Direct Ink Writing of Conductive Hydrogels

open access: yesAdvanced 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

open access: yesMathematical 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 ...

The invariance of classical electromagnetism under Charge-conjugation, Parity and Time-reversal (CPT) transformations

open access: yes, 1990
The invariance of classical electromagnetism under CPT is studied by considering the motion of a charged particle in electric and magnetic fields. Applying CPT transformations to various physical quantities and noting that the motion still behaves ...

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

open access: yesAdvanced 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.

Thick branes in Born–Infeld determinantal gravity in Weitzenböck spacetime

open access: yesEuropean 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.
