The establishment of covalent junctions between carbon nanotubes (CNTs) and the modification of their straight tubular morphology are two strategies needed to successfully synthesize nanotube-based three-dimensional (3D) frameworks exhibiting superior material properties. Engineering such 3D structures in scalable synthetic processes still remains a(More)
Conventional adhesives show a decrease in the adhesion force with increasing temperature due to thermally induced viscoelastic thinning and/or structural decomposition. Here, we report the counter-intuitive behaviour of carbon nanotube (CNT) dry adhesives that show a temperature-enhanced adhesion strength by over six-fold up to 143 N cm-2 (4 mm × 4 mm),(More)
This paper presents a numerical investigation for natural convection of air in a three dimensional inclined annulus enclosure. This study wills exam the effect of radius ratio of an annulus made from graphite/epoxy laminated composite material on heat transfer taking two types of optimization of effective thermal conductivity in consideration: minimization(More)
Non-uniform heat flux generated by microchips causes " hot spots " in very small areas on the microchip surface. These hot spots are generated by the logic blocks in the microchip bay; however, memory blocks generate lower heat flux in contrast. The goal of this research is to design, fabricate, and test an active cooling, micro-channel heat sink device(More)
