Machine‐Learning‐Guided Discovery of Boron‐Free Narrowband Blue Thermally Activated Delayed Fluorescence Emitters

open access: yesAngewandte Chemie, EarlyView.
A data‐driven discovery engine—exhaustive enumeration of carbazole‐containing polycyclic aromatic hydrocarbons (Cz‐PAHs) followed by machine learning—identifies boron‐free, narrowband blue thermally activated delayed fluorescence emitters for organic light‐emitting diodes (OLEDs).

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

Indium Clusters With 6s2 Lone‐Pair Effect as Excitonic Electron Reservoirs for Direct 2e− Photocatalytic H2O2 Photosynthesis

open access: yesAngewandte Chemie, EarlyView.
This study demonstrates that indium clusters with 6s2 lone‐pair effect anchored on carbon nitride act as excitonic electron reservoirs to boost charge separation and O2 activation for highly selective direct 2e− oxygen reduction. This work establishes cluster‐mediated electron reservoir engineering as a general strategy for enhancing selective ...

Implantation‐On‐Chip: An AI‐Based Platform for Monitoring the Embryo Trophoblast–Endometrial Stroma Cross Talk With Xenobiotics Interference

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...

Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

open access: yesAngewandte Chemie, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...

Vieses raciais e sub-representação genômica no contexto dos escores de risco poligênico em embriões: implicações para a discriminação genética na reprodução assistida e a proteção de pessoas vulneráveis

open access: yesCadernos Ibero-Americanos de Direito Sanitário
Objetivo: compreender como a relação entre a sub-representação genômica de populações vulneráveis na reprodução assistida e os vieses raciais implica em dinâmicas que podem estar relacionadas à discriminação genética e a exacerbação das desigualdades ...
