Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition

Small, EarlyView.
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

Cosserat curve model for superelasticity of helices [PDF]

Nanotechnology, 2009
Superelasticity behavior of helices has been the focus of recent research in micro-/nano-engineering, while the traditional Kirchhoff rod model restricts itself in the bending and torsion conditions. With the aid of the concept of a Cosserat curve, a novel theoretical basis has been established for statics and dynamics of helices with essential ...
