In low-energy electron microscopy (LEEM) we commonly encounter images which, beside amplitude contrast, also show signatures of phase contrast. The images are usually interpreted by following the evolution of the contrast during the experiment, and assigning gray levels to morphological changes. Through reconstruction…
Abstract The oxidation of CO is the archetypal heterogeneous catalytic reaction and plays a central role in the advancement of fundamental studies, the control of automobile emissions, and industrial oxidation reactions. Copper‐based catalysts were the first catalysts that were reported to enable the oxidation of CO a…
Abstract Soluble π-conjugated polymer derived from a renewable monomer, 3-amino-4-hydroxybenzoic acid (3,4-AHBA), was synthesized by an electropolymerization. The polymer has higher solubility in common solvents, compared to polyaniline, due to the polar side groups such as carboxyl and hydroxyl. The polymer showed va…
This work presents a study of structural and thermoelectric properties of Mg 2 Si coatings deposited on heavily doped p‐ and n‐type Si substrates, at 650 °C. The as‐grown layers were smooth and uniform in thickness without any texture, voids, or large density of cracks. The sign of Seebeck coefficient in deposited lay…
[La0.7Ca0.3MnO3(2.6 nm)/SrTiO3(6.3 nm)]15 superlattices (SLs) have been simultaneously grown by Pulsed Laser Deposition (PLD) on different oxide substrates in an attempt to obtain different residual strain states. The substrates are (100)-oriented SrTiO3 (STO), LaAlO3 (LAO), and piezoelectric 0.72Pb (Mg1.3 Nb2.3)3-0.2…
We have developed a new method to analyze the amount and distribution of diffraction light for a diffraction grating lens. We have found that diffraction light includes each-order diffraction light and striped diffraction light. In this paper, we describe characteristics of striped diffraction light and suggest a way…
Abstract Charge‐transfer salts composed of biferrocene derivatives and X n –TCNQ (X = F, Cl; n = 1, 2; TCNQ = tetracyanoquinodimethane) were prepared and crystallographically characterized. All nine salts exhibited a 1:2 donor/acceptor (D/A) ratio consisting of mixed‐valence biferrocenium cations and anions with accep…
A novel superlattice structure based on epitaxial nanoscale layers of NbO x and Nb-doped SrTiO 3 is fabricated using a layer-by-layer approach on lattice matched LAO substrates. The absolute Seebeck coefficient and electrical conductivity of the [(NbO x ) a /(Nb-doped SrTiO 3 ) b ] 20 superlattices (SLs) were found to…
We have grown carbon nanotubes using Fe and Ni catalyst films deposited by atomic layer deposition. Both metals lead to catalytically active nanoparticles for growing vertically aligned nanotube forests or carbon fibres, depending on the growth conditions and whether the substrate is alumina or silica. The resulting n…
The skin, which acts as a protector of the body from potentially harmful external environment is a multi-layered tissue that exhibits complex mechanical behaviour. The aim of this paper is to review available studies of human skin using experimental and numerical methods in determining the mechanical properties of ski…
A new type of hybrid photosensitizer (Po–C30B) was obtained by efficient adsorption of a 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin (Po) by Cloisite 30B (C30B)—a monotallow bis(hydroxyethyl)ammonium-modified montmorillonite clay—from acidic solution in methanol. Structural and spectroscopic properties of Po-nanocla…

All measured lines were indexed, a…
Electronic band structures and phonon bands of bulk, bilayer and monolayer MoS 2 are studied by DFT and GW methods and discussed in the framework of applicability of the 2D model for layered systems. The MoS 2 monolayer is found to be a direct gap semiconductor with the top of the valence band and the bottom of the co…
A facile and universal method is presented for the preparation of polymer brushes on amorphous TiO2 film. Homogeneous and stable poly(methyl methacrylate), polystyrene, poly(4-vinylpyridine), and poly(N-vinyl imidazole) (PNVI) brushes up to 550 nm are directly created onto TiO2 via UV-induced photopolymerization of co…
The physicochemical properties of coix seed oil (CSO) liposomes prepared by five different methods were evaluated for morphology, encapsulating efficiency, particle size, storage stability, and in vitro release. The different preparation methods resulted in several types of vesicles with different properties. The type…
The thermoelectric properties of gate-all-around silicon nanowires (Si NWs) are calculated to determine the potential for significant power factor enhancement. The Boltzmann transport equation and relaxation time approximation are employed to develop an electron transport model used to determine the field-effect mobil…
