Abstract: A lens for a horn antenna and a horn antenna including the lens. The lens includes a generally flared plate assembly extending generally along an axis from a first side to a second side opposite the first side. The generally flared plate assembly defines a plurality of non-linear channels that are operable to manipulate an electromagnetic wave received at the first side to provide a manipulated electromagnetic wave at the second side.

Abstract: A modification method of an anode for hydrogen production via electrolysis, the anode for hydrogen production via electrolysis and use thereof are provided. The modification method of the anode for hydrogen production via electrolysis includes providing an anode substrate which can be used for hydrogen production via catalytic electrolysis; and depositing a plurality of silver nano particles on the active surface of the anode substrate to form a silver nano layer, wherein gaps are present between the silver nano particles, and a part of the active surface is exposed from the gaps. In the modification method provided by the present application, the silver nano layer covers on the surface of the anode substrate, and chlorine ions are adsorbed onto the surface of silver in the process of hydrogen production via electrolysis to form a chlorine removal layer.

Abstract: The invention discloses a method for manufacturing a new sound-absorbing and noise-reducing material by using polyimide foam scraps, cutting and processing the scraps generated in the process of polyimide foam production into particles of different sizes, drying red iron oxide or black iron oxide or titanium dioxide as inorganic additive, and then using each component in parts by weight, putting the inorganic additive into the mixer, and then putting the polyimide foam particles of different sizes into the mixer to mix, injecting the curing agent into the mixer to continue mixing, and finally adding the catalyst into the mixer to continue mixing, putting the mixed material into the mold evenly to form the film, leaving it for 10 hours, opening the mold, taking out the product, removing the burrs, and cutting the product according to customer needs, and packing it in a carton for storage.

The FRP winding pipe is provided with circumferential fiber materials by taking the FRP pultrusion hollow profile as a membrane, and forms a composite pipe section with the FRP pultrusion hollow profile. The inner ring shape of the cross section of the FRP winding pipe is matched with the FRP pultrusion hollow profile. The FRP connecting device includes connecting plates, connecting bars, and connecting pins.

Abstract: A transparent projection screen and a manufacturing method. The transparent projection screen is for receiving projection light and transmitting ambient light and comprises a first substrate layer, a Fresnel structure layer, a surface diffusion layer, a nano metal plating layer, and a binding adhesive layer. The Fresnel structure layer is disposed on the first substrate layer and comprises a prism surface. The surface diffusion layer is disposed on a portion of the prism surface. The nano metal plating layer is disposed on the surface diffusion layer. The binding adhesive layer is disposed on the nano metal plating layer and fills and levels the prism surface. The projection light passes the first substrate layer and is incident on the prism surface and then reflected thereby. The ambient light passes the binding adhesive layer, the nano metal plating layer, the surface diffusion layer and the first substrate layer, and is emitted.

Abstract: Improved electrochemical production of hydrogen peroxide is provided with a surface-oxidized carbon catalyst. The carbon can be, for example, carbon black or carbon nanotubes. The oxidation of the carbon can be performed, for example, by heating the carbon in nitric acid, or by heating the carbon in a base. The resulting carbon catalyst can have a distinctive oxygen is peak in its X-ray photoelectron spectrum.
