“…13 The use of alkylamines as the ligating solvent reacted in the microwave at 140 C for 1 minute has been reported, 13 with an inverse correlation between the size of the nanoparticles and the length of the amine used. These ndings are contradicted by Sofronov et al, who employ reaction temperatures of 240 C as it is claimed that the interaction between zinc and selenium only occurs at temperatures above 218 C. 12 Employing a temperature of 240 C is still considerably low, but with this, fast heating of the particles at 500-600 C is still necessary with subsequent injection of alkaline metal halogenides.…”

“…11 The microwave reactor has also been implemented in the formation of zinc selenide nanomaterials, which has numerous advantages over traditional thermal methods including fast and homogeneous heating of the reaction mixture, high speed of interaction, an inverse temperature gradient and the possibility of fast selection of chemical reaction conditions. 12 Microwave irradiation is different from other techniques in that it does not rely on black body radiation to heat the reaction mixture, which allows for greater advantages for colloidal nanostructured materials to be formed. The synthesis is efficient, with a uniform nucleation and growth process, without suffering sharp thermal gradient effects.…”

The magnetic particles of iron oxides are promising materials for the purification of water from ions of heavy metals and radionuclides. Their advantage compared to other sorbents is the ability to extract by applied magnetic field, which greatly simplifies the task of extraction, separation and processing in cleaning technologies. The aim of this work is investigation of temperature and concentration of iron in the solution effect on the phase composition, nanoparticle size and their magnetization. Phase magnetite in the sample increases with increasing temperature and the magnetization decreases slightly with increasing the initial concentration of iron in solution. We found that regardless of the conditions of deposition formed spherical particles whose average size ranges from 7 to 15 nm. The sorptive capacity of the particles is virtually independent of the phase composition and for cobalt is about 18 mg/g. For sorption-based material magnetic particles Fe3O4 recommended to carry out the deposition process at a temperature not lower than 80°C. The concentration of iron in solution must be within 0,15–0,3M. The particles obtained contain in their composition at least 90 wt.% of magnetite phase and are characterized by a magnetization in the range of 65–70 A·m2/kg. Also in the paper is comparing efficiency of extraction and sorption capacity for cobalt particles by different phase of magnetite and hematite.

CdS synthesis by plasma-enhanced microwave physical vapor transport (PMPVT) has been developed in this work. The photoluminescence (PL), absorbance, Raman spectra and the mechanism of CdS crystal growth have been investigated. Furthermore, plasma-enhanced microwave chemical vapour transport (PMCVT) synthesis of CdS with additional chemical transport agents has been explored. In addition, other II-VI chalcogenides were also synthesized by PMPVT.
