Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized

Continuously wavelength-tunable high harmonic generation via soliton dynamics

, 2017
We report generation of high harmonics in a gas-jet pumped by pulses self-compressed in a He-filled hollow-core photonic crystal fiber through the soliton effect. The gas-jet is placed directly at the fiber output.

Gourd‐Inspired Design of Unit Cell with Multiple Gradients for Physiological‐Range Pressure Sensing

Advanced Functional Materials, EarlyView.
Gourd‐shaped micro‐dome arrays with coordinated modulus, conductivity, and geometric gradients co‐optimize sensitivity and linearity in piezoresistive tactile sensors. Under pressure, a solid upper dome embeds into a porous lower dome, triggering rapid contact‐area growth and series‐to‐parallel conduction, enabling unsaturated, intensity‐resolved ...

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

Advanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...
