Correlation between clinical diagnostics and necropsical findings

open access: yesArchivo Médico de Camagüey, 2020
Background: the indices of discrepancy and coincidence of the causes of death between the clinical and morphological diagnosis constitute, indirectly, an indicator of the quality of medical care. Objective: to determine the relationship between clinical

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Ultrafast Energy Transfer Induced Lasing From a Coplanar Donor‐Acceptor‐Donor Molecule in a Microspherical Cavity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

Hole Transfer Dynamics in Thin Films of Mixed‐Dimensional Quasi‐2D Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Charge transfer dynamics in quasi‐2D perovskite (PEA2MAn−1PbnI3n+1), grown with a distinct dimensionality gradient are investigated. Selective excitation of the n = 4 phase reveals efficient hole transfer to n = 2 and n = 3 within tens of picoseconds, while n = 1 acts as a hole‐blocking layer. These findings highlight the importance of minimizing n = 1
