Attractive Ni…O Interactions Enable Non‐Alternating Ethylene‐Carbon Monoxide Copolymerization

Angewandte Chemie, EarlyView.
Attractive Ni···O interactions are established in phosphine‐imidated and phosphine‐phenolate nickel catalysts, enabling non‐alternating ethylene‐carbon monoxide copolymerization, resulting in superior CO tolerance, productivity and stability compared to the state‐of‐the‐art benchmark.

Assessing Household Welfare in Response to Rising Food Prices in The Gambia

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines how rising food prices affected household welfare in The Gambia using nationally representative data from the 2015/16 Integrated Household Survey (IHS‐3). The analysis reflects household consumption behavior and market conditions prevailing during that period and provides a structural benchmark for understanding ...

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

Angewandte Chemie, EarlyView.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Quantifying Consumer Tradeoffs Across Firm‐Level Strategic Positioning Dimensions: Evidence from US Craft Beer Consumers

Agribusiness, EarlyView.
ABSTRACT Strategic positioning becomes increasingly important as markets mature, particularly in consumer‐facing industries that offer similar products, experiential cues, and values‐based messages. This study offers a conceptual model to examine the strategic positioning factors that motivate consumers to visit one local business over another before ...

Unlocking Zn‐Ion Diffusion in Disordered Rocksalt Cathodes for Nonaqueous Zn‐Ion Batteries

Angewandte Chemie, EarlyView.
Developing viable cathode materials for multivalent battery chemistries is challenging due to the intrinsic sluggish diffusion kinetics. A disordered rocksalt oxide host was found to “lock” the cycling of zinc ions from nonaqueous electrolyte. We unlock zinc ion diffusion in the disordered rocksalt by introduction of a percolating vacancy network ...

FIRE‐GNN: Force‐Informed, Relaxed Equivariance Graph Neural Network for Rapid and Accurate Prediction of Surface Properties

Advanced Intelligent Discovery, EarlyView.
This study introduces FIRE‐GNN, a force‐informed, relaxed equivariant graph neural network for predicting surface work functions and cleavage energies from slab structures. By incorporating surface‐normal symmetry breaking and machine learning interatomic potential‐derived force information, the approach achieves state‐of‐the‐art accuracy and enables ...

An Enantioselective Alkene Aminoarylation to Form Chiral Indolines via Electrostatically‐Directed Palladium Catalysis

Angewandte Chemie, EarlyView.
Enantioselective aminoarylation of ortho‐allyl anilines is achieved under mild conditions. Key to success is the electrostatically‐directed nature of the key aminopalladation step, achieved by using the sulfonated chiral ligand sSPhos on palladium. A detailed study of electronic trends allows tuning of the sulfonamide protecting group to enable good ...

Multiple solutions for an elliptic system with indefinite Robin boundary conditions

Advances in Nonlinear Analysis, 2017
Multiplicity of solutions is proved for an elliptic system with an indefinite Robin boundary condition under an assumption that links the linearisation at 0 and the eigenvalues of the associated linear scalar operator.
