Catalytic Nanomotors: Autonomous Movement of Striped Nanorods
Walter F. Paxton,Kevin C. Kistler,Christine C. Olmeda,Ayusman Sen,Sarah K. St. Angelo,Yanyan Cao,Thomas E. Mallouk,Paul E. Lammert,Vincent H. Crespi +8 more
TL;DR: By solving the convection-diffusion equation in the frame of the moving rod, it was found that the interfacial tension force scales approximately as SR(2)gamma/muDL, where S is the area-normalized oxygen evolution rate, gamma is the liquid-vapor interfacial pressure, R is the rod radius, mu is the viscosity, D is the diffusion coefficient of oxygen, and L is the length of the rod.
Journal ArticleDOI
Catalytic Motors for Transport of Colloidal Cargo
TL;DR: It is demonstrated that catalytic Pt-Au nanomotors can transport a prototypical cargo: polystyrene microspheres and motors with Ni segments can overcome both Brownian orientational fluctuations and biased rotation of the rod-sphere doublet to enable persistent steerable uniaxial motion in an external magnetic field.
Journal ArticleDOI
Crystallites of magnetic charges in artificial spin ice
Sheng Zhang,Ian Gilbert,Cristiano Nisoli,Gia-Wei Chern,M. J. Erickson,Liam O'Brien,Liam O'Brien,Chris Leighton,Paul E. Lammert,Vincent H. Crespi,Peter Schiffer +10 more
TL;DR: Here it is demonstrated a method for thermalizing artificial spin ices with square and kagome lattices by heating above the Curie temperature of the constituent material, which achieves unprecedented thermal ordering of the moments.
Journal ArticleDOI
Plastic Deformations of Carbon Nanotubes
TL;DR: In this article, the onset of plastic deformation depends very strongly on the wrapping index of a carbon nanotube, and it is shown that the deformation rate depends on the degree of deformation.
Journal ArticleDOI
Selectively manipulable acoustic-powered microswimmers
Daniel Ahmed,Mengqian Lu,Amir Nourhani,Paul E. Lammert,Zak Stratton,Hari S. Muddana,Vincent H. Crespi,Tony Jun Huang +7 more
TL;DR: The swimmer design overcomes the commonly-held design paradigm that microswimmers must use non-reciprocal motion to achieve propulsion; instead, the swimmer is propelled by oscillatory motion of an air bubble trapped within the Swimmer's polymer body.
