Three-dimensional mapping of a deformation field inside a nanocrystal
Article Abstract:
Coherent X-ray diffraction imaging is a form of microscopy in which diffraction patterns can be inverted to obtain full three-dimensional images of the interior density within nanocrystals, which also reveals a real-space phase that is consistent with the three-dimensional evolution of a deformation field arising from interfacial contact forces. This method represents a vital step towards the ultimate goal of atomic resolution single-molecule imaging that justifies development of X-ray free electron lasers.

Strained silicon as a new electro-optic material
Article Abstract:
A significant linear electro-optic effect was induced in silicon by breaking the crystal symmetry using silicon nitride glass [[Si.sub.3][N.sub.4]] as a straining layer. The symmetry is broken by depositing a straining layer on top of a silicon waveguide, and the induced nonlinear coefficient, makes it possible to realize a silicon electro-optic modulator.

Discovery of the progenitor of the type Ia supernova 2007on
Article Abstract:
Two families of progenitor models are employed to study the discovery of a new object at the position of the Ia supernova (2007on) in the elliptical galaxy NGC 1404. The X-ray source is found to act as the progenitor of the supernova, favoring its accretion model in all aspects.
