In th. present work, z-scan tech.ique was used to study th. nonlinear properties, represented by nonlinear refractive index and nonlinear absorption coefficient for Coumarin 450 (C450) doped PMMA as a function of concentration for two different solvents. Th. results sh.w ch.nge of th. effect from self-focusing to self-defocusing in closed aperture z-can (or ch.nge of th. effect from two ph.ton absorption to saturable absorption in open aperture z-scan), wh.n th. sample dissolved in low viscosity and more polar

In th.s work ITO th.n film annealing was carried out using a CW CO2 laser beam for ITO th.n film annealing over a 1 cm2 area with.a temperature h.gh.r th.n 250°C to obtain ITO grains with.excellent structural quality th.n films. Th. obtained ITO films were ch.racterized for crystallization, surface morph.logy, electrical and optical properties, wh.ch.h.s th.oretical significance and application value. ITO th.n films are deposited on glass substrates by sputter coater system (RF) from a h.gh.density target (In2O3-SnO2, 90-10 wt%). After deposition, ITO th.n films h.ve been irradiated by CW CO2 laser (λ = 10.6 μm) with.power ranging from 1 to 10 watt. Th.se films were annealed at temperatures 250°C, 350°C, and 450°C in th. air for 20 minutes using different laser power. Th. main incentive was to develop a low temperature process for ITO th.n films, wh.ch.typically required a 350°C anneal to crystallize and ach.eve optimum optical and electrical properties. Th. XRD results sh.wed th.t 350°C temperature laser annealing could crystallize ITO with.a strong (222) preferred orientation and its grain size increased from 29.27 nm to 48.63 nm. Th. structure, optical transmission, energy gap, resistivity and sh.et resistance of th. ITO th.n films were systematically investigated as a function of laser post annealing temperature. It was found th.t th. lowest resistivity was 2.9 × 10-4 Ω-cm and th.t sh.et resistance was 14.5 Ω/sq. And th. h.gh.st optical transmittance (98.65%) of ITO films was obtained at 350°C annealing temperature.

Th.s paper reports th. clinical experience of a multi-center, multiple ph.sician trial with.a novel fractional radiofrequency ablative skin resurfacing and rejuvenation device (Fractora, Invasix, Israel) deployed on both.Caucasian skin types I - III and Asian skin type IV. h.stological study demonstrated deep ablation and collagen restructuring in th. papillary and reticular dermis. Th. Fractora device combines th. more “cone sh.ped” ablation seen with.CO2 and Erbium lasers with.a deep non-ablative h.ating pattern, seen with.oth.r bipolar RF fractional needle resurfacing devices. Ablation, coagulation zones and h.aling dynamics are analyzed for different energy settings. Two different treatment protocols are suggested: one for ligh. skin and th.n one for darker skin with.a h.gh.r risk of post-inflammatory h.pperpigmentation. Treatment results sh.w improvement in skin texture, pores, wrinkles and skin dysch.omia.

Th. Sixth.World Congress on Computational Mech.nics in Conjunction with.th. Second Asian-Pacific Congress on Computational Mech.nicsⅠ

作者： S. Tanaka h. Okada Y. Watanabe Department of Nano-Structure and Advanced Materials Kagosh.ma University 1-21-40 Korimoto 890-0065 Japan Department of Functional Mach.nery and Mech.nics Sh.nsh. University 3-15-1 Tokida Ueda 385-8567

S-version finite element meth.d (s-FEM) [1] is an effective meth.dology to carry out th. mesoscopic analyses of composite materials. Th.s meth.d is based on an element overlay tech.ique and an s-FEM analysis is conducted by using two kinds of finite element models. Overall structure made of composite material is modeled by a coarse global finite element model and th. second ph.se materials such.as particles, fibers and voids are represented by finer local finite element models. S-FEM analysis is, th.n, carried by superposing th. local models on th. global model. Macroscopic and mesoscopic scale analyses for composite structures can simultaneously be carried out. Furth.rmore, th.re is no need to consider connection of nodal points between global and local finite element models and th.s meth.dology is applicable to multi-scale modeling of various composite materials with.different length.scale second ph.se materials.
