Development of an Impinging-jet Fuel-injection Valve Nozzle [PDF]

During an investigation to determine the possibilities and limitations of a two-stroke-cycle engine and ignition, it was necessary to develop a fuel injection valve nozzle to produce a disk-shaped, well dispersed spray.

Catalyst Layer Modifications for Enhanced Performance of Fluorine‐Free Proton Exchange Membrane Fuel Cells

Advanced Energy and Sustainability Research, EarlyView.
Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, EarlyView.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG$$ {c}_{\mathrm{AG}} $$. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation.

A Cost‐Effective Hybrid Method For Homogeneous Matrix Coating in Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry Imaging Using Simultaneous Spin and Spray Deposition

Analysis &Sensing, EarlyView.
This study introduces an in‐house spin coater for matrix‐assisted laser desorption/ionization mass spectrometry imaging, providing homogeneous matrix deposition via simultaneous spray and spin. The approach yields reproducible signals and clear metabolite distributions in complex tissues.

Evaluation of aerosolized medications during parabolic flight maneuvers [PDF]

The goal was to visually evaluate the effect gravity has on delivery of medications by the use of various aerosol devices. During parabolic flight the same four aerosols were retested as performed in studio ground tests.

Migration and Dispersion Evolution of Exhaled Aerosol in a Ward Under Different Ventilation Modes

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wards with special functions and closure will have a higher risk of viral transmission as aerosols are an important mode of transmission for the SARS‐CoV‐2 virus. In this study, an experimental platform was built to establish the relevant parameters of the aerosol model and the aerosol propagation model according to the experimental results ...

Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...
