Abstract : This program was focused on several novel experimental approaches to investigating charge injection and charge transport in organic semiconductors all using infrared (IR) spectroscopy. IR spectroscopy was employed to characterize polymer systems integrated in the architecture of organic field-effect transis…
Membran kitosan mempunyai efektivitas pemisahan relatif tinggi tetapi kestabilan mekanik rendah. Untuk meningkatkan kestabilan perlu ditambahkan silika sehingga dihasilkan membran kitosan-silika. Sebagai bahan dasar silika digunakan natrium silikat yang diisolasi dari abu sekam padi. Dalam pembuatan membran kitosan-si…
RADCONS Ver.1.0 (RADiological CONSequence Assessment Program) was developed for radiological risk assessment in this study. A Gaussian plume model was used to analyze the fate and transport of radionuclides released into the air in case of accidents. Both single meterological data and time series meterological data ca…
Polyhydroxyalkanoates (PHAs)는 다양한 미생물이 세포 내에 저장하는 에너지 저장물질로 생체적합성 플라스틱의 원료물질이다. 본 연구에서는 Cupriavidus necator를 사용하여 독립영양배양조건으로 poly(3-hydroxybutyrate) (P(3HB))를 생산함에 있어서 CO2 농도가 미생물의 성장과 P(3HB)의 축적에 미치는 영향을 확인하였다. 첫 번째 질소원을 포함한 배지에서의 6일 간의 배양 단계에서 C. necator의 균체수는 CO2 농도와 관계없이 증가했지만, 균체 내에 축적된 P(3HB)의 양은 CO2 농도가1-20%로 증…

Cheap catalysts for the photo-oxidation of water are needed for artificial photosynthesis. Polyoxotungstate anions incorporating catalytic metals such as ruthenium are known to catalyse the reaction, but are fragile. New work at Monash University and the Universities of New South Wales and Melbourne reveals that class…
Two novel compounds, 8–[2–(2–thienyl)vinyl]–10,10–dimethyl–10H–pyrido[1,2–a] indolium perchlorate (3a) and 8–[2–(5–phenyl–2–thienyl)vinyl]–10,10–dimethyl–10H–pyrido[1,2–a]indolium perchlorate (3b) were synthesized and characterized by IR,1H–NMR, elemental analyses, and X–ray diffraction. Crystal structural analysis su…
In the work a technology of tungsten films and two-layer copper-tungsten coatings deposition on stainless steel substrates was developed. The coatings were deposited by magnetron and arc sputtering of materials with condensation of them on the testing substrates. The deposition objects were probe of the ICRF antenna o…
Solid oxide fuel cells (SOFCs) are devices that convert chemical energy to electrical energy directly through electrochemical oxidation of a wide variety of fuels with high efficiency and low emissions. Recently, significant efforts have focused on lowering the operating temperature to enhance long-term stability and…
A bio-based epoxy derived from dehydroabietylamine was synthesized. In comparison, its petrochemical counterpart based on benzylamine was also prepared. Their chemical structures were confirmed in detail by Fourier Transform Infrared Spectra (FT-IR) and Nuclear Magnetic Resonance (1H-NMR and HSQC). The curing reaction…
The objective of this study is to quantify the effect of low amplitude cyclic stresses, such as those induced by environmental condition fluctuations and transportation, on multilayer paint systems found in works of art. A model was developed to establish criteria for damage, which take into account viscoelastic fatig…
Understanding the structural, dynamical and energetic basis of protein-protein interactions (PPIs) is key for a number of research disciplines. Predicting which sites in PPIs show potential for modulation with binding free energy (ΔG) calculations allows experimental work to be targeted and inhibitors to be rationally…
This report documents the technical basis for determining that stabilizing highpurity PuO{sub 2} derived from oxalate precipitation at the SRS HB-Line facility at a minimum of 625 {degree}C for at least four hours in an oxidizing atmosphere is equivalent to stabilizing at a minimum of 950 {degree}C for at least two ho…
This thesis describes the development of a new model for viscosity, the Enskog-2σ model. The model is based on Enskog theory in which the viscosity of a hard sphere fluid is computed from the hard sphere interactions on the molecular level. The idea of the Enskog-2σ model is to introduce two effective weakly temperatu…
Nanomaterial metrology is fundamental to understanding the physical properties of nanomaterials and their environmental interactions. Particles, in the nano and sub-micrometer regimes, are attractive materials for use in biomedical applications such as drug delivery and medical imaging. In order to address concerns re…
This work describes experiments conducted on GaAs/AlGaAs core-shell nanowires. The GaAs/AlGaAs materials system has been a major platform in the development of heterostructure devices. Heterostructure nanowires grown using bottom-up growth techniques are a means to creating high quality nanoscaled heterostructures wit…
