Amorphous materials, glass-ceramics and methods of making the same. Embodiments of the invention include abrasive particles. The abrasive particles can be incorporated into a variety of abrasive articles, including bonded abrasives, coated abrasives, nonwoven abrasives, and abrasive brushes.

The present invention relates to a technology for specific capture of single stranded target Polynucleotide by a complementary probe comprising one or more intercalator molecules. The method further involves removal of one or more types of bases in the single stranded target Polynucleotide prior to interaction with the complementary probe. This results in generation of one or more abasic sites which can interact with and / or into where the intercalator molecule can be inserted.

The invention provides silica-alumina-sodium oxide glass which is suitable for a low-temperature ion exchange process and is easy to melt. The glass is suitable for chemical tempering, and comprises the following compositions in percentage by weight: 55 to 60 percent of SiO2, 0.1 to 2.5 percent of B2O3, 11 to 16 percent of Al2O3, 14 to 17 percent of Na2O, 1 to 8 percent of K2O, 0 to 8 percent of ZrO, 0 to 5 percent of CaO, 0 to 5 percent of MgO, and 0 to 1 percent of Sb2O3. The invention, by reasonably setting the compositions, reduces the manufacturing difficulty of the glass, obviously reduces the melting temperature of the glass, and is favorable for reducing energy consumption and improving the rate of finished products of products; and under the conditions that the tempering temperature of the glass is between 380 and 500 DEG C and the tempering time is between 4 and 12 hours, the surface compressive stress of the glass can reach between 610 and 1,100MPa, the depth of a stress layer can reach between 31 and 80 mu m, and the glass is strengthened and has good shock resistance. The glass has higher wear resistance, and is suitable for protective glass materials of high-grade electronic display products such as mobile phones, PDA and the like.

Disclosed herein is a polymer comprising an amorphous syndiotactic rich polyolefin comprising greater than about 50 wt % C3-C40 alpha olefins and having about 50% to less than about 80% r dyads, based on the total number of r and m dyads present in the polymer; a heat of fusion of 10 joules / g or less according to the procedure described in ASTM E 794-85; and an ash content of 1 wt % or less. A functionalized amorphous syndiotactic rich polyolefin is also disclosed, along with methods to produce and a method to use the inventive polymer.
