Abstract Many plants have medicinal properties due to substances known as phytochemicals. To utilize these in practice, numerous procedures, such extraction, isolation and characterization methods toxicology bioactivity studies, must be designed implemented. Integrated approach process Carpobrotus edulis , a weed plant widely spread Portugal, was developed into closed loop of two processes: microwave assisted extraction (MAE) activation (MAA), produce both phytochemicals biochar. The use MAE...
The design of lead-free ceramics for piezoelectric energy harvesting applications has become a hot topic. Among these materials, Ba0.85Ca0.15Zr0.10Ti0.90O3 (BCZT) and BaTi0.89Sn0.11O3 (BTSn) are considered as potential candidates due to their enhanced properties. Here, the structural, electrical, properties (1 - x)Ba0.85Ca0.15Zr0.10Ti0.90O3-xBaTi0.89Sn0.11O3 (xBTSn, x = 0.2, 0.4 0.6) system investigated. A systematic study structural xBTSn samples was carried out using X-ray diffraction,...
Structure, optical and photocatalytic properties for wide band gap oxide doped zinc are investigated by XRD, ESR UV-visible spectroscopy.It was shown the introduction of Al2O3 or ZrO2 led to form structural defects in matrix.According data a small amount (0.01 mol.%) ZnO forms donor nature, while same matrix forming as acceptor defects.Observed tail shift confirmed data.It increasing structure increase activity phenol degradation.It dopant types also determined kind intermediates degradation...
