Fragile-to-strong crossover in supercooled liquids remains elusive.
Transport properties of glass forming liquids change markedly around an onset temperature To. For temperatures T above To, these properties depend little with T , while for T < To these properties are super -Arrhenius – varying faster than exponentially in 1/T . Upon lowering temperature significantly further, theory [1] predicts that reversible transport in a supercooled liquid, if it can be o...
متن کاملFragile-to-strong crossover coupled to the liquid-liquid transition in hydrophobic solutions.
Using discrete molecular dynamics simulations we study the relation between the thermodynamic and diffusive behaviors of a primitive model of aqueous solutions of hydrophobic solutes consisting of hard spheres in the Jagla particles solvent, close to the liquid-liquid critical point of the solvent. We find that the fragile-to-strong dynamic transition in the diffusive behavior is always coupled...
متن کاملExperimental evidence of fragile-to-strong dynamic crossover in DNA hydration water.
We used high-resolution quasielastic neutron scattering spectroscopy to study the single-particle dynamics of water molecules on the surface of hydrated DNA samples. Both H(2)O and D(2)O hydrated samples were measured. The contribution of scattering from DNA is subtracted out by taking the difference of the signals between the two samples. The measurement was made at a series of temperatures fr...
متن کاملThe fragile-to-strong dynamical crossover and the system viscoelasticity in attractive glass forming colloids
The dynamical arrest phenomena of an adhesive hard-sphere (AHS) colloid, L64-D2O system has been studied by using calorimetry and the complex shear modulus. This system is characterized by a rich temperature (T ) and volume fraction (φ) phase diagram with a percolation line (PT). According to the modecoupling theory (MCT), a cusp-like singularity and two glassy phases, one attractive (AG) and o...
متن کاملObservation of fragile-to-strong dynamic crossover in protein hydration water.
At low temperatures, proteins exist in a glassy state, a state that has no conformational flexibility and shows no biological functions. In a hydrated protein, at temperatures greater-- similar 220 K, this flexibility is restored, and the protein is able to sample more conformational substates, thus becoming biologically functional. This "dynamical" transition of protein is believed to be trigg...
