Tailoring plasmonic substrates for SERS
… in research. Sphere segment void (SSV) substrates have been developed as reproducible, stable SERS substrates by electrodeposition of a metal through a colloidal template.<br/>The effect of adsorbing an organic monolayer on the surface of an SSV substrate was studied, which results in a …

Biogas production from novel substrates
… were sampled from a range of over 100 different substrates in Ireland including for first, second and third generation feedstocks. The C:N ranged from 81:1 (Winter Oats) to 7:1 (Silage Effluent). The BMP yields were recorded ranging from 38 ± 2.0 L CH4 kg−1 VS for pig slurry (weaning pigs) to 805 …

Thermoplastic bonding of microfluidic substrates
The assembly of microfluidic components for lab on a chip (LOC) applications that are manufactured from commodity thermoplastics is challenging. A survey of plastic welding techniques validates that contour transmission laser welding is the most viable and commercially demonstrated option for …

Directive antenna using metamaterial substrates
… performance of different metamaterial as antenna substrates, a structure is chosen to be optimized in such a way that it improves in radiation power, beamwidth, and bandwidth.

Oil sorption behavior of fibrous substrates
Oil spills such as the Deepwater Horizon Gulf of Mexico incident of 2010 are a threat to the ecosystem. In addition to the pollution caused due to the oil, synthetic sorbents are a hazard to the environment. Synthetic fibers like polypropylene occupy a major share of the oil spill cleanup industry. …

Proteome-Wide Prediction of Acetylation Substrates
… also report several novel non-histone acetylated substrates in S. cerevisiae. My approach, combined with more traditional experimental methods, may be useful for identifying additional proteins in the acetylome. Finally, in Chapter 4, I describe two bioinformatics approaches; one to predict …

CHARACTERIZATION OF DOPED GALLIUM NITRIDE SUBSTRATES
… The five GaN samples were grown on sapphire substrates by hydride vapor phase epitaxy (HVPE) and doped with different concentrations of iron, hydrogen, carbon, oxygen and silicon. The first step of characterization was measuring the optical absorption of all the samples using a UV-NIR fiber …

Theoretical studies of water on substrates
… Phys. 78, 420(1983)) indicates that on both substrates a water mono layer forms rapidly and with approximately the same nucleation rate. The present results give an order of magnitude larger value of J for the smooth substrate and hence imply that the latter forms a monolayer at lower vapor …

Electrical crosstalk in multilayer ceramic substrates
… were designed in both single and multilayer substrates in order to study crosstalk parameters such as line separation, line width, ground distance, ground type, and multilayer thickness. The mutual inductance and the mutual capacitance were calculated in order to use them in predicting …

Liquid crystal films confined between patterned substrates.
… liquid crystals confined between patterned substrates have been studied using molecular computer simulation. The aim of this work, done in parallel with experimentalists in Leeds, has been to investigate the use of chemical patterning as a novel method for controlling liquid crystal …

The Neural Substrates of Multisensory Speech Perception
<p>Comprehending speech is one of the most important human behaviors, but we are only beginning to understand how the brain accomplishes this difficult task. One key to speech perception seems to be that the brain integrates the independent sources of information available in the auditory and …

Sintering of metal nanoparticles on model substrates
… was deposited on single crystal metal-oxide substrates. The three metal-oxides examined were Pd on alpha-alumina, quartz (silica), and yttria stabilized zirconia. Palladium nanoparticles with an average size of around 15 nm were created from a thin film of deposited pure palladium. After the …

Graphene Decorated Substrates and Their Interfacial Characteristics
… vertically oriented 2D graphene petals on flat substrates serve as facile, unique template for high-density nanoparticle deposition. Such nanoparticle-decorated graphene petals are demonstrated to serve as promising substrates for surface enhanced Raman spectroscopy (using Ag nanoparticles) and …

Metallic thin film on SiGe/Si substrates
… Similar studies on Si(001) and Ge(001) substrates were also carried out for comparison. The Si0.8Ge0.2 VS remained stable in composition and unchanged in surface morphology below 500oC. Above 500oC, Ge desorbed from surface, leading to a decrease in Ge concentration and formation of …

Regulation of NEDD8/Rub1 and its substrates
… which then ultimately becomes conjugated to substrates that are normally ubiquitylated (Hjerpe et al., 2012a). Consequently, maintaining the ratio of NEDD8 to ubiquitin is important for maintaining the integrity of the ubiquitin pathway. <br/><br/>The mechanism by which the ubiquitin to NEDD8 …

Neural Substrates of Human Perceptual Decision-Making
Perceptual decision-making describes the process of choosing one of at least two response alternatives based on sensory evidence. This sensorimotor process underlies a range of human behaviours and has been studied extensively by both psychologists and neuroscientists. There is now a consensus, …

Reactivity of Aluminum Carbenoid with Unsaturated Substrates
Reactivity patterns of the β-diketiminate aluminum(I) complex NacNacAl towards a variety of unsaturated molecules were determined. Reaction of NacNacAl with one equivalent of benzophenone affords η2(C,O) adduct III-2 that undergoes cyclization reactions with benzophenone (III-3), aldimine (III-4), …

Zein films as substrates for cell attachment
… that the hydrophobicity and topography of substrates are important for cell attachment. Therefore, a secondary hypothesis was that the hydrophobicity and topography of zein substrates could be optimized for cancer cell attachment. The hydrophobicity of zein films had been observed to …
