Iron Energy Carrier: Experimental Characterisation, Combustion Diagnostic and Benchmarking with Other Clean Metal Fuels

open access: yesEnergy Science &Engineering, EarlyView.
This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

Maxwell–Lorentz Electrodynamics Revisited via the Lagrangian Formalism and Feynman Proper Time Paradigm

open access: yesMathematics, 2015
We review new electrodynamics models of interacting charged point particles and related fundamental physical aspects, motivated by the classical A.M. Ampère magnetic and H. Lorentz force laws electromagnetic field expressions. Based on the Feynman proper

Supercritical Angle Fluorescence and Raman Techniques in Biophotonics

open access: yesLaser &Photonics Reviews, EarlyView.
Supercritical angle fluorescence (SAF) microscopy and supercritical angle Raman (SAR) spectroscopy have emerged as powerful tools in the field of biophotonics, enabling high‐resolution imaging and spectroscopy of biological specimens near interfaces. This review article provides a comprehensive overview of the principles, techniques, applications, and ...

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Electromagnetism as an emergent phenomenon: a step-by-step guide

open access: yesNew Journal of Physics, 2014
We give a detailed description of electrodynamics as an emergent theory from condensed-matter-like structures, not only per se but also as a warm-up for the study of the much more complex case of gravity.

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

open access: yesLaser &Photonics Reviews, EarlyView.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Special solutions of coupled classical harmonic oscillators with the addition of magnetic monopoles

open access: yesPhysics Open
In this paper, we undertake a thorough investigation into the existence of magnetic monopoles, elusive particles theorized to possess isolated north or south magnetic poles. These hypothetical entities have long captured the imagination of physicists and

The Particle as a Statistical Ensemble of Events in Stueckelberg–Horwitz–Piron Electrodynamics

open access: yesEntropy, 2017
In classical Maxwell electrodynamics, charged particles following deterministic trajectories are described by currents that induce fields, mediating interactions with other particles. Statistical methods are used when needed to treat complex particle and/

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

open access: yesHigh Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.
