Plasmachemical Synthesis and Basic Properties of CoFe2O4 Magnetic Nanoparticles
Cobalt-ferrite (CoFe2O4) nanoparticles (CFNPs) are obtained using direct plasmachemical synthesis in the plasma of a low-pressure arc discharge. The formation of the CFNPs with an average size of 9 nm and a narrow granulometric ...
Synthesis of Nanosized Titanium Oxide and Nitride Through Vacuum Arc Plasma Expansion Technique
Physical vapor deposition techniques such vacuum arc plasma deposition — which are very commonly used in thin film technology — appear to hold much promise for the synthesis of nanocrystalline thin films as well as ...
The impact of urbanization on the transmission of culture and language of the sakha people: a sociological analysis
The article discusses the impact of urbanization on the transmission of the Sakha people’s identity, culture, and language in the Sakha Republic (Yakutia). Based on the results of a sociological survey, the ethno-cultural ...
On the possibility of phase transitions with the formation of SiO2 peroxide forms in the earth mantle and their effect on mantle convection
Based on the hypothesis advanced by S. P. Gabuda that the SiO2 molecule could undergo a transition from the linear form to the isomeric form with a ring-shaped (bent) structure, an idea is proposed that when the mantle ...
Influence of wood density in tree-ring based annual productivity assessments and its errors in Norway spruce
Estimations of tree annual biomass increments are used by a variety of studies related to forest productivity or carbon fluxes. Biomass increment estimations can be easily obtained from diameter surveys or historical ...
Restructuring of plasmonic nanoparticle aggregates with arbitrary particle size distribution in pulsed laser fields
We have studied processes of interaction of pulsed laser radiation with resonant groups of plasmonic nanoparticles (resonant domains) in large colloidal nanoparticle aggregates having different interparticle gaps and ...
Systematics and biology of some species of Micrurapteryx Spuler (Lepidoptera, Gracillariidae) from the Holarctic Region, with re-description of M. caraganella (Hering) from Siberia
During a DNA barcoding campaign of leaf-mining insects from Siberia, a genetically divergent lineage of a gracillariid belonging to the genus Micrurapteryx was discovered, whose larvae developed on Caragana Fabr. and ...
