Linear assembly of patchy and non-patchy nanoparticles.

Linear assemblies of nanoparticles show promising applications due to their collective electronic, optical and magnetic properties. Rational design and controllable organization of nanoparticles in one-dimensional structures can strongly benefit from the marked similarity between conventional step-growth polymerization reactions and directional step-wise assembly of nanoparticles in linear chai...

Punctate keratopathy of West Indians.

Clinical Features (Fig. 1, overleaf) The condition appears to be asymptomatic and presents as a chance clinical finding. The corneal lesions are round, discrete dense opacities 0 5 mm. or less in diameter. They lie at the level of Bowman's membrane and usually extend just into the superficial stroma.
