Optical Antenna Photovoltaics & Making Metallic Nano-rods
… an array of vertically aligned metallic nano-rods (MNR). Porous aluminum oxide (PAO) is used as a nano-structured template for growth of the MNR. PAO exhibit vertically aligned pores (D = 20 - 200nm) in a densely packed hexagonal arrangement. MNR fabrication is achieved through templated …

Residual stress evaluation of aluminium drill rods
… in extruded high strength aluminium drill rods. These drill rods were manufactured by Hulett Aluminium for the mining industry for surface drilling exploration work. Initially a review of available residual stress measurement techniques was undertaken to establish which technique was the …

Coiling of elastic rods on rigid substrates
We investigate the deployment of a thin elastic rod onto a rigid substrate and study the resulting coiling patterns. In our approach, we combine precision model experiments, scaling analyses, and computer simulations towards developing predictive understanding of the coiling process. Both cases of …

Mechanical behavior of elastic rods under constraint
… investigation of the mechanics of thin elastic rods under a variety of loading conditions. Four scenarios are explored, with increasing complexity: i) the shape of a naturally curved rod suspended under self-weight, ii) the buckling and post-buckling behavior of a rod compressed inside a …

Simulation of Microwave Heating of Mullite Rods
Microwave processing has been studied as an alternate heating technique over conventional heating for industrial applications. Some advantages include quicker and more uniform heating. Also, microwave energy offers the advantage of localized heating and smaller-sized equipment. Many ceramics, …

Waves on Elastic Rods and Helical Spring Problems
… traveling wave propagation on uniform elastic rods with constant curvature and torsion, i.e. a straight rod and a helical rod. The first set of problems concerns planar traveling loop-like waves on intrinsically straight rods. It is shown that loops with compact support can exist on homogeneous …

Actin dynamics in silico, in waves, and in rods
… of cofilin and actin known as cofilin-actin rods (or rods). Using glutamate excitotoxicity as a model system for the cofilin pathology observed in Alzheimer disease (AD), we have determined signaling mechanisms for cofilin-actin rod induction, which in young rat hippocampal neurons require …

FEM simulation of ultrasonic wave propagation in solid rods
… ultrasonic wave propagation in solid cylindrical rods. In this study, both experimental investigations and theoretical analyses are conducted. In the experiment, the 4.2 mm diameter center wire of the commonly used Grad 250 7-wire strand have been employed as the specimen and all the specimens are …

Structure formation and fractionation in systems of colloidal rods
Nowadays, colloidal rods can be synthesized in large amounts. The rods are typically cylindrically and their length ranges from several nanometers to a few micrometers. In solution, systems of colloidal rodlike molecules or aggregates can form liquid-crystalline phases with long-range orientational …

Thermomechanics of helical strands and helical-fiber-reinforced rods
Helical strands, or helically wound cables, are made of layers of individual wires wrapped around a common central axis. They are seen in ropes and power transmission cables. Similar structures are also present in biological tissues in the form of helical fiber reinforced composites. Regardless of …

Confined wrinkling of thin elastic rods, sheets and cones
… with a central hole, cone and conical frustum. Rods and planar sheets are initially buckled into their first mode by applying a small axial displacement. Confinement is achieved by placing the buckled sheet between two parallel rigid plates, which are gradually moved towards each other until the …

Nondestructive evaluation of composite rods using ultrasonic wave propagation
… a detailed analysis of advanced composite rods (comprised of two or more distinct axial sections of different materials) using theoretical ultrasonic NDE. In anticipation of the high elastic moduli of the rods (relative to many metals) along their longitudinal axes, a one-dimensional wave …
