This eliminates the risk of intergranular corrosion that occurs after general heat treatment and welding. Due to its high chromium nickel molybdenum content and the addition of copper, 904L can be passivated even in reducing environments such as sulfuric acid and formic acid. ...
Here are the primary materials commonly utilized in the construction of bipolar hip prostheses: Metal Alloys: The femoral stem and outer shell of the prosthesis are often fashioned from metal alloys such as titanium, cobalt-chromium, or stainless steel. These alloys provide the necessary strength, durability, and stability to the implant. ...
Most concrete contains small amounts of hexavalent chromium which can cause an irritating to painful allergic skin condition called sensitization. ...
Large variations of metal accumulation levels in the oysters were documented, especially for copper (Cu), zinc (Zn), cadmium (Cd), chromium, and nickel (Ni). Among these metals, the authors demonstrated significant correlations between the digestive gland metal accumulation of Cu, Zn, and Ni and the cellular homeostasis (alkaline phosphatase) and glycogen reserves. ...
Tobacco can easily accumulate certain heavy metals in leaves and thus poses a potential threat to human health. To systematically dissect Cr-responsive miRNAs and their targets at the global level, four small RNA libraries were constructed from the roots of Cr-treated (Cr) and Cr-free (control) two contrasting tobacco genotypes,Yunyan2 (Cr-sensitive) and Guiyan1 (Cr-tolerant). Using ...
Concentrations of arsenic, barium, chromium, nickel, strontium, vanadium, and zinc in claws and skin biopsies were substantially elevated when compared to all other tissues, indicating that these highly keratinized tissues may represent sequestration or excretion pathways. ...
This paper describes the performance of diamond coated molybdenum dental burs machining orthodontic bridge such as cobalt-chromium alloys, and also portrays an interesting picture of how these alloys react to machining with diamond using a finite element method.Keywords: chemical vapour deposition, hot filament CVD, molybdenum, negative biasing, dental tools, orthodontic ...
