摘要： The present invention relates to a biomimetic matrix for providing structural support and scaffolding that allows for regeneration of dentin, pulp, and periodontal tissues. A method of making the biomimetic matrix provides the ability to select both a size of a pore or tubule formed in the biomimetic matrix and a density of pores or tubules disposed throughout the biomimetic matrix. The present invention discloses an approach of successful tubular dentin regeneration both in vitro and in vivo using the biomimetic matrix.

摘要： Poly-(caffeyl alcohol) (PCFA), also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. PCFA can be used to produce carbon fibers by direct electrospinning, without blending with another polymer to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that obtained from other lignins. The fibers formed from PCFA are smoother, have a narrower diameter distribution, and show very low defects. The PCFA can be obtained by extraction from plant seed coats. Examples of these plants include the vanilla orchid, Vanilla planifolia, and Jatropha curcas. The fibers may be formed through electrospinning, although other methods for forming the fibers, such as extrusion with a carrier polymer, could be used. The fibers may then be carbonized to increase the carbon yield.

摘要： An ultrafine fiber printing system contains a moving deck having a nozzle seat that disposed on the moving deck. A pipe is installed in the nozzle seat and a nozzle is disposed at the bottom end of the pipe. The upper portion and the lower portion of the pipe are combined with a heat dissipating unit and heater respectively. The top end of the pipe is connected to a feed tube having an outer end being connected with a thread squeezer. A printing platform is disposed around the moving deck. The nozzle is connected to a static electricity supply and the fiber carrier is grounded. An electric field is formed between the nozzle and the fiber carrier. The droplets exported from the nozzle are stretched into ultrafine fibers to form a patterned fabric or product.
