Our candidacy to the ESA’s Facility Definition Team on Materials Science

~ Matheus A. Tunes ~ Leave a comment

We have submitted our candidacy to the European Space Agency to integrate the Facility Definition Team (FDT) of Materials Science. We aim at bringing to ESA our expertise in investigating metallurgy for space applications. Our focus is to design new lightweight metallic materials that are capable to resist the harsh environmental conditions often found in … Continue reading Our candidacy to the ESA’s Facility Definition Team on Materials Science

Introducing the Zigzag IntermetAllic (ZIA) phases: A new class of nanostructured materials

~ Matheus A. Tunes ~ Leave a comment

With a warm heart, I would like to share with the materials science community our newest preprint on introduction of the "ZIA phases". The ZIA phases further elaborate upon the notion of nanolaminated crystalline solids, extending it significantly beyond the MAX phases lineage of initial transition metal carbides/nitrides. This expansion is highly likely to widen … Continue reading Introducing the Zigzag IntermetAllic (ZIA) phases: A new class of nanostructured materials

A New Era Beckons: The Epoch of Nanometallurgy

~ Matheus A. Tunes ~ Leave a comment

Casting metallic alloys is a primary human activity since the ancient times. Now, by using advanced methods of electron microscopy coupled with the advent of micro-electromechanical devices (MEMS), Diego Coradini and Professor Stefan Pogatscher led a scientific team to a study that demonstrates the feasibility to cast metallic alloys at the nanoscale. Coradini et al. … Continue reading A New Era Beckons: The Epoch of Nanometallurgy

Maximizing corrosion resistance of aerospace aluminium with self-healing coatings

~ Matheus A. Tunes ~ Leave a comment

The use of sol-gel coatings to increase the corrosion resistance of commercial aerospace aluminium alloys is the topic of our most-recent paper at Corrosion Science. In combination with anodization treatment and the use of Ce nanoparticles to fill-in the pores of the anodic layer, we have observed that a post-treatment with sol-gel coatings further increases … Continue reading Maximizing corrosion resistance of aerospace aluminium with self-healing coatings

An entire life dedicated to nuclear radiation physics and mentorship

~ Matheus A. Tunes ~ Leave a comment

Professor Kenya Moore de Almeida Dias da Cunha was a Brazilian nuclear physicist who dedicated her entire life to the study of actinide materials and in the academic education and scientific initiation of the next generation of research scientists. She was a lovely and passionate experimental scientist -- to the best definition of the term … Continue reading An entire life dedicated to nuclear radiation physics and mentorship

The influence of He bubble in strengthening of Copper

~ Matheus A. Tunes ~ 1 Comment

It is good to see that scientists are working hard to better evaluate the effect of He bubbles in metals and alloys! Sharing a very interesting new article showing unequivocally the influence of He bubbles in the strengthening behavior of Copper! By using shock loading, Lear et al. discovered that He bubbles totally collapse, leaving … Continue reading The influence of He bubble in strengthening of Copper

New H-based materials for use in micro-nuclear-reactors

~ Matheus A. Tunes ~ Leave a comment

We just got a preprint available in arXiv.org for the general audience: "Fabrication of bulk delta-phase Zirconium Hydride from Zircaloy-4 for use as moderators in microreactors" (arXiv:2305.02249v1) In this manuscript, we performed a complete electron-microscopy characterization of the delta-phase Zirconium Hydride (delta-ZrH) currently under manufacturing, research and development to be used as moderator materials in … Continue reading New H-based materials for use in micro-nuclear-reactors
