Elasticity of spheres with buckled surfaces
Yingzhen Tian, Megan McCarthy, Megan King +1
The buckling instabilities of core-shell systems, comprising an interior elastic sphere, attached to an exterior shell, have been proposed to underlie myriad biological morphologie…
X-ray Near Field Speckle: Implementation and Critical Analysis
Xinhui Lu, Simon GJ Mochrie, S. Narayanan +2
We have implemented the newly-introduced, coherence-based technique of x-ray near-field speckle (XNFS) at 8-ID-I at the Advanced Photon Source. In the near field regime of high-bri…
Dynamics of colloidal particles in ice
Melissa Spannuth, S. G. J. Mochrie, S. S. L. Peppin +1
We use X-ray Photon Correlation Spectroscopy (XPCS) to probe the dynamics of colloidal particles in polycrystalline ice. During freezing, the dendritic ice morphology and rejection…
Biomimetic isotropic nanostructures for structural coloration
Jason D. Forster, Heeso Noh, Seng Fatt Liew +9
We describe the self-assembly of biomimetic isotropic films which display structural color amenable to potential applications in coatings. Isotropic structures can produce color if…
How a liquid becomes a glass both on cooling and on heating
Xinhui Lu, S. G. J. Mochrie, S. Narayanan +2
The onset of structural arrest and glass formation in a concentrated suspension of silica nanoparticles in a water-lutidine binary mixture near its consolute point is studied by ex…
Evolution of particle-scale dynamics in an aging clay suspension
R. Bandyopadhyay, D. Liang, H. Yardimci +5
Multispeckle x-ray photon correlation spectroscopy was employed to characterize the slow dynamics of a colloidal suspension formed by highly-charged, nanometer-sized disks. At scat…
