This template will self‐destruct : A unique particle‐growth mechanism involves growth of new coordination polymers on the surface of initially formed hexagonal blocks and concomitant dissolution of the blocks to form hexagonal tubes (see scheme and scanning electron, optical, and fluorescence microscopy images). Calcination of the tubes yields ZnO particles of the same shape.

Stable analogues : An effective synthetic route involving cycloaddition between alkynes and azidonucleosides to afford a new class of stable aminoacyl‐tRNA analogues such as depicted is presented. Biological evaluation showed that theses new compounds act as potent inhibitors of FemXWv aminoacyl transferase, a novel drug target.

Studying growth : The diffusion‐controlled kinetic (DCK) model and the surface chemical thermodynamics (SCT) model have been successfully applied to interpret the nucleation and growth mechanism of CeF3 (see TEM images) and NaCeF4 nanocrystals, and may generally give light to the size‐control and morphology prediction of rare‐earth fluorides at the nanoscale level.

ReacTiO 2 ns for rings : Gold nanoparticles supported on TiO2 are used as a novel heterogeneous catalyst for the isomerization of epoxides to allylic alcohols by a concerted mechanism (see scheme). The reaction proceeds in high yields and the product selectivity is often remarkable.

When the truth stands on one leg : Arsenate coordinates at the water–goethite interface in a predominately monodentate fashion (see picture), a finding that impacts oxoanion bioavailability and challenges theories of mineral dissolution and surface complexation.

Bubbling up : Dissolution of CO2 bubbles in a suspension of colloidal particles chemically induces the assembly of particles on the surface of shrunken bubbles, and thus yields rapid continuous formation of a colloidal armor. This approach maintains the high colloidal stability of particles in bulk, has increased productivity, and allows the formation of bubbles with precisely controlled dimensions.
