Direct Ink Writing of Conductive Hydrogels
Advanced Functional Materials, EarlyView.This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

High frequency electrical oscillations in cavities
Mathematical Modelling and Analysis, 2018 If the interior of a conducting cavity (such as a capacitor or a coaxial cable) is supplied with a very high-frequency electric signal, the information between the walls propagates with an appreciable delay, due to the finiteness of the speed of light ...

Thick branes in Born–Infeld determinantal gravity in Weitzenböck spacetime
European Physical Journal C: Particles and Fields, 2022 By adopting the idea of Born–Infeld electromagnetism, the Born–Infeld determinantal gravity in Weitzenböck spacetime provides a way to smooth the Big Bang singularity at the classical level.

Relativistic Causality and Conservation of Energy in Classical Electromagnetic Theory [PDF]
, 2002 The change of the electromagnetic field in a particular place due to the event of a change in the motion of a charged particle can occur only after the light signal from the event can reach this place. Naive calculations of the electromagnetic energy and the work performed by the electromagnetic fields might lead to paradoxes of apparent non ...

On Electromagnetic Turbulence [PDF]
arXiv, 2022 Combining a generalized current in the set of Maxwell's equations offers a useful framework to address the complex phenomena of electromagnetic turbulence. The fluidic-electromagnetic analogy implies that diffraction is the analog phenomenon of EM turbulence and indicates norms to design suitable plasmon circuity to control electromagnetic turbulence ...

Motion of charged particles in an electromagnetic knot [PDF]
J.Phys.A43:235401,2010, 2010 In this paper we consider the classical relativistic motion of charged particles in a knotted electromagnetic field. After reviewing how to construct electromagnetic knots from maps between the three-sphere and the two-sphere, we introduce a mean quadratic radius of the energy density distribution in order to study some properties of this field.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices
Advanced Functional Materials, EarlyView.An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.
