Melt-extruded light-responsive amphibious liquid crystal elastomer fibers with reprogrammable actuation modes

Fabien Sorin

Untethered liquid crystal elastomer (LCE) fiber actuators are promising candidates for soft actuators due to their analogies to biological muscles. However, most LCE fiber actuators are difficult to (re)program and primarily only work in air, which signifi ...

Superior Adhesion of Monolayer Amorphous Carbon to Copper

Oleg Yazyev, Ruslan Yamaletdinov, Hanning Zhang

The single‐atom thickness of graphene holds great potential for device scaling, but its effectiveness as a thin metal‐ion diffusion barrier in microelectronics and a corrosion barrier for plasmonic devices is compromised by weak van der Waals interactions ...

Spontaneous Raman scattering as a probe of vibrational quantum coherence and plasmonic near-field

Valeria Vento

Spontaneous vibrational Raman scattering is a ubiquitous form of light-matter interaction whose description necessitates quantization of the electromagnetic field. It is usually considered an incoherent process since it stems from the fluctuations of the v ...

Airborne metal nanoparticles released by azides detonation: determination and potential public exposure

Christian Ludwig, Andrea Testino, Tianyu Cen, Laura Torrent Fabrega

Metal azides are highly energetic materials that release a large amount of gas upon detonation. They also release metal particles, generating an aerosol. The most common azide is sodium azide (NaN3), which is used nowadays in car airbags. If the decomposit ...

Cross-calibration and first vertical ECE measurement of electron energy distribution in the TCV tokamak

Ambrogio Fasoli, Stefano Coda, Joan Decker, Arsène Stéphane Tema Biwole

This paper describes the first vertical electron cyclotron emission measurement of non-thermal electron distributions in the Tokamak à Configuration Variable. These measurements were conducted in runaway electron scenarios and in the presence of electron c ...

Bianisotropic metasurface enables a nonlinear pseudo-diode: asymmetric second-harmonic generation

Olivier Martin, Karim Achouri, Andrei Kiselev, Sergejs Boroviks

Bianisotropic metasurfaces empower planarized optical components with subwavelength thicknesses that are not amenable to conventional optics. In particular, bianisotropy gives control over the spatial dispersion and allows engineering of both spectral and ...

Accurate Prediction of Hall Mobilities in Two-Dimensional Materials through Gauge-Covariant Quadrupolar Contributions

Nicola Marzari

Despite considerable efforts, accurate computations of electron-phonon and carrier transport properties of low-dimensional materials from first principles have remained elusive. By building on recent advances in the description of long-range electrostatics ...
