Corrosion Science. 9 February 2020, 108528

Abstract:
We have modified Ti6Al4V at the micro and nanoscale by using ion beam irradiation with 5 MeV Si+ ions through 1D micromasks. The passivation layer on irradiated areas inhibits hydrofluoric acid induced etching, leading to pitting contrasts…

Scientific Reports. 2019

Abstract:
Platelets of strontium hexaferrite (SrFe12O19, SFO), up to several micrometers in width, and tens of nanometers thick have been synthesized by a hydrothermal method. They have been studied by a combination of structural and magnetic techniques, with emphasis on Mössbauer spectroscopy…
