Excellent Method

Melt electrospinning is a novel technology in the field of 1D micro/nanostructure fabrication. Decreasing the diameter and promoting surface morphology of melt fiber are the key for the application of melt electrospinning technology. Heated sheath gas is introduced to build up melt electrospinning direct-write technology, and then orderly micro/nanofibers can be direct-written. The heated sheath gas provided a good way to increase the temperature of melt jet, by which solidification can be slowed. With the help of heated sheath gas, the diameter of melt fiber can be decreased. The affects of process parameters on the diameter of melt electrospinning fiber was investigated, the diameter of melt electrospinning fiber increased with the increasing of temperature of spinneret and feed rate, but decreased with the increasing of voltage and distance between spinneret and collector. Heated sheath gas is an excellent method to promote the application of melt electrospinning.

Consistent Response

A tongue pressure unit for measurement of lingual strength and patterns of tongue pressure is described. It consists of a force displacement transducer, a single channel, direct writing recording system, and a specially designed tongue pressure disk, head stabilizer, and pressure unit holder. Calibration with known weights indicated an essentially linear and consistent response. An evaluation of subject reliability in which 17 young adults were tested on two occasions revealed no significant difference in maximum pressure exerted during the two test trials. Suggestions for clinical and research use of the instrumentation are noted.
