Charging and Electric Field Effects on Hydrogen Molecules Physisorbed on Graphene

Klaus Kern, Shai Mangel, Alessio Scavuzzo, Tobias Wollandt

Molecular hydrogen adsorbed on graphene was investigated by analyzing rotational excitation spectra obtained with a gate-tunable scanning tunneling microscope (STM). Through the shift of the rotational excitation energy, the tunability of physisorbed H2 on ...

A review of the modeling approaches of the lightning M-component with special attention to their current and electric field characteristics

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Carlo Alberto Nucci, Qi Li

In this paper, we present the characteristics of current, electric fields and modeling approaches of lightning M-component mode of charge transfer. We consider both the classical M-components (occurring after return strokes) and M-component-type ICC (Initi ...

Size dependence of second-harmonic scattering from nanoparticles: Disentangling surface and electrostatic contributions

Sylvie Roke, Arianna Marchioro, Bingxin Chu

Polarimetric angle-resolved second-harmonic scattering (AR-SHS) is an all-optical tool enabling the study of unlabeled interfaces of nano-sized particles in an aqueous solution. As the second harmonic signal is modulated by interference between nonlinear c ...

On the durability of surgical masks after simulated handling and wear

Jian Wang, Véronique Michaud, Vincent Marc Varanges, Baris Çaglar, Yann Albert Gérard Lebaupin, René M. Rossi

After the spread of COVID-19, surgical masks became highly recommended to the public. They tend to be handled and used multiple times, which may impact their performance. To evaluate this risk, surgical masks of Type IIR were submitted to four simulated tr ...

Ionization Waves Enhance the Production of X-rays during Streamer Collisions

Marcos Rubinstein

Experimental data show that in laboratory sparks, X-rays are produced in time synchronization with the meeting of streamers of opposite polarity just before the final breakdown of the discharge gap. It has been suggested that the electric field enhancement ...

Hydraulically amplified dielectric actuator taxels

Herbert Shea, Min Gao, Edouard Franck Vincent Gustave Leroy

A dielectric actuator including an enclosure forming a cavity having a dielectric fluid therein, the enclosure having a base, a flexible membrane and a reversibly-stretchable membrane, and a pair of electrodes, one electrode of the pair of electrodes arran ...

Quantitative Mapping of the Charge Density in a Monolayer of MoS2 at Atomic Resolution by Off-Axis Electron Holography

Andras Kis, Dumitru Dumcenco, Dmitry Ovchinnikov

The electric potential, electric field, and charge density of a monolayer of MoS2 have been quantitatively measured at atomic-scale resolution. This has been performed by off-axis electron holography using a double aberration-corrected transmission electro ...

Electric-field control of single-molecule tautomerization

Klaus Kern, Christian Alexander Stephan Dette, Shai Mangel, Katharina Polyudov, Tobias Wollandt

The electric field is an important parameter to vary in a single-molecule experiment, because it can directly affect the charge distribution around the molecule. Yet, performing such an experiment with a well-defined electric field for a model chemical rea ...

Effect of input voltage frequency on the distribution of electrical stresses on the cell surface based on single-cell dielectrophoresis analysis

Philippe Renaud, Hanie Kavand

Electroporation is defined as cell membrane permeabilization under the application of electric fields. The mechanism of hydrophilic pore formation is not yet well understood. When cells are exposed to electric fields, electrical stresses act on their surfa ...
