A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

Oxygen, which supports all aerobic life, is produced by photosynthetic water oxidation in
plants, algae, and cyanobacteria. The water-oxidation reaction probably first appeared in …

A Perspective is presented on the history and current understanding of molecular gels and
the factors that must be considered to characterize them. The abilities of the most important …

Biological water oxidation, performed by a single enzyme, photosystem II, is a central
research topic not only in understanding the photosynthetic apparatus but also for the …

Oxygenic photosynthesis forms the basis of aerobic life on earth by converting light energy
into biologically useful chemical energy and by splitting water to generate molecular oxygen …

The investigation of water oxidation in photosynthesis has remained a central topic in
biochemical research for the last few decades due to the importance of this catalytic process …

Protein crystallography using synchrotron radiation sources has had a tremendous impact
on biology, having yielded the structures of thousands of proteins and given detailed insight …

Intense femtosecond x-ray pulses produced at the Linac Coherent Light Source (LCLS)
were used for simultaneous x-ray diffraction (XRD) and x-ray emission spectroscopy (XES) …

Tetrapyrrole-containing proteins are one of the most fundamental classes of enzymes in
nature and it remains an open question to give a chemical rationale for the multitude of …
