Surface-enhanced Raman scattering (SERS) of thiosalicylic acid (TSA) with sulfydryl group was investigated on the surface of electrochemically roughed silver electrode. The result shows that SERS enhancement effect was relative to the concentration and pH, and 1 x 10(-3) mol x L(-1) and pH 4 were the optimal condition…
This report details the progress made in measuring the temperature dependence of the electronic and optoelectronic of devices made with individual carbon nanotubes.
Bi2O3-containing glass-ceramic sealants for sodium sulfur battery are developed by doping the nucleating agent TiO2. The crystallization behavior of the glasses with the dopants is studied. The addition of nucleating agent TiO2 induces the precipitation of Bi2Ti2O7 crystal. The thermal expansion match between the Bi2O…
Oak Ridge National Laboratory (ORNL), in Partnership with Avure Technologies Inc. and Carpenter Technology Corporation, explored methods to improve durability of steels considered essential to bearings in wind turbine applications by using hot isostatic pressing of steel alloy powders as a manufacturing method. The ob…
The accident at the Fukushima Daiichi nuclear power station in Japan is one of the most serious in commercial nuclear power plant operating history. Much will be learned that may be applicable to the U.S. reactor fleet, nuclear fuel cycle facilities, and supporting systems, and the international reactor fleet. For exa…
콜라겐 함유량이 높은 한식메뉴에 대한 미생물학적 위해 평가를 위해 S. aureus와 Salmonella를 삼계탕, 어글탕, 오돌뼈 볶음, 전약, 족발에 접종하여 다양한 저장온도에서 세균수를 관찰하였다. $4^{\circ}C$ 의 저장온도에서는 5가지 콜라겐 함유식품에서 세균의 성장이 관찰되지 않았고, $10^{\circ}C$ 의 경우 삼계탕과 족발이 다른 식품에 비해 세균이 생장하는 패턴을 나타냈다. 저장온도 $20^{\circ}C$ 에서는 전약을 제외한 나머지 식품에서 세균이 생장하였고, $30^{\circ}C$ 에서도 전약만 세균수가 감소하는 것으로 관찰되었다…

EPDM 고무는 여러 가지 용도에 많이 사용되고 있는 소재이다. 화력발전소의 소각로에서 부산물로 발생하는 버텀애쉬(bottom ash)는 플라이애쉬(fly ash)와는 달리 재활용이 거의 되지 않고 있는데, 본 연구에서는 버텀애쉬 및 탈크를 포함하는 EPDM 복합소재를 roll-mill을 이용하여 제조한 후, 기계적, 열적, 전기적 및 경화 특성 등을 분석하였다. 또한 주사전자현미경(scanning electron microscopy, SEM)을 이용하여 복합재료의 모폴로지를 관찰하였다. 일부의 버텀애쉬는 계면활성제를 이용하여 개질한 후 EPDM 복합재료를 제조하여…

DEASPI], the sensitization of lanthanide luminescence is via functional cation The photophysical sensitization process of Eu(tta)4 . DEASPI involves an energy transfer from charge transfer excited state of hemicyanine (aminostyrylpyridinium) cation,…
자기치유형 아스팔트를 구현하기 위하여 치유제로 디메틸페놀을 사용하여 내부층을 이루고 바깥층이 멜라민 수지로 이루어진 마이크로켑슐을 제조하였다. 마이크로캡슐이 내재된 아스팔트는 일반 아스팔트에 비해 높은 기계적성질을 나타내었다. 그대로 길어질수록 마이크로캡슐이 함유된 아스팔트는 함유되지 않은 아스팔트보다 더 높은 충격강도를 나타내었으며 15일의 휴식기간에 최초의 물성을 회복하였다. 이는 X-선 사진에서 보듯이, 깨어진 아스팔트경계면에 있던 마이크로캡슐이 아스팔트와 동시에 깨지면서 캡슐 안에 있던 단량체인 디메틸페놀이 흘러나와 외부의 반응촉매 투입 없이 아스팔트 자체의…
غده پروستات موش صحرایی که در تحقیقات علمی، کاربرد زیادی دارد ساختار بافتی آن با دیگر پستانداران دارای اختلافات قابل توجهی است و در این ارتباط تا کنون گزارشات اندکی در دسترس می باشد. بدین منظور پروستات 5 سر موش صحرایی نر بالغ و سالم با میانگین وزنی 20±180 گرم و سن تقریبی 5/3-3 ماه مورد مطالعه قرار گرفت. نمونههایی به ض…
In this work the synthesization process of nanocrstallite Nd:KTP powders by modified Pechini method was studied. The results of XRD studies indicate that KTP nanocrystallites doped by Nd has orthorhombic phase. The structural and lattice modes of the synthesized nanocrystallite products were investigated by using Micr…
OBJECTIVE: To determine the optimal time for MRI scanning of tumors in BALB/c mice using c-erbB2 antisense probe labeled with superparamagnetic iron oxide nanoparticles. METHODS: SK-Br-3 tumor-bearing BALB/c mice (n= 30) were injected with antisense probe (12.0 mg Fe/kg). MRI scanning was performed on 5 mice before th…
摘要： 无机材料电子迁移率高、光谱响应范围与太阳光谱匹配，而有机材料价格低廉、合成方法简单、容易制作在基底上，因此在太阳能电池中具有更广阔的应用前景。 目前，阻碍有机太阳能电池发展的主要原因是材料的载流子迁移率低、器件稳定性差、吸收光谱与太阳光谱不匹配，导致光电转换效率较低。 若能将有机、无机材料二者的优点相结合，将可提高有机太阳能电池的能量转换效率。 目前的研究已经取得了一定进展，无机材料在受体层、阴极缓冲层、阳极缓冲层中的应用均不同程度地提高了有机太阳能电池的能量转换效率。 本文综述了目前该领域的研究现状，并对今后的研究提出了展望。
Series of CaAl hydrotalcite-like compounds were synthesized by co-precipitation, and the oxides were obtained after being calcined at 800 degrees C. XRD, BET, DTG and TPD were taken to characterize the physicochemical properties of samples, and reactions of SO2 over samples were studied. Results show that precursors w…
Reliable instrumentation, information, and control (II&C) systems technologies are essential to ensuring safe and efficient operation of the U.S. light water reactor (LWR) fleet. These technologies affect every aspect of nuclear power plant (NPP) and balance-of-plant operations. In 1997, the National Research Council…
