      Wang, Suyun; Niu, Fenglin; Zhang, Guomin (2013)
      [1] East Asia is one of the most tectonically active regions on Earth's surface due to the collision from the India plate and the suctions induced by the subduction of the Pacific and Philippine plates. To better understand ...
    • Vertebrate seed dispersers maintain the composition of tropical forest seedbanks 

      Wandrag, E.M.; Dunham, A.E.; Miller, R.H.; Rogers, H.S. (2015)
      The accumulation of seeds in the soil (the seedbank) can set the template for the early regeneration of habitats following disturbance. Seed dispersal is an important factor determining the pattern of seed rain, which ...

    • Very strong Rydberg atom scattering in K(12p)–CH3NO2collisions: Role of transient ion pair formation 

      Kelley, M.; Buathong, S.; Dunning, F.B. (2017)
      Collisions between K(12p) Rydberg atoms and CH3NO2 target molecules are studied. Whereas CH3NO2 can form long-lived valence-bound CH3NO−2NO2− ions, the data provide no evidence for production of long-lived K+⋯⋯CH3NO−2NO2− ion ...
    • A viable Arabidopsis pex13 missense allele confers severe peroxisomal defects and decreases PEX5 association with peroxisomes 

      Woodward, Andrew W.; Fleming, Wendell A.; Burkhart, Sarah E.; Ratzel, Sarah E.; Bjornson, Marta; Bartel, Bonnie (2014)
      Peroxisomes are organelles that catabolize fatty acids and compartmentalize other oxidative metabolic processes in eukaryotes. Using a forward-genetic screen designed to recover severe peroxisome-defective mutants, we ...
    • Volcanic ash as a driver of enhanced organic carbon burial in the Cretaceous 

      Lee, Cin-Ty A.; Jiang, Hehe; Ronay, Elli; Minisini, Daniel; Stiles, Jackson; Neal, Matthew (2018)
      On greater than million year timescales, carbon in the ocean-atmosphere-biosphere system is controlled by geologic inputs of CO2ᅠthrough volcanic and metamorphic degassing. High atmospheric CO2ᅠand warm climates in the ...
    • Volcano-shape glycerol oxidation activity of palladium-decorated gold nanoparticles 

      Zhao, Zhun; Arentz, Joni; Pretzer, Lori A.; Limpornpipat, Pongsak; Clomburg, James M.; Gonzalez, Ramon; Schweitzer, Neil M.; Wu, Tianpin; Miller, Jeffrey T.; Wong, Michael S. (2014)
      Bimetallic PdAu catalysts are more active than monometallic ones for the selective oxidation of alcohols, but the reasons for improvement remain insufficiently detailed. A metal-on-metal material can probe the structure–catalysis ...
    • Voltage tuning of vibrational mode energies in single-molecule junctions 

      Li, Yajing; Doak, Peter; Kronik, Leeor; Neaton, Jeffrey B.; Natelson, Douglas (2014)
      Vibrational modes of molecules are fundamental properties determined by intramolecular bonding, atomic masses, and molecular geometry, and often serve as important channels for dissipation in nanoscale processes. Although ...
    • Wafer-scale monodomain films of spontaneously aligned single-walled carbon nanotubes 

      He, Xiaowei; Gao, Weilu; Xie, Lijuan; Li, Bo; Zhang, Qi; Lei, Sidong; Robinson, John M.; Hároz, Erik H.; Doorn, Stephen K.; Wang, Weipeng; Vajtai, Robert; Ajayan, Pulickel M.; Adams, W. Wade; Hauge, Robert H.; Kono, Junichiro (2016)
      The one-dimensional character of electrons, phonons and excitons in individual single-walled carbon nanotubes leads to extremely anisotropic electronic, thermal and optical properties. However, despite significant efforts ...
    • Water-structuring molecules and nanomaterials enhance radiofrequency heating in biologically relevant solutions 

      Lara, Nadia C.; Haider, Asad A.; Ho, Jason C.; Wilson, Lon J.; Barron, Andrew R.; Curley, Steven A.; Corr, Stuart J. (2016)
      For potential applications in nano-mediated radiofrequency cancer hyperthermia, the nanomaterial under investigation must increase the heating of any aqueous solution in which it is suspended when exposed to radiofrequency ...
    • The Weil-Peterson Hessian of Length on Teichmuller Space 

      Wolf, Michael (2012)
      We present a brief but nearly self-contained proof of a formula for the Weil-Petersson Hessian of the geodesic length of a closed curve (either simple or not simple) on a hyperbolic surface. The formula is the sum of the ...
    • Weyl–Kondo semimetal in heavy-fermion systems 

      Lai, Hsin-Hua; Grefe, Sarah E.; Paschen, Silke; Si, Qimiao (2018)
      While electronic states with nontrivial topology have traditionally been known in insulators, they have been evidenced in metals during the past 2 years. Such Weyl semimetals show topological protection while conducting ...
