We have studied the colour centre production in yttria-stabilized zirconia (ZrO(2):Y(3 +)) by heavy ion irradiation in the GeV range using on-line UV-visible optical absorption spectroscopy. Experiments were performed with 11.4 MeV amu(-1) (127)Xe, (197)Au, (208)Pb and (238)U ion irradiations at 8 K or room temperatur…
Abstract The synthesis and characterization of a new hyperbranched PAE with a flexible structure and terminal hydroxyl groups is reported. The influence of PAE in the anionic curing of DGEBA with 1‐methylimidazole was studied. The curing reaction was investigated by DSC and FT‐IR. The covalent incorporation of the mod…
For the first time, octaglycosylated zinc(II) phthalocyanines in which the sugar part is protected by acetyl groups and the deprotected zinc(II) phthalocyanines were synthesized and characterized. The sugars glucose, galactose, lactose, cellobiose, and maltose are anomerically attached either via oxygen or sulfur to t…
We performed model calculations of Raman responses for multiband two-dimensional superconductors. The multiband effects of screening in the ${A}_{1g}$ symmetry channel were investigated analytically and numerically for a band-structure model mimicking angle-resolved photoemission spectroscopy data on iron-pnictide mat…
Size, composition, and pattern formation are crucial elements in the fabrication of functional multicomponent nanoparticles (NPs). Self-assembly techniques provide relevant control over NP size distribution (down to a few nanometers in diameter), but more importantly, such techniques are amenable for practical applica…
Protein fluorescence and small-angle X-ray scattering (SAXS) have been used to monitor effector affinity and conformational changes previously associated with allosteric regulation in rabbit muscle pyruvate kinase (M(1)-PYK). In the absence of substrate [phosphoenolpyruvate (PEP)], SAXS-monitored conformational change…
We characterize the elastic contribution to the surface free energy of a nematic liquid crystal in the presence of a sawtooth substrate. Our findings are based on numerical minimization of the Landau-de Gennes model and analytical calculations on the Frank-Oseen theory. The nucleation of disclination lines (characteri…
This paper reports two new indium tin oxide (ITO)-based nanostructures, namely ITO@carbon core-shell nanowire and jagged ITO nanowire. The ITO@carbon core-shell nanowires (~50 nm in diameter, 1-5 μm in length,) were prepared by a chemical vapor deposition process from commercial ITO nanoparticles. A carbon overlayer (…
Linear and star-shaped polyglycidols were prepared using ethoxy ethyl glycidyl ether (EEGE) as monomer and 3-phenyl-1-propanol and dipentaerythritol as initiator, respectively. These polymers were treated with 2-chloroethylsulfonyl chloride to form reactive vinyl sulfonate end groups. The high reactivity of the vinyl…
The complex ac admittance of a thin film of carbon nanotube/polymer composites depending on both the concentration and the alignment of nanotubes has been studied. The complex ac admittance and the current intensity distribution is numerically calculated using a transfer matrix method, where the discretized mesh model…
The structural evolution of a colloidal crystal fiber during heating and annealing was followed by in situ synchrotron small-angle X-ray scattering. The polymer dispersion (with a particle size of 118 nm) from which the fibers were formed by directed drying contained emulsifier and salt. A cellular structure formed up…
We present a comprehensive comparison of the infrared charge response of two systems, characteristic of classes of the 122 pnictide $({\text{SrFe}}_{2}{\text{As}}_{2})$ and 11 chalcogenide $({\text{Fe}}_{1.087}\text{Te})$ Fe compounds with magnetically ordered ground states. In the 122 system, the magnetic phase shows…
We study the band and transport features of zigzag graphene nanoribbon with an antidot lattice. It is found that an antidot lattice could turn semi-metal graphene into a semiconductor. The size of the band gap can be tuned by the position of the antidots and the distance D between the two nearest antidots. For a finit…
A parameter study is carried out for an inductively coupled plasma used for the synthesis of carbon nanotubes or carbon nanofibres (CNTs/CNFs), by means of the Hybrid Plasma Equipment Model. The influence of processing parameters including gas ratio for four different gas mixtures typically used for CNT/CNF growth (i.…
Thin films and surface coatings play an important role in basic and applied research. Here we report on a new, versatile, and simple method ("precipitation coating") for the preparation of inorganic films, based on the alternate spraying of complementary inorganic salt solutions against a receiving surface on which th…
In this paper nonlinear behaviour of electrostatically actuated carbon nanotubes (CNTs) is investigated. The model comprises a clamped–clamped CNT suspended over a graphite ground electrode plate from which a potential difference is imposed. The actuation is based on ac and dc applied voltages and it is assumed that t…
Recent developments of new electron exchange and correlation functionals within density-functional theory include a solids-biased modification of the popular Perdew-Burke-Ernzerhof (PBE) functional and is referred to as PBEsol. The latter is claimed to remove a bias toward free-atom energies in the former and is there…
Phase change materials are essential to a number of technologies ranging from optical data storage to energy storage and transport applications. This widespread interest has given rise to a substantial effort to develop bulk phase change materials well suited for desired applications. Here, we suggest a novel and comp…
We report specific-heat measurements of the organic superconductors $\ensuremath{\kappa}\text{\ensuremath{-}}{(\text{ET})}_{2}\text{Cu}{(\text{NCS})}_{2}$ and $\ensuremath{\kappa}\text{\ensuremath{-}}{(\text{ET})}_{2}\text{Cu}[\text{N}{(\text{CN})}_{2}]\text{Br}$. When the magnetic field is rotated in the highly condu…
A novel main-chain azobenzene cyclic polymer, cyclic-PEHPA, has been successfully synthesized by 'click' cyclization of the α-alkyne-ω-azido hetero-difunctional linear precursors (linear-PEHPA), which is synthesized by a step-growth polymerization of the 3'-ethynylphenyl[4-hexyl-(2-azido-2-methyl- propionate) phenyl]…
