We report the synthesis of monodisperse Pt nanocrystals with three different shapes-cubes, cuboctahedra, and octahedra, selectively, with similar sizes of 9-10 nm by a modified polyol process. We found that addition of silver ion enhances the crystal growth rate along 100, and essentially determines the shape and surface structure of the Pt nanocrystals.(More)
As was known by the ancient Greeks, there are five platonic solids that can be constructed by selecting a regular convex polygon and having the same number of them meet at each corner: tetrahedron, octahedron, hexahedron (cube), icosa-hedron, dodecahedron. [1] The beauty in their symmetry and their apparent simplicity continue to inspire generations of(More)
A fundamental step in the construction of nanowire devices is transfer of the nanowires from their stock to the substrate on top of which the device will be built. Therefore, alignment and controlled positioning of the nanowires are highly desirable, especially for the large-scale (e.g., on a 4-inch (10-cm) wafer) fabrication of parallel device arrays.(More)
We have developed a general method for assembling colloidal particles into one-dimensional lines of single particle thickness. Well-spaced, parallel single particle lines can be readily deposited on a substrate from a dilute Langmuir-Blodgett particle monolayer via a stick-slip motion of the water-substrate contact line. The particle density within the(More)
Adult onset leukodystrophy with neuroaxonal spheroids is an uncommon cause of dementia. Both hereditary (autosomal dominant) and sporadic cases have been described. A 41-year-old African woman presented with inappropriate behavior and personality change consistent with frontal lobe dysfunction. MRI demonstrated diffuse frontoparietal white matter signal(More)
UNICEF and the International Children's Palliative Care Network undertook a joint analysis in three sub-Saharan countries-Zimbabwe, South Africa, and Kenya-to estimate the palliative care need among their children and to explore these countries' capacities to deliver children's palliative care (CPC). This report concerns the findings from South Africa. The(More)

Death and dying are not easy to deal with. Perhaps you or someone you love is facing an illness that cannot be cured. Few of us are really ready for the hard choices that may have to be made at the end of life. It can be hard for everyone involved—the dying person, their family and loved ones, and health care providers, too. But there is a way to ease pain(More)
