V, et al. Adhesion, growth, and matrix pro- duction by osteoblasts on collagen substrata. Calcif Tissue Int 1992;51:202-12. 22. Lynch MP, Stein JL, Stein GS, Lian JB. The influence of type I collagen on the development and maintenance of the osteoblast phenotype in primary and passaged rat calvarial osteoblasts: Modification of expression of genes supporting cell growth, adhesion, and ex-... Purpose: The aim of this study was to evaluate the bone inducing effects on the maxillary sinus of rabbits using the first commercial rhBMP-2 in South Korea and to investigate the influence of supplementation with collagen sponges. Materials and Methods: Two circular windows (diameter, about 4 mm) was formed in the nasal bone of rabbit The preparated maxillary sinuses were filled with collagen sponges (Terudermis?) alone in three groups. In the other three groups, the preparated maxillary... -

nano- crystals and on their adhesion. Ba-Abbad et al. [22] reported that temperature had a profound effect on the particle size, shape and catalytic activity of TiO 2 nanoparticles synthesized with the sol-gel method made up of titanium tetra isopropoxide, ethanol and water. Generally, irrespective of the temperature, it was observed that at a longer holding time, specifcally 4 h, all the PAN... This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy... -

5. Because the interfacial adhesion between the CNT and epoxy matrix influences to the phonon conduction, the experimental results showed the composites containing amino-functionalized CNT had lower thermal conductivity than pristine CNT incorporated composites due to reduced interfacial adhesion (Fig. 6).

형성되어 있고，화학적 유지 형태를 보이는 브라켓은 silane layer 로 처리되어 chemical adhesion 을 이루며，복합 형태는 2 가지가 혼합되어 있다. Starfire 미세구조에 대해 Eliades 둥3〉은 무지개 색 으로 코팅되어 물결 형태를 보이며 어떤 점 주위의 줄무늬들은 silane layer 의 다양한 두께를 의미하는 둣하고 투사광선의 다중 굴절에 의해 여러 층으로 나 타난다고 하였다. 화학 결합 형태로서 이용된 silane... 여러 세라믹 브라켁과 접착제에 따른 전단 결합 강도를 비교하기 위하여, 영구 소구치 48개를 대상으로 베이스이 유지 형태가 다른 3종의 세라믹 브라켓을 광중합과 화학 중합을 포함한 3종위 교정용 접착제를 사용하여 접착하고 전단 결합 강도와 파절 양상을 관찰한 결과, 화학 중합형 레진으로 접착한 경우 광중합형으로 접착한 경우보다 결합 강도가 높았으며, 화확적 결합을 하는 Starfire 브라켓이, 기계적 결합을 하는 Transcend나, 복합형 결합인 Fascination보다 전단 결합 강도가 낮았다. Trascend는 주고 법랑질과...
