Atomization of metal and alloy powders: Processes, parameters, and properties
AIChE Journal, 2023Additive manufacturing (AM) has been intensively studied over this decade due to the increasing demand of functional and precise materials in various industries. AM process leverages on the concept of layer by layer deposition or joining of a material at

Study on atomization particle size characteristics of two-phase flow nozzle
Journal of Intelligent & Fuzzy Systems, 2021Nozzle spray atomization is widely used in industrial and agricultural production processes and is a very complicated physical change. The spray atomization of the nozzle is a process in which the droplets are continuously broken into finer particles ...

Angewandte Chemie, 2018
The arrangement of the active sites on the surface of a catalysts can reduce the problem of mass transfer and enhance the atom economy. Herein, supported Ni metal nanoparticles can be transformed to thermal stable Ni single atoms, mostly located on the ...

Atomic Spectrometry Update–Atomic mass spectrometry
Journal of Analytical Atomic Spectrometry, 1996The MS and XRF updates have been published together since their introduction in 1988. In the last few years, however, the two sections have been prepared independently of each other and it therefore seemed appropriate to publish the two sections separately.

AbstractMit Hilfe der Spitze eines Rastertunnelmikroskops wird ein einzelnes metallfreies Phthalocyanin‐Molekül in ein Silber‐Phthalocynanin auf einer Obefläche umgewandelt. Die Reaktionsschritte erfolgen Atom für Atom. Jedes Zwischenprodukt kann mit Hilfe von rastertunnelmikroskopischen Aufnahmen analysiert werden.

The effect of nozzle internal flow on spray atomization
International Journal of Engine Research, 2020The effect of nozzle surface features on the overall atomization behavior of a liquid jet is analyzed in the present computational work by adopting three representative geometries, namely a single X-ray tomography scan of the Engine Combustion Network’s ...

Reports on Progress in Physics, 2014
Atomic manipulation using a scanning tunneling microscope (STM) tip enables the construction of quantum structures on an atom-by-atom basis, as well as the investigation of the electronic and dynamical properties of individual atoms on a one-atom-at-a-time basis.
