TL;DR: A linear relationship between the logarithms of extinction coefficients and core diameters of gold particles was found independent of the capping ligands on the particle surface and the solvents used to dissolve the nanoparticles, and may be used as a calibration curve to determine the concentration or average size of an unknown nanoparticle or nanoparticle-biomolecule conjugate sample.

TL;DR: In this article, the grain boundary energy is derived and systematically studied in terms of temperature, grain size, concentration and solute segregation for binary systems of 44 solvents and 52 solutes, using readily available elemental data, such as moduli and liquid enthalpy of mixing.

TL;DR: In this article, the mechanism of grain size stabilization was investigated using thermodynamic and kinetic modeling, and a good correlation between calculation and experimental observation was found by applying estimations for the limiting grain size and Orowan strengthening via second-phase pinning.

TL;DR: In this paper, tungsten (W) was added in a high-energy ball mill to stabilize the Cu at ∼40nm during annealing to 400°C for a 1-at-tungsten composition and to 600¼C for 10-at% W. The added W provided a significant increase in strength over pure Cu and maintained a 2.6-GPa hardness after annaling at 800°C.

TL;DR: The recombination of small particles into larger ones was found to follow a logistic model, as confirmed by a nonlinear regression fitting of the UV-Vis absorption data of the reaction solution with the mathematical model.
