Published in 2022 at "Journal of periodontology"

DOI: 10.1002/jper.22-0243

Abstract: BACKGROUND Lasers represent a promising method for implant decontamination, but evidence on implant surface changes and subsequent biofilm formation is limited. This study aimed to assess the effect of Er:YAG laser treatment on zirconia and… read more here.

Published in 2024 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-025-05295-5

Abstract: In this paper we derive formulae for the semiclassical tunneling in the presence of a constant magnetic field in 2 dimensions. The ‘wells’ in the problem are identical discs with Neumann boundary conditions, so we… read more here.

Published in 2018 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-018-3468-x

Abstract: A key issue in the evolution of protostellar discs is the analysis of the mechanisms by which the disc is eventually dispersed and the time-scales involved in this process. The photoevaporation is very likely an… read more here.

Published in 2017 at "Journal of Cultural Heritage"

DOI: 10.1016/j.culher.2017.08.004

Abstract: Abstract The past two decades have witnessed an exponential growth in the use of digital supports for data archiving. However, the expected lifetime of these supports is inadequate with respect to the actual needs of… read more here.

Published in 2017 at "Journal of Drug Delivery Science and Technology"

DOI: 10.1016/j.jddst.2017.05.010

Abstract: Abstract The purpose of study was to investigate the dissolution rate enhancement obtained when sodium dodecyl sulfate (SDS) is co-compressed with griseofulvin into discs using a UV imaging-based flow-through dissolution testing setup. Griseofulvin dissolution rates… read more here.

Published in 2021 at "Mechanics Research Communications"

DOI: 10.1016/j.mechrescom.2020.103644

Abstract: Abstract Minimal models involving rigid discs have been studied due to brake squeal and clutch squeal/eek. In this work, a rotating contact element with viscous damping characteristic is developed. It induces additional circulatory effects to… read more here.

Published in 2019 at "Theoretical and Applied Mechanics Letters"

DOI: 10.1016/j.taml.2019.05.005

Abstract: Abstract Rotating discs are the vital part of many types of machineries. Usually there is a tendency to make use of them in higher rotational speeds, but ahead of their complete break down the incidence… read more here.

Published in 2025 at "Publications of the Astronomical Society of Australia"

DOI: 10.1017/pasa.2025.10125

Abstract: Abstract Post-asymptotic giant branch (post-AGB) binary stars are evolved systems that host circumbinary discs formed through mass loss during late stage binary interactions. Their structural, morphological, kinematic, and chemical similarities to planet-forming discs suggest that… read more here.

Published in 2019 at "Molecular pharmaceutics"

DOI: 10.1021/acs.molpharmaceut.8b00836

Abstract: Nanogels are attractive biocompatible materials that enable local delivery of multiple drugs. In this study, we demonstrated that 3D printing technology could be used to precisely construct nanogel discs carrying paclitaxel and rapamycin. 3D-printed nanogel… read more here.
