This utility model relates to the field of trousers technology and discloses a three-dimensional cut trousers, including a front piece (1), a back piece (2), a hip piece (3), and a leg piece (4). The front piece (1) includes a first groove (11) located at the knee and a first arc-shaped part (12) extending from the first groove (11) toward the back of the leg. The back piece (2) includes a second arc-shaped part (21) that matches the first groove (11) and covers the knee, a second groove (22) that matches the first arc-shaped part (12), and a connecting leg part (23) located on one side of the second groove (22). The connecting leg part (23) extends from the back of the thigh, through the outside of the calf, to the front of the calf. The trousers adopt a three-dimensional cut process to form a spliced ​​structure at the knee. The cut curves formed conform to the curves of the human body, which is not only beautiful but also has a significant effect on modifying the leg shape, improving the comfort of wearing, and is suitable for a wider range of people.

This invention belongs to the field of optical thin film technology for optical devices, and relates to a ligand and a method for modifying metal oxide nanoparticles using this ligand, as well as its applications. This method of modifying metal oxide nanoparticles using a multi-branched ligand containing phosphate groups achieves precise control of reaction conditions and environment through a multi-ligand combination-step reaction modification approach. This results in a richer effect of the surface organic components of the metal oxide nanoparticles, exhibiting more transparent organic dispersion under high concentrations of the same inorganic particles. Furthermore, the multi-branched ligand containing phosphate groups shows higher reactivity with the surface of hydroxylated metal oxide nanoparticles, resulting in a more significant modification effect, with the surface organic ligand accounting for no less than 20% by thermogravimetric analysis.

The present invention relates to a sodium secondary battery electrolyte and a sodium secondary battery. The sodium secondary battery electrolyte comprises an organic solvent, an electrolyte sodium salt and a fluorine-containing additive having a structure shown in formula (I), wherein R1, R2, R3, R4 and R5 are independently selected from -H, halogen, C1-C 20 Alkyl, halogenated C1~C 20 Alkyl, C6~C 26 Aryl or halogenated C6~C 26 Aryl. The sodium secondary electrolyte can reduce the irreversible decomposition reaction of the electrolyte, significantly improve the cycle stability, capacity retention rate and coulomb efficiency of the electrolyte, and can also significantly inhibit the increase of electrolyte acidity and chromaticity. When applied to sodium secondary batteries, it can induce the formation of a stable, low-impedance passivation film on the electrode surface, further improve the battery's cycle performance, and promote more uniform sodium plating and stripping on the sodium metal surface. It can also reduce the contact angle between the electrolyte and the electrode, improve wettability, and facilitate sodium ion transmission. #imgabs0#
