TL;DR: In this paper, the authors used in situ electron microscopy to show how gold and silver nanocrystals nucleate from supersaturated aqueous solutions in three distinct steps: spinodal decomposition into solute-rich and solutepoor liquid phases, nucleation of amorphous nanoclusters within the metal-rich liquid phase, followed by crystallization of these amomorphous clusters.

TL;DR: Liquid TEM is used to follow the entire galvanic replacement of Ag nanocubes, finding experimental evidence that the Kirkendall effect is a key intermediate stage during hollowing, and providing insights into the structural transformations as a function of Au ion concentration, oxidation state of Au, and temperature.

TL;DR: A voltage threshold for permeation through a synthetic nanopore of dsDNA bound to a restriction enzyme that depends on the sequence is discovered and it may be possible to discriminate between two variants of the same gene (alleles) that differ in one base.

TL;DR: Preliminary results have shown that with careful control of the dimensions of the pore and the shape of the electric field, control of DNA translocation through the pores is possible and discrimination between different base pairs of DNA may be feasible.
