Wavelength tunability of ion-bombardment-induced ripples on sapphire
Hua Zhou,Yiping Wang,Lan Zhou,Randall L. Headrick,Ahmet S. Ozcan,Yiyi Wang,Gozde Ozaydin,Karl F. Ludwig,D. Peter Siddons +8 more
TL;DR: In this paper, a study of ripple formation on sapphire surfaces by ion bombardment is presented, and it is shown that the wavelength can be varied over a remarkably wide range by changing the ion incidence angle.
Diamond crystal X-ray optics for high-power-density synchrotron radiation beams
Lonny E. Berman,Jerome B. Hastings,D. Peter Siddons,Masaki Koike,Vivian Stojanoff,Michael Hart +5 more
TL;DR: In this paper, a man-made perfect single crystal isotopically-enriched diamond is demonstrated to be an excellent X-ray monochromator even when subjected to the highest incident power density expected at third-generation synchrotron source undulator beam lines.

Insights into molecular chemistry of Chiapas amber using infrared-light microscopy, PIXE/RBS, and sulfur K-edge XANES spectroscopy
Francisco Riquelme,Paul Northrup,José Luis Ruvalcaba-Sil,Vivian Stojanoff,D. Peter Siddons,Jesús Alvarado-Ortega +5 more
TL;DR: PIXE/RBS data were combined with complementary K-edge XANES spectroscopy (X-ray absorption near-edge structure) to identify the amount of sulfur in Chiapas amber as discussed by the authors.

Protein crystal movements and fluid flows during microgravity growth
T. J. Boggon,Naomi E. Chayen,Edward H. Snell,Jun Dong,Jun Dong,Peter Lautenschlager,L. Potthast,D. Peter Siddons,Vivian Stojanoff,Elspeth Gordon,Andrew Thompson,P.F. Zagalsky,Ru–Chang Bi,John R. Helliwell +13 more
TL;DR: The growth of protein crystals suitable for x-ray crystal structure analysis is an important topic as mentioned in this paper and the quality (perfection) of protein crystal is now being evaluated by mosaicity analysis (rocking curves) and topographic images as well as the diffraction resolution limit and overall data quality.
