A new design tested in experiments at SLAC National Accelerator Laboratory could improve plastic solar panel materials.
Scientists devised a new arrangement of solar cell ingredients, with bundles of polymer donors (green rods) and neatly organized carbon molecules, also known as fullerenes or buckyballs, serving as acceptors (purple, tan). (UCLA)

Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled.
Image - This illustration shows shape changes that occur in quadrillionths-of-a-second intervals in a ring-shaped molecule that was broken open by light. (SLAC)

An experiment at SLAC’s X-ray laser provides new insight into the ultrafast motions of a muscle protein in a basic biochemical reaction.
Image - This computerized rendering shows the 3-D structure of myoglobin, an oxygen-carrying protein found in many mammals’ muscles. The jagged green line represents a pulse of laser light that excites an iron atom (red sphere) at the core of the protein.

SLAC study of tiny nanocrystals provides new insight on the design and function of nanomaterials
Image - In this illustration, intense X-rays produced at SLAC's Linac Coherent Light Source strike nanowires to study an ultrafast "breathing" response in the crystals induced quadrillionths of a second earlier by pulses of optical laser light.

Scientists have for the first time mapped the atomic structure of a protein within a living cell. The technique, which peered into cells with an X-ray laser, could allow scientists to explore some components of living cells as never before.
Image - These micrograph images show rod-shaped bacterial cells suspended in pure water. The dark rectangular shapes inside the cells correspond to naturally occurring crystals within the cells.
