High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Fabrication and Characterization of PEDOT:PSS‐Based Microstructured Electrodes for In Vitro Cell Culture

Advanced Materials Interfaces, EarlyView.
Poly(3,4‐ethylenedioxythiophene) poly(styrene sulfonate) (PEDOT:PSS)‐based microstructured electrodes are fabricated using vacuum soft lithography as an alternative to conventional methods. This novel fabrication approach enables the production of scalable and cost‐effective bioelectronic devices.

La aleatoriedad en la educación: el orden de los factores si altera el producto

, 2021
Argentina, poseedora de un sólido sistema de educación superior a través de universidades nacionales públicas, mayormente con ofertas presenciales, se encuentra transitando un proceso de aislamiento social preventivo en el ámbito educativo desde mediados de marzo de 2020. Al pensar en el acceso a la educación y al tránsito de los alumnos durante

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

Advanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

The Structure of Nitro‐ and Polynitropyrazoles: X‐Ray Crystallography Versus Theoretical Calculations

Asian Journal of Organic Chemistry, EarlyView.
Abstract This publication presents the geometries of 157 nitro‐ and polynitropyrazoles. Among these, 109 compounds were theoretically studied using mainly the B3LYP/6–311++G(d,p) level of theory. Three‐parameter Lee‐Yang‐Parr (B3LYP) is a density functional theory (DFT) method widely used in computational chemistry and constitutes an acceptable ...

Shedding Light on the Precatalytic Mixture of Pd(OAc)2 and Cooperating Bipyridone Ligands for the C─H Functionalization of Arenes

ChemCatChem, EarlyView.
The reactions of the common palladium precursors Pd(OAc)2 and PdCl2 and cooperating bipyridone ligands leads to well defined complexes which are general precatalysts for the direct C─H arylation of arenes, more active than Pd(OAc)2/ligand mixtures in nonpolar solvents.
