ObjectiveThe primary aim of this study was to explore the relationship between biophysical structure and function modern suture materials. Particularly suture's ability withstand stressors surgery how material properties affect knot stability. The secondary investigate effect that different knots have on itself. This builds previous research assessing characteristics but in Ultra High Molecular...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Aim: The regeneration of small periodontal defects has been considered an important divide and challenging issue for dental practitioners. aim this preliminary in vitro study was to analyze the effects polycaprolactone (PCL) nanofibers enriched with hyaluronic acid vitamin E vs. nude on gingival fibroblasts activity, innovative graft soft tissue purposes. Methods: Nanofibers were produced PCL (...
Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...
Abstract Solid biopolymer blend systems consisting of chitosan (CH) and methylcellulose (MC) have been prepared in various compositions through the solution casting method are characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA). The XRD data revealed that composed 30 wt.% MC is found ...
Polystyrene (PS) is one form of the plastic that most widely utilized for household application. However, plastics made from PS can pollute environment. Hence, it necessary to modify by mixing with a biodegradable polymer like poly (ɛ-caprolactone) (PCL). The focus this research was determine mechanical and thermal properties PS/PCL polyblends. In research, polyblend are prepared PCL acquired u...
