With the growing urgency to decarbonize energy systems, proton exchange membrane fuel cells (PEMFCs) have gained prominence as a clean power source. A critical barrier to their widespread adoption, however, lies in the cost and durability of bipolar plates (BPPs), essential components often reliant on expensive noble metals. In a recent study, we explored the … Continue reading Metal-carbon interfaces for future hydrogen-energy systems

Hydrogen embrittlement (HE) remains a critical challenge in materials engineering, particularly for industries reliant on high-performance metals, such as energy and transportation. As hydrogen atoms diffuse into metals, they weaken the material’s structural integrity, leading to reduced load-bearing capacity and increased brittleness. A deeper understanding of hydrogen’s interactions with metal lattice structures, defects, and stress … Continue reading Investigating Hydrogen Embrittlement to Develop Superior Functional Alloys – Prof. Dr. Livia C. Malheiros (UK)
In a recent interview with Estadão, I had the opportunity to discuss the promising role of green hydrogen in advancing sustainable practices within agriculture and industry. We explored the significant challenges associated with large-scale adoption, including the low volumetric energy density of hydrogen, the energy-intensive nature of its production, and the phenomenon of hydrogen embrittlement … Continue reading Exploring the Future of Green Hydrogen and Sustainable Aviation Fuel in Brazil
I am a huge admirer of Dr. Sabine Hossenfelder and her insightful reviews of science and global scientific activities.

This week, we had the pleasure of attending the 24th European Conference on Fracture (ECF) in Zagreb, Croatia. The experience was truly remarkable, with the conference offering a wealth of insights and opportunities to connect with experts in the field. The community of hydrogen embrittlement likes to destroy materials more than any other community in … Continue reading Highlights from the 24th European Conference on Fracture in Zagreb, Croatia
If asked to name a person who changed the course of the 20th century, one think of Lise Meitner. This brilliant and ingenious physicist, often overlooked by many, was the first to recognize the potential of the atom as a source of energy. Meitner's groundbreaking work on nuclear fission, though eclipsed by history (and the … Continue reading Hydrogen Offers a New Perspective for Europe’s Future
