Progress has made over the last several years in developing cleaner, more fuel-efficient vehicles. In particular, hybrid electric vehicles (HEVs) have helped reduce fuel emissions by using electrical power to power the vehicle. HEVs have been enhanced by the use of hybrid-energy-storage-systems (HESS), which use an ul…
322 Objectives [11C]DPA713 has been used to image translocator protein (TSPO) in humans and has four-fold difference in the affinity, measured in vitro, between high- (HABs) and low-affinity binders (LABs). To assess the utility of [11C]DPA713 in different genotypes, we performed quantification in both regional and vo…
1795 Objectives Synaptic vesicle protein 2A (SV2A) has been identified as an interesting therapeutic and imaging target for epilepsy and other neurologic disorders. Herein, we report the first radiosynthesis of 11C-levetiracetam (11C-LEV) and its preliminary evaluation for PET imaging of SV2A expression. Methods The m…
Sympathetic detonation of high explosives occurs when a detonating donor initiates neighboring acceptor. The present study focused on one-on-one sympathetic detonation employing 155 mm high explosive filled with PBXN-109 using 2D a hydrodynamics. The unbuffered and buffered sympathetic detonations were simulated while…
Salah satu cara untuk meningkatkan aktivitas fotokatalitik suatu material katalis adalah dengan melapiskan material katalis Titanium dioksida (TiO2) pada permukaan polimer yang berukuran cukup besar, ringan, transparan dan bersifat termoplastik. Untuk memilih jenis polimer terbaik sebagai material penyangga katalis, d…

Chemical reactions can be understood as transitions from basin to basin on a high dimensional potential energy landscape. Varying temperature only changes the average kinetic energy of the system. While applying voltages or external pressures directly tilts the landscape and drives the reactions in desired directions.…
Abstract : A silica/electro-optic (EO) polymer phase modulator is proposed for millimeter-wave (MMW) radiation receiver with the use of a bowtie antenna. Waveguide design optimization is presented for a waveguide with an EO polymer core and silica/solgel cladding. Electrode effects on the insertion loss and poling eff…
This thesis reports computational studies about protein-ion binding in part I, and optical properties of organic materials in part II. It is very difficult to investigate a whole protein computationally. So here I proposed smaller models to probe protein-ion binding: a short triple helix (triple chain), a short peptid…
Atom probe tomography is a high resolution microscopy technique capable of determining the 3D location and chemical identification of individual atoms within a specimen. Though it is becoming ever more popular, a number of issues with the technique are known. First, the large amount of data created by atom probe tomog…
The aim of this thesis is to design and build a torsional Kolsky bar apparatus for testing cylindrical specimens in torsion at high strain-rates.In addition to well-established designs, this testing apparatus will include a conical mirror combined with a high speed camera that allows time-resolved optical observation…
Silicon (Si)-based materials have recently emerged as a promising candidate for anodes in lithium-ion batteries because they exhibit much higher energy-storage capacities than the conventional graphite anode. However, the practical use of Si is hampered by its poor cycleability; during lithiation, Si forms alloys with…
Despite the widespread interest in graphene electronics over the last decade, high-performance graphene field-effect transistors (GFETs) on flexible substrates have been rarely achieved, even though this atomic sheet is widely understood to have greater prospects for flexible electronic systems. In this work, we inves…
\nW artykule przedstawiono wyniki badań złączy wykonanych metodą MAG w osłonach różnych mieszanek gazowych. Stwierdzono, że osłona gazowa oraz rodzaj transportu materiału w łuku powodują różną głębokość wtopienia, wielkość strefy wpływu ciepła oraz twardość uzyskanych złączy. Ze względu na złożoność czynników wpływają…

The measurements of ultrasonic wave velocity and density of ternary mixtures: electrolyte-urea-water and quaternary mixtures electrolyte-urea-water-ethanol with AlCl3, Al(NO3)3, MgCl2 and NaCl as electrolytes have been carried out in the temperature range of 15 to 35°C. Analysis of the results indicates that urea mole…
The thermal conductivity of thin Germanane (GeH) layers was measured using suspended micro-devices with integrated heaters and thermometers. The thermal contact resistance of the GeH samples suspended on the measurement devices was determined from the measured thermal resistance values of samples with different suspen…
Cell-based approaches to improve blood perfusion are promising for treatment of peripheral arterial disease (PAD). However, cell delivery alone is limited by poor cell survival and the lack of organization among newly formed vessels. We hypothesized that parallel-aligned nanofibrillar scaffolds may guide endothelial c…
LaNiO3films were prepared through the metal organic deposition method using La(NO3)·4H2O and Ni(CH3COO)2·4H2O as starting materials, acetylacetone as a complexing agent, and 2-methoxyethanol as a solvent. The effect of the annealing atmosphere and ion stoichiometry on the film conductivity was examined. The results sh…
ZnO thin films with the thickness of about 15nm on (0001) substrates were prepared by pulsed laser deposition. X-ray photoelectron spectroscopy indicated that both as grown and then annealed ZnO thin films were oxygen rich. Hydrogen (H2) sensing measurements of the films indicated that the conductivity type of both th…
