A radiograph positioning device was developed to fit with commercially available film holders and implant systems. The device is indexed to the dental implant body and the adjacent dentition by using an implant placement driver and polyvinyl siloxane occlusal registration material. By fitting the device to a conventional film holder, accurate orthogonal radiographs can monitor changes in bone a...

Metal nanomaterials have promising applications in ultrafast photonics due to their broadband operation, large third-order nonlinear susceptibility, and recovery time. We realized a Q-switched pulsed erbium-doped fiber laser based on silver nanoplate polyvinyl alcohol film as saturable absorber. This film, with modulation depth of 15.7%, was integrated into by means sandwich structure. obtained...

Silk sericin has great potential as a biomaterial for biomedical applications due to its good hydrophilicity, reactivity, and biodegradability. To develop multifunctional sericin materials for potential antibacterial application, a one-step synthesis method for preparing silver nanoparticles (AgNPs) modified on polydopamine-coated sericin/polyvinyl alcohol (PVA) composite films was developed. P...

Tungsten trioxide (WO3) is used to prepare the important electrochromic layer of device as a wide bandgap semiconductor material. In this study, WO3 film was successfully prepared by screen printing. To modify thixotropy and wettability ink, polyvinyl alcohol (PVA) 2-perfluoroalkyl ethanol (FSO) were added in ammonium meta-tungstate (AMT) solution. We found that PVA additive could improve dynam...
