Experimentally observed defect tolerance in the electronic structure of lead bromide perovskites [PDF]
arXiv, 2023 Point defect tolerance in materials, which extends operational lifetime, is essential for societal sustainability, and the creation of a framework to design such properties is a grand challenge in the material sciences. Using three prototypical lead bromide perovskites in single crystal form and high-resolution synchrotron-based X-ray spectroscopy, we ...

Exciton-relaxation dynamics in lead halides [PDF]
J. Lumin. 102-103, 663 (2003), 2002 We survey recent comprehensive studies of exciton relaxation in the crystals of lead halides. The luminescence and electron-spin-resonance studies have revealed that excitons in lead bromide spontaneously dissociate and both electrons and holes get self-trapped individually. Similar relaxation has been also clarified in lead chloride. The electron-hole

Atmospheric residence time of CH3Br estimated from the junge spatial variability relation [PDF]
, 1998 The atmospheric residence time for methyl bromide (CH3Br) has been estimated as 0.8 +/- 0.1 years from its empirical spatial variability relative to C2H6, C2Cl4, CHCl3, and CH3Cl.

Benzylethyldimethylammonium bromide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 The crystal structure of the title compound, C(11)H(18)N(+)·Br(-), has been determined as part of an ongoing study of the influence of the alkyl chain length on amphiphilic activity of quaternary ammonium salts. The title salt forms a three-dimensional network of ionic contacts through weak C-H⋯Br hydrogen bonds, with donor-acceptor distances in the ...
