Sprays are dynamic collections of droplets dispersed in a gas. They are used in many industrial and agricultural applications such as manufacturing processes, fuel injection, painting, and crop protection. Furthermore, ‘‘Sprays are among the most intellectually

Our lab recently introduced a methodology to determine the average velocity and flow behaviour index of laminar pipe flow using simple magnetic resonance techniques. The knowledge of these two parameters provides the information needed to reconstruct the flow velocity profile. However, as the flow velocity increases, the flow will begin to develop turbulence. For a given fluid moving through...

Low-field portable magnetic resonance has several advantages over conventional high-field scanners, in that they are low cost, simple to construct, and readily employed outside a dedicated research lab. Numerous magnet designs have been created in recent decades which have been used for material characterization to improve industrial processes, and medical procedures. Portable magnet designs...

Magnetic resonance imaging of short signal-lifetime samples comes with several challenges1, namely lower signal and the need for short acquisition windows. The apparent transverse relaxation time ($T_2^*$) of water-content in cement paste has been measured2 to be <0.3ms at 3T: this suggests imaging at low field (<0.5T) where $T_2^*$ is expected to be... -

An exploratory multinuclear MR and MRI study was performed on lithium-ion battery cells with $^7$Li, $^{19}$F, and $^1$H measurements. A variable field superconducting magnet with a fixed frequency parallel-plate RF probe was employed in the study. The magnet's magnetic field was changed to set the resonance frequency of each nucleus to the fixed RF probe frequency of 33.7 MHz. Two...

Reservoir rocks which trap oil and gas have been extensively studied for decades, due to their importance in the petroleum industry. Pore size is an important petrophysical property controlling fluid storage and fluid transport in reservoir rocks. Many techniques such as scanning electron microscopy (SEM), X-ray, and mercury injection capillary porosimetry (MICP), have been applied to estimate...
