Semiconducting Pt Structures Stabilized on 2D MoS2 Crystals Enable Ultrafast Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
The interaction of small Pt particles with 2D MoS2 crystals can stabilize bilayer Pt structures, with a semiconducting electronic structure. The semiconducting electronic structure of Pt bilayers constitutes the so far unexplored transition domain between the bulk‐like, metallic band structure of compact nanoparticles and the discrete atomic orbitals ...

Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

open access: yesAdvanced Materials, EarlyView.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.
