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 ...

Journal of Advanced Concrete Technology, 2017 A method for estimating the rebar force crossing a crack under model I loading in RC beams using the crack mouth opening displacement (CMOD) is proposed based on fracture mechanics accounting for bond slip at rebar-concrete interface. In the method, a CMOD is regarded as a consequence of the combined action of applied loads, rebar bridging forces and ...

Advanced Functional Materials, EarlyView.Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for
