摘要:
Some embodiments disclosed herein include a ceramic body including a first region and a second region. The first region may include a host material and first concentration of a dopant that is effective to produce luminescence. The second region may include the host material and second concentration of the dopant. In some embodiments, the first region has an average grain size that is larger than an average grain of the second region. The ceramic body may, in some embodiments, exhibit superior internal quantum efficiency (IQE). Some embodiments disclosed herein include methods for the making and using the ceramic bodies disclosed herein. Also, some embodiments disclosed herein lighting apparatuses including the ceramic bodies disclosed herein.
摘要:
Described herein are heterogeneous materials comprising a p-type semiconductor comprising two metal oxide compounds of the same metal in two different oxidation states and an n-type semiconductor having a deeper valence band than the p-type semiconductor valence bands wherein the semiconductor types are in ionic communication with each other. The heterogeneous materials enhance photocatalytic activity.
摘要:
High-throughput methods are provided for quantitatively measuring the modulation of heat shock protein (HSP) expression in a cell by exposing the cell to at least one stress and measuring cellular stress responses. High-throughput methods for identifying modulators (activators or inhibitors) of HSP or HSF expression in a cell by treating the cell with an agent, such as a compound or composition, exposing the cell to a stress, and measuring responses of the cell to the stress in the presence or absence of the agent are also provided. Devices useful in performing high-throughput methods of the invention, and modulators identified using such methods, are also provided.
