고집적회로에서 A1 금속공정의 diffusion barrier로 널리 사용되는 titanium nitride의 성질을 조사하였다. 실제 회로 구조의 열적 안정성을 관찰하기 위하여 준비된 TiN/Ti다층 barrier를 $600^{circ}C$까지 열처리하여 x-ray photoelectron spectroscopy (XPS), cross-sectional transmission electron microscopy(XTEM) 등으로 분석하였다. 열처리 온도가 증가됨에 따라 oxygen은 TiN 층의 표면과 pure-Ti 층에 pile up 된다. TiN 층의 표면에서는 $600^{circ}C$열처리시 TiN이 분해되어 완전히 $TiO_2$가 형성되며, TiN 층 내에서는... -

본 실험에서는 반응성 스퍼터링법으로 $N_2$/Ar 유속비를 달리하여 약 200 과 650 두께의 비정질 Ti-Si-N막을 증착한 후 Cu (750 )와 Si사이의 barrier 특성을 면저항측정, XRD, SEM, RBS 그리고 Ti-Si-N막에서 질소 함량의 영향에 초점을 둔 ABS depth profiling 등의 분석방법을 통해 조사되었다. 질소 함량이 증가함에 따라 처음에는 불량 온도가 46%까지 증가하다가 그 이상에서는 감소하는 경향을 보였다. 650 의 Ti-Si-N barrier막을 80$0^{circ}C$에서 열처리 후에는 Cu$_3$Si 피크만 관찰될 뿐 Cu피크는 거의 완전히... -

Ti과 Si의 비가 서로 다른 종류의 타 을 $Ar/N_2$의 혼합기체를 사용하여 rf magnetron sputtering방법으로 증착된 Ti-Si-N박막의 증착특성에 대해 연구하였다. Ti-Si-N박막의 조성과 증착률은 각 타 Ti/Si의 비율과 증착시의 질소기체의 유량에 따라 크게 변하였다. 이것은 Ti과 Si의 nitriding 정도의 차이로 인한 서로 다른 sputter yield에 의한 것으로 나타났다. Si이 비교적 적게 포함된 Ti-Si-N박막은 증착시부터 박막내 TiN의 결정화가 일어났으며, 낮은 비저항을 나타내었다. N의 함량의 증가는 박막의 밀도와 압축응력을... -

Recently, Cynanchi wilfordii Radix has gained wide use in Asian countries as a functional food effective for relieving fatigue, osteoporosis, and constipation, particularly in menopausal disorders. However, its anti-inflammatory and anti-microbial activities have not been explored in detail to date. The anti-inflammatory, antioxidant, and anti-bacterial properties of the Cynanchi wilfordii Radix extracts obtained with water, methanol, ethanol, and acetone were compared. All 4 polyphenol-... -

Retinyl palmitate (RP)-loaded pectinate micro- and nano-particles (PMP and PNP) were designed for stabilization of RP that is widely used as an anti-wrinkle agent in anti-aging cosmeceuticals. PMP/PNP were prepared with an ionotropic gelation method, and anti-oxidative activity of the particles was measured with a DPPH assay. The stability of RP in the particles along with pectin gel and ethanolic solution was then evaluated. In vitro release and skin permeation studies were performed using... -

The objective of the present study was to establish the method of measurement of hydrogen peroxide and to estimate the anti-oxidative effect of genistein in the skin. UVB induced skin oxidation and anti-oxidative effect of genistein formulations were evaluated by determining levels of hydrogen peroxide. The mechanism involved in the determination of hydrogen peroxide is based on a color reaction between ferric ion (Fe3＋) and xylenol orange, often called FOX assay and subsequent monitoring of... -

The underlying mechanism commonly applicable for both the positive and negative force-frequency relationships (FFR) was pursued in left atria (LA) of rat and rabbit. The species differences in the roles of Na/Ca2 exchanger and sarcoplasmic reticulum (SR), which are major intracellular Ca2 regulatory mechanisms in the heart, were examined in the amplitude accommodation to the frequency that changed from 3 Hz to the variable test frequencies for 5 minutes in the electrically... -

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... -

Shepherd’s purse, Capsella bursa-pastoris (L.) Medik., has been considered a health food for centuries in Asia and is known to contain the isothiocyanate compound sulforaphane. In this study, we evaluated the anti-inflammatory and antibacterial properties of a sulforaphane-containing solution (SCS) isolated from shepherd’s purse. SCS had significant anti-inflammatory activity indicated by the decreased levels of nitric oxide (NO), cytokines (interleukin 1β [IL-1β], IL-6, and IL-10), and... -

The fruit of the black raspberry (Rubus coreanus Miquel) has been employed in traditional medicine, and recent studies have demonstrated its measureable biological activities. However, the root of the black raspberry has not been studied. Therefore, in this study, we evaluated the anti-inflammatory and antibacterial properties of the root and unripe fruit polyphenols of the black raspberry. Both polyphenols proved to have anti-inflammatory activity as evidenced by the decreased nitric oxide... -

This study was performed to test whether endomorphin-1 has analgesic effect, when locally administrated into inflamed peripheral tissue. Carrageenan suspension (0.5%) was injected intraplantarly into the right paw of Sprague-Dawley male rats, and the rats were subjected to a series of mechanical stimuli with von Frei filaments before and after the injection. Carrageenan-injected rats showed typical inflammatory hyperalgesic signs and decrease of withdrawal threshold, peaked at 3 to 6 hours after...
