Here, we report a remarkable 15 Å nanolayered tin phosphate, Sn(HPO4)2·3H2O (SnP-H+ or SnP), and its clay-like gel, which are multifunctional and are prepared using earth-abundant Sn and P chemicals by a facile, environmentally benign and potentially cost-effective process. This new energy material is discovered here as the best proton conductor among all the known layered phosphates with a ver...

The design, fabrication, and properties of one of a new class of gradient-index lenses are reported. The lens is an f/2.25 GRIN singlet based on a nanolayered polymer composite material, designed to correct for spherical aberration. The light gathering and focusing properties of the polymer lens are compared to a homogeneous BK7 glass singlet with a similar f-number. The modulation transfer fun...

A new class of hierarchically structured polymer optical materials possessing an internal refractive index gradient that mimics biological optical materials is described. The new materials permit the fabrication of gradient refractive index (GRIN) lenses with an unprecedented variety of index gradients. Gradients with different functional forms in both the radial and axial directions have been ...
