Incompatibilidades de interfase en la interacción entre las micropartículas biológicas que normalmente circulan en la sangre y la superficie de los implantes de biomateriales están normalmente asociadas con posteriores reacciones de rechazo por parte del sistema inmune. Ello requiere un modelo explicativo de la conduc…
Abstract : Using solely grain-scale physics-based simulation methods, it is too computationally intensive to account for both (I) global initial boundary value problem (IBVP) conditions, and (II) grain-scale material behavior, to understand fundamentally the mechanics of dynamic failure in bound particulate materials.…

South Korea has entered into some Free Trade Agreements (FTAs) that contain special provisions of outward processing provisions. With the aid of the outward processing provisions, the goods manufactured or processed in the Kaesong Industrial Complex (KIC) are classified as originating from South Korea for the purpose…
in-situ 무유화 유화중합 및 후속 CdS 코팅 공정으로 이루어진 방법을 이용하여 CdS로 코팅된 PMMA 나노입자를 제조하고 그 특성을 분석하였다. 합성된 CdS/PMMA 나노입자의 크기는 201.7 nm 였으며, TGA 및 원소 분석 결과 10.37 wt%의 CdS를 함유하고 있었다. PMMA 입자 표면에 코팅된 CdS 나노결정의 크기는 3.55 nm였으며 주로 (111) 결정면으로 성장되었다. UV-vis 분석 결과 blue-shifting 현상이 관찰되었으며, 이는 CdS/PMMA 하이브리드 입자상태에서의 CdS는 벌크 상태의 CdS가 갖는 2.41 eV…
The thermomechanical treatment consisting of either static (SSA) or dynamic strain aging (DSA) followed by cold rolling and annealing was applied to develop a strong texture in Al-stabilized steel. The effectiveness of SSA and DSA treatments in developing a high average plastic strain ratio and a high (222)/(200) inte…
Steels treated through carburizing thermochemical treatment and quenching and tempering thermal treatment are broadly used in components that need to have hardness and superficial mechanical resistance together with good toughness in the core of the component. Additionally, it is possible to produce surface compressiv…

목적: 본 연구의 목적은 새롭게 개발하여 국산화한 안경테용 셀룰로오스 아세테이트(Cellulose Acetate; CA) 소재의 가공품질 및 생산성 향상을 위해 절삭성에 관한 연구를 수행하였다. 방법: 다양한 절삭 및 이송속도의 변화조건 하에서 절삭성이 평가되었다. CA 소재의 절삭실험은 절삭력, 표면조도 및 칩형상 등의 분석이 이루어졌으며, 이를 통해 절삭성을 평가하였다. 결과: 주축회전수 20,000과 30,000 rpm을 제외하고 고속영역에서 절삭력이 낮게 나타났으며, 고속회전 시 표면조도가 저속회전 조건 보다 우수하였다. 절삭력과 표면조도의 상관관계는 고속회…

Until now, using wood in damp external conditions for structural applications has been a real challenge, chiefly because of the risk of fungal attack. The most effective preservatives are by definition toxic and so have environmental issues both in use and disposal. Whilethere are a few species of wood with good natur…
At present, the problem of environment pollution draws people's attention increasingly. The international communities and organizations established relevant laws to restrict the emission and reduce the harm to human being and environment. In this paper, a numerical simulation model for diesel engine was established by…

El poli (3,4-etilendioxitiofeno) (PEDOT) es uno de los polímeros conjugados más estudiados en los últimos años debido a sus interesantes propiedades electro-ópticas. Este polímero manifiesta conductividad, puede ser usado en dispositivos electrocrómicos y es sintetizado a partir del monómero 3,4-etilendioxitiofeno (ED…
Higher compression ratio is required in diesel engine to ignite the fuel that leads to better efficiency. For complete combustion inside the cylinder it is important to ensure the clean air flow with free of debris and as cool as possible. In this manner, modification of intake valve arrangements is taken in to consid…
Dynamic model used for simulation of an industrial side-fired steam reformer comprises coupled PDEs for concentrations of different components and temperature of the gas phase (i.e., outside the catalyst particles), and second order ODEs for concentrations of components in the catalyst phase (i.e., in the pores of the…
