Abstract: The present invention provides a hydrophilic/oleophobic sponge, a preparation method and use thereof, and belongs to the technical field of functional material preparation. In the present invention, a modified solution is obtained by mixing a nanoparticle suspension with a modifier solution; the nanoparticle suspension includes silica-encapsulated Fe3O4 nanoparticle suspension and/or nano-silica ethanol suspension; the modifier solution includes chitosan-acetic acid aqueous solution and polyvinyl alcohol (PVA) aqueous solution. The sponge is soaked in the modified solution, mixed and crosslinked with glutaraldehyde aqueous solution to obtain the hydrophilic/oleophobic sponge, conferring good oil-water separation ability on the sponge. The sponge effectively separates a heavy water layer from oil-water mixtures with such light oils as lubricating oil, engine oil, pump oil, crude oil, gasoline, and sunflower seed oil in a simple gravity-driven manner.

Abstract: A method for preparing a carbon-coated ternary positive electrode material has steps of preparing a ternary positive electrode material precursor, and preparing a suspension of the ternary positive electrode material precursor. Lithium acrylate is added to the suspension of the ternary positive electrode material precursor according to the molar ratio of Li:(Ni+Co+Mn) being 1.03-1.05:1. Ammonium persulphate is added to the lithium acrylate-containing suspension of the ternary positive electrode material precursor, so that the lithium acrylate undergoes a polymerisation reaction and a suspension of a lithium polyacrylate-coated ternary positive electrode material precursor is obtained. The suspension of the lithium polyacrylate-coated ternary positive electrode material precursor is dried to obtain spherical particles. The lithium polyacrylate-coated ternary positive electrode material precursor particles are sintered to obtain a carbon-coated ternary positive electrode material.

Abstract: A machine-learning system receives from multiple sensors a set of trace-data time series. Each time series contains a chronological sequence of sensor measurements of one attribute of one instance of a manufacturing product or process. The system partitions each series into a set of contiguous segments and selects one received series to be a standard series for each attribute. The starting and ending measurements of each non-standard time series are then time-aligned to the starting and ending points of the non-standard series' corresponding standard series, using a dynamic time-warping procedure. One or more segments of each aligned non-standard series are then aligned to each segment of the corresponding standard series. The resulting time-aligned, segmented time series are then incorporated into a corpus that is used by a machine-learning module to train a self-learning application.
