Northwestern University, USA
Metal nanoparticles, supported on amorphous SiO2, form nanopores in the SiO2 when heated above 1,000 °C. In this paper, we show that this behavior is general to a variety of metals (Au, Ag, Cu, Pd, and Pt) and demonstrate a way to control the extent of entrenchment. Further, we propose a mechanism and explain that this entrenchment occurs due to the glass-transition exhibited by amorphous SiO2.

The synthesis of CdS magic-size clusters (MSCs), which exhibit a single sharp absorption peaking at ~ 361 nm, along with sharp band edge photoemission at ~ 377 nm and broad trap emission peaking at ~ 490 nm, is reported for the first time. We label them as MSC-361. For reaction products displaying two absorption peaks at 361 and 322 nm, we demonstrate that they do not evolve synchronously. Thus, the 322 nm peak is not a higher order electronic transition of MSC-361, but due to the presence of another ensemble, namely MSC-322.
