Abstract: A dual-modal information storage and anti-counterfeiting material, and its preparation method are provided. The dual-modal information storage and anti-counterfeiting material uses cadmium sulfide quantum dots (CdS QDs) as information storage material, and uses the controllable photocorrosion of CdS QDs to achieve dual-modal optical information storage and anti-counterfeiting applications. Firstly, the type of ligands and modification degree of CdS QDs are precisely controlled during the aqueous phase synthesise process, so as to effectively control the photocorrosion phenomenon under UV light irradiation. Subsequently, the CdS QDs are loaded in the hydrogel network, and they are also loaded on the substrates such as cloth and paper by spray coating, dip coating or 3D printing, and the information is stored by digital light patterning. Different from the photochromic function of traditional anti-counterfeiting material, the CdS QDs shows dual-modal patterning characteristics in a wide wavelength range.

Abstract: Provided is a concave-plate triple eccentric butterfly valve, which includes a valve body, a upper valve stem, a valve seat, a valve plate, and a lower valve stem, among which the valve plate has a concave structure. When used in an isolation function application as well as in a fully open state, the valve plate is hidden behind the valve seat and the fluid passage of the valve is a smooth fluid passage, the valve can have a greater flow capacity. The flow of the fluid does not flush the valve plate sealing surface from the front. During the opening and closing process, the turbulence caused by the disturbance of the fluid is reduced and therefore the vibration of the system is reduced. In adjustment applications, the adjusting sleeve concave spherical surface, the adjusting sleeve fluid passage, and the valve plate convex spherical surface can cooperate to form the fluid passage adjusting opening.
