Investigating the effects of local scattering mechanisms is of great importance to understand charge transport in semiconductors. This article reports measurements of the hole transport properties of boron-doped (100) single-crystalline chemical vapor deposited diamond. A Time-of-Flight measurement using a 213 nm, pul…
Infrared spectra of hydrogenated diamond nanocrystals of one nanometer length are calculated by ab initio methods. Positions of atoms are optimized via density functional theory at the level of the generalized gradient approximation of Perdew, Burke and Ernzerhof (PBE) using 3-21G basis states. The frequencies in the…
We use multi-photon photoemission electron microscopy (PEEM) to image the enhanced electric fields of silver nanoparticles supported on a silver thin film substrate. Electromagnetic field enhancement is measured by comparing the photoelectron yield of the nanoparticles with respect to the photoelectron yield of the su…
This paper exploits the physical investigation on liquid crystal complexes obtained by self-organisation of p-n-alkyl benzoic acid (nBA) mesogens with non-mesogenic materials heptyl p-hydroxy benzoate (7HB). Intermolecular interactions of the molecules result the hydrogen bond between the proton donor (COOH) of nBA an…

The intercalation process of Li underneath a graphene layer grown on a Cu foil has been studied by means of synchrotron radiation photoemission spectroscopy and X-ray photoelectron spectroscopy. The deposition of Li on the graphene surface at room temperature results in a charge transfer from the adsorbed Li atoms to…
From blinking surface-enhanced Raman scattering (SERS) of anionic thiacyanine adsorbed on single Ag nanoaggregates, the electromagnetic field and the molecular behavior in a nonemissive state were investigated by a truncated power law analysis. The power law that reproduces probability distribution of dark SERS events…
Soluble covalent organic nanoframeworks up to generation 2.5 (G2.5) are synthesized with self-similar H-shaped conformations by using a bottom-up approach including iterative C-H bond functionalization. The electrical characteristics of nanoscale thin-film semiconductors of the conjugation-interrupted frameworks can b…
Background: One of the most important causes of complications and mortality in medical centers are nosocomial infections. Disinfection of hospital surfaces is essential element for ensuring that infectious agents are not transmitted to patients. Alcohol-based and chlorine-based disinfectants have unfavorable propertie…
The electronic band structures and dielectric functions of (1−x)PbSc1/2Ta1/2O3−xPbHfO3 ceramics with different composition have been investigated by variable-temperature spectroscopic ellipsometry. Using the standard critical-point (SCP) model, three typical interband transitions can be observed from the second deriva…
We study graphene nanoribbons and carbon nanotubes containing ordered defect lines built of octagonal rings. We show that octagonal defect lines are a robust source of state localization at the Fermi energy, in some cases leading to spontaneous magnetization. We also prove that the localization at chains of octagons i…
Binderless monoliths of supercapacitor electrodes were prepared by the carbonization (N 2 ) and activation (CO 2 ) of green monoliths (GMs). GMs were made from mixtures of self-adhesive carbon grains (SACG) of fibers from oil palm empty fruit bunches and a combination of 5 & 6% KOH and 0, 5 & 6% carbon nanotubes (CNTs…
Abstract Using first‐principles calculations based on density functional theory (DFT) and nonequilibrium Green's function method, we systematically investigated the electronic and magnetic structures, local structural distortion, and electronic spin transport property of a zigzag silicon carbide nanoribbon (ZSiC NR) c…
The effects of alkyl side chain and spacer lengths and the type of terminal group on the morphology and crystallization of a homologous series of biscarbamates (model compounds for polyurethanes) were investigated. Biscarbamates were synthesized with alkyl side chains of various lengths ranging from C4 to C18 and an a…
The properties of the interface in a phase-separated solution of polymers with different degrees of polymerization and Kuhn segment lengths are calculated. The starting point is the planar interface, the profile of which is calculated in the so-called “blob model”, which incorporates the solvent in an implicit way. Th…
We report on a low-damage method for direct and rapid fabrication of arrays of epitaxial BiFeO3 (BFO) nanoislands. An array of aluminium dots is evaporated through a stencil mask on top of an epitaxial BiFeO3 thin film. Low energy focused ion beam milling of an area several microns wide containing the array-covered fi…
Although bone is a nanocomposite of mineral and collagen, mineral has been the more elusive component of study. A standard for bone mineral is clearly needed. We hypothesized that the most natural, least-processed bone mineral could be retrieved from the most highly mineralized bone. We therefore studied the rostrum o…
Structural and static magnetic properties of a series of ferrites nanoparticles (the size ranges from 7.6 to 13.5 nm) having nominal chemical composition DyxMn0.5Zn0.5Fe2−xO4 (x = 0, 0.02, 0.04, 0.06) have been investigated. The x-ray diffraction analysis clarifies that the samples crystallize in typical cubic spinel…
This article reports on two polylactide composites obtained by melt compounding containing two silver-based biocide montmorillonites. The active clays are differentiated by the biocide agent oxidation state, i.e. in one sample silver is in ionic form and in the other as native nanoparticles. In both cases, composites…
In addition to the primary α-process, some neat glass formers show a well resolved secondary β-process (type-B) or solely an excess wing (type-A). We investigate two binary glass forming systems composed of a type-A and a type-B component. (2)H nuclear magnetic resonance (NMR) spectroscopy is selectively applied to th…
