Spin excitations near the pressure-induced antiferromagnetic transition in SrCu₂(BO₃)₂. [PDF]

J Appl Crystallogr
Inelastic neutron scattering on SrCu2(BO3)2 at 4.2 GPa reveals dispersive spin excitations in the antiferromagnetic phase, consistent with linear‐spin‐wave theory and highlighting the key role of interlayer coupling.SrCu2(BO3)2 is a frustrated quantum magnet which realizes the Shastry–Sutherland model. The system exhibits a sequence of pressure‐induced

Digital twin quantifies spatial‐heterogeneity‐driven failure in fast‐charging lithium‐ion battery anodes

InfoMat, EarlyView.
This work constructs a series of graphite anodes with systematically varied binder distribution, porosity, and electrode thickness to resolve the role of microstructural heterogeneity during fast charging. The digital twin framework reveals how phase‐level structural gradients govern Li plating, SEI formation, and diffusion‐induced stresses, providing ...

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Software-Defined Elastic Optical Network Node Supporting Spectrum Defragmentation

, 2017
The elastic optical network (EON) benefits from improved spectrum utilization, but also faces new challenges in resource allocation. The spectrum continuity and contiguity constraints in routing and spectrum allocation can cause spectrum fragmentation ...

When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference

Psychology &Marketing, EarlyView.
ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

PLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...
