Abstract: An in-situ hydrophobically modified aramid nano aerogel fiber as well as a preparation method and uses thereof are provided. The preparation method includes: providing an aramid nano spinning solution; preparing a hydrophobically modified aramid nano aerogel fiber by using a spinning technology, wherein the coagulating bath adopted by the spinning technology includes a first organic solvent and a halogenated reagent including a monochloroalkane, a monochloroalkane, a dibromoalkane, a dichloroalkane and a trichloroalkane; and then drying to obtain the in-situ hydrophobically modified aramid nano aerogel fiber. The in-situ hydrophobically modified aramid nano aerogel fiber has a unique three-dimensional porous network structure, low heat conductivity, high porosity, high tensile strength and elongation at break, a certain spinnability and structure stability, and can be applied to the field of textiles. A fabric knitted with the hydrophobic fibers has a self-cleaning ability.

Abstract: A method for making a semiconductor substrate includes: cutting an ingot to obtain a plurality of substrates, each of the substrates including a first surface and a second surface opposite to the first surface; performing a surface treatment on at least one of the first surface and the second surface of each of the substrates using a surface-treating agent; annealing the substrates; and abrasing each of the annealed substrates. A method for making a semiconductor device is also disclosed.

Abstract: A method and apparatus for obtaining partial content of a webpage and a method and apparatus for sharing partial content of a webpage. An image of an area on the webpage selected by a user is captured. Linkable elements existing in the area and positions of respective linkable elements in the area are acquired. A HTML fragment is generated based on the image, the linkable elements and their positions in the area as the obtained partial content of the webpage. By virtue of the method and apparatus, Only interested partial content of the webpage can be shared by sharers, and receivers can not only view the partial content of the webpage exactly same with what the sharers view, but also access hyperlinks on this partial content of the webpage directly in a web browser.
