Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Effect of metal loading and Ce addition on biochar-supported Co catalysts for CO2 methanation

Biochar
CO2 hydrogenation to methane is an interesting topic that can result in CO2 mitigation, providing a solution for global warming. Using a sustainable catalyst in that process will be considered as a plus point that makes the whole system (material ...

Investigation of the kinetics of methanation of a post-coelectrolysis mixture on a Ni/CZP oxide catalyst

Journal of CO2 Utilization
The use of synthetic natural gas (SNG) as a plug-and-play fuel coming from renewables can help to overcome the limitations given by the intermittency of renewable energy. A way to implement the production of SNG pass through the co-electrolysis of CO2 to

Modelling and Simulation of Methanation Catalytic Reactor for Renewable Electricity Storage

Chemical Engineering Transactions, 2013
Storing renewable electricity in a natural gas grid is an innovative concept. Renewable energy (wind or solar power) is stored as chemical energy in existing storage capacities, which is an advantage over hydrogen.

Ni/YMnO3 perovskite catalyst for CO2 methanation

, 2021
This work proposes an innovative Ni catalyst supported over YMnO3 perovskite as a promising catalytic system for CO2 methanation reaction. Under reductive conditions, the attendance of Mn redox couples within the layered perovskite structure promotes the

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
