    • Analyzing site selectivity in Rh2(esp)2-catalyzed intermolecular C-H amination reactions. 

      Bess, EN; DeLuca, RJ; Du Bois, J; Oderinde, MS; Roizen, Jennifer Lyn; Sigman, Matthew S; Tindall, DJ (J Am Chem Soc, 2014-04-16)
      Predicting site selectivity in C-H bond oxidation reactions involving heteroatom transfer is challenged by the small energetic differences between disparate bond types and the subtle interplay of steric and electronic effects ...
    • Dimensional study of the caging order parameter at the glass transition. 

      Charbonneau, Patrick; Ikeda, A; Parisi, G; Zamponi, Francesco (Proc Natl Acad Sci U S A, 2012-08-28)
      The glass problem is notoriously hard and controversial. Even at the mean-field level, little is agreed upon regarding why a fluid becomes sluggish while exhibiting but unremarkable structural changes. It is clear, however, ...
    • Hard-sphere crystallization gets rarer with increasing dimension. 

      Charbonneau, Benoit; Charbonneau, Patrick; Fortini, A; van Meel, JA (Phys Rev E Stat Nonlin Soft Matter Phys, 2009-12)
      We recently found that crystallization of monodisperse hard spheres from the bulk fluid faces a much higher free-energy barrier in four than in three dimensions at equivalent supersaturation, due to the increased geometrical ...
    • Highly parallel acoustic assembly of microparticles into well-ordered colloidal crystallites. 

      Owens, CE; Shields, CW; Cruz, DF; Charbonneau, Patrick; López, GP (Soft Matter, 2016-01-21)
      The precise arrangement of microscopic objects is critical to the development of functional materials and ornately patterned surfaces. Here, we present an acoustics-based method for the rapid arrangement of microscopic particles ...
    • Inside-out Z rings--constriction with and without GTP hydrolysis. 

      Erickson, Harold Paul; Osawa, Masaki (Molecular microbiology, 2011-07)
      The bacterial tubulin homologue FtsZ forms a ring-like structure called the Z ring that drives cytokinesis. We showed previously that FtsZ-YFP-mts, which has a short amphipathic helix (mts) on its C terminus that inserts ...
    • Modulating unimolecular charge transfer by exciting bridge vibrations. 

      Lin, Z; Lawrence, CM; Xiao, D; Kireev, VV; Skourtis, SS; Sessler, JL; Beratan, DN; ... (8 authors) (J Am Chem Soc, 2009-12-23)
      Ultrafast UV-vibrational spectroscopy was used to investigate how vibrational excitation of the bridge changes photoinduced electron transfer between donor (dimethylaniline) and acceptor (anthracene) moieties bridged by ...
    • Physical and economic potential of geological CO2 storage in saline aquifers. 

      Eccles, JK; Jackson, Robert; Newell, Richard G; Pratson, L (Environ Sci Technol, 2009-03-15)
      Carbon sequestration in sandstone saline reservoirs holds great potential for mitigating climate change, but its storage potential and cost per ton of avoided CO2 emissions are uncertain. We develop a general model to determine ...

    • Statistical analysis of crystallization database links protein physico-chemical features with crystallization mechanisms. 

      Barnum, TJ; Bruno, AE; Charbonneau, Patrick; Fusco, Diana; Luft, JR; Mukherjee, Sayan; Snell, EH (PLoS One, 2014)
      X-ray crystallography is the predominant method for obtaining atomic-scale information about biological macromolecules. Despite the success of the technique, obtaining well diffracting crystals still critically limits going ...
    • The kinase Grk2 regulates Nedd4/Nedd4-2-dependent control of epithelial Na+ channels. 

      Cook, DI; Dinudom, A; Fotia, AB; Kumar, S; Lefkowitz, Robert J; Young, JA (Proc Natl Acad Sci U S A, 2004-08-10)
      Epithelial Na(+) channels mediate the transport of Na across epithelia in the kidney, gut, and lungs and are required for blood pressure regulation. They are inhibited by ubiquitin protein ligases, such as Nedd4 and Nedd4-2, ...
    • Transition dynamics and magic-number-like behavior of frictional granular clusters. 

      Behringer, Robert P; Froyland, G; Tordesillas, A; Walker, DM; Zhang, J (Phys Rev E Stat Nonlin Soft Matter Phys, 2012-07)
      Force chains, the primary load-bearing structures in dense granular materials, rearrange in response to applied stresses and strains. These self-organized grain columns rely on contacts from weakly stressed grains for lateral ...
