A mathematical model for microbubble dissolution in an aqueous medium containing dissolved gases is presented. None of the models available in the literature take into account the influence of shell elasticity (Es), variation ...

Influence of surface modification on wettability and surface energy characteristics of three micron size pharmaceutical excipient powders was studied using hydrophilic and hydrophobic grades of nano-silica. The wetting ...

Poor aqueous solubility of drug molecules is a major challenge for the pharmaceutical scientist involved in drug development. Particle size reduction to nanoscale appears as an effective and versatile option for solubility ...

In any process control study, the first step is to develop a reliable process model. This model can then be used for process control and other process engineering tasks. Further, kinetic study is the heart of the process ...

Liquid crystals are a state of matter between solid and liquid which act as tunable solvents for particles self-assembly. These self-assembled structures can have unique mechanical, optical, electrical and magnetic properties ...

Multiphase systems are ubiquitous in industrial applications aimed at the generation of products either by chemical/biological reaction or physical separation based on density, electrical charge or surface properties such ...

In this study the transition from homogeneous to heterogeneous flow in a solid-liquid fluidized bed (SLFB) is examined both experimentally and numerically. The experimental apparatus comprised a refractive index-matched ...

Modern chemical plants consist of a number of integrated and interlinked process units. When an abnormal situation occurs, the automation system alerts the operators through alarms. In this work, we introduce a new type ...

This work presents a new look at the existing data-based and non-intrusive PI (proportional-integral) controller tuning assessment methods for SISO (single-input single-output) systems under regulatory control. Poorly tuned ...
