This article reviews the static and dynamic properties of spontaneous superstructures
formed by electrons. Representations of such electronic crystals are charge density waves …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

Most people are familiar with the fact that diamond and graphite are both composed only of
carbon; yet they have very different properties which result from the very different structures …

Ferroelectricity results from one of the most representative phase transitions in solids, and is
widely used for technical applications. However, observations of ferroelectricity in organic …

Block copolymer micelles are water-soluble biocompatible nanocontainers with great
potential for delivering hydrophobic drugs. An understanding of their cellular distribution is …

We report the direct observation by x-ray diffraction of a photoinduced paraelectric-to-
ferroelectric structural phase transition using monochromatic 100-picosecond synchrotron …

Ferroelectric polarization of 6.3 μ C cm-2 is induced by the neutral-to-ionic transition, upon
which nonpolar molecules of electron donor tetrathiafulvalene (TTF) and acceptor p …

We demonstrate that the cooperative charge transfer among constructive molecules in
organic crystals of tetrathiafulvalene-chloranil, ie, the bidirectional transition between the …

Tetrathiafulvalene (TTF) as the prototypical electron donor for solid-state (electronics)
applications is converted to the unusual cation-radical salt, TTF+• CB-(where CB-is the non …

In conventional ferroelectrics the polarization is induced either by the relative displacement
of positive and negative ions due to a lattice distortion or by the collective alignment of …
