Bn/Sn−1 B n / S n − 1 is a compact Hausdorff space X X with a point p p (the class of the collapsed Sn−1 S n − 1) such that X ∖ is homeomorphic to Bn ∖Sn−1 B n ∖ S n − 1, which is the open n n -ball Un U. This is one intuitive way to arrive at these equations. In general, doping with heteroatoms leads to the redistribution of the electronic and functional group structures of the. 3 (b)) showed that atomic contents of B, N, S, and P were 1.93, 3.87, 2.41, and 6.29 %, respectively, and all heteroatoms have been uniformly doped into the N-C structure. The calculations obtained by spectral fitting (Fig. ![]() The people who built BNSF were - and continue to be - a unique breed, blending. While many different railroads combined to form BNSF, the people who worked at those railroads shared many traits. ![]() Today's BNSF Railway is the product of nearly 400 different railroad lines that merged or were acquired over the course of 170 years. The obtained B,N,S-CDs are found to be responsive to the pH changes, i.e., the fluorescence intensities obviously change with the watershed of pH 7.4, accompanied by a blue-shift of the fluorescence emission wavelengths with the pH from 1 to 13. Novel red-emitting B, N, S-co-doped carbon dots (B,N,S-CDs) were prepared via a one-step hydrothermal carbonization.B&N MasterCard Free Premium Membership Offer.
