Comparative analysis on single- and multi-walled carbon nanotubes suspended for enhanced thermal energy transfer past stretching surfaces

AIP Advances
Flat and parabolic trough solar collectors concentrate sunlight onto a receiver tube containing the heat transfer liquid. Particularly, CNT nanofluids enhance the efficacy of energy harvesting in these systems.

Initial Buckling Behavior of Elastically Supported Rectangular FGM Plate based on Higher Order Shear Deformation Theory via Spline RBF Method [PDF]

Mechanics of Advanced Composite Structures
In the present paper, the effect of aspect ratio on the initial buckling response of an elastically supported rectangular FGM plate, the thin plate spline radial basis function (RBF) method can be used. This method involves the use of a thin plate spline
