Increasing the ejection efficiency and uniformity of nanofibers is the key to applications of electrospinning technology. In this work. a novel electrospinning spinneret with a sheath gas passageway is designed. The frictional resistance that stems from the sheath gas provides additional stretching and restriction forces on the jet. https://www.itsmajorlook.com/great-deal-Chicago-Cubs-Earrings-Round-Design-p21310-limited-grab/
