Interfacial electron transfer (ET) in TiO₂-based systems is important in artificial solar energy harvesting systems, catalysis, and in advanced oxidative waste water treatment. The fundamental importance of ET processes and impending applications make the study of interfacial ET a promising research area. Photoexcitat…
By means of ionic implantation the samples were synthesized on the basis of metallic foil (steel of brand of 12Х18Н10Т) with thickness a 0,1 mm. One of them additionally was impregnated with a palladium. Comparison of general coefficients of heat emission from the got standards and NiCr spiral at the expense of air 60…
In this paper, a two-dimensional core-shell nanowire made of a dielectric core and metallic cladding is proposed for exciting the magnetic resonance on an isolated nanostructure. The key idea is to remove a small portion of the metallic cladding on the nanowire so that the incident magnetic field can be localized in t…
An iterative method for phase retrieval for strong phase objects in the form of a complex wave function is proposed. The method utilizes three or more phase contrast images taken with plural Hilbert phase plates, and reconstructs the complex wave function by iterative numerical calculations. The method works even if t…
Background The ATP-binding cassette (ABC) transporters breast cancer resistance protein (BCRP) and P-glycoprotein (P-gp) are expressed in the blood-brain barrier (BBB), where they impede brain uptake of their substrates by active efflux transport. BCRP has recently been shown to be the quantitatively most important AB…
The global problems relevant to the environment and energy are attracting attention, so that it is considered that the construction of efficient light-energy conversion devices serves as an important subject of the scientific research. Thus far, the interaction between photons and molecules has not received much atten…
Neues Werkzeug zur Peptidstrukturbestimmung: Die Aminosäure 4-(3,3,5,5-Tetramethyl-2,6-dioxo-4-oxylpiperazin-1-yl)-L-phenylglycin (TOPP) mit einer starren Nitroxidgruppe als Spinmarkierung wurde für EPR-spektroskopische Abstandsmessungen in Peptiden entwickelt. EPR-Messungen bestätigen eine definierte Orientierung des…

Nanoparticles have been doped or functionalized with photochromic molecules for a variety of applications that take advantage of the photoinduced changes in molecular properties that accompany a photochromic transformation. Many photochromic nanoparticles are designed to be fluorescent and to undergo reversible change…

Layer structures around an edge dislocation in a smectic phase under shear are studied with both phase field and order parameter models. It is shown that, contrast to a crystal solid, the conventional picture of the Peach–Koehler force experienced by dislocations when the sample is under a shear stress cannot be readi…
This contribution focuses on a survey of the most important advances in the photophysics of organic conjugated oligomers and polymers which occurred in the past year. We will focus particularly on the different contributions to the decay mechanisms, the relevance of the triplet state characterization and some relevant…
Nanoparticles (NPs) exhibit interesting size-dependent electrical, optical, magnetic, and chemical properties that cannot be observed in their bulk counterparts. The synthesis of NPs (i.e., crystalline particles ranging in size from 1 to 100 nm) has been intensely studied in the past decades. Magnetic nanoparticles (M…
The skutterudite PrRu 4 P 12 exhibits a metal–insulator transition at 63 K which is known as a consequence of an unconventional charge order (CO) transition. In this paper, the origin of a giant magneto-transport (GMT) in the CO phase at low temperatures is studied theoretically. First, we introduce an effective low-e…
This report summarises the literature reported in 2010 on the photophysical properties of metal complexes and their polynuclear supramolecular assemblies. The transition metal species considered here have been largely studied because of their optical properties, in particular luminescence. The complexes are from the f…
This study describes a successful approach for the synthesis of dipyrromethanes using iodine as a catalyst on grinding. This protocol does not require any solvent and carried out at lowest pyrrole/aldehyde ratio which makes this method economically and environmentally attractive. This protocol affords the products imm…
A size controllable graphene micro/nanogap fabrication method using micro/nanowire as mask is presented. The gap dimension can be adjusted by the diameter of the mask wire. As a typical application, copper phthalocyanine (CuPc) film organic field-effect transistors (OFETs) were fabricated with the graphene micro/nanog…
A recently proposed non hard sphere (HS) coupling parameter expansion (CPE) thermodynamic perturbation theory (TPT) is evaluated for its performance over a wide range of temperatures, particularly in tackling a so-called low temperature problem, i.e. the traditional high temperature series expansion TPT performance be…
Permittivity and electromagnetic losses of sapphire, ruby, and irradiated ruby samples were examined at frequencies of 30–40 GHz and temperatures of 4–300 K employing the whispering gallery mode technique. At room temperature, the dielectric properties of the sapphire, ruby, and irradiated ruby samples were similar. S…
We report first-principles density functional theory calculations of the electronic structure of ZnSe1−xSx ternary quantum dots (TQDs) and the impact of composition and compositional distribution on the electron density distribution, electronic density of states, and band gap. We find that the band gaps for ZnSe/ZnS c…
