Abstract: A method comprises obtaining a virgin asphalt and obtaining an asphalt shingle waste. The asphalt shingle waste comprises 5 wt. % to 40 wt. % of asphalt based on the total weight of the asphalt shingle waste. The asphalt shingle waste comprises 60 wt. % to 95 wt. % of limestone, granules, and/or impurities based on the total weight of the asphalt shingle waste. The method comprises obtaining a phase modifier. The method comprises mixing the virgin asphalt, the asphalt shingle waste, and the phase modifier to form an asphalt mixture. The phase modifier is present in an amount of 0.25 wt. % to 25 wt. % based on the total weight of the asphalt mixture. The asphalt mixture is configured to be applied to a roof substrate to obtain a roofing shingle.

Abstract: A light-emitting device, a light-emitting substrate, and a method for manufacturing the light-emitting device. The light-emitting device includes at least one light-emitting structure. The light-emitting structure includes: a first semiconductor layer; a light-emitting layer; a second semiconductor layer, doping ions of the second semiconductor layer and a first semiconductor layer being oppositely charged; a barrier structure provided with an opening for exposing the second semiconductor layer, the orthographic projection of the opening on the base substrate being located in the orthographic projection of the light-emitting layer on the base substrate, and the area of the opening being smaller than that of the light-emitting layer; and a landing electrode located on the side of the barrier structure facing away from the second semiconductor layer, the landing electrode being in contact with the second semiconductor layer by means of the opening.

Abstract: Various implementations of systems, devices, and methods to connect an electrical power source safely to an electrical end user household mains grid installation. In an exemplary implementation, a solar energy module is connected to a typical mains power outlet wall socket using a mains power plug. Potentially live male-shaped connectors of the mains power plug are, for example, isolated and/or disconnected from the electrical power source so that the male-shaped connectors of the unplugged mains power plug are safe for users and bystanders even if the power source produces electrical energy and, therefore, the mains power plug is at least partially live.

Abstract: A method for preparing an oxygen-free passivated titanium or titanium-alloy powder product by means of gas-solid fluidization is provided.

Abstract: A core drill assembly includes a core drill and a stand upon which the core drill is mounted. The stand includes a base supportable upon a mounting surface, a mast defining a longitudinal axis and extending upward from the base, a carriage moveably coupled to the mast and configured to support the core drill thereon, and at least one leg pivotably coupled to the base between a deployed position, in which the leg extends away from the base, and a stowed position, in which the leg is at least partially recessed within the base.

Abstract: A high-strength confined concrete support system for an underground tunnel. The support system includes multiple confined concrete arches, bolts and cables, and a prestressed steel strand backfilling system. The confined concrete arches all support the surrounding rock of the tunnel and are sequentially arranged along the tunnel. Every two adjacent confined concrete arches are connected by a longitudinal connection structure. The support system is provided with a plurality of layers of steel bar meshes on the surrounding rock side and the tunnel side, and shotcrete layers are sprayed on the support system and the steel bar meshes. The prestressed steel strand backfilling system comprises a prestressed steel strand system and a filling material. The filling material fills the space between each confined concrete arch and the surrounding rock to equalize a load on the confined concrete arch and generate prestress.
