TL;DR: In this article, the chemical state and the electronic structure of ion-bombarded polymers are studied by XPS and REELS techniques, and the rate and the relative yield of the bombardment induced chemical reactions are shown to depend on the primary chemical structure of the bombarding polymers as well as on the total ion deposited energy, fluence and energy deposition mechanism.

TL;DR: It is found that MSC isolated from the femur of adult patients consistently maintain an osteogenic potential, and these cells are a potential source for bone engineering, either by direct autologous reimplantation or by ex vivo expansion and reim implantation combined to a proper scaffold.

TL;DR: It is demonstrated that the presence of Ca(2+) ions inhibits membrane damage occurring immediately after the interaction of freshly dissolved hIAPP with the membrane, but significantly enhances fiber-dependent membrane disruption.

TL;DR: It is suggested that the formation of a substantial amount of hydrogenated amorphous carbon phases is the major factor promoting the cytocompatibility of ion irradiated polymer surfaces.

TL;DR: In this paper, the first direct quantitative determination of the electric-field-assisted alignment of single organic supramolecular fibers self-assembling at a surface was provided, where the fibers were observed preferentially on the top of the negatively charged electrode and tended to align with the local electric field.
