Optical pressure sensor based on zirconia nanostructures

A group of researchers from a Portuguese university has developed the concept of a gas pressure gauge based on the control of the luminescence from zirconia nanostructures. The invention aims to measure the gas pressure based on the nanoparticles emission that is different depending on the amount of gas molecules surrounding the nanoparticles. Comparing with existing solutions, the advantage of this process, which operate in a pressure range of interest for various market sectors (ex ...

Low Cost Minimum Quantity of Lubricant System

A group of researchers from a Portuguese university has developed a system of "Minimal Quantity of Lubricants" fully functional and automated. The term MQL, "Minimal Quantity of Lubricant", refers to the use of a low lubricant flow (10 to 100 mL / hr) through a high pressure fluid (compressed air). This system is an alternative to most lubrication systems used in machining operations, with both economically and ecological level advantages, contributing to sustainable manufacturing ...
