Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 204-223, June 2026.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

TD3 Deep Reinforcement Learning Control Approach for a DC‐DC Multiport Converter Used in Low‐Power EV Applications

open access: yesIET Smart Energy Systems, Volume 2, Issue 2, Page 158-169, June 2026.
A TD3‐based deep reinforcement learning controller is developed for a multiport converter in low‐power EV applications. The data‐driven, model‐free strategy improves dynamic performance under constant power load destabilisations and demonstrates advanced intelligent control suited for next‐generation smart and integrated energy systems.

Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

open access: yesAdvanced Functional Materials, Volume 36, Issue 34, 27 April 2026.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

A Systematic Review of End‐of‐Life Motorcycles: Identifying Challenges, Trends, and Gaps

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 3, March 2026.
Existing studies on End‐of‐Life Motorcycles (ELMs) are systematically reviewed to identify methodological approaches, research trends, and regional gaps. The literature shows a strong concentration of studies in Asian countries and a predominance of quantitative and technical methods focused on environmental impacts and logistics.

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

open access: yesEuropean Policy Analysis, Volume 12, Issue 2, Spring 2026.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
