Can microbes be used to preserve archaeological iron objects? Lucrezia Comensolia, J. Maillardb, P. Juniera and E. Josepha,c a Laboratory of Microbiology, Institute of Biology University of Neuchâtel, Switzerland b Laboratory for Environmental Biotechnolog ...
The corrosion behaviour and the wear ranking of biomedical high carbon (HC) and low carbon (LC) CoCrMo alloys sliding against an alumina ball in four different simulated body fluids [NaCl and phosphate buffered solutions (PBS) with and without albumin] has ...
In the present study, a forged CoCrMo (ISO 5832-12) has been subjected to pulsed plasma treatment in a N-2/H-2 atmosphere at low temperatures (below 500 A degrees C). This treatment resulted in the formation of a layer composed by dispersed chromium nitrid ...
The chemical-mechanical polishing process (CMP) is an essential part of the production of integrated circuits. Metal to be polished in the CMP reacts with the oxidants from the aqueous suspension (slurry) and the passive film is formed on the metal surface ...
Al-Cr-Fe complex metallic alloys are new intermetallic phases with low surface energy, low friction, and high corrosion resistance down to very low pH values (0-2). Flow microcapillary plasma mass spectrometry under potentiostatic control was used to chara ...
Self-assembled monolayer (SAM) films have attracted immense attention for both fundamental and applied research. A SAM is composed of a large number of molecules with a head group that chemisorbs onto a substrate, a tail group that interacts with the outer ...
The effect of body fluids inorganic species on element-specific dissolution of a Mg-Y-Rare earth elements (RE) alloy was investigated by flow microcapillary plasma mass spectrometry. A new important aspect of this method is the online monitoring of precipi ...
Electrochemical and friction measurements during unidirectional sliding tests are used to monitor and to evaluate the tribocorrosion behavior of a passivating material. Tribocorrosion is the interplay between chemical, electrochemical, and mechanical proce ...
The determination of polar organic contaminants (pesticides, pharmaceuticals and inhibitors of corrosion) in river water was carried out using POCIS as a passive sampling technique and UPLC-MS/MS as a determination technique. Several compounds with propert ...
Investigation of the microstructure, properties and biocompatibility of the Ti-6Al-4V alloy nitrided under glow discharge was performed. The microstructural analyses were carried out using light microscopy, X-ray diffraction, analytical scanning and transm ...
