Blade Count and Rotational Speed Sensitivity of Vertical‐Axis Turbines Under Guided Vehicle‐Generated Transient Wakes

open access: yesEnergy Science &Engineering, EarlyView.
Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Mono‐dimensional, two‐dimensional and Doppler echocardiographic measurements in healthy Standardbred neonatal foals in the first 5 days of life

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Bodyweight, age and breed influence the echocardiographic assessment of foals. There are no echocardiographic studies in Standardbred neonatal foals. Objectives To describe echocardiographic values for selected variables, evaluate intra‐ and inter‐observer variability and assess cardiac changes in the first 5 days of life in healthy

Recent Progress on Graphitic Carbon Nitride–Based Photocatalysts for Hydrogen Peroxide Synthesis

open access: yesExploration, EarlyView.
This review summarizes recent progress in using graphitic carbon nitride (g‐C3N4) photocatalysts to produce hydrogen peroxide (H2O2). It highlights how solar energy can cleanly convert water and oxygen into this valuable chemical. We discuss key modification strategies, such as defect engineering, doping, and junction construction, to enhance ...

Acceleration of Singlet Oxygen Evolution by Sonopiezoelectric Charge Transfer Over SrTiO3‐TiO2 Heterojunction for Selective Oxidation

open access: yesExploration, EarlyView.
A sonopiezo‐triggered singlet oxygen evolution system by S‐scheme SrTiO3‐TiO2 heterojunction was rationally designed to selectively remove electron‐rich pollutants from water. ABSTRACT Sonopiezo‐mediated heterogeneous catalysis is a promising technology for efficient removal of organic pollutants from wastewater. Nevertheless, it is challenging in real

Fast Calculation for the Flow and Heat Transfer of Tempered Fractional Maxwell Viscoelastic Fluid

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study develops a tempered fractional Maxwell model to simulate unsteady thermal flow in viscoelastic fluids, capturing key rheological behaviors. A fast SOE‐based algorithm is proposed to improve the computational efficiency of the numerical scheme. Results reveal how key parameters influence fluid motion and heat transfer, demonstrating the model'

What Are We Learning About the Research‐Practice Gap From HRD Scholars and HRD Scholar‐Practitioners?

open access: yesHuman Resource Development Quarterly, EarlyView.
ABSTRACT The research‐practice gap (the gap) in HRD remains a significant challenge, hindering the application of academic research to practice and the integration of workplace challenges into research efforts. It is critical for HRD research to address the gap to develop evidence‐based solutions for learning and organizational performance. The purpose
