Bismuth ferrite (BiFeO 3 ) thin films with Bi 2 O 3 buffer layers were prepared on Si/SiO 2 /TiO 2 /Pt substrates by sol–gel‐derived spin‐coating method. The structural and electrical properties of BiFeO 3 was effectively improved by adding a Bi 2 O 3 buffer layers either at Pt/BiFeO 3 interface or on BiFeO 3 surface,…
We report here cetyl alcohol-promoted synthesis of spherical CuCr <sub>2</sub> O <sub>4</sub> spinel nanoparticles with almost uniform morphology, prepared hydrothermally.
A series of meso -ferrocenyl-porphyrin dyads linked by four different π-conjugated bridging units (directly bound, vinyl, ethynyl, and phenyl) have been synthesized to investigate the influence of the conjugated linker on both the electronic and photochemical properties of the porphyrin chromophore. The basic structur…
Two-phase multiferroic heterostructures composed of room-temperature ferroelectric BaTiO3 (BTO) and ferromagnetic La0.7Sr0.3MnO3 (LSMO) epitaxial thin films were grown on technologically important substrate Si (100). Bilayers of BTO/LSMO thin films display ferromagnetic Curie transition temperatures of ∼350 K, close t…
The properties of ceramic products are determined not only by the composition and structure of the phases but also by the arrangement of the phases. This arrangement of the phases can be determined by studying the microstructures. The arrangement of the phases or their distribution depends on the initial fabrication t…
Cadmium selenide nanocrystals were prepared in water phase through facile wet chemistry technique with thioglycolic acid (TGA) acting as capping agent. Structures were characterized using X-ray diffraction (XRD), UV-vis absorption and photoluminescence spectroscopies. Depending on synthesis conditions nanoparticles ex…
Here we present a formal description of Biremis panamae Barka, Witkowski et Weisenborn sp. nov., which was isolated from the marine littoral environment of the Pacific Ocean coast of Panama. The description is based on morphology (light and electron microscopy) and the rbcL, psbC and SSU sequences of one clone of this…
Vibrational spectroscopy usually provides structural information averaged over many molecules. We report a larger peak position variation and reproducibly smaller FWHM of TERS spectra compared to SERS spectra indicating that the number of molecules excited in a TERS experiment is extremely low. Thus, orientational ave…
The effect of sodium dodecyl sulfate (SDS) on the poly(N-isopropylacrylamide) (PNIPAM) tethered to nanoparticles was experimentally investigated using dynamic light scattering below the lower critical solution temperature. A mean-field analytical model was used to calculate the parameters of interfacial PNIPAM-SDS com…
Stable metal nanoparticles in tetraalkylphosphonium ionic liquids can catalyze hydrogenations, as well as phenol hydrodeoxygenation, owing to presence of adventitious borates.
Among severe plastic deformation methods, groove pressing is one of the prominent techniques for producing ultra-fine grained sheet materials. This process consists of imposing repetitive severe plastic deformation on the plate or sheet metals through alternate pressing. In the current study, a 2 mm pure Cu sheet has…
First-principles calculations based on density functional theory showed that the thermoelectric performance of single-atomic-layer phosphorus, referred to as phosphorene, is significantly enhanced by the application of tensile strain along a particular direction. Phosphorene subjected to a 10% strain exhibits a very l…
In the temperature range of 280 to 350 K, there is a solid-to-solid phase transition for each complex, which is further evidenced by four thermal circulating processes with the scanning rate of 10 K min <sup>−1</sup> .
We report the discovery of an antiferromagnetic coupling of the magnetic moment of chromium(II) tetraphenyl-porphyrin (CrTPP) molecules to the magnetization of the clean ferromagnetic Co(001) substrate. We assign this unusual molecule-substrate exchange coupling to the less than half-filled chromium $3d$ orbitals inte…
A series of CuO-V2O5/TiO2 catalysts with different Cu contents were prepared by wet impregnation method and used in selective catalytic reduction of NO with NH3. The aim of this design was to improve the low-temperature selective catalytic reduction (SCR) performance and broaden the temperature window compared to V2O5…
Abstract In the first of a series of papers on the iodine(V) oxide system, the chemical and physical properties associated with iodine(V) oxide in its anhydride (I 2 O 5 ) and hydrated states (HI 3 O 8 and HIO 3 ) are examined. The three forms of the oxide have been investigated utilizing differential scanning calorim…
We present a semianalytical point-dipole method that uses Ewald lattice summation to find the dispersion relation of guided plasmonic and bianisotropic modes in metasurfaces composed of two-dimensional (2D) periodic lattices of arbitrarily strongly scattering magnetoelectric dipole scatterers. This method takes into a…
Formation and properties of Pd nanoparticles have been investigated in situ in the temperature range between 186 and 483 K by X-ray absorption fine structure (XAFS) spectroscopy and by ex situ electron microscopy. Results of the experiments conducted under hydrogen and helium atmospheres were compared, in order to ill…
Electrochemically reduced graphene oxide film catalyzed electroless deposition of gold nanoparticles.
Enantioselective functionalization of fluorescent dye loaded periodic mesoporous organosilicas with <sc>d</sc> ( <sc>l</sc> )-mannose and the preparation of their self-assembled monolayers are described. Stereoselective interactions of these monolayers with different cell types are demonstrated.
