Business Strategy and the Environment, EarlyView.ABSTRACT For regenerative agricultural systems such as food forests to move from experimental niches to scalable market solutions, they must attract consumer acceptance and sufficient willingness to pay a price premium. This study examines the demand‐side drivers of consumers' willingness to pay for food forest produce, focusing on nature connectedness,

Ideas y Valores, 1991 Este texto que permanecía inédito hasta ahora y cuyo manuscrito custodia la Biblioteca Nacional de Colombia, fue redactado por Restrepo durante una de las sesiones del Congreso constituyente de 1830. Se trata indudablemente de una de sus intervenciones en aquel congreso.

Chemistry – A European Journal, EarlyView.We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...

Breaking the Mold: Electrophilic Hydrophosphanation Emerges
Chemistry – A European Journal, EarlyView.Electrophilic hydride attack on the olefin, instead of the classical nucleophilic addition by a phosphanido ligand, is unveiled in rhodium‐catalyzed olefin hydrophosphanation. This hydride‐driven pathway operates for both activated and inactivated olefins, with transition states characterized by elongated Rh─H bonds and nascent C─H bond formation ...

Decoding Heptazine Architectures: From Molecular Association to Structural Insight
Chemistry – A European Journal, EarlyView.A comprehensive study (NMR and theoretical) of three novel heptazine derivatives that self‐assemble into dimers has been conducted, highlighting their versatility as a platform for multifunctional supramolecular and optoelectronic materials. ABSTRACT Heptazine (Hpz) derivatives display remarkable supramolecular organization governed by noncovalent ...

Assessment of Attainable Distances in Proteins by Through‐Space 19F–19F Couplings
Chemistry – A European Journal, EarlyView.De novo synthesized difluorinated tryptophan analogues are site‐specifically incorporated into Cyclophilin A (CypA). 19F–19F NOESY build‐up experiments are recorded for each labeled protein, and the distances derived from cross‐relaxation rates are compared to reference distances.

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of
