Histamine (HA) is an essential test item for fishery samples. However, the fast and effective determination of HA is difficult due to its simple structure and small molecular size. In this study, a sensitive and specific monoclonal antibody against p-nitrobenzoylated histamine (NPHA), which can be easily obtained from the reaction of HA and p-nitrobenzoic acid N-hydroxysuccinimide ester (PNBA-OSu) under mild conditions, was generated for the first time. Based on this mAb, an immunochromato-graphic assay strip (ICA strip) using a colloidal gold nano particles-antibody (GNPs) probe for rapid detection of HA in saury samples was established. After screening the coating antigens and optimization of analytical parameters, a heterologous coating based ICA strip exhibited the most excellent detection ability with a visual detection limit (VDL) of 6.0 mg kg−1 in qualitative experiments and a detection limit (by a strip reader) of 1.0 mg kg−1 in semi-quantitative experiments for saury samples, with no cross-reactivity with HA analogs. Good correlation between the ICA strip with liquid chromatography-tandem mass spectrometry was achieved for spiked and naturally contaminated saury samples. Overall, this method is suitable for screening of HA residue for large scale fish samples in a quick, simple and low-cost manner.

c-axis oriented nanocrystalline Bi 2 Sr 2 Co 2 O y thin films with the average grain size of 25 nm have been achieved by chemical solution deposition combined with a rapid annealing process in oxygen. The resistivity and Seebeck coefficient of the nanostructured films are about 7.0 mΩ·cm and 171 μV/K at 873 K, resulting in a power factor 2–3 times larger than that of the best reported value in the coarse-grained Bi 2 Sr 2 Co 2 O y polycrystalline bulks. Since the thermal conductivity can be greatly reduced due to the increased phonon scattering at the grain boundaries of nanocrystalline films as well as at film surface and at film/substrate interface, great improvements in the ZT are expected in the nanocrystalline Bi 2 Sr 2 Co 2 O y thin films .

Establishing advanced sodium-ion batteries (SIBs) with high energy density and eco-friendly electrode materials are still far from satisfactory due to the large-size of sodium-ions and sluggish redox kinetics during electrochemical processes. Herein, a novel ultrafast kinetics net electrode assembled via MoSe 2 /MXene heterojunction is synthesized by a simple hydrothermal method followed by thermal annealing. Featuring the Van der Waals force interaction between MoSe 2 and MXene , the volumetric change during the sodium ions insertion/extraction courses is effectively restrained, and the reaction kinetics is greatly enhanced further. Meanwhile, both the high electrical and ion conductivity (lower diffusion barrier between Na + /MXene ~0.066 eV) provided by the unique MXene based net heterostructure of our hybrid materials, as evidenced by DFT calculations, are beneficial to the transportation of sodium ions, thus enabling an outstanding rate and long-cycling capability. As a result, the fabricated cells exhibit high reversible capacities of 490 mAh g −1 at 1 A g −1 , as well as 250 mAh g −1 at a high current of 10 A g −1 with a coulombic efficiency of 99.8%, indicating the excellent electrochemical performance of our hybrid materials, especially at high current. This novel net MoSe 2 /MXene heterostructure, combined with our simple synthesis strategy together, are expected to have great potential in sodium-ions storage application.

Calcium phosphate layers, which are widely applied on the surface of biomaterials, are important for improving tissue regeneration performance. The composition of layers formed on the surface of biomaterials differs depending on the soaking fluid. Herein, revised simulated blood fluid and fast calcification solution were investigated as immersing solutions for the mineralization of hydroxyapatite ceramics. The morphology of the hydroxyapatite particles and precipitate formation on the hydroxyapatite ceramics surface were characterized by transmission electron microscopy . Furthermore, scanning electron microscopy was used to examine the morphology of the bioactive ceramics surface. The structure of the layers was determined by selected-area electron diffraction. The prepared hydroxyapatite powders were characterized by powder X-ray diffraction. The results showed that hydroxyapatite was preferentially formed on the hydroxyapatite ceramics surface in revised simulated blood fluid and octacalcium phosphate precipitated in fast calcification solution. Additionally, the content of HCO 3 - in the mineralization fluid strongly influenced the crystal phase composition and morphology of the calcium phosphate layers on the bio-ceramics materials studied herein.

Novel, portable, probe-free, liquid cellulose biosensor was explored via a facile one-pot process for Cu 2+ ions detection by naked eyes. The as-prepared biosensor displayed specific recognition towards Cu 2+ ions in aqueous solution, even in complex urine and serum samples within 10 s, showing fast response characteristic. There is barely any interference on the Cu 2+ ions detection by other metal ions or other complex substances in urine and serum, and the corresponding detection limit is as low as 1.185, 1.9309 and 1.9154 ppm, respectively. Moreover, the cellulose biosensor could act as an excellent candidate to sense Cu 2+ ions in biological samples including urine and serum from SD rats with satisfying accuracies and biocompatibility. This study exploits a potential application of cellulose in biosensing and monitoring related to Cu 2+ ions.

Solid electrolytes could address the increasingly urgent safety and energy density concerns of lithium-ion batteries. Among several kinds of solid electrolytes, Ta-doped Li 7 La 3 Zr 2 O 12 (Ta-LLZO) became a research hotspot because of its high Li-ion conductivity and chemical stability against Li-metal and air. However, the preparation of high quality LLZO ceramic electrolyte via conventional air ambient sintering method is still a big challenge due to the serious “Li-loss” and abnormal grain growth phenomenon during the long-time high-temperature sintering process . Herein, a new rapid ultra-high-temperature air ambient sintering method without mother powder (MP) is put forward for the preparation of high quality Ta-LLZO ceramic electrolyte. The rapid sintering strategy can effectively restrain “Li-loss”. Furthermore, it is demonstrated that the none-mother-powder method is superior to traditional mother-powder method. Ta-LLZO ceramics sintered without MP via this rapid sintering method own small grain size, tight grain boundary, dense microstructure and high conductivity. Specifically, the Ta-LLZO ceramic sintered at 1360 °C for 10 min without MP exhibits high conductivity (8.5 × 10 −4 S cm −1 at 25 °C) and high relative density (97%), which equate those made by hot pressing sintering method. Without MP, the sintering process can avoid a lot of material waste and simplify the operation process. Moreover, the rapid sintering process can sharply shorten sintering time and reduce energy consumption. Therefore, this low-cost high-efficient sintering strategy can be effectively used in the large-scale production of high-quality Ta-LLZO ceramic electrolyte.

Antimony selenide (Sb 2 Se 3 ) has demonstrated considerable potential and advancement as a light-absorbing material for thin-film solar cells owing to its exceptional optoelectronic characteristics. However, challenges persist in the crystal growth, particularly regarding the nucleation mechanism during pre-selenization process for Sb 2 Se 3 . The defects originating from this process significantly impact the quality of the absorber layer, leading to the degradation in the power conversion efficiency (PCE) of the device. Herein, the evolution of pre-selenization using rapid thermal processing (RTP) on the crystallization quality of Sb 2 Se 3 film is systematically investigated. By optimizing the initial nucleation process during pre-selenization, resulting in a reduction of grain boundaries and nucleation centers, the Sb 2 Se 3 thin films demonstrate enhanced crystallinity and pinholes-free morphology. It is found that the improved quality of the grain interior and interfaces of the Sb 2 Se 3 absorber can mitigate intrinsic defects within the bulk layer, and passivate interfacial defect recombination. As a result, the short circuit current density ( J SC ) is elevated to 28.97 mA cm −2 , and a competitive efficiency of 9.03% is achieved in Sb 2 Se 3 device. This study provides comprehensive insight into the process of crystal growth and the mechanism for defect suppression, which holds guiding significance for advancing photovoltaic performance.

Selenium cathodes are expected to become next-generation energy storage materials due to their high electronic conductivity and volumetric capacity. However, their commercial applications are hindered by polyselenides dissolution and low Se utilization. Herein, a biomass compound, namely lychee seed, is used as a sustainable precursor to design hierarchically porous carbon by a single-step carbonization activation method. With a unique hierarchical porous structure, the lychee seed–derived activated carbon (LSDAC) used to encapsulate selenium delivers a reversible capacity of 446 mA h g −1 at 2 C and 291 mA h g −1 at 5 C after 1000 cycles. The Se/LSDAC electrodes show the most favorable fast-charging and good cycling behavior compared to the previously reported biomass-based carbon materials. By increasing the Se area loading to 9.5 mg cm −2 , the Se/LSDAC cathode maintains an areal capacity of 3.7 mA h cm −2 (3.2 mA cm −2 areal current density) after 80 cycles. High Se loading and economical and fast-charging cathode designs in Li–Se batteries are inspired.

The synergic effect between each component in composite membrane has created a new concept to fabricate membrane materials and widen their applications. Previous trials have suggested that micrometer-scale aramid fiber (MAF) could be effectively split into nanoscale aramid fiber (NAF) by dissolution in DMSO/KOH. Addressed herein is a time-saving approach to incorporate graphene oxide (GO) together with NAF to fabricate composite membranes through π–π stacking interactions. NAF–GO composite membranes (GO/NAF) containing gradient contents of GO have been prepared using absolute ethanol as proton donor, making the drying process facile and fast. The obtained composite membranes exhibit excellent hydrophilicity and enhanced mechanical performance. The chemical structure, morphology, crystallization and mechanical strength of GO/NAF composite membranes are characterized, respectively, and the hydrophilicity of GO/NAF is also evaluated by static water contact angle measurements. In the case of medium GO content (1 wt%) used in this study, the composite membrane possesses both optimal mechanical performance and better hydrophilicity compared to other supplementations, indicating that absolute ethanol is a promising proton donor for flocculation, which makes the post-treatment process more economic.

In this study, a new strategy combining mass spectrometric (MS) techniques with partial least squares regression (PLSR) was proposed to identify and quantify closely related adulterant herbal materials . This strategy involved preparation of adulterated samples, data acquisition and establishment of PLSR model. The approach was accurate, sensitive, durable and universal, and validation of the model was done by detecting the presence of Fritillaria Ussuriensis Bulbus in the adulteration of the bulbs of Fritillaria unibracteata. Herein, three different MS techniques, namely wooden-tip electrospray ionization mass spectrometry (wooden-tip ESI/MS), ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS) and UPLC-triple quadrupole tandem mass spectrometry (UPLC-TQ/MS), were applied to obtain MS profiles for establishing PLSR models. All three models afforded good linearity and good accuracy of prediction, with correlation coefficient of prediction ( r p 2 ) of 0.9072, 0.9922 and 0.9904, respectively, and root mean square error of prediction (RMSEP) of 0.1004, 0.0290 and 0.0323, respectively. Thus, this strategy is very promising in tracking the supply chain of herb-based pharmaceutical industry , especially for identifying adulteration of medicinal materials from their closely related herbal species.

Ultraflexible electronics have received extensive attention due to their favorable properties, such as superior mechanical robustness, light weight and good compatibility with large-area roll-to-roll fabrication. Here we present a flexible sandwiched tungsten trioxide/silver nanotrough network/poly(3,4-ethylenedioxythiophene)–poly(styrene sulfonate) multi-layer transparent conducting electrode with prominent conductivity (sheet resistance as low as 1.08 Ω sq−1) and transparency (85%). In particular, the flexible transparent electrode exhibits excellent mechanical robustness upon bending and stretching. This hybrid electrode can be further adhered tightly to a layer of WO3 to form an electrochromic device, which simultaneously displays a rapid switching time (0.75 s/1.82 s for bleaching/coloring) and high cyclic performance (86% retention of the initial optical contrast after cycling for 30 000 s). In addition, our electrode can also be fabricated on various flexible substrates, such as polyethylene cling wrap, polydimethylsiloxane and Ecoflex, with sustained electrochromic properties after bending, twisting, stretching and even strong kneading. Our work provides new opportunities for the next generation of flexible and wearable electronics applied on various flexible substrates.

Skutterudite-based thermoelectric materials have great potential for use in waste heat recovery, but the conventional melting–quench–annealing process is not suitable for large-scale fabrication. In this study, we developed a rapid fabrication technique that combines scanning laser melting and spark plasma sintering to synthesize bulk n-type and p-type filled skutterudites. The kinetics process and microstructure evolution during the scanning laser melting and annealing were systematically investigated. Due to fast solidification in scanning laser melting, the peritectic segregation size of precursor resultants is confined to several microns, which leads to great shortening of the fabrication period of filled skutterudites. The as-synthesized n-type and p-type filled skutterudites achieve excellent dimensionless figures of merit: ZT ∼ 1.23 at 850 K for Yb0.4Co4Sb12.1; ZT ∼ 1.09 at 700 K for In0.5Co4Sb12.1; ZT ∼ 0.79 at 750 K for Ce0.95Fe3CoSb12.1, which are among the highest values of single filled skutterudites. The shortened processing period and enhanced thermoelectric performance make this novel synthesis method suitable for industrial-level large-scale fabrication of skutterudite-based thermoelectric materials.
