Abstract: Provided area hydrophobic and self-cleaning resin slurry, and a hydrophobic and self-cleaning resin dental material and use thereof, which relate to the technical field of dental materials. In the disclosure, the hydrophobic and self-cleaning resin slurry includes the following raw materials: a dimethacrylate monomer, triethylene glycol dimethacrylate, perfluoroalkyl acrylate, a diluent, nano-silica, ?-methacryloxypropyltrimethoxysilane, camphorquinone, and a photo-curing accelerator.

Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

Abstract: A pressure cooking appliance is provided. The pressure cooking appliance comprises a cooker body and a lid, the lid comprising an upper lid portion, and a lower lid portion lockingly covering the cooker body to form a pressurized cooking chamber therebetween. The upper lid portion covers the lower lid portion from above, and comprises a main lid body and a removable cover, the main lid body comprising an opening portion formed at a central portion of the main lid body for exposing the lower lid portion, the removable cover being removably attachable to the opening portion and operable to expose a portion of the lower lid portion for accelerated cooling of the cooking chamber and speeding up wait time for opening the lid. Further, cooling towel or cooling pack can be placed at the opening portion to help with cooling and allow food to be enjoyed sooner.
