In this paper, we give a fundamental convexity preserving for spectral functions. Indeed, we investigate infimal convolution, Moreau envelope and proximal average for convex spectral functions, and show that this properties are inherited from the properties of its corresponding convex function. This results have many applications in Applied Mathematics such as semi-definite programmings and eng...

scaffold design has pivotal role in tissue engineering. in the present study, we modified the surface of electrospun poly(caprolactone) (pcl) nanofibers to improve their compatibility with living medium and to show the potential application of pcl nanofibers as a artificial extracellular matrix using in tissue-engineering. pcl nanofibers were fabricated by electrospinning method. to graft gelat...

objective: the bioscaffold can be used in tissue engineering and regenerative medicine. the scaffolds used in tissue engineering must have high porosity to facilitate accelerated angiogenesis for feeding cells and repelling cell waste outside the scaffold. in this experimental study, we attempted to produce lung three-dimensional scaffold and assay its effect on cell penetration and migration. ...

Tissue engineering is based on three main factors including scaffolds, cells and growth factors. Natural scaffolds derived from decellularized tissues and organs have been successfully used in tissue engineering. Decellularization studies have shown that natural scaffolds which maintaine their main structure and properties could be a suitable tool for studying cellular behaviors and preparation...

Nanotechnology is a favorite research area that revolutionized mechanical and chemical properties of materials. Recently, focusing on concrete as a porous material with micro-scale and nano-scale pores enthusiastic researchers developed their investigations to find out microstructure and mechanical properties of concrete. The aim of this paper is to investigate the effect of nano-silica as an a...
