Cobalt-containing nanoparticles have been prepared via thermal decomposition of cobalt acetate on the surface of poly(tetrafluoroethylene) (PTFE) microgranules forming a fluidized bed over the surface of hot mineral oil. Using transmission electron microscopy, the average size of the cobalt-containing nanoparticles has been determined to be 3.6 nm. The composition and structure of the nanoparticle

We have prepared nanomaterials consisting of SiO 2 microgranules and Fe-containing nanoparticles on their surface and determined the size and composition of the nanoparticles. The nanoparticles are shown to have a core-shell structure (α-Fe core and γ-Fe 2O 3 shell). The α-Fe core and Fe 2O 3 shell are responsible, respectively, for the broad and narrow lines in the EMR spectrum of the nanoparticl

Nanosized copper-containing particles stabilized on the surface of polymer nanograins were obtained by thermal decomposition of copper-containing precursors in a fluidized bed of ultradispersed polytetrafluoroethylene. Transmission electron microscopy showed that the average size of nanoparticles is 10-12 nm. The structure of the particles was determined by EXAFS, EPR, and X-ray powder diffraction

In this work we demonstrate that it is possible to create new magnetic material based on metal-containing nanoparticles stabilized on the surface of polytetrafluoroethylene nanogranules. Magnetic properties of these materials have been investigated. The materials were prepared by a method of thermal decomposition of metal-containing compounds in the heated polytetrafluoroethylene-oil system. Trans

Nanoparticles of Fe1-xMnx (0.07 < x < 0.20) alloys are studied using electron magnetic resonance in the temperature range 295-500 K. It is found that the temperature and manganese concentration in the nanoparticles have a noticeable effect on their electron magnetic resonance spectra. It is suggested that the Fe1-xMnx nanoparticles contain phases with different magnetic properties and that the rel

Nanocomposites of high-pressure polyethylene and zinc oxide nanoparticles are synthesized through thermal decomposition of zinc acetate. The phase composition of the nanocomposites is determined by x-ray diffraction (XRD), and the average size of ZnO nanoparticles is evaluated by transmission electron microscopy. The average size of the nanoparticles varies from 1 to 10 nm, depending on the ZnO co

The aim of this presentation is to examine the complex reception history of Astrid Lindgren's classic children's book “Pippi Longstocking” in the GDR based on the appearance and paper quality of the various editions. “Pippi Longstockning” was published in two different editions in 1975 and 1988 by the East Berlin Children's Book Publishing House (Kinderbuchverlag Berlin). The differences between t

In recent years, school strikes and street protests for climate justice have drawn international attention to young people's mobilisation and activism on global issues. This article addresses the need to map the history of global awareness among young people by exploring the origins of the Operation Dagsverke (Operation Day's Work) campaign in Sweden during the early 1960s. Drawing primarily on ma

Tailoring the activity of an organometallic catalyst usually requires a targeted ligand design. Tuning the ligand bulkiness and tuning the electronic properties are popular approaches, which are somehow interdependent because substituents of different sizes within ligands can determine inter alia the occurrence of different degrees of inductive effects. Ligand basicity, in particular, turned o

Using flow cytometry and microsatellite DNA analysis (MSDA), we studied hybrids between Rubus caesius and various other Rubus species, with an emphasis on Sweden. We show that hybrids between Rubus caesius and Rubus sect. Corylifolii arise easily. They show a large variation in morphology, but can normally be recognised by a number of characters. They are typically hexaploids, but ~13% of the hy

The effect of long-term implantation on metabolically active devices is of utmost importance for not only the success of implanted glucose sensors used in diabetic therapy, but also for the development of artificial tissues and encapsulated cell devices. Such devices are dependent on the constant, predictable supply of metabolites from the local vasculature. Long-term implantation leads to the for

This chapter challenges the view that rising living standards and other indexes of progress in Sweden merely are rewards of technological development, successful industries, and a hard-working population, disconnected from the facts of European colonial history and the severely unequal conditions of contemporary world society. The European context of Swedish industrialisation and the large ecologi

Abstract in French« Un français transformé en suédois ». Voilà comment Alf Lombard se décrivait lui-même. Il est né à Paris, son père était français et sa mère était suédoise. Il manifestait un intérêt global pour les langues romanes, mais à part le français et l’italien, c’est surtout le roumain qui était son domaine préféré. Les articles sur le français, l’italien et le roumain dans ce volume re
