The present work proposes a novel strategy to fabricate an integrated architecture of gel polymer electrolyte （GPE）-nanoarray cathode for lithium-O2 batteries （LOBs）. As a proof-of-concept experiment, the photo-initiated in situ polymerization of GPE was carried out via incorporating the precursor solution in advance into a self- standing binder-free oxygen electrode of Co3O4 nanosheets array grown on carbon cloth （Co3O4@CC）, forming an integrated GPE-Co3O4@CC architecture. The performance of the solid-state LOBs using the GPE-Co3O4@CC assembly is greatly enhanced compared to the counterparts with a traditional cell structure, in which GPE was sandwiched by a lithium metal and a cathode. The enhanced performance is ascribed to the combination of the in situ polymerization of GPE and the versatile structure of nanoarray electrode, which results in abundant interfacial contacts between GPE and electrode. This work presents an alternative way to develop high-performance solid-state LOBs by combining the advantages of both gel polymer electrolytes and nanoarray electrodes.

It is still a great challenge for semiconductor based-devices to obtain a large magnetoresistance（MR） effect under a low magnetic field at room temperature. In this paper, the photoinduced MR effects under different intensities of illumination at room temperature are investigated in a semi-insulating gallium arsenide（SI-Ga As）-based Ag/SI–Ga As/Ag device. The device is subjected to the irradiation of light which is supplied by light-emitting diode（LED） lamp beads with a wavelength in a range of about 395 nm–405 nm and the working power of each LED lamp bead is about 33 mW. The photoinduced MR shows no saturation under magnetic fields（B） up to 1 T and the MR sensitivity S（S = MR/B） at low magnetic field（B = 0.001 T） can reach 15 T^（-1）. It is found that the recombination of photoinduced electron and hole results in a positive photoinduced MR effect. This work implies that a high photoinduced S under a low magnetic field may be obtained in a non-magnetic semiconductor device with a very low intrinsic carrier concentration.

The triglyceride-glucose (TyG) index has emerged as a reliable surrogate marker for assessing insulin resistance, emphasizing the need for a rapid and precise technique to quantify blood glucose and triglyceride levels. In this study, we have developed a mid-infrared fiber evanescent wave spectroscopic (MIR-FEWS) sensor, tapered from Ge 10 As 20 Ga 5 Se 65 infrared fiber, for the simultaneous analysis of both triglyceride and glucose. This innovative sensor achieves a low limit of detection (LoD) of 1.18 mM for glucose and 0.23 mM for triglycerides, respectively, showcasing its possibility for blood test. Moreover, the sensor exhibits excellent repeatability and stability, validating its applicability for determining the TyG index in whole blood. When applied to measure the TyG index in Sprague-Dawley (SD) rats, the results closely align with those from commercial blood glucose and lipid meters, underscoring its accuracy. The proposed MIR-FEWS sensor has multiple advantages, including multi-component analysis capabilities, high sensitivity, straightforward operation, label-free measurement, and cost-effectiveness, thereby presenting a novel and promising technique for rapid and reliable TyG index detection.

Spinal cord regeneration is a highly intricate physiological process. A material designed for a single function may struggle to swiftly adapt to a delicate regulatory microenvironment, which can cause delays in nerve regeneration and limit functional recovery. To address this, we have devised a multifunctional tissue engineering approach that uses endogenous reactive oxygen species (ROS) production to trigger the on-demand release of hydrogen sulfide (HS) at the injury site. This targeted delivery aims to facilitate spinal cord repair, neuroprotection, and neuroregeneration. Our delivery system incorporates a HS donor (peroxyTCM) with ROS-responsive triggers integrated into a zinc-citrate metal-organic framework (Zn-CA MOF) (PTCM@Zn-CA), which is then encapsulated within a composite hydrogel (GelMA@LAMC). This integrated strategy considerably boosts the regeneration of spinal cord injury (SCI) through the physiological benefits of HS and zinc ions. Specifically, it can mitigate oxidative stress and inflammation, induce macrophage M2 phenotype polarization, protect nerve cells, promote angiogenesis, and restore mitochondrial function to normalcy. Using pleiotropic messengers in tissue regeneration holds great promise for the effective repair of SCI.

Biological materials are well worth learning for our own synthetic materials. It’s of great interest that the growth rate of teeth is different in species. The growth rate of human teeth is slow, but faster for rat and shark. The microstructure and composition difference may have a great effect on the growth rate. In this study, the microstructure and composition from human teeth, rat teeth and shark teeth were well characterized by scanning electron microscopy and X-ray diffraction. It is demonstrated that the size of individual apatite crystal and the growth direction of apatites in those enamel or enameloid display different types. The diameter of shark enameloid is the biggest. Three growth directions can be observed in shark enameloid but only two in human and rat. The main inorganic composition of the three teeth is also different. It is hydroxyapatite (HAP) for human and rat teeth, while fluorapatite (FAP) for shade. The XRD patterns also indicate that the assemble degree of human teeth is the most sophisticated. The results may give useful insight into new materials synthesis technology. © 2019, American Ceramic Society. All rights reserved.

Ammonium-ion batteries (AIBs) have recently attracted increasing attention in the field of aqueous batteries owing to their high safety and fast diffusion kinetics. The NH storage mechanism is quite different from that of spherical metal ions (e.g. Li , Na , K , Mg , and Zn ) because of the formation of hydrogen bonds between NH and host materials. Although many materials have been proposed as electrode materials for AIBs, their performances hardly meet the requirement of future electrochemical energy storage devices. It is thus urgent to design and exploit advanced materials for AIBs. This review highlights the state-of-the-art research on AIBs. The insights into the basic configuration, operating mechanism and recent progress of electrode materials and corresponding electrolytes for AIBs have been comprehensively outlined. The electrode materials are classified and compared according to different NH storage behaviour in the structure. The challenges, design strategies and perspectives are also discussed for the future development of AIBs.

Nanosized energy storage, energy-harvesting, and functional devices are the three key components for integrated self-power systems. Here, we report on nanoscale electrochemical devices with a nearly three-fold enhanced stored charge under the field effect. We demonstrated the field-effect transistor can not only work as a functional component in nanodevices but also serve as an amplifier for the nanosized energy storage blocks. This unusual increase in energy storage is attributed to having a wide range of accessible electronic density of states (EDOS), hence redox reactions are occurring within the nanowire and not being confined to the surface. Initial results with MoS2 suggest that this field effect modulated energy storage mechanism may also apply to many other redox-active materials. Our work demonstrates the novel application of the field-effect in energy storage devices as a universal strategy to improve ion diffusion and the surface-active ion concentration of the active material, which can greatly enhance the charge storage ability of nanoscale devices. The fabrication process of the field-effect energy storage device is also compatible with microtechnology and can be integrated into other microdevices and nanodevices. Copyright © 2021, The Authors.

Bismuth oxide(Bi2O3) has received great attention as an anode material for alkaline nickel/bismuth(Ni/Bi) batteries due to its high theoretical capacity and easy preparation. However, the generally poor conductivity of metal oxides and the instability of Bi2O3 during cycling severely limit the device performance. Herein, we present the use of directly grown Bi2O3 nanoflake film with kinetic advantages as the anode for Ni/Bi batteries. Particularly, glucose-derived carbon is integrated onto the surfaces of nanoflakes, which not only enhances the electron transfer but also buffers the conversion-reaction induced volume expansion of Bi2O3, helping maintaining the cycling stability of the film. The resulting Bi2O3@C electrode exhibits high specific capacity, excellent rate performance(can be charged within 6.7 s), and good cycle stability(~1,200 times;fading rate of only 0.011% per cycle).When assembled with a nickel oxide(NiO) nanosheet array cathode in basic electrolyte, a fully binder-free Ni/Bi battery is obtained, which delivers maximum energy and power densities of 34.29 W h kg-1 and 12,159.8 W kg-1, respectively, and good cycling performance. The power density is even much superior to that of many hybrid/asymmetric *** work suggests a new generation of thin-film Ni/Bi batteries for potential high-power electronic applications.

Sensitive, on-site and multiple detection of mycotoxins is a vital early-warning tool to minimize food losses and protect human health and the environment. Although paper-based lateral flow immunoassay (LFIA) have been extensively applied in mycotoxins monitoring, low-cost, portable, ultrasensitive and quantitative detection is still a formidable challenge. Herein, a series of Fe-N-C single-atom nanozymes (SAzymes) were synthesized and systematic characterized. The optimal Fe-N-C SAzyme with highly efficient catalytic performance was successfully used as both label and catalyst in lateral flow immunoassays for mycotoxin detection. By taking advantage of the catalytic amplified system, the qualitative and quantitative detection can be easily and flexibly done via observing the test lines by naked eyes or a smartphone, with the LODs of 2.8 and 13.9 pg mL -1 for AFB 1 and FB 1 , which were respectively over 700- and 71000-fold lower than the maximum limit set by the European Union. Besides, underlying catalytic mechanisms and the active sites of the Fe-N-C SAzyme are also investigated by DFT simulation. This work not only provided a promising detection strategy for the application of advanced SAzymes but also offers experimental and theoretical guidelines to understand the active centers of Fe-N-C SAzymes and the catalytic process. © 2022, The Authors.

Two-dimensional (2D) materials, with their atomic-layer thickness and exceptional properties, have garnered significant attention for next-generation integrated circuits. Among these, 2D antimony (Sb)-based materials distinguish themselves through outstanding physical properties, natural abundance, and remarkable stability. Despite their potential, a comprehensive review summarizing advancements in 2D Sb-based materials remains absent. This review addresses this critical gap by presenting an in-depth analysis of recent progress in 2D Sb-based materials, specifically, antimonene, antimony chalcogenides (SbX, X = S, Se, Te), antimony oxides (α-, β-, and γ-SbO, and SbO), antimonides (e.g., NdSb), and complex polycompounds such as quaternary CdSbSeBr, focusing on their crystal structures, synthesis techniques, applications, and future prospects. By providing valuable insights into the potential of 2D Sb-based materials, our review aims to inspire further research into their practical applications and address the challenges that lie ahead for future electronics and optoelectronics.
