| 1 | A safe,low-cost and high-efficiency presodiation strategy for pouch-type sodium-ion capacitors with high energy density显示文摘Sodium-ion capacitors(SICs)have attracted appreciable attention in virtue of the higher energy and power densities compared with their rivals,supercapacitors and sodium-ion batteries.Due to the lack of sodium resources in cathode,presodiation is critical for SICs to further augment performances.However,current presodiation strategy utilizes metallic sodium as the presodiation material.In this strategy,assembling/disassembling of half-cells is required,which is dangerous and in creases the time and cost of SIC leading to the restriction of their industrialization and commercialization.Herein we present a safe,low-cost and high-efficiency presodiation strategy by first employing Na_(2)C_(2)O_(4) as the sacrificial salt applied in SICs.Na_(2)C_(2)O_(4) is environmentally friendly and possesses considerably low expenditure.No additional residues remain after sodium extraction ascribed to its'zero dead mass'property.When paired with commercial activated carb on as the cathode and commercial hard carbon as the ano de,the constructed pouch-type SICs exhibit high energy and power densities of 91.7 Wh/kg and 13.1 kW/kg,respectively.This work shows a prospect of realizing the safe and low-cost manufacturing for high-performance SICs commercially. | Congkai Sun Xiong Zhang Chen Li Kai Wang Xianzhong Sun Fangyan Liu Zhong-Shuai Wu Yanwei Ma | 2022 | Journal of Energy Chemistry2022，31，1： | 3 |
| 2 | Carvacrol combined with NIR light-responsive nano-drug delivery system with specific anti-bacteria,anti-inflammation,and immunomodulation for periodontitis显示文摘Bacterial infection,biofilm formation,immune dysfunction are common triggers and aggravators in periodontitis,which render periodontal restoration challenging.Thus,a strategy with antibacterial,anti-inflammatory,immunoregulatory capacities has great promise in the clinical practice of periodontitis.Herein,carvacrol(CA)-based near-infrared(NIR)lightresponsive nano-drug delivery system is developed for the first time.The system consists of upconversion nanoparticles(UCNPs,which upconvert 808 nm NIR to blue light),mesoporous silica(mSiO_(2),the carrier channel),hydrophobic CA(blue light response properties).Under the irradiation of 808 nm NIR,owing to the synergy of CA and upconverted blue light,the UCNPs@mSiO_(2)-CA(UCMCs)exhibit the properties of specific anti-bacteria(including anaerobic bacteria),anti-inflammation,and immunomodulation.Notably,high-throughput sequencing results exhibit that many classic inflammatory immune-related signaling pathways,including the MAPK signaling pathway,tumor necrosis factor(TNF)signaling pathway,IL-17 signaling pathway,are enriched to remodel the immune microenvironment.Additionally,UCMCs with NIR irradiation accelerate periodontal restoration and serve as promising non-invasive management of periodontitis.Altogether,this study verifies the feasibility of herbal monomer combined with light-responsive in situ nano-drug delivery system and provides a more effective and reliable strategy for various potential applications of deep tissue diseases. | Daorun Hu Congkai Zhang Chao Sun Haijing Bai Jialiang Xie Yawen Gu Mengyuan Li Junkai Jiang Aiping Le Jiaxuan Qiu Xiaolei Wang | 2023 | Nano Research2023，16，5： | 0 |
