Size-Dependent Lattice Structure and Confinement Properties in CsPbI₃ Perovskite Nanocrystals: Negative Surface Energy for Stabilization [PDF]

, 2020
CsPbI₃ nanocrystals with narrow size distributions were prepared to study the size-dependent properties. The nanocrystals adopt the perovskite (over the nonperovskite orthorhombic) structure with improved stability over thin-film materials.

Engineering of Double Absorber Organic‐Perovskite Solar Cells for >34% Efficiency with V2O5 as Back Surface Field Layer

Advanced Photonics Research, EarlyView.
This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.

TPT sulfonate, a single, oral dose schistosomicidal prodrug: In vivo efficacy, disposition and metabolic profiling

International Journal for Parasitology: Drugs and Drug Resistance, 2018
Treatment of schistosomiasis relies precariously on just one drug, praziquantel (PZQ). In the search for alternatives, 15 S-[2-(alkylamino)alkane] thiosulfuric acids were obtained from a previous research program and profiled in mice for efficacy against

Strongly correlated wave functions for artificial atoms and molecules

, 2002
A method for constructing semianalytical strongly correlated wave functions for single and molecular quantum dots is presented. It employs a two-step approach of symmetry breaking at the Hartree-Fock level and of subsequent restoration of total spin and ...
