Iron oxide modified diamond blends containing different amounts of ultradispersed diamond were prepared and characterized by nitrogen physisorption, X-ray diffraction, temperature programmed reduction, Mössbauer and IR spectroscopy. The catalytic behavior of these composite materials in methanol decomposition to hydrogen,...

Inflammation of the choroid plexus and ependymal layer of the ventricle following intraventricular hemorrhage.

Translational stroke research

Simard PF, Tosun C, Melnichenko L, Ivanova S, Gerzanich V, Simard JM.
PMID: 21731590
Transl Stroke Res. 2011 Jun;2(2):227-31. doi: 10.1007/s12975-011-0070-8.

Intraventricular hemorrhage (IVH), which afflicts thousands of people of all ages every year, frequently results in the development of communicating hydrocephalus. Classically, IVH-induced hydrocephalus has been attributed to reduced resorption of cerebrospinal fluid (CSF) due to dysfunction of arachnoid...

Inelastic neutron scattering experiments have been performed on the archetype compound YbB(12), using neutron polarization analysis to separate the magnetic signal from the phonon background. With decreasing temperature, components characteristic for a single-site spin-fluctuation dynamics are suppressed, giving place...
