of ZIBs, and provide ideas for the design of other energy storage materials.

Biomorphic porous La 0.8 Ce 0.2 Fe 0.3 Co 0.7 O 3 perovskite-type catalysts are synthesized through a facile bio-templating method taking wood fiber as template for achieving the four-way purification of PM, NO x , CO, and HC emitted by automobile exhausts. The catalyst samples were characterized by X-ray diffractometer, Fourier-transform infrared spectroscopy, scanning electron microscope and Brunauer–Emmett–Teller analysis. The results showed that catalyst sample calcined at 700°C obtained high purity, high surface area (4.01 m 2 /g), wide pore size distribution and retained the initial wood fiber structure, which was suitable for purifying automobile exhausts. In addition, the performances for four-way purification under the simulated exhaust were analyzed by simulation test bench. The highest purification efficiency of PM, NO x , HC, and CO can reach 92%, 92%, 98%, and 76%, separately. Moreover, four-way purification mechanism was deduced according to the theoretical research of Mars-van krevelen on the redox reaction mechanism and experimental result.

Constructing faradaic electrode with superior desalination performance is important for expanding the applications of capacitive deionization (CDI). Herein, a simple one-step alkalized treatment for in situ synthesis of 1D TiO 2 nanowires on the surface of 2D Ti 3 C 2 nanosheets, forming a Ti 3 C 2 -MXene partially derived hierarchical 1D/2D TiO 2 /Ti 3 C 2 heterostructure as the cathode electrode is reported. Cross-linked TiO 2 nanowires on the surface help avoid layer stacking while acting as the protective layer against contact of internal Ti 3 C 2 with dissolved oxygen in water. The inner Ti 3 C 2 MXene nanosheets cross over the TiO 2 nanowires can provide abundant active adsorption sites and short ion/electron diffusion pathways. . Density functional theory calculations demonstrated that Ti 3 C 2 can consecutively inject electrons into TiO 2 , indicating the high electrochemical activity of the TiO 2 /Ti 3 C 2 . Benefiting from the 1D/2D hierarchical structure and synergistic effect of TiO 2 and Ti 3 C 2 , TiO 2 /Ti 3 C 2 heterostructure presents a favorable hybrid CDI performance, with a superior desalination capacity (75.62 mg g −1 ), fast salt adsorption rate (1.3 mg g −1 min −1 ), and satisfactory cycling stability, which is better than that of most published MXene-based electrodes. This study provides a feasible partial derivative strategy for construction of a hierarchical 1D/2D heterostructure to overcome the restrictions of 2D MXene nanosheets in CDI.

Biomimetic mineralization of high-strength apatite structure essentially relies on mimicking the inorganic building blocks of naturally occurring bones. However, conventional routes still have substantial function gaps in providing precision control over the geometrical dimensions and crystalline morphology of biomineralized apatite. Herein, we conceived the concept of microwave-assisted biomineralization (MAB) to customize 1D hydroxyapatite nanowhiskers (HANWs) at graphene templates, rendering the formation of graphene-hydroxyapatite (Gr-HA) nanohybrids. The HANWs essentially resembled bone apatite in elemental composition (Ca/P = 1.74), diameter (~20 nm), crystallinity (63 %), and rodlike geometry (aspect ratio of ~6). The Gr-HA nanohybrids were uniformly incorporated into poly(lactic acid) (PLA) microfibers (~1 μm) by electrospinning, engendering fibrous membranes with a set of Gr-HA loadings (10, 20 and 30 wt%). Intimate interactions were generated between Gr-HA and PLA matrix, contributing to significant promotion of the mechanical properties for PLA composite membranes. For example, the yield strength and elastic modulus of the PLA composite membranes loaded with 30 wt% Gr-HA achieved 5.4 and 66.4 MPa, increasing nearly 182 % and over 94 % compared to those of pure PLA, respectively. Moreover, the bone-like HANWs endowed PLA membranes with excellent cytocompatibility and good bioactivity, as demonstrated by over 38 % increase in cell viability and rapid apatite formation in mineral solution. The impressive combination of mechanical properties and biological characteristics make the PLA/Gr-HA scaffolds promising for guided tissue/bone regeneration therapy.

Oil–water separation using porous superhydrophilic materials is a promising method to circumvent the issue of oil-polluted water by separating water from oil–water mixtures. However, fabricating metal-based porous superhydrophilic materials with stable superhydrophilicity that can recover their strong hydrophilicity and have acceptable oil–water separation efficiency without complex external stimuli is still a challenge. Inspired by the anti-wetting behavior of broccoli buds, this study successfully fabricated metal-based superhydrophilic and underwater superoleophobic porous materials by hydrothermal treatment of stainless steel meshes (SSMs) combined with magnetron sputtering of metallic Ti and W. The process was then followed with annealing at 300 °C for 4 hours. The effects of coating materials, annealing temperature, and surface structure on the wetting behavior of the prepared meshes were studied and analyzed. The modified meshes exhibited unique broccoli-like microstructures coated with thin TiO2−xNx/WO3 films and showed superhydrophilicity with a 0° water contact angle (WCA) and underwater superoleophobicity with underwater oil contact angles (UOCAs) higher than 155°. They also maintained strong hydrophilicity for more than three weeks with WCAs of less than 13°. Besides, they could recover their initial superhydrophilicity with a 0° WCA after post-annealing at 80 °C for 30 minutes. Notably, the broccoli-like structures and the strong hydrophilic coatings contributed to a significant water flow rate (Q) of 3650 L m−2 h−1 and satisfactory oil–water separation efficiency of 98% for more than 15 separation cycles toward various oil–water mixtures. We believe that the presented method and fabricated material are promising and can be applied to induce hydrophilicity of various metallic materials for practical applications of oil–water separation, anti-fouling, microfluidic transport, and water harvesting.

The developments of high-resolution mass spectrometry and soft ionization technologies have enabled the molecular characterization of petroleum fractions. However, quantitative analysis of molecular composition for petroleum is far from being achieved. In this study, semi-quantitative analysis of molecular composition for the whole compounds in heavy petroleum fractions was carried out. Hydrocarbons and various heteroatoms in the heavy petroleum fractions were characterized by only electrospray ionization coupled with high-resolution mass spectrometry. The molecular composition of various types of compounds were calculated and integrated quantitatively based on bulk chemical composition. The semi-quantitative molecular compositions of four heavy petroleum fractions with largely different bulk properties were comprehensively characterized in multiple dimensions such as carbon number distribution, condensation degree, molecular weight, mass fraction, and molecule number. More than 5,000 molecules, which classified into 16 compound classes of seven groups were quantitatively characterized from the four fractions. The accuracy of the analysis seems acceptable according the H/C ratio comparation between that derived from element analysis and the semi-quantitative molecular composition. Representative molecule set containing structural information was also proposed based on the semi-quantitative results.
