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: The present invention relates to a method of precipitation of metal ions. Mineral(s), oxide(s), hydroxide(s) of magnesium and/or calcium are adopted as raw materials, and the raw material(s) is processed through at least one step of calcination, slaking, or carbonization to produce aqueous solution(s) of magnesium bicarbonate and/or calcium bicarbonate, and then the solution(s) is used as precipitant(s) to deposit rare earth, such as nickel, cobalt, iron, aluminum, gallium, indium, manganese, cadmium, zirconium, hafnium, strontium, barium, copper and zinc ions. And at least one of metal carbonates, hydroxides or basic carbonates is obtained, or furthermore the obtained products are calcined to produce metal oxides. The invention takes the cheap calcium and/or magnesium minerals or their oxides, hydroxides with low purity as raw materials to instead common precipitants such as ammonium bicarbonate and sodium carbonate etc.

Abstract: The invention relates to a method and device for orienting magnetisable particles (4) in a kneadable material (3), in particular steel fibres or rings in unhardened concrete by means of an orienting body (1) provided with a non-magnetic wall comprising a front face section (1a) and a rear face section (1b). A kneadable material (33) and the front face section (1a) of the orientation body (1) are first and foremost displaced with respect to each other. The orientation body (1) is also provided with a magnetic unit (2) which is disposed on the internal side of said front face section (1a) and generates a periodically variable magnetic field acting on the kneadable material in order to orient the magnetisable particles (4). Said invention is characterised in that said magnetic field is divided into at least two areas (III) containing the partial fields exhibiting different forces and/or different directions of force lines.
