TL;DR: This work investigates the transition from the metallic to molecular state in metal nanoparticles by performing ultrafast spectroscopic studies on atomically precise thiolate-protected Au25, Au38, Au144, Au333, Au∼520 and Au ∼940 nanoparticles.

TL;DR: Time-dependent mass spectrometry and optical spectroscopy analyses unambiguously map out the detailed size-conversion pathway and the number of ligands is interestingly preserved in the disproportionation mechanism identified in the transformation of rod-like biicosahedral Au38(SCH2CH2Ph)24 to tetrahedral Au36(TBBT)24 nanoclusters.

TL;DR: This new methodology (i.e., ligand-exchange-induced size/structure transformation, LEIST for short) has not only demonstrated the important role of thiolate ligand in the transformation chemistry of clusters but also paved the way for creating an expanded "library" of Aun(SR)m nanoclusters for exploration of their magic sizes, structures, properties, and applications.

TL;DR: All electrochemical CO2 conversion systems will produce a net increase in CO2 emissions if they do not integrate with renewable-energy sources, catalyst loading vs activity trends can be used to tune process rates and product distributions, and state-of-the-art renewable- energy technologies are sufficient to power larger-scale, tonne per day CO2 Conversion systems.

TL;DR: A ligand-based strategy for controlling nanocluster structure is demonstrated and a method for the discovery of possibly overlooked clusters because of their anomalous solubility is provided.
