Turning a new magnetic leaf
Researchers have used a leaf as a template to produce a complex, hierarchical structure from the magnetic and conductive material iron carbide. X-ray powder diffraction allowed them to reveal how the biological template was able to create an intricate vascular structure in a ceramic product.

Kicking around solar cell materials
Sheffield's David Lidzey working with Athene Donald of the University of Cambridge and experts from Cardiff University and Nick Terrill at the Diamond Light Source, the UK's synchrotron facility in Didcot, have investigated the structure of solar cell materials to help them improve photovoltaic efficiencies.

Calculation of effective penetration depth in X-ray diffraction for pharmaceutical solids
[registered users only]
A method has been developed to define X-ray penetration depth based on the signal detection limits of the X-ray diffractometer and empirically verified using bilayer compacts of varying known thicknesses of mannitol and lactose.
