Energy Science &Engineering, Volume 14, Issue 1, Page 61-79, January 2026.Cyclopentane shows great potential as a working fluid for recovering gas turbine exhaust heat in organic rankine cycle (ORC) systems. A dynamic characteristics and control strategies analysis of a flooded ORC system using cyclopentane reveals that system safety can be ensured by adjusting the working fluid pump speed based on evaporator liquid‐level ...

Comparison of Mixing Performance Based on Phase Difference in Modified New AM Impeller
International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.Helical ribbon impellers are commonly used for mixing high‐viscosity fluids, but they are expensive to manufacture. To address this, the authors developed the Advanced Mixing (AM) impeller, which demonstrated higher mixing efficiency compared to other high‐viscosity impellers.

Resistance due to vortex motion in the $\nu=1$ bilayer quantum Hall superfluid
, 2005 The longitudinal and Hall resistances have recently been measured for quantum Hall bilayers at total filling $\nu=1$ in the superfluid state with interlayer pairing, both for currents flowing parallel to one another and for "counterflowing" currents in ...

PAMM, Volume 25, Issue 4, December 2025.ABSTRACT Hydrogen is a promising carbon‐free fuel but faces challenges due to combustion instability and nitrogen oxide (NOx${\rm NO}_x$) emissions during combustion. This study investigates the potential of blending hydrocarbons (methane, propane) or ammonia with hydrogen‐air flames in order to minimize these challenges.
