Abstract: A non-aqueous electrolyte and a lithium-ion battery containing the non-aqueous electrolyte. The non-aqueous electrolyte contains a lithium salt, an organic solvent, and an additive. The additive contains 2-phenyl-benzothiazole and a derivative thereof, and can form a passive film on the surface of a positive electrode when a lithium-ion battery is overcharged, so as to prevent the voltage of the battery from further increasing during overcharging; the additive makes the temperature of the electrolyte rise slower during overcharging; and the addition of the additive not only do not affect the room temperature cycle performance of the lithium-ion battery, but also can even improve the room temperature cycle performance of the lithium-ion battery, thereby effectively avoiding the potential safety hazards caused by battery overcharging.

Abstract: A method for preparing a fully soft self-powered vibration sensor mainly uses a laser carbonization technology to prepare a two-dimensional porous carbon electrode with an origami structure, and then transfers the two-dimensional porous carbon electrode to a three-dimensional polydimethylsiloxane (PDMS) cavity through mold transfer; finally, a laser engraving technology is used to create microstructures on surfaces of the porous carbon electrode and a PDMS film. The sensor includes the PDMS film, a liquid metal droplet oscillator, a porous out-of-plane carbon electrode, and a 3D PDMS cavity assembled tightly from top to bottom.

Abstract: A long-lasting hydrogel for use against drug-resistant bacteria, and a preparation method and use thereof are provided. In the present disclosure, polyvinyl alcohol (PVA) is mainly adopted as a matrix, and phytic acid and honey including glucose and fructose are added to modify the PVA to obtain the hydrogel. During preparation of the antimicrobial hydrogel, no toxic chemical crosslinking agent or initiator is added, and the antimicrobial hydrogel is mainly obtained by crosslinking PVA, phytic acid, and monosaccharides through ester bonds, hydrogen bonds, and electrostatic adsorption. In addition, the hydrogel obtained by adding phytic acid and honey to the PVA matrix exhibits a significant long-lasting antimicrobial effect for Staphylococcus aureus (S aureus), drug-resistant S. aureus, and Pseudomonas aeruginosa (P. aeruginosa), and the antimicrobial effect can last for about 3 months.

Abstract: A method of fabricating a flexible surface plasmon resonance, SPR, film, a method of performing Surface enhanced Raman Spectroscopy, SERS, a flexible surface plasmon resonance, SPR, film, and a SERS system. The method of fabricating a flexible SPR film comprises the steps of depositing a metal film on a ductile poly (?-caprolactone), PCL-based film having a first length to form a composite PCL-based film; and stretching the composite PCL-based film such that the ductile PCL-based film undergoes an irreversible transformation to form the SPR film exhibiting a second length that is larger than the first length.
