TL;DR: In this article, the extinction coefficient per mole of nanocrystals at the first exitonic absorption peak, e.g., for high-quality CdTe, CdSe, and CdS, was found to be strongly dependent on the size of the nanocrystal, between a square and a cubic dependence.

TL;DR: In this paper, it was shown that a "nanofluid" consisting of copper nanometer-sized particles dispersed in ethylene glycol has a much higher effective thermal conductivity than either pure or pure glycol or even polyethylene glycol containing the same volume fraction of dispersed oxide nanoparticles.

TL;DR: It is shown that noncoordinating solvents not only are compatible with the synthesis of semiconductor nanocrystals, but also provide tunable reactivity of the monomers by simply varying the concentration of ligands in the solution.

TL;DR: Using the high specific surface area of Fe3O4 NCs that were 12 nanometers in diameter, the mass of waste associated with arsenic removal from water was reduced by orders of magnitude and the size dependence of magnetic separation permitted mixtures of 4- and 12-nanometer–sized Fe3Os to be separated by the application of different magnetic fields.

TL;DR: In this article, the formation of nearly monodisperse CdTe nanocrystals was studied, and the ligand effects on the monomers were found to play a more important role than ligand effect on the nanocrystal and the bonding strength and steric effects of ligands dramatically affect the reactivity of monomers and are considered as contributors to the activity coefficients of monomer.
