Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

In this paper, HSC software was used to perform a thermodynamic analysis of A5083/ZrO2 metal matrix composite to predict the phases which formed during the manufacturing processes (vortex method). The base matrix was purchased commercially and the zirconia particles were extracted from Egyptian zircon as a reinforcing material by alkaline fusion technique. The base material was melted in an electric furnace at 750°C, and the extracted zirconia particles were added while stirring. ...

This paper focuses on the difference between the effect of heating and reheating on sunflower oil properties by using carbon dioxide laser and electrical heater. Two samples of sunflower oil were heated and reheated with carbon dioxide laser beaming up to 50°C, which takes 30 minutes; another two samples were heated and reheated up to 250°C using electrical heater in two minutes, along with an unheated control sample at ambient conditions. Chemical properties like acid value, free fatty ...

In this paper we used BSA Langmuir monolayer as templates to study the effect of solute concentration on regulated biomineralization of calcium carbonate. During the crystallization process, it is found that the morphology of the calcium carbonate can be strongly affected by the solute concentration in presence of BSA Langmuir monolayer. X-ray Diffraction (XRD) results show that the crystal of calcium carbonate formed is all the calcite phase with a higher orientation. SEM images show that the m...

Oriented calcium carbonate crystals have been grown beneath bovine serum albumin (BSA) Langmuir monolayers at the air-solution interface from supersaturated calcium bicarbonate solutions. The calcium carbonate prepared was characterized by XRD, SEM, TEM and SAED. It was found the crystal morphologies changed from amorphous calcium carbonate (ACC) to regular hemispherical calcite crystals with the prolonging of the time. These observations suggest that the process is step by step, during which th...

In the recent, filler-polymer composites researches have been on the rise due to its implication to electromagnetic interference (EMI) applications. The composition, morphology and surface rheology of the filler-polymer composites play an immense role in determining the electrical, mechanical, and optical properties. In this paper, the preparation and characterization of micro-composites of wood (biodegradable waste material)/polycaprolactone (PCL) composites a

Changes in the mechanical properties of Acrylonitrile-Butadiene Rubber (NBR)/Poly (vinyl chloride) resin binary blend were investigated. Poly (vinyl chloride) resin additives were within range (0 - 70) wt.%, and the measured mechanical properties included tensile strength, elongation, and compression strength. The obtained results showed that the tensile and elongation value of NBR starts to decrease with the addition of PVC resin

Hybrid composite material consists rubber matrix reinforced by polymer waste stripes is introduced in this study. Hardness and adhesion of Acry-lonitrile Butadiene Rubber-Polyethylene Terephthalate (PET) waste com-posite have been investigated. The study included the relationship between these properties and the percentage of PET’sadditives (0 - 100 pphr) as a reinforcement material. The obtai
