Physical vapour deposition (PVD) is used to grow millimetre-long Bi2Te3 sub-micron belts catalysed by TiO2 nanoparticles. The catalytic efficiency of TiO2 nanoparticles for the nanostructure growth is compared with the catalyst-free growth employing scanning electron microscopy. The catalyst-coated and catalyst-free substrates are arranged side-by-side, and overgrown at the same time, to assure...

of a dissertation at the University of Miami. Dissertation supervised by Professor Brian Mapes. No. of pages in text. (103) The annual rainfall cycle in the Caribbean is characterized by a bimodal pattern with peaks in the late spring (“early rainfall season”) and late summer (“late rainfall season”) with a mid-summer minimum (“mid-summer drought”). The time average rainfall pattern during the ...

We continue to upgrade our planetary radiation transfer (RT) model based on MODTRAN5 to spectrally characterize the RT of planetary atmospheres. A key objective of our project is to develop a code that can be used by astronomers and planetary scientists in the search for planets in other star systems, or ‘exoplanets’. Already 373 gas giants have been detected orbiting 215 stars, but no terrestr...

Zonal ‡ow helps reduce the turbulent transport level in tokamaks. Rosenbluth and Hinton have shown that zonal ‡ow damps to to a non-vanishing residual level in collisionless and collisional banana regime plasmas Recent zonal ‡ow advances are summarized including the evaluation of the e¤ects on this zonal ‡ow residual of plasma cross section shaping, shorter wavelengths including those less than...

fast and unplanned city growth, has effects such as isolation of village societies, threatening urbancores and centers and small and weak societies, destruction of open spaces and open and natural regions. smart growthoffers a sustainable way for urban developing with appropriate use of available sources, increase of urban services,developing neighborhoods with different uses, making public tra...
