Particle size characterization is one of the key areas involved in quality assurance. The concept of particle size and size characterization acts as a foundation for all the processes involved in theproduction of a formulation; from manufacturing to quali... see more

The objective of this article is to study the possibilities of enrichment of the iron ore from Jebel Anini and to develop these mineral resources in order to use them in the metallurgical complex of Annaba. Representative samples were taken from Anini iro... see more

This study assesses seasonal particle size distribution (PSD) dynamics inside a waste stabilization ponds (WSP) (Buguruni, Tanzania) to understand settling dynamics of wastewater particles with an interest in helminth eggs. Results indicate that particles... see more

An urban pollutant loading model was used to demonstrate how incorrect assumptions on the particle size distribution (PSD) in urban runoff can alter the design characteristics of stormwater control measures (SCMs) used to remove solids in stormwater. Fiel... see more

In this study, the Box-Behnken Design (BBD) was employed to investigate the effects of wood particle size, pyrolysis temperature, and pyrolysis time on the production of wood vinegar from Indonesia “bengkirai” wood (Shorea laevis Ridl). Characterization o... see more

Settled particles collected in El Paraiso highway tunnel, located at the western Caracas (Venezuela) have been fractionated in five sizes 35, 60, 120, 230 and 325 meshes (500, 250, 125, 60 y 45 µm) and analyzed for carbon, hydrogen, nitrogen and sulphur;... see more

Up to 60–70% of the total textile dyes produced are azo dyes. An example of azo dye is methylene blue, which is commonly used in dyeing wool, silk, and cotton. This substance possessed harmful effects on the environment. Therefore, the removal process is ... see more

Exosomes from Mesenchymal Stem Cells (MSC) is currently one of the highlighted research due to its more specific action on the target tissue. Exosome is one of the MSC Extracellular Vesicle (EVs) that acts as a mediator in the cellular communication. Howe... see more

This study assesses the effect of size, as well as binary and ternary mixtures of three different carbon nanotubes added to Portland cement pastes containing nano-silica. Carbon nanotubes were characterized in terms of size and morphology by transmission ... see more
