Fair weather induced charges and currents on tall wind turbines and experiments with kites [PDF]

open access: yes, 2016
Earth’s atmospheric potential rapidly increases up to few tens of kilovolts below 200 m altitude. This potential drop will induce charge to tall objects at ground by virtue of electrostatic induction.

In‐Operando 4D‐STEM and STEM‐EBIC Imaging of Electric Fields and Charge Carrier Behavior in Biased Silicon p–n Junctions

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a study of how 4D‐STEM centre of mass measurements and STEM‐EBIC can be used to map the positions, directions, and strengths of electric fields in semiconductor devices. The contrast mechanisms of both techniques are tested and compared with simulations to build a robust analysis of an in situ device in the electron microscope ...

Diurnal characteristics of lightning flashes detected over the São Paulo lightning mapping array [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2015
AbstractThis study examines diurnal variations of lightning flash characteristics observed by the Lightning Mapping Array in São Paulo, Brazil. The diurnal flash counts exhibit the typical afternoon convective maximum. The mean source altitude demonstrates a discrete increase that is temporally coincident with the local sunrise. The mean horizontal and

Atomic Scale Ordering of Liquid Water at a Dynamic Pt(111) Interface Under Electrochemical Conditions Imaged by Electron Holography

open access: yesAdvanced Energy Materials, EarlyView.
High resolution electron holography was used to image the projected electric potential of ordered water layers at the interface to a platinum (111) electrode. The observed reorganization of the water layers upon applying external potentials suggests that the electric potential drop of the electric double layer is mainly carried by the polarization ...

Preliminary Research on a Comparison and Evaluation of FY-4A LMI and ADTD Data through a Moving Amplification Matching Algorithm

open access: yesRemote Sensing, 2020
In this study, a new moving amplification matching algorithm was proposed, and then the temporal and spatial differences and correlation were analysed and evaluated by comparing the FengYun-4A Lightning Mapping Imager (FY-4A LMI) data and the China ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.
