Effect of flame temperature on structure and CO oxidation properties of Pt/CeO2 catalyst by flame-assisted spray pyrolysis

Applications in Energy and Combustion Science
Flame synthesis offers the potential for the synthesis of structure-controlled catalysts. In this study, Pt/CeO2 nanoparticles were synthesized via flame-assisted spray pyrolysis (FASP) and used as CO oxidation catalysts.

Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

Advanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

Improving Ionic Conformality Across Polymer Electrolyte|Electrode Interfaces

Advanced Materials, EarlyView.
Polymer electrolytes typically form physically intimate electrode interfaces but often fail to maintain continuous ionic pathways, critically limiting battery performance. Through strategic compositional design, this study introduces a molecular ionic composite electrolyte that effectively reduces interfacial ionic depletion, ensuring consistent ion ...

Multicomponent Fuel Diffusion Flames: Flame Structure for Coupled Diffusion-Flame and Premixed-Flame Burning Regimes

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
The analysis addresses some aspects of the extinction and the structure of diusion flames established by burning of two fuels. This analysis is asymptotically performed presuming one-global-step chemical reactions with large activation energies. By working with fuels with dierent activation energies, the structure is composed by two zones with dierent ...
