Thistle oil (INCI: Silybum marianum seed oil) is known as an anti-oxidant, moisturizing and skin regenerating cosmetic raw material. Nanoemulsions are a new form of cosmetic product showing very good user properties (ease of spreading over the skin with no greasy feeling). Moreover, due to their structure, they can also transport both hydrophilic and hydrophobic active substances to the skin. T...

Evaluation of cytotoxicity, photoluminescence, bio-imaging, and sonosensitizing properties of silicon nanoparticles (SiNPs) prepared by ultrasound grinding of porous silicon nanowires (SiNWs) have been investigated. SiNWs were formed by metal (silver)-assisted wet chemical etching of heavily boron-doped (100)-oriented single crystalline silicon wafers. The prepared SiNWs and aqueous suspensions...

tea is one of the most important medicinal plants which have a considerable effect on the treatment of cardiovascular disease and cancer. the drying process of tea leaves is carried out by hot air flow which consumes high level energy. the aim of the recent research was to investigate the procedure of high power ultrasound-assisted drying process of tea leaves. hybrid variety of chinese tea was...

A simple and efficient method for speciation and determination of iron in different water samples was developed. The method is based on ionic liquid ultrasound assisted dispersive liquid–liquid microextraction (IL-USADLLME) followed by spectrophotometric determination. Fe(II) is complexed with 2,4,6-tri(2’-pyridyl)-l,3,5-triazine (TPTZ), neutralized through ion pair formation with sodium dodecy...

in this research, a rapid, reliable and selective dispersive liquid-liquid microextraction (dllme) followed by direct injection of microdroplet to graphite furnace atomic absorption spectrometry (gf-aas) method for the determination of ultra-trace amounts of ag(i) was developed. effect of the important experimental parameters on the extraction efficiency of ag(i) was investigated using response...

Bisphenol A (BPA), an alkylphenolic compound, is one of the most polluting and hazardous organic chemicals. Its routine detection is, however, still rather expensive due to high-cost equipment. In this context, we applied effect caused by BPA optical properties surfactant-stabilized silver nanoparticles further modified with use ammonia (AgNP-NH3) develop a simple quantitative approach for dete...
