We report on a numerical study of the aspect-ratio dependency of Rayleigh-Benard convection, using direct numerical simulations. The investigated domains have equal height and width while the aspect ratio Gamma of depth per height is varied between 1/10 and 1. The Rayleigh numbers Ra for this ...
The synthesis of carbon nanostructures, with interesting morphologies, has created a revolution in nanotechnology; carbon nanotube is a case in point, but other nanoscale morphologies of graphitic carbon could provide compelling uses. In particular short structures, including very short nanotubes, have pr...
I am writing to you today with a humble request to consider bringing back the old 9:16 aspect ratio option. As a writer and content creator, this feature has been an integral part of my workflow, allowing me to create visually appealing and engaging content for various platforms, especially...

We present measurements of the normalized charge transport or Nusselt number Nu as a function of the aspect ratio Gamma for turbulent convection in an electrically driven film. In analogy with turbulent Rayleigh-Bénard convection, we develop the relevant theoretical framework in which we discuss the...
Electrostatically actuated microstructures with high-aspect-ratio laminated-beam suspensions have been fabricated using conventional CMOS processing followed by a sequence of maskless dry-etching steps. Laminated structures are etched out of the CMOS silicon oxide, silicon nitride, and aluminum layers. The...
Nirmalya Tripathy2, Min-Sang Ahn1 &Yoon-Bong Hahn1 This study demonstrates a highly stable, selective and sensitive uric acid (UA) biosensor based on high aspect ratio zinc oxide nanorods (ZNRs) vertical grown on electrode surface via a simple one-step low temperature solution route....

This paper presents a parametric geometry study of a thermal-fluid structure for single phase liquid cooling applications. Topology optimization results for an example two-dimensional system are first presented. The results of numerical experiments examining the influence of channel aspect ratio, i.e....
