  • Modification of titanium surface via Ag-, Sr- and Si-containing micro-arc calcium phosphate coating. [Journal Article]
    Bioact Mater 2019; 4:224-235Sedelnikova MB, Komarova EG, … Sheikin VV
  • The current research is devoted to the study of the modification of the titanium implants by the micro-arc oxidation with bioactive calcium phosphate coatings containing Ag or Sr and Si elements. The coatings' microstructure, phase composition, morphology, physicochemical and biological properties were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-…
  • A biophysical model for curvature-guided cell migration. [Journal Article]
    Biophys J 2019Vassaux M, Pieuchot L, … Milan JL
  • The latest experiments have shown that adherent cells can migrate according to cell-scale curvature variations via a process called curvotaxis. Despite identification of key cellular factors, a clear understanding of the mechanism is lacking. We employ a mechanical model featuring a detailed description of the cytoskeleton filament networks, the viscous cytosol, the cell adhesion dynamics, and th…
  • Emerging switchable ultraviolet photoluminescence in dehydrated Zn/Al layered double hydroxide nanoplatelets. [Journal Article]
    Sci Rep 2019; 9(1):11498Prestopino G, Arrabito G, … Medaglia PG
  • Layered double hydroxides show intriguing physical and chemical properties arising by their intrinsic self-assembled stacking of molecular-thick 2D nanosheets, enhanced active surface area, hosting of guest species by intercalation and anion exchanging capabilities. Here, we report on the unprecedented emerging intense ultraviolet photoluminescence in Zn/Al layered double hydroxide high-aspect-ra…
  • Composition-Nanostructure Steered Performance Predictions in Steel Wires. [Journal Article]
    Nanomaterials (Basel) 2019; 9(8)Tian KV, Passaretti F, … Cozza P
  • Neutron scattering in combination with scanning electron and atomic force microscopy were employed to quantitatively resolve elemental composition, nano- through meso- to metallurgical structures and surface characteristics of two commercial stainless steel orthodontic archwires-G&H and Azdent. The obtained bulk composition confirmed that both samples are made of metastable austenitic stainless s…
