One-dimensional disordered photonic structures with two or more materials

, 2018
Here we would like to discuss the light transmission modulation by periodic and disordered one dimensional (1D) photonic structures. In particular, we will present some theoretical and experimental findings highlighting the peculiar optical properties of:

Synthesis of bulk, dense, nanocrystalline yttrium aluminum garnet from amorphous powders [PDF]

, 2007
Amorphous powders of Al2O3x2014;37.5 mol% Y2O3 (yttrium aluminum garnet (YAG)) were prepared by coprecipitation, decomposed at 800xB0;C, and hot-pressed uniaxally at low temperature (600xB0;C) and a moderate pressure (750 MPa). Optimum conditions yielded

Interface Stability and Kinetics of Sulfide Electrolytes in all‐Solid‐State Batteries

Angewandte Chemie International Edition, EarlyView.
We reveal the chemical and electrochemical stability among cathode types and functional materials in contact with sulfide‐based electrolytes, the role of cathode charged states in interfacial reactions, and the corresponding volume changes at the interface.

Ytterbium doped nano-crystalline optical fiber for reduced photodarkening

, 2010
We report suppression of photodarkening in Yb-doped nano-crystalline fibers in silica host. The photodarkening induced loss reduced by 20 times compared to Yb-doped aluminosilicate fibers. The laser efficiency of the nano-crystalline fiber was 79%

Rare Earths and the Balance Problem: How to Deal with Changing Markets? [PDF]

, 2018
The balance between the market demand and the natural abundance of the rare-earth elements (REEs) in ores, often referred to as the Balance Problem (or the Balancing Problem), is a major issue for REE suppliers.
