Purpose: The SupraFOIL smooth nylon foil implant is a polyamide sheet available in varying thicknesses that has been used in orbital reconstruction following trauma. The authors report their experience with smooth nylon foil implants in the repair of orbital fractures.
Methods: A retrospective chart review of patients having undergone repair of orbital fractures between January 1, 1995 and December 31, 2003 was conducted. The Wilcoxon test was used to compare cases with complications and those with no complications.
Results: Of 282 orbits that underwent fracture repair with alloplastic material, 87 were excluded because non-nylon foil implants were used alone or in combination with nylon foil to repair the orbital fracture. An additional 14 fractures were excluded because of insufficient clinical data or lack of follow-up, for a total of 181 orbits that underwent orbital fracture repair with only nylon foil. A transconjunctival approach was used in 98% cases, and all 181 implants were fixated with at least 1 titanium screw. Average follow-up was 362.8 days. The overall complication rate was 1.7%. One patient had an acute postoperative orbital hemorrhage (0.6% acute complication rate). Two patients had late orbital infections, 683 days and 984 days following repair (1.1% late complication rate).
Conclusions: The authors found the smooth nylon foil implant to be safe and effective in orbital fracture repair. The lower rate of complications the authors observed compared with previously reported series may be related to implant fixation. A titanium screw secured just posterior to the orbital rim may decrease long-term complications by providing more stability than implants left without fixation.

As an emerging high-efficiency energy conversion device, improving the output of triboelectric nanogenerators (TENGs) is still a key method to promote practical application of TENGs. This paper systematically investigated the influence of component composition, thickness, and surface morphology of the metal conducting layer on the performance of triboelectric nanogenerators. It has been established that these three factors have a significant influence on the output performance of TENGs.

Hydrogels are a class of biomaterials that can provide a three-dimensional (3D) environment capable of mimicking the extracellular matrix of native tissues. In this chapter, we present a method to generate electrospun nanofibers for the purpose of reinforcing hydrogels. The addition of electrospun fibers can be used to improve the mechanical properties of hydrogels and broaden their range of applications.

Purpose: Foreign body reaction to non-absorbable alloplastic orbital implants utilized for bony reconstruction are infrequently documented in the literature. We present the workup and surgical management of a giant cystic mass encapsulating a patient's alloplastic orbital implant, which was ultimately deemed to be a result of foreign body reaction.
Observations: A 41-year-old male patient with distant history of a right orbital floor fracture had undergone repair with the placement of a nylon foil implant.

In this work, we report a vertical contact-separation mode triboelectric nanogenerators (TENG) comprising of NiC/PDMS composite and Nylon Nanofibers for self-powering a nichrome wire-based thermal patch for muscular/joint relaxation. An optimised composition of NiC (25 wt%) and PDMS as a tribo-negative material and Nylon Nanofibers synthesised via electrospinning on copper electrode foil as a tribo-positive material were used to fabricate the TENG. The fabricated TENG exhibits outstanding output generating an average open circuit voltage of ∼252 V, an average short circuit current of ∼40.
