Electric Field Effect in Atomically Thin Carbon Films [PDF]

open access: yesScience, 2004
We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions, metallic, and of remarkably high quality.

Development and Research of a Medium Vertical Dipole Electromagnetic Pulse Simulator

open access: yesEnergies, 2023
In this paper, the design of a self-developed EMP simulator with a 5 m height and an inverted conducting mono-cone antenna with a cone half-angle of 32° is introduced. The experimental region of the simulator is a circular area of 25 m in diameter around

The Statistical Characteristics Analysis for Overvoltage of Elevated Transmission Line under High-Altitude Electromagnetic Pulse Based on Rosenblatt Transformation and Polynomial Chaos Expansion

open access: yesEnergies, 2023
A High-Altitude Electromagnetic Pulse (HEMP) could induce very fast transient overvoltage (VFTO) with nanosecond level rise time and mega-volt amplitude, which severely threatens the electrical devices connected to the elevated transmission line.

A stochastic contour path finite‐difference time‐domain method for uncertainty analysis of metal slot size

open access: yesIET Microwaves, Antennas & Propagation, 2023
A stochastic contour path finite‐difference time‐domain (S‐CP‐FDTD) algorithm is presented for electromagnetic wave propagation in metallic enclosures with uncertain slot size. The correlation coefficient between the field and size of slot was set to one.

Physicochemical characterization and genotoxicity of the broad class of carbon nanotubes and nanofibers used or produced in U.S. facilities

open access: yesParticle and Fibre Toxicology, 2020
Background Carbon nanotubes and nanofibers (CNT/F) have known toxicity but simultaneous comparative studies of the broad material class, especially those with a larger diameter, with computational analyses linking toxicity to their fundamental material ...

Analyticity and the Unruh effect: a study of local modular flow [PDF]

open access: yesJournal of High Energy Physics
The Unruh effect can be formulated as the statement that the Minkowski vacuum in a Rindler wedge has a boost as its modular flow. In recent years, other examples of states with geometrically local modular flow have played important roles in understanding

Rigid elliptical cross-section ogive-nose projectiles penetration into concrete targets

open access: yesDefence Technology, 2021
The elliptical cross-section ogive-nose projectile (ECOP) has recently attracted attention because it is well suited to the flattened shape of earth-penetrating weapons.
