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 ...

3D printer for the in-situ building of habitable modules with a raw mixture of binders and the soil of Mars

A student of the University of Aveiro did the “spin-in” of an invention that started to be developed with the collaboration of teachers and investigators of several departments. The invention, that’s been arising interest in the business sector, locally and nationally, aims at the production of habitable modules using the soil in inhospitable locations, and it was specifically thought for Mars ...
