    The effects of Clostridium perfringens α-toxin on host cells have previously been studied extensively but the biophysical processes associated with toxicity are poorly understood. The work reported here shows that the ...
  • Cloudless atmospheres for L/T dwarfs and extra-solar giant planets 

    Tremblin, Pascal; Amundsen, David S.; Chabrier, G.; Baraffe, I.; Drummond, B.; Hinkley, Sasha; Mourier, P.; Venot, O. (American Astronomical Society, 2016-01-28)
    The admitted, conventional scenario to explain the complex spectral evolution of brown dwarfs (BD) since their first detections twenty years ago, has always been the key role played by micron-size condensates, called "dust" ...
  • CO abundance variations in the Orion molecular cloud 

    Ripple, F; Heyer, MH; Gutermuth, R; Snell, RL; Brunt, CM (Oxford University Press, 2013-03-19)

  • Coexisting Nematic and Smectic- A Phases in a Twisted Liquid-Crystal Cell 

    Ruan, Lizhen; Osipov, M. A.; Sambles, J. Roy (American Physical Society, 2001)
    Twisted homogeneously planar-aligned nematic liquid-crystal cells are cooled into the smectic- A phase. The expected defective structure does not form. Instead the cells still show good optical-guiding characteristics. ...
  • Coherence and measurement in quantum thermodynamics 

    Anders, Janet (Nature Publishing Group, 2016-02-26)
    Thermodynamics is a highly successful macroscopic theory widely used across the natural sciences and for the construction of everyday devices, from car engines to solar cells. With thermodynamics predating quantum theory, ...
