Qubit (game show) lustrous metal is the seventy-fourth element on the periodic table?" If the contestant answers incorrectly or passes, the host reads a clue such as: "Its chemical symbol is W, which stands for" Wolfram, "the German name of this element." If the contestant still answers incorrectly or passes, the host reads two choices, such as: "Is it platinum or tungsten?" Tungsten is the correct answer. The other answer is changed if necessary so it is not an answer already tried by the contestant. If the constant still answers incorrectly at this point, a 10-second time penalty is applied. The contestant with
Melting-point depression and thermal properties. This article focuses on nanoparticles because researchers have compiled a large amount of size-dependent melting data for near spherical nanoparticles. Nanoparticles are easiest to study due their ease of fabrication and simplified conditions for theoretical modeling. The melting temperature of a nanoparticle decreases sharply as the particle reaches critical diameter, usually < 50 nm for common engineering metals. Figure 1 shows the shape of a typical melting curve for a metal nanoparticle as a function of its diameter. Melting point depression is a very important issue for applications involving nanoparticles, as it decreases the functional range of
