Scalable sub-cycle pulse generation by soliton self-compression in hollow capillary fibers with a decreasing pressure gradient

Journal of the European Optical Society-Rapid Publications, 2023
Advances in the generation of the shortest optical laser pulses down to the sub-cycle regime promise to break new ground in ultrafast science. In this work, we theoretically demonstrate the potential scaling capabilities of soliton self-compression in ...

Ultrafast magnetic field induced by anisotropy in carbon nanotubes irradiated by intense laser fields [PDF]

EPJ Web of Conferences
We report an unexpected result of the anisotropy of the nonlinear optical response of carbon nanotubes, inherent to their chirality. Using a model based on the resolution of the semiconductor Bloch equations, we theoretically demonstrate that, upon ...

Influence of the acceptor roughness on the aspect ratio of silver paste lines printed by laser-induced forward transfer

Results in Physics, 2016
Silver paste voxels and lines are printed by laser-induced forward transfer onto three different substrates. Increasing the roughness of the acceptor substrates enhances the aspect ratio of the lines printed.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
