TL;DR: The purpose of this short review paper is to illustrate the possibility to amorphize one compound by several different routes and to rationalize the observed transformations using the concepts of effective temperature introduced in nonequilibrium physics.

TL;DR: It is shown that decreasing the milling temperature leads to an increase of the amorphization tendency whereas milling above T(g) can produce a crystal-to-crystal transformation between polymorphic varieties, contradict the usual suggestion that milling transforms the physical state only by a heating effect which induces a local melting.

TL;DR: The structural properties resulting from the reciprocal influence between water and three well-known homologous disaccharides in aqueous solutions have been investigated by means of molecular dynamics computer simulations and suggest that trehalose-water mixtures would be more homogeneous than the two others, thus reducing both desiccation stresses and ice formation.

TL;DR: The structural properties of trehalose, maltose and sucrose in aqueous solutions have been investigated in the 4-66 wt % concentration range by means of molecular dynamics computer simulations as mentioned in this paper.

TL;DR: By performing molecular dynamics simulations of binary Lennard-Jones systems with three different potentials, it is shown that the increase of anharmonicity and capacity for intermolecular coupling of the potential is the cause of the increase in kinetic fragility and nonexponentiality in the liquid state and the T(g)-scaled temperature dependence of the nonergodicity parameter determined by the vibrations at low temperatures in the glassy state.
