Superelastic Nickel-titanium Wires
British Journal of Orthodontics, 1992Superelastic nickel-titanium archwires, unlike conventional wires, are capable of withstanding very large deflections and on returning to their original shape on deactivation will produce more moderate forces. The region over which there is a 'plateau' depends on the deflection and is greater the larger the deflection.

Network Modulus and Superelasticity
Macromolecules, 1994We discuss the elastic modulus G and swelling/deswelling behavior of networks as a function of their concentration 4 and their preparation state. Simple scaling ideas reproduce the prediction of James and Guth for the modulus of networks swollen in a 8 solvent (G - 4113) but lead to a new prediction in a good solvent (G - 4'/12).

Superelastic Hard Carbon Nanofiber Aerogels
Advanced Materials, 2019AbstractSuperelastic carbon aerogels have been widely explored by graphitic carbons and soft carbons. These soft aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbon aerogels show great advantages in mechanical strength and structural stability due to the sp3‐C‐induced turbostratic “house‐of ...

A Superelastic Helicotome for Capsulorhexis
2019We design and characterize a novel, single-use device to perform capsulorhexis, a critical step during cataract surgery, during which a 5-mm-diameter incision is made in the anterior lens capsule. This device, the Helicotome, is a hand-held tool based on a superelastic shape-memory-alloy blade to perform the circular incision in the lens capsule.

Superelastic softening in perovskites
Physical Review B, 2011Contrary to high frequency (MHz-GHz) elastic data, at low frequencies (0.1-50 Hz) huge elastic softening (superelasticity) is usually found in the low symmetry improper ferroelastic phases (i.e., tetragonal or rhombohedral) of perovskite structured materials including SrTiO3, KMn1-xCaxF3, and LaAlO3.

2018We design and characterize a novel, single-use device to perform capsulorhexis, a critical step during cataract surgery, during which a 5 mm diameter incision is made in the anterior lens capsule. This device, the Helicotome, is a handheld tool based on a superelastic shape-memory-alloy blade to perform the circular incision in the lens capsule.

Micropolar elastic percolation: The superelastic problem
Physical Review B, 1988This paper deals with the critical elastic behavior of a two-dimensional micropolar (or "granular") network with randomly rigid or elastic bonds. It presents a new derivation of Feng's inequalities $1l{s}^{\ensuremath{'}}ls$ in the context of micropolar elasticity (where $s$ is the conductivity exponent, ${s}^{\ensuremath{'}}$ the elastic-moduli ...
