The two-dimensional (2D) assembly of the palladium nanoparticles (Pd NPs) was studied in this work. The cubic Pd NPs were successfully synthesized and assembled on mica and silicon wafer in the dip-coating way. The morphology of the Pd NPs and the topography of the Pd NPs assembly on the substrates were characterized…
According to development environment of Diesel vehicle in recent years, emission situation, emission characteristics and treatment technologies of black carbon in diesel vehicle exhaust gas were investigated. Through comparative analysis of existing technologies, strategies and recommendations for resolving black carb…
The thermal oxidation kinetics of natural rubber containing hydrazine dihydrochloride or hydrazine sulfate used as tackifier were studied, and the effective storage time of natural rubber containing tackifier was predicted with a method of heat accelerated storage aging. The results show that the thermal oxidation act…
The present study is pertaining to the influence of biofilm on pitting corrosion of UNS 31603 stainless atel in the sea water medium. These materials are welded and aged at 450℃ for 10000 hours. The corrosion behavior of weld materials are compared with similarly aged base metal (BM). Corrosion studies were conducted…
In this paper, an ultra-thin LC resonator structure operating in X-band is designed which is intended to be used as a shield to reduce the radar cross section of a conducting plate. The proposed structure is simulated using Ansoft HFSS software which shows an absorption peak at 8.125 GHz with reflection coefficient of…
Scaffold plays an important role in tissue engineering. In this study, porous PLGA scaffold was successfully prepared by mixed solvent systems using the thermally induced phase separation method. The PLGA scaffold shows fibrous matrix and interconnective pores, and the scaffold has high porosity and compressive modulu…
The deformation behavior and constitutive equation of Mg-4Al-3Ca-1.5Zn-1Nd-0.2Mn alloy were investigated using hot compression tests at the temperatures range of 200, 250, 300, and 350°C with the constant strain rates of 0.001, 0.01, 0.1 And1 s-1. The influence of strain was also incorporated in the constitutive equat…
Dissolved gas analysis (DGA) is an effective tool for detecting incipient faults in power transformers. The ANSI/IEEE C57.104 standards, the most popular guides for the interpretation of gases generated in oil-immersed transformers, and the IEC-Duval triangle method are integrated to develop the proposed power transfo…

The uniaxial compressive strength and Young’s modulus of intact rocks are the most important analytical parameters for design of rock mass structures. But the preparation of the samples for uniaxial compressive test is a hard and time consuming task. By using ultrasonic test, engineers can predict the analytical param…
This study was performed to develop the source profiles for fine particles (PM 2.5 ) emitted from the meat cooking. The characterization of fine particles emitted from beef cooking showed comparably high level of carbon (75%) which mainly composed of OC (73%) and EC (2.3%). Also the level of K+, Cl-, K, Cl, and Na+ ha…
Photo electrode is an important component for DSSC. DSSCs electrical characteristics and efficiencies fabricated with different TiO2 photo electrodes thickness and modified phoro electrode surface area were studied. 11 ㎛ TiO2 photo electrode shows a 4.956% efficiency. The highest short circuit current density was a 9.…
가동중검사 동안 가압중수로 압력관에서 탐지된 베어링 패드 프레팅 결함, 이물질 프레팅 결함 등 체적결함에 대해서는 CSA N285.8-05 에 따라 탄성 응력집중계수 수식을 이용하여 피로균열 및 수소지연균열이 개시되는 것을 평가하여야 한다. CSA N285.8-05 에는 이물질 프레팅 결함에 대해서는 선형파괴역학 기반한 개략적인 수식만이 제시된다. 본 연구에서는 이러한 이물질 프레팅 결함에 대해 2 차원 유한요소 해석과 일부 수정된 Kinectrics 사의 공학적 절차를 통해 이물질 프레팅 결함의 기하학적 특성이 좀더 상세히 고려된 탄성 응력집중계수 수식을 도출하였…

Emission regulations for diesel engines are becoming increasingly stricter worldwide, which make the modification to the SCR aftertreatment systems for marching various diesel engines of different emission levels become an urgent problem. This work presented a complete urea-SCR modeling approach. An accurate urea-SCR…
This paper presents a study on the adsorption of structurally different C.I. Acid Red 1(AR-1) and C.I. Acid Yellow 4(AY-4) from aqueous solution by a series water-insoluble crosslinked cationic starches with different degrees of substitution (DS) synthesized by a dry process. The adsorption quickly establish equilibri…
According the high energy consumption and pollution in foundry industry, the reason of high energy consumption and the source of the pollution were analyzed. Based on the analysis, for the sustainable development of foundry industry, some effective measures were suggested: defining the responsibility of all referred p…
Various ways to create a master radiator at wavelength 1.315 μm are considered, and its optimum construction layout is chosen, based on obtaining efficient emission of the second Stokes component in a stimulated-Raman-scattering solid-state laser. An analysis is given of active crystals, and two solid-state pairs are…
