Investigations on the Effects of Trip Wires on the Performances of a Rectangular Wing

open access: yes, 2016
This work investigates the effects of small cylindrical elements (“trip wires”) on the aerodynamic performances of a rectangular wing at Reynolds numbers between 5 × 104 and 2 × 105. The diameter and position of the perturbing cylinders are changed in order to evaluate modifications in drag and lift coefficients in comparison to the unperturbed wing ...

Food Tastes in the United States: Convergence or Divergence?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Assessing the Impact of Promotions on Consumer Purchasing Behavior During Crises

open access: yesAgribusiness, 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 ...

Effect of forward moment on recovery motion against tripping

open access: yesPLOS ONE
Investigating the fall recovery motion mechanism is crucial to prevent fall injuries. Among the various parameters of motion and posture, the forward moment can be considered the representative parameter of the magnitude of tripping from a kinematic perspective.

Hierarchically engineered electrocatalysts for durable oxygen reduction in zinc–air batteries

open access: yesAIChE Journal, EarlyView.
Abstract Rechargeable zinc–air batteries (ZABs) are promising energy storage systems but are limited by sluggish oxygen reduction reaction (ORR) kinetics at the air cathode. Herein, we report hierarchically engineered cobalt tetraaminophthalocyanine/MXene (CoPc/MXene) electrocatalysts prepared via cetyltrimethylammonium bromide‐mediated self‐assembly ...

Coupled Fe3O4‐Cluster Precipitates and Single Fe‐Atom Catalysts Can Boost Oxygen Reduction via Concomitantly Accelerated Water Dissociation

open access: yesAngewandte Chemie, EarlyView.
Fe3O4 clusters can be precipitated onto Fe–N–C SACs through a residual‐oxygen‐assisted precipitation approach. Compelling evidence, including operando spectroscopy and ab initio calculations, suggests that Fe3O4‐cluster precipitates not only induce asymmetric electronic structures of Fe‐N4 active center to optimize the OH* adsorption, but also ...

Talk to Your Data: An Agentic Artificial Intelligence‐Driven Decision‐Support Framework for Prosumer Energy Optimization and Recommendations

open access: yesAdvanced Intelligent Systems, EarlyView.
An agentic AI‐driven decision‐support framework for prosumers is proposed, integrating PV generation, load profiling, and multihorizon optimization within a four‐agent architecture. The approach significantly reduces grid dependence, enhances self‐sufficiency and prevents system oversizing.

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

open access: yesAngewandte 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 ...

Effect of metastable retained austenite on dynamic mechanical properties of nanostructured bainitic steel under high-strain rate deformation

open access: yesJournal of Materials Research and Technology
In this study, modifying the austenitizing temperature offers a strategically viable way towards creating blocky retained austenite (BRA) with varying sizes and morphologies in nanostructured bainitic steel, in strikingly contrast to the conventional ...
