Estimation of force produced by nickel-titanium superelastic archwires at large deflections

A method for estimating the absolute values of forces produced by nickel-titanium orthodontic wires at superelastic deformations is proposed. The method is based on both the elasticity theory and the experimental bending tests for the nickel-titanium wires. Forces for a number of nickel-titanium wires are calculated by this method.     

Laser Patterning of Aligned Carbon Nanotubes Arrays: Morphology,Surface Structure,and Interaction with Terahertz Radiation

The patterning of arrays of aligned multi-walled carbon nanotubes (MWCNTs) allows creating metastructures for terahertz (THz) applications. Here, the strips and columns from MWCNTs vertically grown on silicon substrates are prepared using CO₂ laser treatment. The tops of the patterned arrays are flat when the laser power is between 15 and 22 W, and craters appear there with increasing power. Laser treatment does not destroy the alignment of MWCNTs while removing their poorly ordered external layers. The products of oxidative destruction of these layers deposit on the surfaces of newly produced arrays. The oxygen groups resulting from the CO₂ laser treatment improve the wettability of nanotube arrays with an epoxy resin. We show that the patterned MWCNT arrays absorb the THz radiation more strongly than the as-synthesized arrays. Moreover, the pattern influences the frequency behavior of the absorbance.
