Laser-assisted inkjet printing of highly viscous fluids with sub-nozzle resolution

Demetri Psaltis, Christophe Moser, Paul Delrot, Miguel Antonio Modestino

Drop-on-demand inkjet printing is mostly based on thermal and piezo-actuation, allowing for densely packed nozzles in inkjet printers. However, the droplet diameter is typically defined by the nozzle diameter, thus limiting the range of viscosity that can ...

CS2 activation at uranium(III) siloxide ate complexes: the effect of a Lewis acidic site

Marinella Mazzanti, Julie Renée Michelle Andrez

Multimetallic cooperative binding of heteroallenes provides an attractive route to their activation, but the reduction of CS2 at heterobimetallic sites, associating an electron-rich metal with a main group Lewis acid has not been explored. Here we show tha ...

Self-Assembly of Arylboronate Esters with Pyridyl Side Chains

Rosario Scopelliti, Kay Severin, Erin Sheepwash, Kai Zhou

Boronate esters that contain N-donor groups are self-complementary structures, which can assemble by means of dative boron–nitrogen bonds to form macrocycles or polymers. Herein, we describe the synthesis of dioxaborinanes and benzodioxaboroles containing ...
