A brief history of Maxwell's equations

, 2019
Maxwell's equations explain all phenomena of classical electrodynamics, magnetism, and optics the way Newton's equaMaxwelltions of motion describe classical mechanics. Maxwell introduced the theoretical description of electromagnetic waves and fostered a

Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood

Advanced Science, EarlyView.
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

A Mathematical Modeling of Time-Fractional Maxwell’s Equations Under the Caputo Definition of a Magnetothermoelastic Half-Space Based on the Green–Lindsy Thermoelastic Theorem

Mathematics
This study has established and resolved a new mathematical model of a homogeneous, generalized, magnetothermoelastic half-space with a thermally loaded bounding surface, subjected to ramp-type heating and supported by a solid foundation where these types

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Generalized formulations of Maxwell's equations for numerical Vlasov-Maxwell simulations

, 2006
When solving numerically approximations of the Vlasov-Maxwell equations, the source terms in Maxwell's equations coming from the numerical solution of the Vlasov equation do generally not satisfy the continuity equation which is necessary for Maxwell's ...

Maxwell's Equations for Nanotechnology

, 2012
Classical physics, which includes Maxwell's equations, a hundred years ago couldn’t explain stability of atoms, the periodic table of elements, the chemical bond, the discrete excitation energies of atoms and their energetic state, the ionization of atoms, the spectra, including its fine structure and transition rules, experimental evidence (X-ray ...

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

Advanced Science, EarlyView.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.
