Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Enzyme‐Loaded Fe3+‐Modified Polydopamine Microparticles: Bioreactor Systems for Operating Biocatalytic Cascades, Enantioselective Transformations and Sensor Applications

Advanced Functional Materials, EarlyView.
Enzyme‐loaded Fe3+‐modified polydopamine microparticles (Fe3+‐PD) act as hybrid biocatalytic frameworks demonstrating NADH peroxidase‐mimic catalytic activities, operation of biocatalytic cascades in confined media, and enantioselective oxidation of D/L‐DOPA. ABSTRACT We report on the synthesis of Fe3+‐modified porous polydopamine microparticles acting

Reducing Environmental Impact on SME Metals Production Process Using Life Cycle Assessment and Analytical Hierarchy Process Method

Jurnal Ilmiah Teknik Industri, 2020
The ABC metal SME produces some wastes, such as liquid waste, solid waste, and smoke. The problem is hazardous waste dumped directly into the environment without any waste treatments which had bad impact on the environment around its SME. Therefore, this

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, EarlyView.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.
