An Insightful Study on SMEDDS Challenges and Potential Strategies
Abstract: Self-microemulsifying drug delivery systems (SMEDDS) have gained attention as an effective approach to enhance the bioavailability of poorly water-soluble drugs. They are innovative lipid-based formulations designed to enhance the solubility, bioavailability, and therapeutic efficacy of poorly water-soluble drugs. The development of SMEDDS involves systematic selection of components based on solubility and emulsification efficiency, followed by optimization of ratios using pseudo-ternary phase diagrams. The resulting formulations are evaluated for droplet size, …

Atomizers in spray dryers: a review
Abstract: Atomization is the most important step in spray drying that defines the properties of liquid droplets after spraying, resulting in various forms of the dry product - from fine powders to granules. It basically refers to the disintegration of the liquid into droplets in the presence of a drying gas circulating in the medium, increasing its surface area until the droplet becomes unstable and disintegrates. The choice of the atomizer's …

Review and Design of Voltage Sag Compensation Using Improved DVR System with Proportional Integral Controller
Abstract: The aim of this investigation is to remunerate voltage inthree-stage power systems during voltage sag conditions induced bybalanced and unsymmetrical deficiencies in power distributionsystems or offices in plants. Voltage plunges (also known as "voltagesags") are abrupt drops in voltage size. Their definition is usuallyanywhere between a couple of power-system recurrence trends and acouple of moments. The popularity of voltage plunges stemsprimarily from their effect on end-client hardware. Mechanicalprocesses can fail …

Review on Main Equations for Measuring Spray Properties in Centrifugal Injectors
Abstract: The method of fuel injection has a significant effect on the stability and proper mixing of fuel and oxidizer, which is done by the injector. In other words, the injector is a device that converts fluid into droplets. The faster and better the particle crushing rate, the faster the fluid particles will evaporate, resulting in higher thermal efficiency and higher thrust force. Therefore, how to inject fuel into the combustion …

Characterization of Nanofluids Using Experimental and Analytical Methods for Different Concentrations
Abstract: A fluid containing nanometer-sized nanoparticles is called nanofluid. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. Nanofluids are a new class of fluids engineered by dispersing nanometer-sized materials (nanoparticles, nanofibers, nanotubes, nanorods, nanosheet, or droplets) in base fluids. They are two-phase systems with one phase (solid phase) in another (liquid phase). For a two-phase system, there are some important issues we have to face. One of …
