Objective: Vitamin E acetate has antioxidant activity that can prevent premature aging of the skin, but it is highly lipophilic (log p±12.2) and potentially degraded. To overcome permeability stability problems, vitamin needs to be developed in Nanostructured Lipid Carrier (NLC), a nano-delivery system based on solid lipid liquid stabilized by surfactants as colloidal system.
 Methods: The...

the hydroxyl radical (oh•) is a powerful oxidant produced as a consequence of cavitation in water. it can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. it can also recombine to form hydrogen peroxide which is very useful in water treatment. in this study, terephthalic acid (ta) and potassium iodide dosimetry were used to quantify and inve...

Heat cure denture base is the most commonly used material for fabrication of removable prosthesis to present day. However difficulties persist in satisfactory due poor mechanical properties which have resulted frequent repairs dental practice. The study aimed investigate effect Zirconium oxide nanoparticles (ZrO2NPs) on flexural strength and porosity its correlation. X-ray diffraction (XRD) was...

The conventional extraction method has low efficiency. This study aims to optimize the ultrasonic-assisted conditions of andrographolide from A. paniculata. A ½ inch ultrasonic probe sonicator was used extract effects time (X1), duty cycle (X2) and amplitude (X3) on yield (Y) were investigated by using response surface methodology. Experiments designed according 3-level 3-factor Box Behnken Des...

In recent years, industries have been investing to develop a potential alternative fuel substitute the depleting fossil fuels which emit noxious emissions. Present work investigated effect of ferrous ferric oxide nano-additive on performance and emission parameters compression ignition engine fuelled with chicken fat methyl ester blends. The was included various blends at different ppm 50, 100,...

The purpose of this experimental study is to evaluate the effects of particle species, surface charge, concentration, preparation technique, and base fluid on thermal transport capability of nanoparticle suspensions (nanofluids). The surface charge was varied by changing the pH value of the fluids. The alumina (Al2O3) and copper oxide (CuO) nanoparticles were dispersed in deionized (DI) water a...

The abilities of various extractants to recover four arsenic species [As(iii), As(v), dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA)] from soils spiked with 20 micro g g(-1) As were investigated. The extractants were water, buffer solutions (citrate and ammonium dihydrogen phosphate), acidic solutions (phosphoric acid and acetic acid), a basic solution (sodium hydroxide) and house...

The medical applications of carbon nanotubes (CNTs) have garnered much attention. However, evaluating the safety of CNTs remains difficult, and no consensus has been reached. Moreover, assessing the biosafety of multi-walled CNTs (MWCNTs), which can become tangled during manufacturing, is challenging because they do not readily disperse. We studied how the dispersion state of tangled MWCNTs aff...
