Nan-fiber scaffolds are suitable tools for tissue engineering. Electro spinning materials together with cells presents not adequate to obtain a high cellular zing tissue constructs as the shear force, tensile force, and other physical effects excited in the electro spinning process, which are harmful to cellular differentiation, development and function. However, this limitation has been overco...

introduction: as the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. for this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. methods: in this study, polyhydroxybutyrate (phb) is selected as the scaff...

silver sulfadiazine is used to prevent and treat infections of second- and third-degree burns. it kills a wide variety of bacteria. in this study silver sulfadiazine was used in gelatin based electro-spun nano-fibers with various drug to polymer ratios (0, 5, 10, 15 and 20 %). sem, edx and ftir analysis showed that the continuous, bead-free, fine fibers containing silver sulfadiazine as an anti...

Anisotropic alignment of collagen fibres in musculoskeletal tissues is responsible for the resistance to mechanical loading, whilst in cornea is responsible for transparency. Herein, we evaluated the response of tenocytes, osteoblasts and corneal fibroblasts to the topographies created through electro-spinning and solvent casting. We also evaluated the influence of topography on mechanical prop...

We extend and generalise the string corrections to EM memory Type I superstring including spin effects. Very much as in simpler bosonic context, relevant are non-perturbative $\alpha'$, slowly decaying (as $1/R$) at large distances modulated retarded time $u=t-R$. For $N$ states first Regge trajectory they entail a sequence of derivatives wrt $u$ on `parent' $N=0$ amplitude. also briefly discus...

Zinc oxide nanofibers were prepared using the polymer Zinc acetate solution, by a modest programmable microcontroller aided electro spinning technique. The prepared and calcinated nanofibers were characterized using standard analytical methods. The hexagonal wurtzite structure for calcinated nanofibers of diameters ranging between 10-13 nm were inferred from structural analysis. The Field Emiss...

Nanofiber-based products are widely used in the fields of public health, air/water filtration, energy storage, etc. The demand for nonwoven is rapidly increasing especially after COVID-19 pandemic. Electrospinning most popular technology to produce nanofiber-based from various kinds materials bench and commercial scales. While centrifugal spinning electro-centrifugal considered be other two wel...
