The lavender flowers and their essential oil are widely used in therapy Romania the European Community. Since Pharmacopoeia only allows use of Lavandula sp for medicinal purposes, objective this study was to investigate chemical composition angustifolia extracts obtained by ultrasound-assisted extraction, rapid pressurized extraction at 6.7 bar, subcritical fluid extraction. solvents first two methods were mixtures water alcohol, glycerin, propylene glycol. These analyzed high-performance...

The study aims to investigate the chemical composition of airborne particulate matter with size below 2.5 �m (PM2.5) collected from Targoviste City area, in summer 2015. For this consideration eleven representative points have been chosen for sampling. This research provides interesting data which can clarify relationship between PM2.5 exposure and negative effects on human health at urban area level. Three analytical techniques developed qualitative, quantitative morphological...

This study aims to investigate the chemical composition of nineteen painted pottery fragments belonging Eneolithic Petresti culture in order identify relationship between ceramic artifacts and potential clay sources located proximity archeological site. Two analytical techniques (attenuated total reflection-Fourier transform infrared spectrometry (ATR-FTIR) scanning electron microscopy coupled with energy dispersive (SEM-EDS) have been used achieve these goals. SEM-EDS was especially useful...

AISI 316 steel has good corrosion behavior and high-temperature stability, but often prolonged exposure to temperatures close 700 °C in aggressive environments (e.g., boilers furnaces, nuclear installations) can cause problems that lead accelerated degradation of components.
