BACKGROUND To avoid a static double-eyelid fold characterized by nonmobile overdepression of the fold, we propose a new surgical approach of using septoaponeurosis junctional thickening (SAJT) to create a dynamic fold. METHODS Six hundred eighty patients underwent double-eyelid surgery using the SAJT fixation technique. The orbital septum was exposed and(More)
3.5 nm sized Pt nanocatalysts supported on silicon oxide nanowires (SiO(X)NWs) were fabricated by decorating the SiO(X)NWs with Pt nanoparticles using a simple physical deposition system without any surface pretreatment. High curvature of the nanowire surface together with the weak metal-substrate interaction helped to maintain discrete particle morphology(More)
A monolayer of Co-Pt alloy nanoparticles in the nanometer-size regime was fabricated using a nanotemplate approach. 1.7-nm-thick Co46Pt54 film was deposited onto a preexisting array of Ni seed particles embedded in a polyimide film. During subsequent annealing, the deposited Co46Pt54 film coalesced onto the seed particles to produce a monolayer of Co-Pt(More)
Ni nanoparticles embedded in a polyimide (PI) matrix were fabricated by selectively oxidizing a layer of Ni(80)Fe(20) metal film sandwiched between two PI precursor layers. Ni nanoparticles, formed in a monolayer between two PI layers, had an average particle size of approximately 5 nm. X-Ray photoelectron spectroscopy confirmed that Fe in the film was(More)
A mono-layer of nano-sized metal particles was prepared on the surface of a polyimide film by simply depositing a thin film of Ni80Fe20 on top of the polyamic acid that was spin coated onto a Si wafer. During thermal imidization of the polyamic acid film, Fe was selectively etched by reacting with the carbonyl group of the polyamic acid to leave behind(More)
SUMMARY Performing secondary rhinoplasty in patients who underwent primary rhinoplasty using a silicone implant is difficult due to thinning of nasal skin and formation of a capsule. Excess capsule formation can cause capsular contracture, resulting in short nose deformity or implant deviation, migration, or implant demarcation. Revision rhinoplasty using a(More)
