Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

open access: yesAdvanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

General Synthesis of Amorphous Pd‐Based Nanoparticles Towards Highly Efficient Nitrate‐to‐Ammonia Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A family of amorphous palladium‐based multi‐component phosphides nanoparticles, synthesized via a robust one‐step wet‐chemical method, overcoming the immiscibility of different elements and the difficulty in forming a stable, disordered structure. When applied in the electrochemical nitrate reduction reaction, these nanocatalysts effectively suppress ...

IDEAL-Cell, a High Temperature Innovative Dual mEmbrAne Fuel-Cell

open access: yes, 2009
IDEAL-Cell is a new concept of a high temperature fuel cell operating in the range 600-700°C. It is based on the junction between the anode part of a PCFC and the cathode part of a SOFC through a mixed H+ and O2- conducting porous ceramic membrane.

Electrolyte‐Induced Cu+ Preservation Results in a Selectivity Switch of Electrocatalytic CO2 Reduction at a Copper‐Organic Framework as Electrocatalyst

open access: yesAdvanced Functional Materials, EarlyView.
The active role of KCl as a neutral electrolyte enables switching the selectivity on a Cu organic framework from C1 to C2+ products during electrocatalytic CO2 reduction. ABSTRACT We introduce a copper‐nicotinate (Cu‐NA) framework as a halogenide‐stabilized Cu+/Cu0 pre‐catalyst for electrocatalytic CO2 reduction with high C2+ selectivity in a “neutral”

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
