Lithium-sulfur (Li-S) batteries with a theoretical energy density of 2567 Wh kg −1 are very promising next-generation energy storage systems, but suffer from the insulativity of sulfur and Li 2 S, the shuttle effect due to the dissolution and migration of polysulfides, and the lithium dendrite issue. MXenes, a family of 2D transition metal carbides/nitrides, which have metallic conductivity, structural variety, strong chemical adsorption ability to polysulfides, effective catalytic effect for fast kinetics, and inducing effect for uniform growth of Li, exhibit promising potential for high-performance Li-S batteries. In this review, the recent progress and achievements of MXene-based Li-S batteries are summarized, including the use of MXenes in sulfur cathode, interlayer between cathode and separator, and Li anode. The architecture construction and chemical modification of MXenes, as well as hybridization with other materials are demonstrated. The enhancement on electrochemical performance and the related mechanisms of MXenes and MXene-based composites are discussed. Finally, challenges and perspectives of MXenes for Li-S battery application are also given.

The purpose of this paper is to present advanced techniques in optical biodevices. Moreover different configurations involving the generation of fiber optical biosensors are described. To overcome some limitations of fiber optical biosensors, plasmonic phenomena proposed. In addition novel plasmonic phenomena have broaden researcher’s horizons in new discovering in terms of technology and application. As regards there are many challenges to detect ultra-low concentration samples with high sensitivity in real time. Researchers have always made great efforts to discover more effective methods. Throughout the paper SPR and LSPR as a powerful analysis instrument are introduced. Finally surveys the current practical performances of plasmonic sensors in detection of bio target are provided. As a result these devices demonstrate great potential in identifying target analytic due to their unique optical biosensors.

“…Moreover, the MXene −OH termination groups have been shown to form thiosulfates and electrochemically active [26] polythionates by reacting with polysulfides, [31] which represents a third important polysulfide confinement mechanism [26] . Adding hydrophilicity, excellent mechanical properties, and structural flexibility, [29] it is not surprising MXenes have been intensively reported both as a cathode constituent [30–52] and as an interlayer between the cathode and the separator [33,36,43,48,53–59] for Li‐S batteries. The main disadvantages of MXenes are the typical preparation route via toxic HF etching and that they are prone to restack, causing a low surface area [13] .…”

The realization of sustainable and cheap Mg‐S batteries depends on significant improvements in cycling stability. Building on the immense research on cathode optimization from Li‐S batteries, for the first time a beneficial role of MXenes for Mg‐S batteries is reported. Through a facile, low‐temperature vacuum‐filtration technique, several novel current collector‐ and binder‐free cathode films were developed, with either dipenthamethylene thiuram tetrasulfide (PMTT) or S8 nanoparticles as the source of redox‐active sulfur. The importance of combining MXene with a high surface area co‐host material, such as carbon nanotubes, was demonstrated. A positive effect of MXenes on the average voltage and reduced self‐discharge was also discovered. Ascribed to the rich polar surface chemistry of Ti3C2Tx MXene, an almost doubling of the discharge capacity (530 vs. 290 mA h g−1) was achieved by using MXene as a polysulfide‐confining interlayer, obtaining a capacity retention of 83 % after 25 cycles.
