Correlative Chemical Imaging to Reveal the Nature of Different Commercial Graphene Materials

Small Methods, EarlyView.
Commercial graphene‐based materials from different sources and of varying complexities were investigated correlatively using commonly employed imaging techniques, including SEM, AFM, ToF‐SIMS, AES, and EDS. ToF‐SIMS combined with SEM was identified as the most effective combination for simultaneously resolving the complex morphology and chemical ...

Lightning discharge identification system [PDF]

, 1981
A system for differentiating between cloud to cloud and cloud to ground lightning discharges is described which includes an electric field antenna that senses the rate of charge of an electric field produced by a lightning discharge.

Quantifying the Influence of Lightning Strike Pressure Loading on Composite Specimen Damage

Applied Composite Materials, 2019
Experimental work has shown that a component of lightning strike damage is caused by a mechanical loading. As the profile of the pressure loading is unknown a number of authors propose different pressure loads, varying in form, application area and ...

Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

High Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

Polyaniline-based all-polymeric adhesive layer: An effective lightning strike protection technology for high residual mechanical strength of CFRPs

Composites Science And Technology, 2019
Carbon fiber reinforced plastics (CFRPs) are vulnerable to lightning strikes due to their low electrical conductivity and low heat resistance. A lightning strike can damage CFRP structure catastrophically.

Experimental analysis of the strands breaking characteristics of optical fibre composite overhead ground wire due to simulating lightning strike

, 2020
With the increasing application of OPGW (optical fibre composite overhead ground wire) in power systems, the strands in OPGW are frequently broken due to lightning strikes.

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

Lightning Often Strikes Twice [PDF]

, 2005
Contrary to popular misconception, lightning often strikes the same place twice. Certain conditions are just ripe for a bolt of electricity to come zapping down; and a lightning strike is powerful enough to do a lot of damage wherever it hits.
