Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

Advanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Técnicas utilizadas para detecção e quantificação de aflatoxina M1 no Leite

Boletim de Indústria Animal, 2012
Aflatoxina é a denominação dada a um grupo de substâncias tóxicas, produzidas principalmente por dois fungos Aspergillus flavus e Aspergillus parasiticus, que se desenvolvem sobre muitos produtos agrícolas e alimentos quando as condições de umidade do produto, umidade relativa do ar e temperatura ambiente são favoráveis.

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 ...

The Role of Coordination Mechanisms and Transaction Costs Promoting Sustainability Performance in Agri‐Food Supply Chains: Evidence From Ecuador

Agribusiness, EarlyView.
ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

Distanzabhängiger Energietransfer zwischen organischen Fluorophoren und einwandigen Kohlenstoffnanoröhren

Angewandte Chemie, EarlyView.
Wir zeigen, dass hybridisierte dsDNA eine senkrechte Ausrichtung zu SWCNTs einnimmt, und präsentieren eine abstandsabhängige Übertragung der Energie von Fluoreszenzfarbstoffen auf SWCNTs. Der Energietransfer von Kohlenstoffnanoröhren (CNET) folgt einer d−5‐Abhängigkeit mit einem charakteristischen Abstand von 7,4 nm (± 0,7 nm) für 50 % Energietransfer.

Distance‐Dependent Energy Transfer Between Organic Fluorophores and Single‐Walled Carbon Nanotubes

Angewandte Chemie International Edition, EarlyView.
We demonstrate that the dsDNA part adopts a perpendicular orientation to the SWCNT and present a distance‐dependent energy transfer of single fluorescent dyes to SWCNTs. Carbon nanotube energy transfer (CNET) obeys a d−5 distance dependence with a characteristic distance of 7.4 nm (± 0.7 nm) for 50 % energy transfer.
