Abstract: The present application discloses an air conditioner control method. The method includes obtaining a position of a user; detecting that the position of the user meets a preset condition, and obtaining a target operating parameter of an air conditioner, the preset condition being determined according to a preset running time span, and the preset running time span being determined according to a current environmental parameter and a target environmental parameter, and the current environmental parameter comprising at least one of a current indoor temperature, a current indoor humidity, a current air cleanliness and a current air freshness; and controlling the air conditioner at a target position to operate with the target operating parameter. The present application also discloses an air conditioner, a server and a computer readable storage medium.

Abstract: An energy-saving control method includes obtaining a demand instruction configured to indicate an energy-saving operation and a performing time slot of the energy-saving operation. The energy-saving operation is determined based on load data of a power grid and is configured to reduce a load of the power grid. The method further includes transmitting a first control message configured to control an authorized device to perform the energy-saving operation in response to detecting that time reaches the performing time slot, and transmitting a second control message configured to control the authorized device to stop performing the energy-saving operation in response to detecting that time is outside the performing time slot.

The active layer includes a carrier and a nanocomposite material formed on the carrier, and the nanocomposite material is antibacterial, antiviral and can decompose organics. The multifunctional mask includes at least one PTFE layer, at least one active layer and a skin-friendly layer. The multifunctional cloth and the multifunctional mask can further include a water-repellent layer.

Abstract: Disclosed is a liquid-phase oxidative decomposition method for radioactively contaminated carbonaceous material, providing a method of oxidizing carbon into a gas in liquid phase to treat radioactively contaminated carbonaceous material. The method comprises the following steps: ball milling a mixture of a molybdenum-containing substance and a carbonaceous material, thermally treating the ball milled mixture, and performing liquid-phase oxidation of the thermally treated mixture. The thermal treatment causes carbon to enter space between molybdenum atoms so as to reduce the particle size of carbon and improve the chemical reactivity of carbon, and an oxidant is then used to oxidize the carbon in the space between molybdenum atoms into a gas in liquid phase, while the molybdenum-containing moiety is converted into a water-soluble substance.
