The titanium dioxide layers are deposited on the surface of the polypropylene porous film substrate by atomic deposition technology; a surface modifier is coated on the titanium dioxide layers; hydrophobic bonds are formed between the titanium dioxide layers and the surface modifier layer; the superhydrophobic polypropylene porous film has a water contact angle greater than 150 degrees, a rolling angle less than 10 degrees, an aperture of 0.1-0.4 ?m, a porosity of 50%-80%, a tensile strength of 30-50 MPa, and an elongation at break of 10%-30%.

Abstract: A large-particle spherical salt with a particle size of 400-950 ?m and a sphericity of 0.5-1.0 is disclosed, which overcomes the existing difficulty in this field for larger particle size as well as higher sphericity. A preparation method of the large-particle spherical salt is also disclosed, wherein in one preparation process, 2% of gum arabic (based on the mass percentage of solute sodium chloride in a sodium chloride saturated solution) is added, and under conditions of an evaporating temperature of 60° C. a stirring rate of 350 rpm, and an evaporating time of 8 hours, a large-particle spherical salt with a particle size of 921.593 ?m and an average sphericity of 0.904 is successfully prepared. The large-particle spherical salt prepared by the method has a uniform particle size distribution and good appearance, can be combined with other substances, adding some extra value to the salt. Meanwhile, the large-particle spherical salt prepared by the method has a high safety grade (e.g.

Abstract: A system may provide a toolbar in a browser at a client, where the toolbar permits user selection from multiple different services for sharing document content. The system may receive a selection of a first one of the multiple different services from a user via the toolbar and may receive a selection of content of a first document browsed by the user. The system may post the selected content in a second document associated with the first one of the multiple different services.

Abstract: One or more server devices may simultaneously calculate first ranking scores for a group of users and second ranking scores for a group of comments authored by the group of users. The calculating may occur during a same process. The one or more server devices may further provide one of a first ranked list that includes information identifying the group of users, the information identifying the group of users being ordered based on the first ranking scores, or a second group of comments of the group of comments, the comments in the second group of comments being ordered based on the second ranking scores.

Abstract: One or more server devices may receive an indication that a particular user has accessed a particular document. The one or more server devices may determine whether the particular document has been flagged as needing comments, and retrieve an author likelihood score for the particular user when the particular document has been flagged as needing comment. The one or more server devices may determine whether the retrieved author likelihood score is greater than a particular threshold, and provide a suggestion to the user to write a comment about the particular document when the author likelihood score is greater than the particular threshold.
