    2019-12-1 · Three-dimensional graphene foams derived from various templates through CVD have demonstrated high surface areas [59,60,152,153]. Those made of Ni foams offer a surface area up to 850 m 2 g −1, which can be modulated by tuning the number of layers deposited with different deposition time and flow rate . However, the intrinsic large pores of ...

  • Accuracy of Three-Dimensional (3D) Printed Dental

    Digital impression devices are used alternatively to conventional impression techniques and materials. The aim of this study was to evaluate the precision of extraoral digitalization of three types of photosensitive resin polymers used for 3D printing with the aid of a digital extraoral optical scanner. The alignment of the scans was performed by a standard best-fit alignment.

  • Electrodeposition of Three-Dimensional Titania

    2019-5-25 · To fabricate a photonic crystal with large and complete photonic bandgap, it often requires backfilling of high index inorganic materials into a 3D polymer template. However, the pore network may become disconnected before the template is completely filled in a conformal coating process, which, therefore, limits the achievable maximum bandgap in the 3D photonic crystals. Here, we demonstrate ...
