  • This paper presents an advanced engineering technique using finite element analysis to improve structural silicone glazing (SSG) design in high-performance curtain wall systems for building facade. High wind pressures often result in bulky SSG aluminum extrusion profile dimensions. Architectural desire for aesthetically slender curtain wall sight-lines and reduction in aluminum usage led to optimization of structural silicone bite geometry for improved stress distribution through use of finite element analysis of the hyperelastic silicone models. This advanced design technique compared to traditional SSG design highlights differences in stress distribution contours in the silicone sealant. Simplified structural engineering per the traditional SSG design method lacks accurate forecasting of material and stress optimization, as shown in the advanced analysis and design. Full scale physical specimens were tested to verify design capacity in addition to correlate physical test results with the theoretical simulation to provide confidence of the model. This design technique will introduce significant engineering advancement to the curtain wall industry and building facade.

  • 기판/Py/Al2O3/Co(Py=Ni81Fe19) 터널접합의 TMR(Tunneling Magnetoresistance)에 미치는 기판과 부도체층의 효과를 보기위해 산화시간을 변화시키고 기판의 종류를 변화시켜며 전기적 특성을 측정하였다. 시료는 진공중에서 in-situ로 새도우마스크를 교환하며 제작하였다. 산화시간의 증가에 따라 터널접합의 저항은 증가하였으며 측정된 MR 값은 감소하였다. 터널 비저항이 0.17 M$\Omega$($\mu\textrm{m}$)2이하인 경우 MR이 관측되었다. 기판의 종류에 따른 MR 값은 열산화시킨 Si(111), Si(100), Cornng Glass 2948, Corning Glass 7059 순으로 감소하였다. MR 값의 부호와 변화를 불균일 전류의 흐름으로 설명하였다.

  • 본 논문에서는 800nm급 펨토초 레이저와 위상마스크를 이용하여 게르마늄이 첨가된 일반 광섬유(Corning SMF-28)에 FBG 센서를 가공하였다. 제작된 FBG 센서는 누적방사선 100 kGy급 감마선에 조사하여 방사선 영향을 평가하였다. fs-FBG-2 센서는 방사선 조사 중에 불완전한 광특성을 보였지만, fs-FBG-1 센서는 누적선량 100kGy에서 Bragg 파장변화가 10pm 이하로 나타나 뛰어난 내방사선 특성을 보였다.

  • Single crystalline Au nanowires were successfully synthesized in a tube-type furnace. The Au nanowires were grown by vapor phase synthesis technique using solid-liquid-solid (SLS) mechanism on substrates of corning glass and Si wafer. Prior to Au nanowire synthesis, Au thin film served as both catalyst and source for Au nanowire was prepared by sputtering process. Average length of the grown Au nanowires was approximately 1 ${\mu}m$ on both the corning glass and Si wafer substrates, while the diameter and the density of which were dependent on the thickness of the Au thin film. To induce a super-saturated states for the Au particle catalyst and Au molecules during the Au nanowire synthesis, thickness of the Au catalyst thin film was fixed to 10 nm or 20 nm. Additionally, synthesis of the Au nanowires was carried out without introducing carrier gas in the tube furnace, and synthesis temperature was varied to investigate the temperature effect on the resulting Au nanowire characteristics.

  • Sintering and dielectric characteristics of substrates were estimated by mixing rate of alumina and potashborosilicate glass(PBSG) powders. PBSG powders were used 7761(corning code)and alumina powders were used in extra pure rate(99.9%) and had 0.1 ${\mu}$m mean size. After ball milling with organic additives green sheets which were casted by doctor blade machine were sintered at 800$^{\circ}C$ for 1∼3hrs. Microstructure, linear shrinkage and dielectric constant of substrates were surveyed in order to fabricate low-dielectric and low tem-perature sintering substrate.

  • CaTiO₃:Pr phosphor thin films were prepared on Si(100), ZnO/glass, Corning glass and ITO/glass by rf magnetron reactive sputtering. The effects of deposition parameters such as oxygen partial pressure, substrate temperature, and annealing conditions on crystallinity and compositional variation of the films were investigated. PL spectra of CaTiO₃:Pr phosphor thin films exhibited red regime peaking at 613 nm and enhanced PL intensity was observed for the film annealed in vacuum atmosphere as compared to the deposit annealed in N₂ environment.

  • The poly silicon thin films were prepared by solid phase crystallization at 600$^{\circ}C$ of amorphous silicon films deposited on Corning 7059 glass and (100) silicon wafer with thermally grown SiO$_2$substrate by plasma enhanced chemical vapor deposition with varying rf power, deposition temperature, total flow rate. Crystallization time, microstructure, absorption coefficients were investigated by RAMAN, XRD analysis and UV transmittance measurement. Crystallization time of amorphous silicon films was increased with increasing rf power, decreasing deposition temperature and decreasing total flow rate.
