Emergent superconductivity in an iron based honeycomb lattice initiated by pressure driven spin crossover

Nat Commun
PMCID: 5953925
PMID: 29765049
DOI: 10.1038/s41467-018-04326-1

[…] The 2D XRD patterns were integrated using the Dioptas program. Unit cell parameter refinements were performed with FULLPROF program. The quantitative analyses of the XES data were carried out through IAD (IAD method). […]


Valence and spin states of iron are invisible in Earth’s lower mantle

Nat Commun
PMCID: 5876394
PMID: 29599446
DOI: 10.1038/s41467-018-03671-5

[…] ray beam were calibrated by 1 bar diffraction of LaB6. At intervals of 1–2 GPa, XRD images of the samples were recorded for an exposure time of 60 s. The XRD images were integrated using the software DIOPTAS. Diffraction patterns were analyzed using the software FullProf to examine the crystal structure and extract lattice parameters.The compression curve of our Bdg sample exhibits softening betwe […]


Experimental evidence of low density liquid water upon rapid decompression

Proc Natl Acad Sci U S A
PMCID: 5834690
PMID: 29440411
DOI: 10.1073/pnas.1716310115

[…] process with a PILATUS 1M-F detector. The typical exposure time was from 5 s to 7 ms, depending on decompression rate and temperature. Diffraction data were analyzed and integrated using the software Dioptas (). In the background subtraction, we used a diffraction image of crystalline ice-VIII as background to obtain a clear diffraction pattern of the low-density noncrystalline phase and ice-Ic () […]


Rapid Growth of Nanocrystalline Diamond on Single Crystal Diamond for Studies on Materials under Extreme Conditions

Sci Rep
PMCID: 5780477
PMID: 29362393
DOI: 10.1038/s41598-018-19915-9

[…] hoton Source, Argonne National Laboratory beam-line 16-ID-B. The monochromatic X-rays utilized in the diffraction experiments had a wavelength λ = 0.4066 Å. The image plate data were integrated using DIOPTAS.The tungsten equation of state for pressure calibration was obtained from the shock data of Hixson et al. by fitting the third order Birch-Murnaghan equation to the pressure-volume (P-V) isoth […]


Topologically frustrated ionisation in a water ammonia ice mixture

Nat Commun
PMCID: 5648802
PMID: 29051485
DOI: 10.1038/s41467-017-01132-z

[…] e filtered by a multichannel collimator to reduce the large contribution originating from the Compton scattering of the diamond anvils. Integration of the X-ray images was performed with the fit2D or Dioptas software programs. High-pressure neutron-diffraction experiments were carried out using the V7 Paris-Edinburgh press on the PEARL station of the ISIS spallation neutron source at the Rutherfor […]


One dimensional diamondoid polyaniline like nanothreads from compressed crystal aniline

PMCID: 5869312
PMID: 29629095
DOI: 10.1039/c7sc03445h

[…] .3738 Å, a MARCCD 165 detector positioned at 146 mm from the sample, as calibrated with a CeO2 standard. The focal spot (fwhm) of the beam was ∼3 μm. The 2D diffraction patterns were integrated using DIOPTAS; manual background subtraction was done in Fityk.Bright-field imaging (BF-TEM) was performed using an FEI Titan Themis 60-300 transmission electron microscope operated at an 80 kV accelerating […]
