The subject application relates to bonded abrasive with low wetting bond material. An abrasive article including a bonded abrasive body having a particular MOR/EMOD ratio associated with a particular bond vol %. The body also can include a) an average Bond Post Area (BPA) of not greater than microns; b) an average Bond Post Count (BPC) of at least 140 per 1536 mm; c) an average bond wetting radius of at least 30/microns; or d) a combination of a) and b).

Bonded abrasive with low wetting bond material

Provided are a fusion protein and use thereof. Provided is a fusion protein, comprising a trimerization block and an immunogenic block which are connected by a linker, wherein the trimerization block comprises one or more of repeat units set forth in SEQ ID NO. 1; the immunogenic block is an immunogenic protein of a pathogen, for example, being selected from a coronavirus RBD block, an HIV membrane protein or an influenza virus hemagglutinin protein, and immunogenic fragments thereof. Compared with an immunogen monomer, the trimer can generate a higher neutralizing antibody level, does not induce a strong antibody against the trimerization block in a human body, and can promote the immune response of the organism to be focused on the immunogenic block.

Fusion protein and use thereof

An abrasive article can include a body including abrasive particles contained in the body and ceramic particles contained within a bond material. The ceramic particles can have an average particle size D50c of at least 2 microns and at most 75 microns. The abrasive particles can include an average particle size D50a greater than the average particle size D50c.
