Austenitic stainless steel materials are widely used in systems that require high oxidation resistance and corrosion resistance. However, in contact with other surfaces, these materials show a high coefficient of friction ...

Este trabalho apresenta um estudo das propriedades mecânicas e tribológicas de compósitos de alumina reforçados com partículas de nióbio obtidos pela técnica de sinterização por plasma pulsado (Spark Plasma Sintering – ...

The objective of this work was to obtain an EPDM elastomeric formulation for application at high temperatures. The influence of characteristics such as the ethene, propene, and diene content and Mooney viscosity, the use ...

Contamination by bacterial biofilms has a strong negative impact, especially when given on the surface of prostheses, implants, pins and other medical-surgical devices. In this study metal samples of Titanium cp and AISI ...

Diamond-like Carbon films (DLC) films, despite research being developed over four decades, have restricted industrial use and prevent massive application in recent years due to the low adhesion of this material to ferrous ...

Quantum carbon dots (CQDs) are amorphous carbon nanoparticles that have specific functionalities, among them, the fluorescence emission at particular wavelengths and the production of singlet oxygen (1O2). However, due to ...

Copper-beryllium alloys are widely used to manufacture thermoplastics injection molds due to their high thermal conductivity. Even though these alloys admit precipitation hardening at temperatures between 250 and 400 ºC, ...

Upper limb amputations occur frequently throughout the world and are mainly caused by trauma, such as car accidents or accidents involving industrial machinery. The development of prosthetic technologies is a growing need ...

Over 1.5 million ureteral stents are implanted globally each year, yet more than 80% are reported to fail due to complications such as ureterovesical reflux, tissue irritation, and infectious crystalline biofilm formation. ...
