High-Yield Transfer Printing of Metal–Insulator–Metal Nanodiodes

ACS Nano, 2012
Nanoscale metal-insulator-metal (MIM) diodes represent important devices in the fields of electronic circuits, detectors, communication, and energy, as their cutoff frequencies may extend into the "gap" between the electronic microwave range and the optical long-wave infrared regime.

Photoinduced Ligand-to-Metal Charge Transfer in Base-Metal Catalysis

Synthesis, 2023
AbstractThe absorption of light by photosensitizers has been shown to offer novel reactive pathways through electronic excited state intermediates, complementing ground-state mechanisms. Such strategies have been applied in both photocatalysis and photoredox catalysis, driven by generating reactive intermediates from their long-lived excited states ...

Heat Transfer Characterization of Metallic Foams

Industrial & Engineering Chemistry Research, 2005
Gas−solid heat transfer coefficients were determined in open-celled metal foams as part of a study aimed at evaluating the application of metal foams as catalyst supports in gas−solid catalytic processes with short contact times and high reaction rates, typically controlled by diffusional mass transport.

Metal-Catalysed Transfer Hydrogenation of Ketones

Topics in Current Chemistry, 2016
We highlight recent developments of catalytic transfer hydrogenation of ketones promoted by transition metals, while placing it within its historical context. Since optically active secondary alcohols are important building blocks in fine chemicals synthesis, the focus of this review is devoted to chiral catalyst types which are capable of inducing ...

Helium II Transfer on Metal Surfaces

Nature, 1950
ONE of the most striking features of the film flow in liquid helium II is provided by the fact that the rate of transfer seems to be largely independent of the experimental conditions1. It was thought for some time that the rate was influenced by the geometrical shape of the transfer vessel, or by a temperature gradient in the film2, or by small ...

Metallic film transfer during metal-ceramic unlubricated sliding

Wear, 1989
Abstract The friction and wear characteristics of metallic materials in sliding contact with oxide ceramics were examined, using a pin-on-plate configuration and reciprocating motion. Friction was monitored continuously and wear rate was evaluated by microscopic measurements of worn pin scars.
