Soft solids consisting of two bicontinuous, immiscible solvents separated by a tortuous membrane of small solid particles have been predicted as novel reaction media. Experimental demonstration of these materials is possible by careful treatment of the particles' surfaces.
The vortex in a stirring solution of supramolecular fibres is shown to induce chirality in an originally achiral system. The chiral sense is reversible and can be switched by changing the direction of stirring.
Conventional metamaterials that show negative refraction suffer from high intrinsic losses and are difficult to fabricate. A novel anisotropic semiconducting metamaterial offers a solution.
Transition metal oxides show many interesting phenomena from high-Tc superconductivity to colossal magnetoresistance and multiferroicity, triggering intensive studies. However, we have barely tapped into their potential for applications.
Comparison of the vibrations of a quasicrystal with those of a conventional crystal opens the way to a better understanding of the consequences of aperiodicity on the properties of quasicrystals.
