Octachloro zinc phthalocyanine networks on Ag(111) have been used as host structures for the insertion of penta- tert -butylcorannulene (PTBC) molecules. At ambient temperature, the resulting coassemblies generally present lines or chessboard structures, depending on the PTBC coverage. In this paper, it is shown that…
The formation of iron aluminide coating on an Al surface by mechanical alloying with Al–Fe powder of various compositions was investigated. When the amount of Fe powder in the starting powder is >50 at.‐%, an FeAl containing coating layer is formed. As the mass ratio of the balls and substrate to the powder in the pot…
Continuous fibre reinforced composites are now firmly established engineering materials for the manufacture of components in the automotive and aerospace industries. In this respect, composite fabrics provide flexibility in the design manufacture. The ability to define the ply shapes and material orientation has allow…
Water dynamics and compartmentation in glutaraldehyde cross-linked bovine serum albumin nanoparticles have been investigated by an integrated nuclear magnetic resonance (NMR) protocol based on water relaxation times and self-diffusion coefficients measurements. Multi-exponentially of water relaxation curves has been a…
Cortactin is a ubiquitous actin-binding protein that regulates various aspects of cell dynamics and is implicated in the pathogenesis of human neoplasia. The sequence of cortactin contains a number of signaling motifs and an SH3 domain at the C-terminus, which mediates the interaction of the protein with several partn…
Circular open-ring resonators (ORR) merit special attention in many applications. They form the backbone of metamaterials. Therefore, a simple and accurateLCmodel is required to allow the behavior of the structure to be analyzed from the geometric parameters. In this paper, we propose an analytical model to compute th…
Tuning of the resonant wavelength of a single hole defect cavity in planar photonic crystals was demonstrated using transmission spectroscopy. Local post-production processing of single holes in a planar photonic crystal is carried out after selectively opening a masking layer by focused ion beam milling. The resonanc…
We have observed the formation of protein–nanoparticle complexes at the air–water interfaces from three different methods of presenting the nanoparticles to proteins. The structures formed are remarkably reproducible for the three formation mechanisms. The methods of X-ray and neutron reflectivity (with isotopic contr…
Substitution of Cu for Ni in the Kondo lattice system ${\text{CeNi}}_{2}{\text{Al}}_{3}$ results in a simultaneous optimization of the three interdependent thermoelectric parameters: thermoelectric power, electrical, and thermal conductivities, where the electronic change in conduction band induced by the extra electr…
The introduction of nanometric contrast agents to optical imaging is helpful for the understanding of some biological processes at the molecular level, as well as the development of diagnostic tools and therapies. Optical imaging agents such as gold nanorods (GNRs), quantum dots (QDs), and organically modified silica…
The local critical current density in thin-film hybrid structures of high-temperature superconducting ${\text{YBa}}_{2}{\text{Cu}}_{3}{\text{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ and ferromagnetic ${\text{La}}_{2/3}{\text{Ca}}_{1/3}{\text{MnO}}_{3}$ (LCMO) is measured with high accuracy using a quantitative magnet…
Aggregatibacter actinomycetemcomitans is a Gram-negative opportunistic pathogen and the proposed causative agent of localized aggressive periodontitis. A. actinomycetemcomitans is found exclusively in the mammalian oral cavity in the space between the gums and the teeth known as the gingival crevice. Many bacterial sp…
Wavelength-dependent measurements of the quasi-Fermi level of electrons by the suspension photovoltage method allows locating intra-bandgap states involved in interfacial electron transfer. Employing in these experiments reducing agents with current amplification properties may lead to false results due to the strongl…
AIMS: A problem in generating artificial tissues is supplying nutrients to cells within 3D constructs. The use of a decellularized biological vascularized matrix with preserved pedicles (BioVaM), as a scaffold, appears to aid the generation of perfusable tissue constructs in vitro. To prevent vessel occlusion upon imp…
We combine the most efficient (chemical) approach toward three-dimensional photonic crystals with the most convenient (physical) technique for creating non-close-packed crystalline structures. Self-assembly of colloidal particles in artificial opals is followed by a carefully tuned plasma etching treatment. By coverin…
The charge-storage characteristics of a metal-oxide-semiconductor (MOS) structure containing size-tunable sub-2 nm Pt nanoparticles (NPs) between Al2O3tunneling and capping oxide layers were studied. Significantly different amounts of memory window were obtained with the different sizes of Pt NP embedded MOS structure…
Optical-quality, melt processable thick films of a conjugated polymer blend containing poly(2-methoxy-5-(2-ethyl-hexyloxy)-(phenylene vinylene)) (MEH-PPV), a C(60) derivative (PCBM) and a plasticizer (1,2-di-iso-octylphthalate) have been developed and their nonlinear absorption and optical limiting properties have bee…
Electrical-transport properties of ferromagnetic GaGdN layers grown by molecular-beam epitaxy on highly resistive 6H-SiC(0001) substrates have been investigated. It is found that doping with low concentrations of Gd increases the resistivity by several orders of magnitude as compared to unintentionally doped GaN. In t…
The photophysical behavior of the trans -4-propoxy 4′-nitrostilbene ( PNS ) as well as its one- and two-photon polymerization properties are reported. A detailed solvatochromic analysis of the steady-state and time-resolved fluorescence indicates that the locally excited state of PNS (LE) undergoes multiple deactivati…
Abstract We investigate adhesion of fetal bovine serum (FBS) on diamond surfaces which have alternating H/O‐terminated surface patterns of 30 µm width prepared by hydrogen and oxygen plasma. The samples are immersed into 15% FBS in McCoy's 5A supporting medium and characterized by in situ atomic force microscopy (AFM)…
