In addition, it has low cytotoxicity to normal cells and no effect on the main organs of mice. It paves a brand new avenue to develop smart and facile diagnosis and a treatment platform for bacterial infections.Nonuniform electrodeposition and dendritic growth of lithium metal coupled to its chemical incompatibility with liquid electrolytes are largely responsible for poor Coulombic efficiency and safety hazards preventing the successful implementation of energy-dense Li metal anodes. https://www.selleckchem.com/products/protac-tubulin-degrader-1.html Artificial solid electrolyte interface (ASEI) layers have been proposed to address the morphological evolution and chemical reactions in Li metal anodes. In this study, an ASEI layer consisting of a lithium phosphorus oxynitride (LiPON) thin film electrolyte and gold-alloying interlayer was developed and shown to promote the electrodeposition of smooth, homogeneous, mirror-like Li metal morphologies. The Au layer alloyed with Li, reducing the nucleation overpotential and resulting in a more spatially uniform metal deposit, while the LiPON layer provided a physical barrier between the Li metal and aprotic liquid electrolyte. The effectiveness and integrity of the LiPON protective layer was assessed using in operando impedance spectroscopy and ex situ SEM/EDS characterization. Smooth, homogeneous Li morphologies were realized in capacities up to 3 mAh cm-2 plated at 0.1 mA cm-2. At higher current densities up to 1 mA cm-2 or increased deposition capacities of 6 mAh cm-2, the LiPON coating fractured due to the localized, nonuniform lithium deposits and rough, dendritic Li morphologies were observed. This approach represents a new strategy in the design of artificial SEIs to enable Li metal anodes with practical areal capacities.In order to satisfy the increasing requirements on operation time of wearable and portable electronic devices, novel self-powered systems by integrating triboelectric nanogenerator (TENG) with an energy storage device have emerged as a promising technology to provide sustainable power. Here, a flexible sodium composite anode (Na@CC) was prepared by infusing the molten sodium into flexible sodiophilic carbon cloth. The symmetric cell with the Na@CC anode shows stable sodium plating and stripping for 400 h. The full cell with a flexible quasi-solid-state electrolyte, Na3V2(PO4)3@C nanofiber cathode, and Na@CC anode delivers an excellent rate capacity of 72.5 mAh g-1 at 5 C and also exhibits stable cycling performance under different bent degrees. By combining with TENG to form a self-powered system, the flexible quasi-solid-state sodium battery can effectively store the pulse current and shows stable discharging capacity for over 100 cycles. The advanced flexible battery demonstrates its capability as a promising energy storage part in combination with TENGs and shows great potential in powerful flexible self-powered systems.Cyclohexane-1,2,4,5-tetracarboxylic diimide with a nonconjugated core has been incorporated to bridge two conventional triphenylamine units. The obtained monomer has successfully hypsochromically shifted the maximum absorption wavelength by 10 nm in comparison to the one with a pyromellitic diimide bridge. Consequently, a colorless electrochromic (EC) polymer poly(bis(N,N-diphenyl-4-aminophenyl)cyclohexane-1,2,4,5-tetracarboxylic diimide) (PTPA-HDI) was electropolymerized on indium tin oxide (ITO)-coated glass. The morphology, absorption, and spectroelectrochemistry properties of polymer PTPA-HDI films electropolymerized by different scan cycles have been systematically investigated. It is found that comprehensive properties, such as color contrast and initial transparence, can be achieved for the polymer film electropolymerized by 15 scan cycles. Moreover, to realize colorless-to-black electrochromism, an asymmetric viologen derivative 1-(4-cyanophenyl)-1'-hexyl-4,4'-bipyridinium dihexafluorophosphate (HVCN)to design multifunctional displays.CH4 production from CO2 hydrogenation provides a clean approach to convert greenhouse gas CO2 into chemical energy, but high energy consumption in this reaction still restrains its further application. Herein, we use a light-driven CO2 methanation process instead of traditional thermocatalysis by an electrical heating mode, with the aim of greatly decreasing the energy consumption. Under UV-vis-IR light irradiation, the photothermal CO2 methanation over highly dispersed Co nanoparticles supported on Al2O3 (Co/Al2O3) achieves impressive CH4 production rates (as high as 6036 μmol g-1 h-1), good CH4 selectivity (97.7%), and catalytic durability. The high light-harvesting property of the catalyst across the entire solar spectrum coupled with its strong adsorption capacity toward H2, CO2, CO, and abundant active sites are proposed to be responsible for the better photothermocatalytic performance of Co/Al2O3. Furthermore, a novel light-promotion effect is also revealed in CO2 methanation, where UV-vis light irradiation induces oxygen vacancies and improves the proclivity toward adsorption of H2, CO2, and CO, finally resulting in a significant enhancement of the photothermocatalytic activity for CH4 production. By concentrating the low-intensity light (120 mW/cm2) via a Fresnel lens, a photothermal CO2 conversion efficiency of more than 50% with a good CH4 selectivity (76%) is achieved on the optimal catalyst under a dynamic reaction system, which indicates the bright prospect of photothermal CO2 methanation.In this work, Li-rich Li1.2Mn0.43+Mn x 4+Ti0.4-xO2 (LMM x TO, 0 ≤ x ≤ 0.4) oxides have been studied for the first time. X-ray diffraction (XRD) patterns show a cation-disordered rocksalt structure when x ranges from 0 to 0.2. After Mn4+ substitution, LMM0.2TO delivers a high specific capacity of 322 mAh g-1 at room temperature (30 °C, 30 mA g-1) and even 352 mAh g-1 (45 °C, 30 mA g-1) with an energy density of 1041 Wh kg-1. The reason for such a high capacity of LMM0.2TO is ascribed to the increase of both cationic (Mn) and anionic (O) redox after Mn4+ substitution, which is proved by dQ/dV curves, X-ray absorption near edge structure, DFT calculations, and in situ XRD results. In addition, the roles of Mn3+ and Ti4+ in LMM0.2TO are also discussed in detail. A ternary phase diagram is established to comprehend and further optimize the earth-abundant Mn3+-Mn4+-Ti4+ system. This work gives an innovative strategy to improve the energy density, broadening the ideas of designing Li-rich materials with better performance.
