Prostheses made from ceramic materials have the advantages of producing little debris and having good durability, compared with those made from metal and plastic. For example, hip prostheses require a porous external area ...

Flax pulp was bleached by using an enzyme treatment with laccase (L stage) in the presence of HBT as mediator in order to replace chlorine-based pulp bleaching processes which produce toxic organochlorine compounds with ...

At present, laser cutting is currently employed to cut metallic plates, due to their good finish and dimensional quality, as well as because of the flexibility of the process to obtain different shapes. In the present ...

Hot torsion tests were carried out to simulate the industrial thermomechanical processing of two austenitic steels for bioimplant applications, namely ISO 5832-9 and ASTM F138. The former has Ti, Nb, and V in the composition, ...

Esta investigación analiza los efectos de un láser de pulsos de nanosegundos en las características del acero inoxidable AISI 301LN. El estudio pretende utilizar este material en una aplicación específica de almacenamiento ...

Aim of this paper is to analyze the effect of manganese percentages on steel compositions. Laboratory as cast materials, in particular designed for Quenching and Partitioning process (Q&P), are here considered. The ...

A closed expression for the autocorrelation of the far field noise due to random near field noise in a cylindrical near to far field transformation is derived. This expression is employed to obtain bounds for the computed ...

Among all ions present in a cardiac cell, calcium is categorically the most important. It governs the contraction and relaxation of the heart chambers that enables pumping of blood throughout the body. Calcium mishandling ...

This work investigates the activity of copper modified Ce0.50Zr0.50O2 (Cu-CZ) based anodes prepared through subsequent impregnation steps into a porous YSZ matrix. The ceria zirconia oxide was reduced at increasing ...
