Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

Surface Plasmon Raman Scattering Studies of Liquid Crystal Anchoring on Liquid-Crystal-Based Self-Assembled Monolayers

open access: yes, 2016
We studied the anchoring of 6CB on a series of self-assembled monolayers (SAMs) with a functional group that mimics that of the nematic liquid crystal (LC).

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.

Visual computation of surface lightness: Local contrast vs. frames of reference

open access: yes, 2010
Seeing black, white and gray surfaces, called lightness perception, might seem simple because white surfaces reflect 90% of the light they receive while black surfaces reflect only 3%, and the human retina is composed of light sensitive cells.

SURFACE AZIMUTHAL ANCHORING ENERGY BETWEEN THE GRATING SURFACE AND NEMATIC LIQUID CRYSTAL LAYER STUDIED BY USING A GEOMETRIC MODEL

open access: yes, 2017
A simple geometric model is proposed for estimating the azimuthal anchoring energy between the sinusoidal relief grating surface and nematic liquid crystal layer of a liquid crystal display (LCD) device as a function of the grating height and grating ...

Fracture-based grasping: dynamic impact enables predictable robotic anchoring to freshwater ice

open access: yesnpj Robotics
Gripping to smooth and wavy substrates, such as naturally occurring ice, presents a challenge for climbing robots in the field. Existing ice anchoring solutions require either substantial initial surface compression force (drilling; at least 50 Newtons ...

Light‐Actuated Fiber‐Climbing Inchworm Robot Toward Endoluminal Navigation

open access: yesAdvanced Functional Materials, EarlyView.
A kirigami‐inspired soft inchworm robot harnesses optical energy from a customized side‐emitting optical fiber, guaranteeing its propulsion along the fiber body. The wavelength‐selective responsiveness of dye‐functionalized liquid crystal elastomers and the application of temporal illumination patterns enable sequential control of robot components. The

Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.
