Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

Advanced Intelligent Systems, EarlyView.
The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.

Theoretical Model of Distributed Parameters for Eccentric Coaxial Line and Its Application in Oil Wells

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aiming at the current demand for using wellbore coaxial lines with tubing and casing in oil wells, implementing microwave chemical‐assisted crude oil upgrading underground, and promoting “carbon‐zero” mining projects in oil field development, we carried out theoretical analysis, simulations, and applied research on the distributed parameters ...

Characterization and Modeling of Industrial Phosphoric Acids' Rheological Behavior: Impact of Magnesium Monoxide on Viscosity

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.

Quantum Carnot Bound from Petz Recovery Maps

Advanced Physics Research, EarlyView.
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.
