Electric Discharge in Erupting Mud

open access: yesGeophysical Research Letters, 2022
Self‐ignition during the explosive eruption of mud volcanoes can create flames that in some cases reach heights that exceed hundreds of meters. To study the controls on electrical discharge in natural mud, we performed laboratory experiments using a ...

Template synthesis of copper azide primary explosive through Cu2O@HKUST-1 core-shell composite prepared by “bottle around ship” method

open access: yesDefence Technology, 2023
Copper azide (CA), as a primary explosive with high energy density, has not been practically used so far because of its high electrostatic sensitivity.

Behavioral study of selected microorganisms in an aqueous electrohydrodynamic liquid bridge

open access: yesBiochemistry and Biophysics Reports, 2017
An aqueous electrohydrodynamic (EHD) floating liquid bridge is a unique environment for studying the influence of protonic currents (mA cm−2) in strong DC electric fields (kV cm−1) on the behavior of microorganisms. It forms in between two beakers filled

Phases of holographic interfaces

open access: yesJournal of High Energy Physics, 2021
We compute the phase diagram of the simplest holographic bottom-up model of conformal interfaces. The model consists of a thin domain wall between three-dimensional Anti-de Sitter (AdS) vacua, anchored on a boundary circle.

Fabrication of Slanted Cu Nanopillars with Uniform Arrays

open access: yesNanomaterials and Nanotechnology, 2016
Slanted Cu nanopillars with uniform arrays were fabricat‐ ed using slanted Si channel structures as templates. A slanted plasma etching technique was employed, utilizing a Faraday cage system for the formation of these slanted channel structures.

First Records of Heartbeats via ECG in a Stingless Bee, Melipona flavolineata (Apidae, Meliponini), during Contention Stress Using Isoflurane as an Anesthetic

open access: yesInsects, 2023
The hemodynamic activity of Melipona flavolineata workers was evaluated during restraint stress for a period of 30 min. The observed parameters were power variation in the elapsed time, and subsequently, six periods of one second were divided and called ...

KALwEN: A New Practical and Interoperable Key Management Scheme for Body Sensor Networks [PDF]

open access: yes, 2008
Key management is the pillar of a security architecture. Body sensor networks(BSNs) pose several challenges -- some inherited from wireless sensor networks(WSNs), some unique to themselves -- that require a new key management scheme to be tailor-made ...

Electric Fields Enhance Ice Formation from Water Vapor by Decreasing the Nucleation Energy Barrier

open access: yesColloids and Interfaces, 2022
Video images of ice formation from moist air under temperature and electric potential gradients reveal that ambient electricity enhances ice production rates while changing the habit of ice particles formed under low supersaturation.

Reconfigurable antennas radiations using plasma Faraday cage [PDF]

open access: yes2015 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2015
This letter presents a new reconfigurable plasma antenna associated with a Faraday cage. The Faraday cage is realized using a fluorescent lamp. A patch antenna with a broadside radiation pattern or a monopole antenna with an end-fire radiation pattern , operating at 2.45 GHz, is placed inside Faraday cage.

Homogenized boundary conditions and resonance effects in Faraday cages [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016
We present a mathematical study of two-dimensional electrostatic and electromagnetic shielding by a cage of conducting wires (the so-called ‘Faraday cage effect’). Taking the limit as the number of wires in the cage tends to infinity, we use the asymptotic method of multiple scales to derive continuum models for the shielding, involving homogenized ...
