High-pressure crystallography [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 2007
Since the late 1950's, high-pressure structural studies have become increasingly frequent, following the inception of opposed-anvil cells, development of efficient diffractometric equipment (brighter radiation sources both in laboratories and in synchrotron facilities, highly efficient area detectors) and procedures (for crystal mounting, centring ...

Normal Pressure Hydrocephalus — High Pressure Normocephalus [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1980
The case history to be presented spans most of the lifetime of a young lady who is now twenty-two years old, and it reflects the stages of development of our knowledge of several important neurosurgical concepts.

Some Magnetic Properties and Magnetocaloric Effects in the High-Temperature Antiferromagnet YbCoC₂

Magnetochemistry, 2023
The YbCoC2 compound, which crystallizes in a base-centered orthorhombic unit cell in the Amm2 space group CeNiC2 structure, is unique among Yb-based compounds due to the highest magnetic ordering temperature of TN=27 K.

Nanocrystalline iron at high pressure [PDF]

, 2001
X-ray diffraction measurements were performed on nanocrystalline iron up to 46 GPa. For nanocrystalline epsilon-Fe, analysis of lattice parameter data provides a bulk modulus, K, of 179±8 GPa and a pressure derivative of the bulk modulus, K[prime], of 3 ...
