The paper presents a method comparison for the prediction of zero-field splitting (ZFS) parameters in a series of Mn (II) coordination complexes. The test set consists of Mn (II) complexes that are experimentally well-characterized by X-ray diffraction and high-field electron paramagnetic resonance. Their ZFS paramete…
An Fe–Mn–Si–Cr shape memory alloy is applied to make crane rail fishplates. The shape recovery of the reverse martensite transformation from hcp to fcc is utilised to connect finite lengths of rail. Rails connected by normal steel fishplates gradually become separated at the joint and can be damaged by broken flakes i…
BACKGROUND: Biomimetism of synthetic biomaterials can be carried out at different levels, such as composition, structure, morphology, bulk and surface chemical-physical properties. Biomaterials can be turned into biomimetic imprinting of all these characteristics in order not only to optimise their interaction with bi…
We calculate the dispersion equations for magnetoplasmons in a single layer, a pair of parallel layers, a graphite bilayer, and a superlattice of graphene layers in a perpendicular magnetic field. We demonstrate the feasibility of a drift-induced instability of magnetoplasmons. The magnetoplasmon instability in a supe…
AIM: Functional analyses of water-dispersed carbon nanohorns with antitumor activity were performed to explore their potential as a drug carrier for local cancer chemotherapy. MATERIALS & METHODS: Water-dispersed carbon nanohorns were prepared through adsorption of polyethylene glycol-doxorubicin conjugate (PEG-DXR) o…
We report on the electronic, thermal, and elastic properties of the layered ternary, Ti2SC. Resistivity, Hall effect, and magnetoresistance were measured as a function of temperature between 2 and 300 K and at fields up to 9 T. The Hall coefficient is negative and roughly temperature independent. The transport results…
Abstract Low-temperature FTIR spectroscopy was used to characterize the v(OH) region of kaolin-group minerals including well ordered to poorly ordered kaolins from Georgia, Brazil, and England, along with samples of discrete dickite and nacrite. Low-temperature FTIR spectra were useful in resolving dickite- and nacrit…
Pure and titania modified WO3 films are prepared using pulsed laser ablation technique in an oxygen ambient of 0.12mbar at a substrate temperature of 873K. Titania incorporation effects on the microstructure, optical, and electrical properties on the tungsten oxide films are systematically investigated using technique…
Structural and electronic characteristics of KY(WO4)2 (KYW) (010) crystal surfaces have been studied using reflection high-energy electron diffraction (RHEED) and x-ray photoelectron spectroscopy (XPS). The results indicate that the crystal structure and chemical composition of the mechanically polished pristine surfa…
The paper reports on a scanning tunneling microscopy (STM) study and computer simulation with an N-body interatomic interaction potential of a graphite monolayer (i.e., graphene) on the Ni(111), (110), (755), and (771) single-crystal surfaces. Unlike the case of graphene on Ni(111), which forms a solid single-crystal…
Ferroelectric nanodomains were created in BaTiO(3) thin films by applying a voltage to a sharp conducting tip of a scanning force microscope (SFM). The films were epitaxially grown on SrRuO(3)-covered (001)-oriented SrTiO(3) substrates by a high-pressure sputtering. They appeared to be single-crystalline with the (001…
Nanodiamonds that were prepared by high pressure/high temperature were functionalized with biomolecules for biological applications. Nanodiamonds (NDs, < or =35 nm) that were coated by silanization or with polyelectrolyte layers were grafted with a fluorescent thiolated peptide via a maleimido function; this led to an…
The selective oxidation of methanol to formaldehyde occurring on titania-supported vanadate species has been analyzed theoretically with the aim of understanding why the activity of VO x /TiO 2 is ∼10 3 faster than that of VO x /SiO 2 . The active site was represented by a [(O) 3 V═O] group located at the corner of a…
The byssus of marine mussels has attracted attention as a paradigm of strong and versatile underwater adhesion. As the first of the 3,4-dihydroxyphenylalanine (Dopa)-containing byssal precursors to be purified, Mytilus edulis foot protein-1 (mefp-1) has been much investigated with respect to its molecular structure, p…
Nanostructuring technology has been proven to create unique biological properties in various biomaterials. Here we present a discovered phenomenon of titanium nano-nodular self-assembly that occurs during physical vapor depositions of titanium (Ti) onto specifically conditioned micro-textured titanium surfaces, and te…
Optimized lightweight, compact and high temperature sustaining shielding materials for neutron and gamma radiation were developed by genetic algorithms (GA) combined with the Monte Carlo N-Particle (MCNP) code. A series of samples were designed according to the method. Deep penetration tests by the MCNP code were comp…
This personal account describes how methodology for the synthesis of meso-substituted corroles reached the mature state within just a few years. Both latest developments and many dead-end attempts are described. The comprehensive comparison of conditions of the reaction of aldehydes with dipyrromethanes leading to tra…
Nanotechnology is an emerging technology seeking to exploit distinct technological advances controlling the structure of materials at a reduced dimensional scale approaching individual molecules and their aggregates or supramolecular structures. The manipulation and utilization of materials at nanoscale are expected t…
The MraY transferase is an integral membrane protein that catalyzes an essential step of peptidoglycan biosynthesis, namely the transfer of the phospho-N-acetylmuramoyl-pentapeptide motif onto the undecaprenyl phosphate carrier lipid. It belongs to a large superfamily of eukaryotic and prokaryotic prenyl sugar transfe…
To realize a magnetoelectric heterostructure with desired ferroelectric and magnetic properties, a heterostructure consisting of BiFeO3 (BFO)/CoFe2O4 (CFO) layers has been grown on SrRuO3 buffered Pt/TiO2/SiO2/Si substrate by rf sputtering. X-ray diffraction shows that the BFO and CFO phases have been successfully ret…
