A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces. The glass composite has a light transmittance not lower than 95% of the light transmittance of the one, with the lower light transmittance, of the first glass member and the second glass member.

A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces, and a contact interface is formed on the contacting position of the first glass member and the second glass member. The contact interface is visually observed to have no crevices; and when the glass composite is in contact with an acid solution, crevices are suitably formed in the glass composite at the contact interface.

A filler material is applied to a plurality of wood elements. The plurality of wood elements is bonded into a composite wood product, where the bonding includes delivering ultrasound energy to the plurality of wood elements. The ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz.

A method for producing a composite component including a bottom layer, cover layer and honeycomb structure, including applying the honeycomb structure to the bottom layer wherein honeycomb chambers are formed. Honeycomb chambers are filled in a reinforcement region with a granular material and granular material is removed from other honeycomb chambers wherein each honeycomb chamber is filled up to a granular-material filling height and honeycomb chambers outside the reinforcement region are free of granular material. The cover layer is applied to the honeycomb structure wherein the honeycomb chambers are closed. The composite component is heated so the granular material in the honeycomb chambers expands to fill it with granular material and the cover layer, the bottom layer, the honeycomb structure and the expanded granular material harden, the density of the expanded granular material in the honeycomb chambers filled with granular material being dependent on the granular-material filling height.

The present invention belongs to the technical field of energy conversion devices, which provides an rGO-PEI/PVDF pyroelectric thin film, and the method for preparing the film, as well as a self-energized bracelet produced based on such film, which utilizes the reduced graphite oxide after modified by polyethyleneimine (PEI) (rGO-PEI) as photothermal conversion material, and the silver-plated polarized polyvinylidene fluoride (PVDF) film as pyroelectric conversion material. The rGO-PEI photothermal material is fixed to the surface of the PVDF through a transparent film, and prepare the self-energized bracelet based on it. The obtained bracelet has an output power of up to 21.3 mW/m2, and does not require additional mechanical devices to control the temperature during operation, wherein, the thermoelectric conversion, rectification, storage and application are realized through temperature fluctuation produced by absorbing sunlight during doing outdoor sports, utilizing temperature difference of air flow, and sweeping gesture, etc.

A computer keyboard is refurbished by applying to its keys stickers each bearing a character designating the action of a respective key. For application of the stickers to the keys, the stickers are configured and arranged on an application tape in a layout congruent with the layout of the keys by a digital scan of the keyboard. The stickers are temporarily attached to the application tape by a peelable adhesive and then permanently attached to the keys by a pressure-sensitive permanent adhesive.

Described herein is a mirror apparatus comprising: a reflective substrate; and an anti-fog complex comprising: an adhesive layer atop the substrate; a first polymeric layer atop the pressure sensitive adhesive layer; and a second polymeric layer atop the first polymeric layer. Methods of making the mirror apparatus are also disclosed.

A method of manufacturing a structural arrangement on the basis of a fiber reinforced polymer component, comprising at least the steps of: providing a fiber reinforced polymer component; fixing a polyether sulfone foil on the fiber reinforced polymer component, at least in a region where an electrically conductive layer is to be formed; and performing a cold gas spraying process for spraying electrically conductive particles onto the polyether sulfone foil in order to create the electrically conductive layer.

A method of manufacturing a composite member including an aluminum member and a fiber-reinforced resin member bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water by using at least one of heat and plasma; and directly bonding the fiber-reinforced resin member to the surface of the aluminum member modified to the aluminum hydroxide.

A structural arrangement comprising a fiber reinforced polymer component, a cold gas spraying electrically conductive layer, and a polyether sulfone foil arranged on the fiber reinforced polymer component, at least in a region between the fiber reinforced polymer component and the cold gas sprayed electrically conductive layer.
