    • Continuum Approach to Self-Similarity and Scaling in Nanostructure Decay 

      Margetis, Dionisios; Aziz, Michael; Stone, Howard (American Physical Society, 2005)
      The morphological relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition temperature is studied analytically for diffusion-limited (DL) and attachment-detachment-limited (ADL) ...
    • Continuum Theory of Nanostructure Decay Via a Microscale Condition 

      Margetis, Dionisios; Fok, Pak-Wing; Aziz, Michael; Stone, Howard (American Physical Society, 2006)
      The morphological relaxation of faceted crystal surfaces is studied via a continuum approach. Our formulation includes (i) an evolution equation for the surface slope that describes step line tension, g<sub>1</sub>, and ...
    • Glycans pattern the phase behaviour of lipid membranes 

      Subramaniam, Anand; Guidotti, Guido; Manoharan, Vinothan N.; Stone, Howard (Springer Nature, 2012)
      Hydrated networks of glycans (polysaccharides)—in the form of cell walls, periplasms or gel-like matrices—are ubiquitously present adjacent to cellular plasma membranes. Yet, despite their abundance, the function of glycans ...
    • Grooving of a Grain Boundary by Evaporation–condensation below the Roughening Transition 

      Stone, Howard; Aziz, Michael; Margetis, Dionisios (American Institute of Physics, 2005)
      The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–condensation processes. ...
    • Magnetic Spheres in Viscous Flows and at Interfaces: Sorting, Coating, and Interfacial Deformation 

      Tsai, Scott (2013-02-11)
      Magnetic microparticles are often used in laboratory settings for the separation of biological material. These microparticles can also be useful in microfluidic settings because of their small size and the possibility of ...
    • Sheathless hydrodynamic positioning of buoyant drops and bubbles inside microchannels 

      Stan, Claudiu A.; Guglielmini, Laura; Ellerbee, Audrey K.; Caviezel, Daniel; Stone, Howard A.; Whitesides, George McClelland (American Physical Society (APS), 2011)
      Particles, bubbles, and drops carried by a fluid in a confined environment such as a pipe can be subjected to hydrodynamic lift forces, i.e., forces that are perpendicular to the direction of the flow. We investigated the ...
