Drop breakage in a single‐pass through vortex‐based cavitation device: Experiments and modeling

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Liquid–liquid emulsions are used in many sectors such as personal care, home care, and food products. There is an increasing need for developing compact and modular devices for producing emulsions with desired droplet size distribution (DSD). In this work, we have experimentally and computationally investigated an application of vortex‐based ...

Coupling hydrothermal liquefaction and aqueous phase reforming for integrated production of biocrude and renewable H2

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Direct Observation of Dry Etch‐Induced Selectivity Tailoring of Alkylate Inhibition Layer Using DMATMS Vapor

Advanced Materials Interfaces, EarlyView.
This study demonstrates that tailoring surface ─OH groups on SiO2 and SiNx via dry etching significantly enhances the selectivity of DMATMS adsorption, achieving a 92.2% selectivity in subsequent Ru layer growth. In situ spectroscopy reveals that removal of ─OH groups reduce DMATMS reactivity on SiNx but not on SiO2, providing insights for improving ...

The Influence of the Aortic Root Geometry on Flow Characteristics of a Bileaflet Mechanical Heart Valve [PDF]

arXiv, 2018
Bileaflet mechanical heart valves have one of the most successful valve designs for more than 30 years. These valves are often used for aortic valve replacement, where the geometry of the aortic root sinuses may vary due to valvular disease and affect valve performance. Common geometrical sinus changes may be due to valve stenosis and insufficiency. In
