All‐Optical Logic Gates and Programmable Photonic Organo‐Polymer Devices

Advanced Electronic Materials, EarlyView.
Four PDMS‐based photonic devices imitating the shapes of Y‐structure, hexagonal mesh, dual in‐phase quadrature, and cascaded MZI array are demonstrated and shown to function as all‐optical OR gates. Furthermore, a PDMS hexagonal mesh, containing dye‐doped regions, is shown to enable performance as a programmable photonic device, where its ...

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low‐resource settings: a prospective quality improvement study

BJS (British Journal of Surgery), EarlyView., 2020
Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

Advanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

Structural Tuning of Self‐Conductive Polymer as Gas Diffusion Layer for Electrocatalytic Reactions at High Current

Advanced Energy Materials, EarlyView.
A self‐conductive, all‐polymer, hydrophobic gas diffusion layer is prepared by electropolymerizing a porous poly(3,4‐ethylenedioxythiophene) (PEDOT) layer onto a porous polytetrafluorethylene substrate. The gas and charge transport properties are effectively tuned by the identity of the ionic dopant in the PEDOT layer, which ultimately enables stable ...

Advances in Thermoelectric Thin Films Grown by Atomic Layer Deposition: A Critical Review of Performance and Challenges

Advanced Energy Materials, EarlyView.
This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning
