In the present study, the effect of simulated firing cycle on age-hardenability of Au-Cu-Zn alloy containing Cr at intraoral temperature was evaluated by means of hardness test, X-ray diffraction (XRD) study, scanning electron microscopic (SEM) observation, electron probe micro analysis (EPMA) and differential thermal…
We proposed a quick patterning method using a gel-nanoimprint process to fabricate a photonic crystal layer using zinc oxide (ZnO). The X-ray diffraction measurement revealed that the ZnO layer had a wurtzite structure by annealing in air or oxygen ambient. We demonstrated the nanopatterning with a short imprinting ti…
This experimental study is to explore the relationship of the impact crater’s shape and its projectile. In order to get a better estimation of the craters parameters, only the most clearly defined and typical crater patterns are chosen. An experiment was conducted at STRIDE (Science Technology Research Institute for D…
Durante los últimos años, ha adquirido importancia creciente el estudio de la interacción radiación visible-materia (fotónica), en la que la primera queda confinada a volúmenes de dimensiones mucho menores que la longitud de onda de la luz. El conocimiento de los procesos físicos que ocurren en dicha interacción permi…
Στην παρούσα διδακτορική διατριβή έγινε μια προσπάθεια για την ανάδειξη του σημαντικού ρόλου της ανακύκλωσης του γυαλιού και των υαλοποιημένων απορριμμάτων. Κριτήριο για την επιλογή των δομικών υλικών τα οποία θα μπορούσαν να παραχθούν εναλλακτικά από ανακυκλωμένο υαλόθραυσμα και υαλοποιημένα απόβλητα ήταν η ποσότητα…

본 연구는 시멘트 혼화용 폴리머를 스티렌과 부틸 아크릴레이트를 단량체로 이용하여 유화제의 첨가량을 달리하여 합성제조하고 제조된 폴리머를 시멘트 모르타르에 혼입하여 그 특성을 파악함으로써 시멘트 혼화용으로써의 사용가능성을 확인하고자 하는 기초적 실험이다. 유화제 첨가량과 단량체비를 달리하여 스티렌-부틸 아크릴레이트(styrene/butyl acrylate)계 폴리머 시멘트 모르타르의 특성은 물-시멘트 비, 공기량, 강도, 방수성 및 염화물 이온 침투저항성을 측정하여 그 특성을 파악하고자 하였다. 연구 결과 보통 시멘트 모르타르에 비해 유화제의 첨가량이 6%일 때, S…
The influence of lattice strain on the oxygen exchange kinetics and diffusion in oxides was investigated on (100) epitaxial La[subscript 1–x]Sr[subscript x]CoO[subscript 3−δ] (LSC) thin films grown by pulsed laser deposition. Planar tensile and compressively strained LSC films were obtained on single-crystalline SrTiO…
A complex of Cu(II) with 1-(6-HydroxyNaphthalen-2-yl) Butane-1,3-Dione (HNBD) was synthesized and characterized by elemental analysis, IR, UV and DTA-TG-DTG techniques. IR spectra as well as UV-visible absorption measurements indicated that Cu(II) ion was coordinated to the HNBD ligand. The TG-DTA-DTG curves showed th…
