Abstract :

Pyrite FeS2 now emerges as a promising anode for potassium-ion batteries (PIBs) due to its low cost and high theoretical capacity. However, the significant volume expansion, low electrical conductivity, and the ambiguous mechanism related to potassium storage severely hinder its development for PIBs anodes. Herein, FeS2 nanostructures are skillfully dispersed on the graphene surface layer by layer (FeS2@C-rGO) to form a sandwich structure by using Fe-based metal organic framework (Fe-MOF) as precursors. The unique structural design can improve the transfer kinetics of K+ and effectively buffer the volume expansion during cycling, thereby enhancing the potassium storage performance. As a result, the FeS2@C-rGO delivers a high capacity of 550 mAh/g at a current density of 0.1 A/g. At a high rate of 2 A/g, the capacity can maintain 171 mAh/g even after 500 cycles. Moreover, the electrochemical reaction mechanism and potassium storage behavior are revealed by in-situ X-ray diffractionand density functional theory calculations. This work not only provides a novel insight into the structural design of electrode materials for high-performance PIBs, but also proposes a valuable understanding of the potassium storage mechanism of the FeS2-based anode.(c) 2023 Elsevier Inc.

Abstract :

The increasing electromagnetic (EM) pollution that has seriously threatened human health and electronic devices urgently required high-performance absorbents toward attenuating EM wave (EMW). The com-bination of microstructure modulation and appropriate components regulation has proven to be a feasi-ble strategy for improving the EMW absorption performance of absorbents. In this work, well-designed one-dimensional carbon nanofibers with macroporous structures and uniformly magnetic metal nanoparticles modification were prepared by the hard-template assisted electrospinning method fol-lowed by carbonization and template-elimination processes. The strong interfacial polarization loss and multireflection strengthened by the hollow structures and the magnetic loss induced by the intro-duced cobalt nanoparticles evidently enhanced the impedance matching level of the macroporous carbon nanofibers/cobalt nanoparticles (MCF/Co). As a result, MCF/Co composite offers broad absorption band-width (6.24 GHz) and strong electromagnetic wave absorption performance (-40.1 dB) at a thickness of 3.0 mm. This work inspires the rational one-dimensional macroporous carbon nanofibers design for new-generation EMW materials and provides an important research basis for the porous flexible EMW absorption materials.(c) 2023 Elsevier Inc.

Abstract :

Sodium-ion batteries (SIBs) are expected to replace lithium-ion batteries in the energy storage sector owing to their low cost and abundant resources. However, developing suitable anode materials to meet the high energy density requirements of SIBs remains an ongoing challenge. Herein, we design a hollow nitrogen-doped bowl-like carbon decorated with Co9S8 nanoparticles linked by carbon nanotubes (HNBC@Co9S8@CNTs) as an anode material for SIBs. The HNBC@Co9S8@CNTs electrode exhibits impressive rate performance (449.3 mAh g-1 at 5 A g-1) and cycling stability (426.5 mAh g-1 after 500 cycles at high current density of 1 A g-1) due to the advantages of highly conductive three-dimensional (3D) interconnected structures. In addition, its pseudo - capacitance and sodium storage diffusion kinetics are analyzed in depth using Cyclic Voltammetry (CV) and galvanostatic intermittent titration technique (GITT). The results elucidate that the partially surface-induced capacitive sodium storage, highly conductive 3D interconnected structures, and fast reaction kinetics synergis- tically contribute to the high-rate performance. This work may provide new insights for the fabrication of various metal sulfide or sulfide composites with high sodium storage capacity.

Abstract&Keyword Cite

Abstract :

This paper reports the synthesis of multi-layer SiO2@Au@SiO2@QDs nanoparticles with a dual-functionality of simultaneous heating and temperature sensing and their applications to in vitro chemo-thermal therapy. The heating is activated by a NIR-light through resonance excitation of surface plasma while in-situ thermal sensing is accomplished by the QDs photoluminescent (PL) effect. These dual function nanoparticles are used as a drug carrier for in vitro chemotherapy-photothermal co-treatment for malignant cells. A comparative study of drug release profiles was performed with and without 808 nm laser irradiation. The drug release rate was accelerated by a rise of temperature, which is induced by plasmonic heat generation associated with Au nanoshells; while the temperature change is monitored by the QD nanoparticles at the same time. The results showed that SiO2@Au@SiO2@QDs-DOX platform enabled the combination of local specific chemotherapy with external near-infrared (NIR) photothermal therapy and significantly improved the efficacy of cancer treatment. This combined treatment demonstrated synergistic chemotherapeutic-thermal effects compared to chemotherapy or photothermal therapy alone, resulting in higher efficacy.

Abstract :

Cyanide bridged frameworks are excellent pre-catalysts towards oxygen evolution reaction. Control the hydrolysis product is crucial for design of highly active catalyst. Herein, we introduced pyrazine molecules pillared Hofmann-type metal organic framework electrocatalysts. The in-situ formed amorphous hydroxide provided high electrocatalytic activity and the interplanar pyrazine molecule offered structural stability towards alkaline environment, which effectively boosted the OER catalytic activity by offering more accessible active sites. The enhanced structural stability was justified by Raman spectroscopy. The overpotential, Tafel slope, and turn over frequency of the as-synthesized Hofmann-type MOF reached 306 mV, 15.6 mV dec(-1) and 0.12 s(-1), which is significantly better than that of Prussian blue analogue. This work justified the effectiveness of the ligand stabilization strategy in boosting the activity in OER catalysts.

Expanding the active charge carriers of polymer electrolytes in lithium-based batteries using an anion-hosting cathode SCIE Scopus
期刊论文 | 2022 , 13 (1) | NATURE COMMUNICATIONS
Abstract&Keyword Cite

Abstract :

The energy content of secondary batteries is often limited by the charge carriers available in the system. Here, the authors employed an anion acceptor cathode for simultaneous use of electrolyte anions and cations as effective charge carriers in solid polymer electrolytes for lithium-based batteries. Ionic-conductive polymers are appealing electrolyte materials for solid-state lithium-based batteries. However, these polymers are detrimentally affected by the electrochemically-inactive anion migration that limits the ionic conductivity and accelerates cell failure. To circumvent this issue, we propose the use of polyvinyl ferrocene (PVF) as positive electrode active material. The PVF acts as an anion-acceptor during redox processes, thus simultaneously setting anions and lithium ions as effective charge carriers. We report the testing of various Li||PVF lab-scale cells using polyethylene oxide (PEO) matrix and Li-containing salts with different anions. Interestingly, the cells using the PEO-lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) solid electrolyte deliver an initial capacity of 108 mAh g(-1) at 100 mu A cm(-2) and 60 degrees C, and a discharge capacity retention of 70% (i.e., 70 mAh g(-1)) after 2800 cycles at 300 mu A cm(-2) and 60 degrees C. The Li|PEO-LiTFSI|PVF cells tested at 50 mu A cm(-2) and 30 degrees C can also deliver an initial discharge capacity of around 98 mAh g(-1) with an electrolyte ionic conductivity in the order of 10(-5 )S cm(-1).

Abstract :

Gel-based ionic conductors are promising candidates for flexible electronics, serving as stretchable sensors or electrodes. However, most of them suffer from a short operating life, low conductivity and rely on an external power supply, limiting their practical application. Herein, we report a stable organogel ionic conductor with high conductivity and self-powering ability. Briefly, lithium trifluoromethanesulfonate, as a conductive salt, provides high conductivity and the poly(1,1difluoroethylene) layers, as a self-powering system, supply stable energy output under the influence of pressure. Moreover, the proposed conductors withstand long-term and multi-cycle durability tests. The prepared auxiliary training device can withstand the impact of a basketball and detect the impact force, showing potential in passive sensing during practical applications.

Abstract :

The photoelastic effect has many uses in mechanics today, but it is usually disregarded in flexible materials. Using 2-phenoxyethyl acrylate as a monomer and 4-cyano-4'-pentylbiphenyl (5CB) as a solvent, a multiple responsive photoelastic organogel (PO) with strong birefringence but low modulus is created. 5CB is a liquid crystal molecule that does not participate in the polymerization process and is always present as tiny molecules in the polymer. It endows the PO low modulus and high birefringence, as well as the ability to drive the birefringence using an electric field. This PO not only has high sensitivity and fast response as a photoelastic strain sensor, but also has a very sensitive response to heat, especially in the range of human body temperature. It also has a high dielectric constant and a strong correlation between the interference color and the applied electric field, allowing for easy writing and erasure of encrypted data. This unique multisignal response feature and low modulus that mimics human skin bring up new opportunities in the potential applications such as multiple information encryption, anticounterfeiting, and multifunctional wearable sensors.
