needleless electrospinning;nanospider;fiber diameter;solution concentration;voltage;
Needleless electrospinning is the process of forming thin material fibers from the open surface of its solution or melt in a strong electrostatic field. Electrospun non-woven materials are used in various applications that require specific fiber diameters and pore size distributions. Fiber diameter ...

Linear viscoelastic range (LVR) of bread dough with various composites was determined with oscillatory amplitude tests, while frequecy test (performed in LVR) enabled determination of viscoelastic behaviour at small deformation. In order to determine flow characteristics of the dough and to evaluate ...

Powder Injection Molding (PIM) is a 4-step manufacturing procedure for making ceramic or metallic components. It enables production of very small and precisely made components and is therefore ideal for gear production. The production process starts with compounding thermoplastic polymer and metalli ...

Novel wood fiber (WF)-polypropylene composites were developed using the extrusion process with a twin-screw extruder. The influence of different mass addition of WF to unrecycled polypropylene (PP) and recycled PP (R-PP) on the chemical, thermal and rheological properties of the processed WF-PP and ...

The surface properties of wood fiber (WF) filled polymer composites depend on the filler loading and are closely related to the distribution and orientation in the polymer matrix. In this study, wood fibers (WF) were incorporated into thermoplastic composites based on non-recycled polypropylene (PP) ...

Neat (NPP) and recycled (RPP) polypropylene matrix materials were used to prepare wood–polymer composites with untreated wood fibers up to 40 wt.%. Long-term creep properties obtained through the time-temperature superposition showed superior creep resistance of composites with NPP matrix. In part, ...
