Published in 2019 at "Applied Surface Science"

DOI: 10.1016/j.apsusc.2018.10.157

Abstract: Abstract Amorphous As2S3 films with surface roughness near 0.5 nm were prepared by thermal evaporation. Raman measurements performed under ultraviolet (UV) laser excitation (325 nm) revealed a series of sharp intense peaks appearing at laser power density… read more here.

Published in 2018 at "Applied Physics Letters"

DOI: 10.1063/1.5030498

Abstract: We have used low energy electron microscopy (LEEM) to study the evolution of the surface structure of BaTiO3(001) during the ferroelectric-paraelectric phase transition (120 °C, P4mm-Pm3m). Transient surface structures appear under heating at temperatures slightly above… read more here.

Published in 2022 at "Eurosurveillance"

DOI: 10.2807/1560-7917.es.2022.27.26.2200477

Abstract: The extent of monkeypox virus environmental contamination of surfaces is unclear. We examined surfaces in rooms occupied by two monkeypox patients on their fourth hospitalisation day. Contamination with up to 105 viral copies/cm2 on inanimate surfaces was… read more here.
