A Flexible Poling‐Free Piezoelectric Energy Harvester Based on Gradient Ti‐Doped BiFeO3 Films

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A self‐aligned polarization is realized in compositional gradient Ti‐doped BiFeO3 films via the formation of defect dipoles and strain gradient. The self‐poling behavior is robust to resist high electric field and elevated temperature. The fabricated poling‐free piezoelectric energy harvester delivers output comparable to the poled ones.

An ANN-Based Approach for Prediction of Sufficient Seismic Gap between Adjacent Buildings Prone to Earthquake-Induced Pounding

Applied Sciences, 2020
Earthquake-induced structural pounding may cause major damages to structures, and therefore it should be prevented. This study is focused on using an artificial neural network (ANN) method to determine the sufficient seismic gap in order to avoid ...

Soil Carbon Markets in the Making: Power Relations and Matters of Concern in Offsetting and Insetting

Environmental Policy and Governance, EarlyView.
ABSTRACT This paper investigates emerging soil carbon markets and seeks to identify the groups of actors and power relations that constitute their structure and function. Voluntary soil carbon markets (VSCMs) are emerging globally as a key mechanism for generating carbon removals as part of climate mitigation efforts.

Cross‐Entropy of Power Spectral Density Function: A Modal Identification Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The power spectral density (PSD) function of measured structural response contains a significant amount of information, including the modal parameters (natural frequencies, damping ratios). Output‐only system identification or modal identification technique can be used for extracting such modal parameters from the measured response or its ...

Non-Linear Analysis of Inter-Story Pounding between Wood-Framed Buildings during Ground Motion

Geosciences, 2019
Pounding between adjacent buildings during ground motion may result in structural damage or lead to total destruction of structures. The research on the phenomenon has recently been much advanced; however, the analyses have been carried out only for ...

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Linking of adjacent three-storey buildings for mitigation of structural pounding during earthquakes

Bulletin of Earthquake Engineering, 2016
The reports after major earthquakes indicate that the earthquake-induced pounding between insufficiently separated buildings may lead to significant damage or even total collapse of structures.

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

A New Formula of Impact Stiffness in Linear Viscoelastic Model for Pounding Simulation

Shock and Vibration, 2016
The phenomenon of earthquake-induced structural pounding was extensively studied by some researchers using different models for the impact force. The aim of this paper is to provide a new formula of impact stiffness in the linear viscoelastic contact ...
