Conductive polyaniline (PANi)/Fe3O4 is coated on the MnFe2O4 nanocomposite with multi core shell structure was synthesized by in-situ polymerization in the presence of dodecyl benzene sulfonic acid (DBSA) as the surfactant and dopant and ammonium persulfate (APS) as the oxidant. The structure and magnetic properties o…
We perform fully relativistic first principles calculations of the exchange interactions and the magnetocrystalline anisotropy energy (MAE) in an Fe/FePt/Fe sandwich system in order to elucidate how the presence of Fe/FePt (soft/hard magnetic) interfaces impacts on the magnetic properties of Fe/FePt/Fe multilayers. Th…
In the three-dimensional topological insulator (TI), the physics of doped semiconductors exists literally side-by-side with the physics of ultra-relativistic Dirac fermions. This unusual pairing creates a novel playground for studying the interplay between disorder and electronic transport. In this mini-review we focu…
Recent theoretical calculations and experimental results suggest that the strongly correlated material SmB$_{6}$ may be a realization of a topological Kondo insulator. We have performed an angle-resolved photoemission spectroscopy study on SmB$_{6}$ in order to elucidate elements of the electronic structure relevant t…
Bismuth selenide is both a thermoelectric material and topological insulator. Defects and dopants create conduction in thermoelectric applications. However, such defects may degrade the performance as a topological insulator (TI). Magnetic impurities such as iron open a band gap at the Dirac point on the surface. Sinc…
The use of magnesium alloys as degradable metals for biomedical applications is a topic of ongoing research and the demand for multifunctional materials is increasing. Hence, binary Mg-Ag alloys were designed as implant materials to combine the favourable properties of magnesium with the well-known antibacterial prope…
By Swedish law it is the obligation of the nuclear power utilities to satisfactorily demonstrate how a nuclear power plant can be safely decommissioned and dismantled when it is no longer in service as well as calculate the estimated cost of decommissioning of the nuclear power plant. Svensk Kaernbraenslehantering AB…
Collagen is the main ingredient in the gelatin manufacture. The purpose of the study was todetermine the pH value, the swelling percentage and collagen yield of chicken shank bones which weresoaked by different HCl concentration and soaking time. The pH value and swelling percentage ofchicken shank bones are indicator…
Graphene nanomaterials are actively used in electronics and materials science as elements of electric circuits and both structural and storage components. Their unique structure and electronic properties allow for a wide variety of applications (i.e., electron and thermal conductivity, ion transport, ion storage, and…
A comparative study is performed of the catalytic activity of nanosized nickel deposited on detonation synthesis nanodiamond (DND) and coal (C SUG ) produced by burning sugar and crystalline quartz in the hydrogenation of acetylene. Nanosized nickel is obtained through the thermal decomposition of nickel formate under…
The results of investigations of porous glasses (PG) and porous glasses-ammonium hydrogen sulfate ferroelectric nanocomposites (AHS-PG) are presented. On the basis of dielectric and calorimetric measurements it was shown that in the AHS-PG nanocomposites with average pore size of 44, 68, 95, and 320 nm the anomalies o…
Aggregation of Fe(III)-tetra-(4-sulfonatophenyl)-porphyrin (Fe(III)TPPS) was studied in the presence of block copolymers, poly(ethylene glycol)-block-poly(4-vinylpyridine) (PEG-b-P4VP), poly(ethylene glycol)-block-poly(2-(dimethylamino)ethyl methylacrylate) (PEG-b-PDMAEMA), and poly(ethylene glycol)-block-poly(β-cyclo…
It is found that ozone treatment of aspen wood leads to changes in its structural characteristics, i.e., its specific surface area and the crystallinity index of cellulose. Using optical microscopy, it is shown that ozonation is accompanied by a decrease in the average size and visible surface of wood particles. The v…
The paper deals with the studies of Langmuir–Blodgett (LB) corrole and corrole-fullerene dyad layers with the use of electronic and vibrational absorption and reflection–absorption spectroscopies. UV–vis and IR spectra were recorded with polarized and unpolarized light to evaluate orientation of the molecules with res…
The interaction of water with Fe 3 O 4 (001) films has been studied by using Auger electron spectroscopy, low-energy electron diffraction, ultraviolet photoelectron spectroscopy, and high-resolution electron energy loss spectroscopy. The water molecules can be dissociated at temperatures below room temperature. The OH…
Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(styrene sulfonate) (PSS) has a variety of chemical and biomedical applications. The application of PEDOT/PSS polymers in drug delivery has attracted attention. However, whether conducting polymers of PEDOT/PSS could be used for dopamine delivery has not clear. I…
Three perovskite-structured ceramic phases Ba1−3x Pr2x Ti0.95Sn0.05O3 (BPTS-x) with x=0.01, 0.03, and 0.05 have been synthesized by solid-state reaction method. Obtained BPTS-x ceramics were investigated by X-ray diffraction and dielectric properties measurements. Analysis of all the ceramic samples using X-ray diffra…
To comparatively investigate the cytotoxicities of nanomaterials in circulation, in this study, three different types of nanoparticles (NPs; mesoporous SiO2, Fe3O4, and TiO2) with diameters of around 100 nm were synthesized. The morphologies, crystalline phases, and zeta potentials of those NPs were characterized by s…
Designing scaffolds to modulate protein adsorption is a key to building advanced scaffolds for tissue regeneration. Protein adsorption to tissue engineering scaffolds is critical in early cell attachment, survival, and eventual proliferation. The goal of this study is to examine the effect of functionalization on fibr…
