Engineered Biographical Defects in Two-Dimensional Nonanediaminium Lead Iodide Perovskites: From Synthesis to Reversible Photodegradation

Abstract The choice of lead precursor (PbO versus PbI2), the Pb:diamine stoichiometric ratio, and the crystallization regime influence the defect landscape and optical stability of the layered hybrid perovskite (NonDA)PbI4. Diffuse reflectance spectroscopy, X-ray photoelectron sp...

Density Structure of the Lithosphere in upper Priamurye

Abstract A 3D density model for the lithosphere of Upper Priamurye, which extends to a depth of 130 km, was constructed based on the anomalous gravity field. The lithospheric mantle displays a banded structure defined by a series of alternating relatively low and high density zon...

Age of Zircons from Sedimentary Rocks of the Elgon Formation of the Ulban Terrane on the Coast of the Ulban Bay

U–Pb dating of detrital zircons from sandstones of the Elgon Formation showed that the formation is no older than Oxfordian in age (early Late Jurassic) and not Middle Jurassic as previously assumed based on the rare flora and fauna finds and the position of the formation within...

Impact of Earthquake Migration on the Structure and Dynamics of Diffuse Seismicity in Some Sections of the Tan-Lu Fault System

Abstract The impact of earthquake migration on the dynamics and structure of minor seismicity in the areas adjacent to the Tan-Lu fault system in Russia was investigated based on the analysis of temporal variation of M ≥ 2.5 earthquake occurrences in Priamurye at different time i...
