A catheter applicable in endovascular radiofrequency ablation in blood vessels such as renal arteries. From the proximal end to the distal end, the catheter comprises: a control handle (5), a main body segment (1), a bendable segment (2), and an electrode (4), where a pull wire (10) runs through the interior of the catheter and is controlled by the control handle (5). The catheter also comprises a straight end-segment (3). The electrode (4) is fixed onto the straight end-segment (3). The pull wire (10) is fixed at one end thereof to the distal end of the straight end-segment (3), while the pull wire (10) is arranged in that, along the axis of the catheter, the pull wire (10) extends on different sides respectively in the straight end-segment (3) and in the bendable segment (2). The catheter allows for adaptation to different renal artery inner diameters, for enhanced wall-attaching effect of the electrode, while the catheter is simple to operate, safe, and reliable for use in sympathetic nerve radiofrequency ablation of the renal arteries.

The invention discloses a preparation method for stable full-inorganic perovskite A2PdX6 nanocrystalline with no lead and low band gap (A=Cs, Rb, K or multiple mixing; X=Cl, Br, I or multiple mixing thereof), the preparation method takes A2PdX6 micron-crystalline as a precursor material, and then the nanocrystalline is synthesized by using a rapid antisolvent method, the main synthesis process isas follows: Firstly, A2PdX6 micron-crystalline is synthesized by a solution method or a solid phase method; then the obtained A2PdX6 micron-crystalline is dissolved in a strong polar solvent under heating condition to obtain a clear and transparent precursor solution; after the precursor solution is cooled to room temperature, a certain amount of the precursor solution is rapidly added to the antisolvent under the stirring condition, and A2PdX6 nanocrystalline colloidal solution with a particle size about 3 nm is rapidly formed, the synthesis method provided by the invention is fast, simple, can be operated at normal temperature, has good reproducibility and is environmentally friendly; at the same time, the product has uniform size, good dispersibility, high stability and excellent photoelectric response; the preparation method can be used in fields such as light or photoelectrocatalysis, photodetectors, solar cells.

The invention relates to a method for preparing a periodic graphene PN junction on an n-type 4H / 6H-SiC silicon surface, which belongs to the technical field of microelectronic materials. The method includes the steps of: semi-insulating and forward n-type 4H / 6H‑SiC silicon surface wafer is chemically mechanically polished and chemically cleaned, and n-type single-layer graphene is prepared on an off-axis 4° semi-insulating SiC wafer, and n-type single-layer graphene micro-stripes are obtained through the stripping step. Prepare p-type single-layer graphene microstrips on n-type SiC substrates, align n-type single-layer graphene microstrips and place them on p-type single-layer graphene microstrips, apply pressure, and place the sample Heating on a heating platform, the tape is detached to obtain a periodic PN junction. The method is easy to control, and by precisely controlling the growth pressure, time, etc., a high-quality periodic graphene PN junction with uniform surface morphology is finally obtained on the Si surface of the n-type 4H / 6H-SiC substrate.
