[HTML][HTML] Making sustainable aluminum by recycling scrap: The science of “dirty” alloys
There are several facets of aluminum when it comes to sustainability. While it helps to save
fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts …

Recent search for new superhard materials: Go nano!
S Veprek - Journal of Vacuum Science & Technology A, 2013 - pubs.aip.org
High elastic moduli do not guarantee high hardness because upon finite shear electronic
instabilities often occur that result in transformation to softer phases. Therefore, the author …

Self-formation of compositionally complex surface oxides on high entropy alloys observed by accelerated atom probe tomography: a route to sustainable catalysts
Sustainable catalysts rely on abundant elements which are prone to oxidation. A route to
non-noble electrocatalysts is opened by directing the formation of unavoidable surface …

Limits to the preparation of superhard nanocomposites: Impurities, deposition and annealing temperature
S Veprek, MGJ Veprek-Heijman - Thin Solid Films, 2012 - Elsevier
Impurities, in particularly oxygen, degrade the mechanical properties of superhard nc-TiN/a-
Si3N4 nanocomposites. In the present paper we show that relatively small oxygen impurities …

Negative effect of vacancies on cubic symmetry, hardness and conductivity in hafnium nitride films
Although vacancies exist commonly in nonstoichiometric transition metal nitrides, their roles
on structure and properties are not yet well explored. We show that in rocksalt hafnium …
