Ultra-small cobalt particles embedded in titania by ion beam synthesis: Additional datasets including electron microscopy, neutron reflectometry, modelling outputs and particle size analysis

Abstract

This Data-in-brief article includes datasets of electron microscopy, polarised neutron reflectometry and magnetometry for ultra-small cobalt particles formed in titania thin films via ion beam synthesis. Raw data for polarised neutron reflectometry, magnetometry and the particle size distribution are included and made available on a public repository. Additional elemental maps from scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) are also presented. Data were obtained using the following types of equipment: the NREX and PLATYPUS polarised neutron reflectometers; a Quantum Design Physical Property Measurement System (14 T); a JEOL JSM-6490LV SEM, and a JEOL ARM-200F scanning transmission electron microscope (STEM). The data is provided as supporting evidence for the article in Applied Surface Science (A. Bake et al. , Appl. Surf. Sci., vol. 570, p. 151068, 2021, DOI 10.1016/j.apsusc.2021.151068 ), where a full discussion is given. The additional supplementary reflectometry and modelling datasets are intended to assist future scientific software development of advanced fitting algorithms for magnetization gradients in thin films.

Effects of electrospun membrane surface morphology on cellular behaviours and osteogenesis of bone marrow mesenchymal stem cells

“…In this study, the four morphologies had no significant effect on the adhesion of BMSCs, probably because of the insufficient significant differences in the roughness and lateral spacing between fibres, and cell migration was guided by material morphology, Yi et al [38] found that huvECs migrated more favourably along parallel aligned fibres than in the vertical direction. In contrast, Qu et al [39] investigated the effect of silk fibroin fibres with different arrangements on the migration of MSCs compared with random fibres of the same diameter. MSCs exhibited higher migration efficiency on the aligned fibres.…”
