Angewandte Chemie, EarlyView.An iron‐catalyzed protocol for the cascade cyclization of N‐aryl and N‐benzoyl acrylamides promoted by methane and other gaseous alkanes is reported. The current protocol provides an efficient platform for the conversion of feedstock gaseous alkanes into complex and medicinally relevant N‐heterocycles.

Peptide Electrostatic Modulation Directs Human Neural Cell Fate
Advanced Science, EarlyView.This study explores the effect of charge on the bioactivity of peptide‐based supramolecular materials. The design of a peptide library with varying charges that self‐assemble into supramolecular fibers is presented, demonstrating how the surface charge of these fibers, used as artificial extracellular matrices, influences the fate of human neural ...

Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents
Advanced Science, EarlyView.In this study, chemically designed nanoscale‐distance‐tuned based on silica‐coated iron oxide nanoparticles are used to investigate how dipolar interactions affect magnetic resonance imaging (MRI) contrast. By varying shell thickness, researchers modulated dipolar interactions and observed an exponential increase in transverse relaxivity (r2) that ...

Assessing the Impact of Promotions on Consumer Purchasing Behavior During Crises
Agribusiness, EarlyView.ABSTRACT Understanding how households modify their food expenditure decisions during times of crisis is essential because consumer purchasing behavior frequently changes during these times. This study looks at these behavioral shifts during the COVID‐19 pandemic, concentrating on how price sensitivity and response to sales promotions changed over the ...

American Journal of Botany, EarlyView.Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.
