Organic-Inorganic Layered and Hollow Tin Bromide Perovskite with Tunable Broadband Emission.

ACS Applied Materials and Interfaces, 2018
Recently, layered perovskites attracted great attention for its excellent stability and light-emitting property. However, most of them rely on the toxic element lead and their emission quantum yields are generally low.

Iodide, bromide, and ammonium in hydraulic fracturing and oil and gas wastewaters: environmental implications.

Environmental Science and Technology, 2015
The expansion of unconventional shale gas and hydraulic fracturing has increased the volume of the oil and gas wastewater (OGW) generated in the U.S. Here we demonstrate that OGW from Marcellus and Fayetteville hydraulic fracturing flowback fluids and ...

Granular Activated Carbon Treatment May Result in Higher Predicted Genotoxicity in the Presence of Bromide.

Environmental Science and Technology, 2016
Certain unregulated disinfection byproducts (DBPs) are more of a health concern than regulated DBPs. Brominated species are typically more cytotoxic and genotoxic than their chlorinated analogs.

Methylammonium Lead Bromide Perovskite-Based Solar Cells by Vapor-Assisted Deposition

, 2015
The past two years have seen the uniquely rapid emergence of a new class of solar cell based on organic–inorganic halide perovskite. Although less explored than its tri-iodide counterparts, CH3NH3PbBr3 has a larger bandgap of 2.3 eV with a higher voltage
