Aluminum, although not many know it, is a metal with extraordinary properties. It does not exist in nature in the metallic state, but always in the form of compounds, the best known of which is Bauxite, in which it is contained in the form of oxides and hydroxides.
Absolute emptiness is the absence of matter in space. How many particles are present in the small UHV chambers used in laboratories? We asked ourselves this question in this article!
In pumping systems for vacuum plants,, it is common to use rotary vane pumps. In these machines, the oil has important functions for the correct functioning of the machine.
The management of the "water load" in vacuum processing always represents a problem due to the molecular composition of the water. The use of cryogenic systems can help the elimination of the water present in vacuum deposition systems.
Vaccum processing needs the presencence of a particular environment. But why is a reduced pressure environment necessary and what are the pressures used in the vacuum technique? This are the reasons.
If you have ever seen a machine for vacuum treatments, you will have noticed that the chamber in which the processing is carried out and a large part of the rest of the plant was made of stainless steel. But why, in these particular scientific and technological applications, is this material used? What are the advantages it offers (and what are the possible disadvantages)?
Magnetron sputtering has developed rapidly over the last twenty years, following the increasing industrial demand for high-quality functional films. Today, magnetron sputtering often outperforms other techniques used for the deposition of coatings of industrial interest.
A brief description about how thin films have found application in everyday life.
Thin film coatings has found applications in mirrors, microscopy, photo catalysis, photovoltaic, solar cells, switches, lenses, microelectronics, etc.Optical thin films involves the interaction of electromagnetic radiation, at different wavelengths, with a deposited functional layer.
Wide set of processes which are used by industry to deposit thin films, with a wide range of compositions and purposes, over substrate with largely variable composition, taking advantage of a high-vacuum environment.
