    The real part of every nontrivial zero of the Riemann zeta function is 1/2. The Riemann hypothesis is that all nontrivial zeros of the analytical continuation of the Riemann zeta function have a real part of ⁠ 1 / 2 ⁠. A proof or disproof of this would have far-reaching implications in number theory, especially for the distribution of prime ...

    This statement, due to Tunnell's theorem (Tunnell 1983), is related to the fact that n is a congruent number if and only if the elliptic curve y 2 = x 3 − n 2 x has a rational point of infinite order (thus, under the Birch and Swinnerton-Dyer conjecture, its L-function has a zero at 1). The interest in this statement is that the condition is ...

    One of the efficient DSSCs devices uses ruthenium-based molecular dye, e.g. [Ru(4,4'-dicarboxy-2,2'-bipyridine) 2 (NCS) 2] (N3), that is bound to a photoanode via carboxylate moieties. The photoanode consists of 12 μm thick film of transparent 10–20 nm diameter TiO 2 nanoparticles covered with a 4 μm thick film of much larger (400 nm ...

    [2] [1] Thus, this process is indirect, since the final substrate does not pass through the printer, and the sublimation step occurs separately. The term direct dye sublimation is sometimes applied to a variant of digital textile printing using dye-sublimation inks printed directly onto fabric, which must then be heated to set the dyes, without ...
