Transfer of electrons on scratched iron surfaces: Photoelectron emission and X-ray photoelectron spectroscopy studies

We report the activation energy, ΔE a, for the quantum yield in thermally assisted photoelectron emission (TAPE) under 210-nm-wavelength light irradiation, and the associated X-ray photoelectron spectroscopy (XPS) results. Samples were cleaned …

Tribological evaluation of environmentally friendly ionic liquids derived from renewable biomaterials

Unlike most of the conventional ionic liquids (ILs) derived from non-renewable resources, five environmentally friendly ILs ([Ch][AA] ILs) derived from amino acids (AAs) and choline (Ch) were synthesized using biomaterials by a simple, green …

Synchronous measurement of tribocharge and force at the footpads of freely moving animals

Hypothesis on electrostatic attraction mechanisms involving the hairy adhesion of climbing animals has been a matter of controversy for several years. The detection of tribocharge and forces at attachment organs of animals is a practical method of …

Thermocapillary migration mechanism of molten silicon droplets on horizontal solid surfaces

Effective lubrication under extreme conditions such as high temperature is of considerable importance to ensure the reliability of a mechanical system. New lubricants that can endure high temperatures should be studied and employed as alternatives …

Study on the influence of standoff distance on substrate damage under an abrasive water jet process by molecular dynamics simulation

The process of a cluster-containing water jet impinging on a monocrystalline silicon substrate was studied by molecular dynamics simulation. The results show that as the standoff distance increases, the jet will gradually diverge. As a result, the …

Industrie 4.0 und die Möglichkeiten des Digitalen Zwillings

Die Welt der industriellen Automatisierung erlebt gerade einen bedeutenden Umbruch – hin zur Industrie 4.0. Der Ansatz, Dinge zu bauen und danach irgendwie hinzubiegen, hat viel zu lange die Entwicklung neuer Projekte bestimmt. Stattdessen brauchen die Hersteller einen systemorientierten Ansatz, der sich bereits in Entwicklungsprozessen multidisziplinärer Systeme bewährt hat. Jetzt gratis downloaden!
