In our previous work, biomimetic calcium phosphate-coated poly(caprolactone) nanofibre meshes (BCP-NMs) were demonstrated to be more effective for supporting cell attachment and proliferation under static conditions, when compared with poly(caprolactone) nanofibre meshes (PCL-NMs). In many applications, in vitro cultivation of constructs using bioreactors that support efficient nutrition of cel...
A core/sheath structured mesoporous silica nanofibre was prepared by coaxial electrospinning combined with the solvent evaporation induced surfactant assembly process. The characterization has given convincing evidence for the continuous highly ordered mesoporous structures, and its catalyst application was tested.
Carbon nanofibre (CNF)/Al2O3 composites with concentrations between 1 and 9 vol.% of CNF were prepared by the traditional ceramic 1 *Corresponding author. Tel/Fax: +34 985733644. E-mail address: [email protected] (J.L. Menendez)
The biocompatibility and osteogenic potential of four fibrous scaffolds prepared by electrospinning of poly(ε-caprolactone) (PCL) was studied with MG-63 osteoblast cells. Two different kinds of scaffolds were obtained by adjustment of spinning conditions, which were characterized as nano- or microfibrous. In addition of one nanofibrous, scaffold was made more hydrophilic by blending PCL with Pl...
The peridynamic method is used here to analyse the effect of van der Waals forces on the mechanical behaviour and strength and toughness properties of three-dimensional nanofibre networks under imposed stretch deformation. The peridynamic formulation allows for a natural inclusion of long-range forces (such as van der Waals forces) by considering all interactions as ‘long-range’. We use van der...
Antioxidant polysulfide nanoparticles can be electrospun within nanofibre scaffold patches to provide anti-inflammatory action.
We propose several schemes to realize a tractor beam effect for ultracold atoms in the vicinity of a few-mode nanowaveguide. Atoms trapped near the waveguide are transported in a direction opposite to the guided mode propagation direction. We analyse three specific examples for ultracold (23)Na atoms trapped near a specific nanowaveguide (i.e. an optical nanofibre): (i) a conveyor belt-type tra...
the study reports some preliminary investigations on the template free synthesis of a scantly investigated polyaniline (pani) derivative-phenylenediamine (pda) by template free method in the presence of oxalic acid (oa) (dopant), using ammonium persulfate as oxidant. polymerization of phenylenediamine (pda) was confirmed by the ft-ir as well as uv–visible studies. the morphology of phenylenedia...
Previous studies have shown that substrate surface chemistry and topography exhibit significant impact on haematopoietic progenitor cell adhesion, proliferation and differentiation. In the present study, the effect of surface amine density and structure of grafted polymer chains on the adhesion and expansion of haematopoietic progenitor cells was investigated. Cryopreserved human umbilical cord...
The aim of this study was to produce a 3D mesh of defect free electrospun cellulose acetate nanofibres and to use this to produce a prototype composite resin containing nanofibre fillers. This might find use as an aesthetic orthodontic bracket material or composite veneer for restorative dentistry. In this laboratory based study cellulose acetate was dissolved in an acetone and dimethylacetamid...
