Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity
Advanced Functional Materials, EarlyView.This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Light‐Actuated Fiber‐Climbing Inchworm Robot Toward Endoluminal Navigation
Advanced 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

Photometry of active Centaurs: Colors of dormant active Centaur nuclei [PDF]
, 2019 We present multiband photometric observations of nine Centaurs. Five of the targets are known active Centaurs (167P/CINEOS, 174P/Echeclus, P/2008 CL94, P/2011 S1, and C/2012 Q1), and the other four are inactive Centaurs belonging to the redder of the two
