Ultrafast Micrometric Laser Structuring of Polymer Surfaces for Highly Organized Skeletal Muscle Tissue Modeling

ABSTRACT Engineered surface topographies have proven to be an efficient method to replicate in vitro the architecture of highly organized tissues by controlling the spatial arrangement of cells. In this work, we studied the ability to guide muscle cell development using femtoseco...

The Contribution of DAS to the Routine Monitoring of Seismicity in Oceanic Islands: The Case for Faial (Azores)

Distributed acoustic sensing (DAS) deployed on submarine telecom cables is bound to revolutionize the earthquake monitoring routine currently performed by seismic network operators, particularly in domains where most seismic activity originates offshore. In this work, we analyze...

Bismuth Nanogratings With Narrow Plasmon Resonances for Dynamic Polarized Color Generation and Colorimetric Sensing

ABSTRACT Bismuth nanostructures are appealing for sustainable color generation and sunlight harvesting, thanks to their non‐toxicity and their tunable visible‐to‐near‐infrared interband plasmon resonances. However, owing to their broad and polarization‐insensitive spectral featur...

Guest-host approach to reduce driving voltages in electro optic liquid crystal devices

We describe a simple guest-host approach allowing the reduction of driving voltages in liquid crystal (LC) electro optic devices via the increase of the effective dielectric anisotropy. This is achieved by doping the nematic LC host by molecules possessing high dipole moments. Po...

Probing relaxed myosin states in hypertrophic cardiomyopathy by second harmonic-generation microscopy

This study explores the use of polarized second-harmonic generation (pSHG) to investigate myosin conformation in the relaxed state, differentiating between the actin-available, disordered (ON) state and the energy-conserving, ordered (OFF) state. By shifting the ON/OFF equilibriu...
