Micromachined superhydrophobic surfaces by Chen Longquan thesis 2009 xvi, 92 p. : ill. ; 30 cm Superhydrophobic surfaces have attracted a lot of attention since the potential applications of self-cleaning effect in self-cleaning textiles, fluid transport in micro/nanofluidics, bio-MEMS and…Read more ›
The production of energy without polluting our atmosphere is one of the key challenges faced by our generation. Fuel cell, is one of the promising technology to produce clean energy to our future, needs clean hydrogen and air as their feed. Finding out optimum condition for the production of hydrogen from various fuel…
돈태반은 미백효과가 있다고 알려져 있으며 화장품의 재료로 사용된다. 또한 가축의 무게를 증가시키고 면역력을 향상시켜 축산농가에서도 가축의 사료로도 사용이 된다. 그러나 이러한 돈태반의 효과가 과학적으로 입증되지는 않았다. 우리는 멜라닌을 분비하는 B16F10에 돈태반을 농도별로 처리한 결과 멜라닌 합성에 관...
With the introduction of new, and highly sophisticated spent fuel dry cask storage and transportation designs involving three-dimensional non-linear dynamic finite element analyses, using codes such as: ANSYS, LS-DYNA, ABAQUS and others, industry as well as the U. S. Nuclear Regulatory Commission (NRC) is faced with u…
The modification of biomedical device surfaces with materials that exhibit antimicrobial properties has been shown to potentially reduce the possibility of infections. An infection arises from the accumulation of bacteria on the surface, forming a layer of biofilm. It is important to prevent the formation of biofilm b…
To improve the friction and wear behavior of carbon fabric reinforced polymer composites (CFRP), nano- SiO2 was deposited on the fabric surface. The friction andwear behavior of the resulting compositeswere investigated on amodel ring-on-block test rig. Experimental results revealed that fiber surface treatment contrib…

Kalvobioreaktori on biologisen jätevedenpudistuksen kehittynyt muoto, jossa lietteen erotus puhdistetusta jätevedestä tapahtuu kalvosuodatuksella tavanomaisen selkeytyksen sijasta. Erilaisten biomassojen prosessointi lisääntyy ja jätevedet näistä toiminnoista ovat usein erittäin väkeviä. Tässä tutkimushankkeessa kalvo…
Fuel cells are energy conversion devices that operate by converting the chemical energy stored inside appropriate fuels into electrical energy. In particular, Solid Oxide Fuel Cells (SOFCs) are a type of fuel cell that has unique characteristics that make them outstanding candidates for use in future power generation…
N3.2-B2-01, the Strength of Material Laboratory of Nanyang Technological University (NTU) is the venue where the student conducted all the experiments related to this project. There are three kinds of Split Hopkinson bar (SHB) apparatus in the laboratory. They are torsion, compression and Tensile SHB which used to obt…
In this study, in order to calculate dangerous volume at various stress distribution, the dangerous volume quantification method is proposed. And in order to predict stress distribution of spray coating, an easy calculation method of residual stress distribution based on the first report is proposed. The calculated da…
The D.C. electrical properties of poly (ethy lene oxide)/MgCl 2 composites were investigated as a function of different M gCl 2 filler concentrations (0, 5, 10, 15 and 20 wt.%) and different temperatures in the range (276-333) o K at three different polarizing fields. Resistivity: and dc Conductivity : σ dc were mea…
The foundation settlement affect is the reason of shell part disintegration and hinge forming in main supporting ribs in the heritage’s vaulted structure. The most theories consider masonry as interacting parts of rigid body. Simulation of hinge mechanism between two rotating masonry parts is performed in the present…
Solid-state lighting technology based on injection electroluminescence devices, light-emitting diode (LEDs) has the ability to operate with a long life typically in the order of 50,000 to 100,000 hours. Therefore, the global lighting community has no doubt that high-power LEDs will play an important role in general li…
The effects of the waste polyester fabric used as filler in natural rubber compound were studied. Six types of testing were conducted to determine the properties of waste polyester fabric used as filler in natural rubber compound such as the tensile testing, hardness test, resilience test, ageing test, density test an…
The interest in tissue engineered small diameter blood vessels was sparked off by \nthe need for cardiovascular grafts in surgeries. This project aims to fabricate a porous scaffold to allow the diffusion of nutrients and growth factors in a co-culture of smooth muscle and endothelial cells found in blood vessels. PCL…

Определены биохимические свойства субтилизиноподобной протеиназы Bacillus intermedius (AprBi), секретируемой рекомбинантным штаммом Bacillus subtilis в ранней и поздней стационарных фазах роста. Проведен анализ структуры белка и оценена его стабильность. Отмечено, что фермент, соответствующий разным фазам роста бактер…
During bioprocessing, there are many points at which protein can aggregate, reducing the overall protein refolding yield. A novel stimuli responsive polymer: Poly (L-lysine iso-phthalamide) was investigated in this study to examine its potential use as an additive to improve refolding yield of hen egg white lysozyme (…
Silylation is a surface imaging technique which allows silicon to absorb into photoresist in specified areas. Photoresist containing silicon creates a hard-mask which is resistant to oxygen plasma. This allows for the development process to occur strictly in dry etch systems. Surface imaging is a desirable technique b…
