Metal-Catalysed Transfer Hydrogenation of Ketones
Topics in Current Chemistry, 2016We 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 ...

Significance of Metallic Transfer in Orthopædic Surgery
Nature, 1954IN an earlier communication1 attention was directed to the transfer of metal which can occur between a screwdriver tip and a screw head during the operation of screwing, and the possible significance this might have in orthopaedic surgery was discussed.

High-Yield Transfer Printing of Metal–Insulator–Metal Nanodiodes
ACS Nano, 2012Nanoscale 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.

A new theory of metal transfer and wear is suggested in this paper. The essence of the theory is as follows: Metal transfer and wear take place at points of actual contact. The interfaces of the high spots that actually make contact are roughened as the result of plastic deformation when they carry normal load.

Controlling the electron transfer mechanism in metal–molecules–metal junctions
Electrochimica Acta, 2005We show how the mechanism of electron transfer through molecules can be switched between different regimes by using Hg-based metal–molecules–metal junctions. The junctions are easy to assemble and allow for hosting of self-assembled monolayers (SAMs) of a large variety of molecular structures.

Heat Transfer in Liquid Metals
Journal of Fluids Engineering, 1958Abstract The problem of heat transfer in liquid metals is studied for the case of a fully developed turbulent flow in cylindrical pipes of constant diameter, the fluid under consideration being heated (or cooled) by a constant and uniform heat input at the wall. In the analysis, the similarity theory between heat and momentum transfer is

Electron transfer in the electrochemistry of metals, metal compounds and metal complexes
Inorganica Chimica Acta, 1994Abstract Because electron-transfer occurs at the electrode/solution interface, the oxidation of metal electrodes involves electron removal (within the interface) from a solvent molecule or basic constituent (ligand) rather than from the valence-electron shell of the metal .

Metal transfer in the sliding process
Wear, 1988Abstract Metal transfer, during mutual sliding of steel and aluminum alloys, was studied using a model experiment. The model imitated sliding conditions which occur in metalworking operations: high load and short sliding distances. It allowed access to the aluminum-steel contact area without breaking the contact.

Heat Transfer to Molten Metals
Journal of Fluids Engineering, 1947Abstract The contents of the paper are based on an extension of the analogy between heat and momentum transfer. Following the suggestion of von Kármán (9), the turbulent-flow field is divided into a laminar sublayer, a buffer layer, and a turbulent core.
