Biodegradable Inverse Opals with Controlled Discoloration
Advanced Materials Interfaces - Tập 5 Số 10 - 2018
Ji‐Won Kim, Joon‐Seok Lee, Shin‐Hyun Kim
AbstractColloidal crystals and their derivatives possess photonic bandgap property, being useful in various applications, including structural coloration and colorimetric sensing. In this work, inverse opals made of a biodegradable polymer, poly(lactic‐co‐glycolic acid) (PLGA), are prepared to provide a controlled discoloration. To make PLGA inverse opals, a monolayer of silica particles is first ... hiện toàn bộ

Vastly Enhanced BiVO4 Photocatalytic OER Performance by NiCoO2 as Cocatalyst
Advanced Materials Interfaces - Tập 4 Số 19 - 2017
Thangavelu Palaniselvam, Le Shi, Gangaiah Mettela, Dalaver H. Anjum, Renyuan Li, Krishna P. Katuri, Pascal E. Saikaly, Peng Wang
AbstractHere, a simple and efficient preparation of NiCoO2 nanoparticle modified nanoporous bismuth vanadate (BiVO4) thin film and its application in photoelectrocatalytic (PEC) oxygen evolution reaction (OER) is demonstrated. The role of NiCoO2 in the composite electrode (BiVO4/NiCoO2) is twofold: OER cocatalyst and band structure modifier. It improves surface reaction kinetics for PEC OER and en... hiện toàn bộ
Interaction of Water with Atomic Layer Deposited Titanium Dioxide on p‐Si Photocathode: Modeling of Photoelectrochemical Interfaces in Ultrahigh Vacuum with Cryo‐Photoelectron Spectroscopy
Advanced Materials Interfaces - Tập 8 Số 11 - 2021
Thorsten Cottre, Mathias Fingerle, Melanie Kranz, Thomas Mayer, Bernhard Kaiser, Wolfram Jaegermann
AbstractThis study combines cryo‐photoelectron spectroscopy and electrochemical analysis techniques to investigate the p‐Si/SiO2/TiO2/H2O system in the context of water‐splitting. Atomic layer deposition is used for the preparation of a TiO2 thin film coating for a p‐Si/SiO2 photocathode. First, an interface experiment is performed to study the contact properties of the interface between p‐Si/SiO2... hiện toàn bộ
Enhanced H2 Generation of Au‐Loaded, Nitrogen‐Doped TiO2 Hierarchical Nanostructures under Visible Light
Advanced Materials Interfaces - Tập 1 Số 1 - 2014
Brundabana Naik, Sun Mi Kim, Chan Ho Jung, Song Yi Moon, Sang Hoon Kim, Jeong Young Park
Hierarchical N‐doped TiO2 nanostructured catalysts with micro‐, meso‐, and macroporosity are synthesized by a facile self‐formation route using ammonia and titanium isopropoxide precursor. UV–vis diffuse reflectance spectra confirm the red shift and band gap narrowing due to the doping of N species in the TiO2 nanoporous catalyst. Hierarchical macroporosity with fibrous channel patterning is obser... hiện toàn bộ
Bioinspired Gas‐Confined Hollow Microfiber with 2D Conducting Polymer/Graphene Skeleton for Ultrasensitive Liquid Environment Sensor
Advanced Materials Interfaces - Tập 8 Số 24 - 2021
Xuejing Zou, Qianqian Jiang, Xusheng Wang, Yonglin He, Yuqiao Chai, Hui Ma, Xinlei Ma, Yapei Wang, Mianqi Xue
AbstractDue to the strong liquid intermolecular force, feasible sensing‐detection methods in liquid environments are absent. Inspired by fish swim bladder, herein, a hollow‐structured microfiber is designed to realize high‐performance sensing in liquid environments. It composes of 2D polypyrrole (2DPPy) and reduced graphene oxide (rGO), and its wall has a porous skeleton of 2DPPy/rGO/2DPPy (2DPrG2... hiện toàn bộ
MXene‐Based Composites: Synthesis and Applications in Rechargeable Batteries and Supercapacitors
Advanced Materials Interfaces - Tập 6 Số 8 - 2019
Jian Yang, Weizhai Bao, Pauline Jaumaux, Songtao Zhang, Chengyin Wang, Guoxiu Wang
AbstractThe family of 2D transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) is rapidly studied since the initial synthesis of Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has hydrophilic groups (F, OH, and O), which leads the surface to be negatively charged. Consequently, the negatively charged surface can facilitate the compounding of MX... hiện toàn bộ
Silver Iodide Induced Resistive Switching in CsPbI3 Perovskite‐Based Memory Device
Advanced Materials Interfaces - Tập 6 Số 7 - 2019
Shuping Ge, Yunxia Huang, Xiaojuan Chen, Xinran Zhang, Zhongcheng Xiang, Ruoxuan Zhang, Wenping Li, Yimin Cui
AbstractLead halide perovskites‐based memory devices have attracted considerable interest due to their unique current–voltage (I–V) hysteresis. Herein, all‐inorganic CsPbI3 perovskite film surviving 30 d of air storage is prepared by using a poly‐vinylpyrrolidone‐assisted passivation method under fully open‐air condition. Afterwards, a memory device with a sandwich structure of Ag/CsPbI3/indium ti... hiện toàn bộ
An Evolving Insight into the Progress of Material Design for Membrane‐Based Electrochemical Lithium Ion Detection
Advanced Materials Interfaces - Tập 8 Số 19 - 2021
Atousa Bakhtiarvand Bakhtiari, Bahareh Mohammadi, Parisa Moazzam, Dorsa Didehroshan, Amir Razmjou
AbstractThe global shift of energy resources from fossil fuel to renewable energy sources has already begun. The critical energy element of lithium (Li) plays an important role in this energy transition, which is demonstrated by the fast increase in its demand. Rapid and continuous detection of Li has become an important field, as the overexploitation of Li sites, mainly brines, could compromise t... hiện toàn bộ
Hierarchically Organized Ultrathin NiO Nanofibers/Highly Defective‐rGO Heteronanocomposite: An Advanced Electrode Material for Asymmetric Supercapacitors
Advanced Materials Interfaces - Tập 6 Số 20 - 2019
Mahesh Kumar Paliwal, Sumanta Kumar Meher
AbstractHerein, defective‐rGO (D‐rGO) is endorsed as a unique conducting matrix for defect‐induced interfacial growth of ultrathin dangling‐NiO nanofibers. The physicochemical analyses corroborate added defect density on the graphene surface, defect‐induced growth of NiO, and excellent hydrophilicity of NiO/D‐rGO heteronanocomposite. Thorough electrochemical analyses of NiO/D‐rGO heteronanocomposi... hiện toàn bộ
