Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond
Advanced Materials, EarlyView.Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Stellar Multiplicity Discovery by Lunar Occultations [PDF]
International Astronomical Union Colloquium, 1992 AbstractThe primary result of lunar occultation studies of multiple star systems is the discovery of new systems. Its use as a method of multiplicity discovery has been productive, although incidental to timing observations made by amateurs and professionals for 360 years.

Advanced Materials, EarlyView.Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

The Detection of Stellar Systems by Lunar Occultations [PDF]
International Astronomical Union Colloquium, 1977 AbstractA few examples of the resolution of very close multiple stars by the method of lunar occultation are described. In this way both the power and some of the limitations of this technique may be demonstrated.
