In this work, a combination of an acoustic emission (AE) technique and a machine learning (ML) algorithm(Random Forest (RF) and Gradient Boosting Regressor (GBR)) is developed to characterize the particle sizedistribution in gas-solid fluidized bed reactors. A theoretical approach to explain the generation of acousticemission signal in gas-solid fl...
Advanced ultrasound techniques were used to study liquid–liquid dispersed flows formed in impinging jets confined in small channels. Ultrasound speed and attenuation coefficient spectra of the propagated sound waves were used to obtain volume fraction and drop size distributions, respectively. The results were compared against drop size distributio...
We highlight the work of a multi-university collaborative programme, PREMIERE (PREdictive Modelling with QuantIfication of UncERtainty for MultiphasE Systems), which is at the intersection of multi-physics and machine learning, aiming to enhance predictive capabilities in complex multiphase flow systems across diverse length and time scales. Our co...
This paper delineates the development and application of non-intrusive diagnostic ultrasound (US) techniques for the measurement of the drop size distribution (DSD) and the drop volume fraction in dispersed liquid-liquid flows. The techniques used here are based on the measurement of the speed and the attenuation coefficient of the propagated ultra...
Acoustofluidics is an emerging interdisciplinary research field that involves the integration of acoustics and microfluidics to address challenges in various scientific areas. This technology has proven to be a powerful tool for separating biological targets from complex fluids due to its label-free, biocompatible, and contact-free nature. Consider...
Extended Abstract The characterization of particle in solid-gas flow is of great importance in many industrial sectors such as nuclear energy, and pharmaceutical industries. Acoustic techniques can provide a complementary information to other techniques e.g., optical sensors, x-ray, MRI, and acoustic techniques are relatively cheap, can be applied...
This paper describes an application of ultrasound techniques to solid-liquid fluidized beds. The ultrasonic methods, experimental setups, and the signal processing for obtaining velocity profiles, particle size distribution, and solids volume fraction are discussed. The techniques are based on the measurement of the ultrasound attenuation coefficie...
The characterisation of dispersed flows is of great importance to many industrial sectors, including energy, and pharmaceutical industries. Recently, acoustic techniques have attracted considerable attention for the characterization of dispersed particle flows. This is attributed to their ability to obtain measurements in real-time and at high part...
This paper describes a first application of ultrasound techniques to solid-liquid fluidized beds. The ultrasonic methods, experimental setups, and the signal processing for obtaining velocity profiles, particle size distribution, and solids volume fraction are discussed. The techniques are based on the measurement of the ultrasound attenuation coef...
Acoustic methods applied to opaque systems have attracted the attention of researchers in fluid mechanics. In particular, owing to their ability to characterise in real-time, non-transparent and highly concentrated fluid-particle systems, they have been applied to the study of complex multiphase flows such as fluidised beds. This paper gives an ove...
Zika virus is a member of the family of Flaviviridae, which is primarily spread to humans by mosquito bites. It has been linked to microcephaly in neonates, and as such, it poses a significant risk to human pregnancy. Zika virus infection is also implicated in other severe neurological disorders such as Guillain-Barre syndrome. There is currently n...
Ultrasound vibration potential (UVP) is an electroacoustic phenomenon due to ultrasound applied to the colloid particles and ionic electrolyte. Particles/ions in electrolyte carry electrical charges. When excited, charged particles/ions vibrated and generate a secondary electric field that produces the so-called ultrasound vibration potential compr...
Ultrasound vibration potential (UVP) is an electric signal generated from the vibration of particles or ions along with the trajectory of the ultrasound pulses travelling through a colloidal suspension or ionic electrolyte. Therefore, it may be used to characterize or image the physiochemical property of particles or ions. This paper presents a mod...
Colloid vibration potential Imaging (CVPI) refers to the signal generated from the vibration of nanoparticles or ions in electrolyte (or tissue), which has a fundamental difference from the conventional ultrasound reflection detection (URD) based imaging technology. In this paper we demonstrate the super capability of CVP signal (or as one dimensio...
Ultrasound Vibration Potential (UVP) is an electric signal generated when ultrasound pulses travel through a colloidal suspension or ionic electrolyte. The electric potential can be measured, providing information useful to characterize the nanoparticles and ionic electrolytes in engineering and particularly, complimentary information to convention...

Nitrate is an anion of major importance particularly in biological areas. Excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. The effects of excessive quantities of nitrate in water are well known. In this research structural modification of natural clinoptilolite by isomorphic substitution was performed. I...
