By means of density functional theory, a hexanuclear sandwich complex [18]annulene-Li6-[18]annulene which consists of a central Li6 hexagon ring and large face-capping ligands, [18]annulene, is designed and investigated. The large interaction energy and HOMO-LUMO gap suggest that this novel charge-separated complex is…
Abstract An alternative way to process data from polarization measurements for fuel cell model validation is proposed. The method is based on re‐ and subsampling of I–V data, with which repetitive estimations are obtained for the model parameters. This way statistics such as standard deviations and correlations betwee…
Abstract A mixture of post-commercial polyolefin waste (PE/PP/PS) was pyrolyzed over various micro- and mesoporous catalysts using a fluidized-bed reactor operating isothermally at ambient pressure. The yield of volatile hydrocarbons with zeolitic nano-catalysts (n-ZSM-5 > n-MOR > n-USY) were higher than with non-zeol…
Abstract Early‐stage tensile stress evolution in α‐Al2O3 scales during oxidation of FeCrAlY at 1000, 1050, 1100, and 1200 °C was monitored in situ by use of synchrotron radiation. Tensile stress development as a function of oxidation temperature indicated a dynamic interplay between stress generation and relaxation. A…
The poor outcome of primary malignant brain tumors is predominantly due to local invasion and recurrence. Multifunctional nanoparticles harbouring various functions including targeting, imaging and treatment have been intensively studied aiming to overcome limitations associated with conventional cancer diagnosis and…
Reentrant behavior is known to exist and magnetic-field-induced superconductivity has been predicted in superconductors with Kondo impurities. We present a simple framework for understanding these phenomena and generalize it to explain the long-standing puzzle of paramagnetic reentrance in thick proximity systems as b…
We study the electronic structure and magnetic interactions in methylamine-intercalated orthorhombic alkali-doped fullerene $({\mathrm{CH}}_{3}{\mathrm{NH}}_{2}){\mathrm{K}}_{3}{\mathrm{C}}_{60}$ within the density functional theory. As in the simpler ammonia intercalated compound $({\mathrm{NH}}_{3}){\mathrm{K}}_{3}{…
Abstract Optoelectronic properties and low temperature thermoelectric effects were studied on polycrystalline thin films of ternary chalcopyrite ordered vacancy compound (OVC) n‐CuIn3Se5. The thin films prepared by three source vacuum co‐evaporation method were preliminarily characterized structurally, morphologically…
The article by Dr Thomas Julius Borody in this issue is a review of a topic that has long been debated: the role of Mycobacterium avium subspecies paratuberculosis (MAP) in the etiopathogenesis of Crohn’s disease.1 Dr Borody addresses the key elements of the MAP argument in a point-by-point manner. However, the debate…
Endogenous galactitol-1-phosphate 5-dehydrogenase (GPDH) (EC 1.1.1.251) from Escherichia coli spontaneously interacts with Ni(2+)-NTA matrices becoming a potential contaminant for recombinant, target His-tagged proteins. Purified recombinant, untagged GPDH (rGPDH) converted galactitol into tagatose, and d-tagatose-6-p…
The reaction of M(SiH 3 ) 3 (M = P, As) with Al atoms from a Knudsen cell has recently led to an entirely new approach to the synthesis of (III–V)–(IV) alloys on Si substrates using gas-source molecular beam epitaxy. The main feature of these new materials is the presence of isolated “donor–acceptor” pairs within full…
PURPOSE: Long-term stable cationic solid lipid nanoparticles (cSLNs) were formulated to transfer SMAD3 antisense oligonucleotides (ASOs) into the cells to enhance the intracellular activity of the ASOs. The SMAD3 ASOs were designed to block the inflammatory processes linked to TGFβ/SMAD3 pathway. METHODS: The cSLN for…
Abstract Metal‐doped mesoporous composites were synthesised by using a facile one‐pot sol–gel approach. Special multifunctional surfactants were designed and used simultaneously as structure‐directing agents, N‐doped carbon source and metal dopant. This versatile profile of properties is obtained by combining complex…
The effect of oxygen adsorption and desorption on the photoconducting gain, spectral dependence of quantum efficiency and optical switching was studied in CdS nanorods with diameters of 20, 50 and 100 nm. These were found to have an increasing degree of crystallinity and consequently a decreasing overall density of de…
This study investigated the effect on the curing behavior, activation energy (E a) of the curing reaction, crystalline structure, crosslinking, and free formaldehyde content of the addition of the following scavengers in urea-formaldehyde (UF) resins: medium density fiber board flour, rice husk flour, silica powder, a…
α-Acetal, ω-alkyne poly(ethylene oxide) was synthesized as building block of glycoconjugated poly(ε-caprolactone)-graft-poly(ethylene oxide) (PCL-g-PEO) copolymers. The alkyne group is indeed instrumental for the PEGylation of a poly(α-azido-ε-caprolactone-co-ε-caprolactone) copolymer by the Huisgen's 1,3 dipolar cycl…
Microwave-assisted magnetization reversals of exchange-coupled composite nanopillars were studied by micromagnetic simulation. Magnetization reversal occurred in one or two frequency regions associated with magnetic resonance arising from the soft magnetic section. Significant reductions in ac field strength and frequ…
Multiferroic single-domain nanomagnetics is a promising emerging nanotechnology poised to usher in ultralow energy nanomagnetic nonvolatile logic circuits in numerous medical applications, such as implants and prosthesis, where battery longevity is paramount. This paper evaluates the fundamental mode of signal propaga…
Analytical solution of plane wave scattering by a circular PEMC (Perfect Electromagnetic Conductor) cylinder coated with anisotropic media was presented in this article. When referred to principal axes (ρ, ϕ,z) in the anisotropic region, both permittivity and permeability tensors were biaxial and diagonal; so, the rad…
Abstract Au nanoparticle chains embedded in helical Al2O3 nanotubes (“nanopeapods”) are synthesized by annealing carbon nanocoils coated with Au by sputtering and Al2O3 by atomic layer deposition. Regular spacing between nanoparticles with a sharp size distribution is achieved by fragmentation of the Au coating in agr…
