Detecting Li within electron microscopes is a deep challenge…
Low-energy characteristic X-rays (physicists like the term 'soft X-rays' =]...) are problematic to detect and quantify using existing Energy Dispersive X-ray (EDX) spectroscopy techniques. For example, within Mg-Li alloys, proper detection of Li remains a significant challenge. Very interesting work on instrumentation of EDX coupled with scanning electron microscopy (SEM) has now addressed to this … Continue reading Detecting Li within electron microscopes is a deep challenge…
Physicist on holidays part 1: some fun with marbles!
Some interesting home experiments we are doing (Arnaldo Forner, Pamela Forner and myself). We will write a post about the science of impacting marbles very soon. Marbles and its filled air-bubbles, can this material be considered brittle? https://youtu.be/e4XXuoWV_LU Fracture surface: is it a brittle fracture?
When an atom is just a bunch of pixels…
Breathtaking! Aluminium is the devil's metal...
Stability of single-crystal Cu nanowires in low-reactive plasma enviroments
Flagship international science: a collaboration between University of São Paulo, ETH Zürich and Montanuniversität of Leoben, it is my pleasure to share with you our recent findings on the stability of single-crystal Cu nanowires for future applications in nanoelectronics.

Controlling radiation damage in nanomaterials
Nanomaterials are offering unique opportunities for the design of future nuclear materials. In our recent paper at ACS Applied Nano Materials, we demonstrate that AISI-316 steel nanoparticles are capable of self-healing from the deleterious effect of heavy-ion collisions. We also pose a new question to the materials community on the recyclability of potential nuclear nanomaterials. … Continue reading Controlling radiation damage in nanomaterials
Functionally Graded Materials for Fuel Cells Applications
Our paper on the corrosion resistance of constant and functionally graded TiN coatings is now online! In this paper we have discovery an interesting relationship between electron energy loss spectroscopy and corrosion resistance: functionally graded materials can be engineered so that they have a gradient of valence electrons along the coating profile. The less electrons … Continue reading Functionally Graded Materials for Fuel Cells Applications
