Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction

Advanced Functional Materials, EarlyView.
This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Performance analysis of zeotropic organic Rankine cycle with a vapor-liquid injector

Case Studies in Thermal Engineering
To improve the performance of small-scale organic Rankine cycle (ORC), an ORC with a vapor-liquid injector (IORC) using zeotropic mixture R601a/R245fa as working fluid is proposed.

Numerical and Experimental Investigation of Supersonic Binary Fluid Ejector Performance

Fluids, 2023
Ejectors are simple mechanical devices with no moving parts which convert the pressure energy of a motive fluid to kinetic energy and generate suction of the secondary fluid. The ability to recover waste heat, to operate using solar power and the ability

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Photoactive Tweezers

Advanced Materials, EarlyView.
A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.

Measurement of Smoke Entrainment Rate and Yield Ratio by a Downward Plume

International Journal of Fire Science and Engineering
In some industrial buildings, ventilation system continues to be operated even after the break of fire in order to keep the necessary pressure differences. In such situations, supplied air at the ceiling creates a downward plume. The plume entrains smoke in the upper layer and move the smoke particles downward.

Ultrathin Hydrogel Membranes Inspired by Soap Films Enable Physiologically Relevant Breathing Lung Models

Advanced Materials, EarlyView.
A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Experimental Investigation and Dynamic Fractal and Multi-fractal Analysis of the Density Current Patterns [PDF]

مهندسی منابع آب, 2020
Density current is caused by a slight density difference with the environmental fluid. These currents are of two-phase current type. These currents are non-linear in nature, which are complex and sensitive to initial conditions.
