Abstract: A charging system includes at least one first charging device and at least one second charging device that are cascaded. The first charging device includes at least one first accommodation portion for mounting a first energy storage device and a connecting port for connecting the second charging device or the first charging device. The second charging device includes at least one second accommodation portion for mounting a second energy storage device and a connecting port for connecting the first charging device or the second charging device. The first accommodation portion and the second accommodation portion have different shapes or dimensions.

Abstract: A seismic quantitative prediction method for shale total organic carbon (TOC) based on sensitive parameter volumes is as follows. A target stratum for a TOC content to be measured is determined, logging curves with high correlations with TOC contents are analyzed, the logging curves are found as sensitive parameters; sample data are constructed using the sensitive parameters; a radial basis function (RBF) neural network is trained with the sample data as an input and the TOC content at a depth corresponding to the sample data as an output to obtain a RBF neural network prediction model; sensitive parameter volumes are obtained by using the sensitive parameters and post stack three-dimension seismic data to invert; prediction samples are constructed using the sensitive parameter volumes; the predicted samples are input to the RBF neural network prediction model to calculate corresponding TOC values, thereby the TOC content of the target stratum is predicted.

Abstract: A haircare appliance has a heater housing, a heater assembly disposed in the heater housing, a circuitry housing remote from the heater housing, and an electronic component disposed in the circuitry housing. The haircare appliance has an electrical cable extending from the circuitry housing to the heater housing, a wire disposed within the electrical cable, the wire connecting the electronic component to the heater assembly, and an attachment member attaching the electrical cable to the circuitry housing. The attachment member has a main body having a bore within which the electrical cable is held. The attachment member has first and second arms extending from the main body, the first arm engaged with a first side of the circuitry housing, and the second arm engaged with a second side of the circuitry housing. The second side of the circuitry housing is opposite to the first side of the circuitry housing.

Abstract: Some embodiments of the disclosure provide a nano-catalyst composite for decomposing formaldehyde at room temperature and a preparation method. According to an embodiment, a nano-catalyst composite includes an alumina carrier of a nano dual-via structure. An inner part and a surface of the nano-alumina dual-via structure are loaded with a non-stoichiometric nano-metal manganese dioxide (MnO2-x) catalyst. According to another embodiment, a preparation method of a nano-catalyst composite for decomposing formaldehyde at room temperature includes the following steps. (1) Loading manganese dioxide onto the nano-alumina carrier by an electron beam thermal evaporation technology. (2) Conducting hydrogenation treatment on the manganese dioxide catalyst on the nano-alumina carrier under a condition of specific hydrogen pressure, specific temperature, and a specific hydrogenation time, to obtain the non-stoichiometric nano manganese dioxide (MnO2-x) catalyst.
