This review surveys recent advances in the synthesis of oxide materials, primarily as supported thin films but also in other forms such as free-standing films, mesoporous solids, and nanostructured fibers, from liquid (primarily aqueous) solutions. New studies using chemical bath deposition (CBD), liquid phase deposit…
We present a coarse-graining procedure for homopolymer melts mapping intra- as well as inter-molecular interactions from a chemically realistic united atom description to a bead-spring type molecular model. On the coarse-grained level the repeat units interact through bond-length and bond angle potentials and a non-bo…
This paper describes a method for cable system condition monitoring, developed initially at the IFE Halden Reactor Project and then further developed at Wirescan AS, which is based on transmission line theory and resonance analysis. This method resulted in the development of a system called LIRA (LIne Resonance Analys…
An electric fatigue test system was developed for evaluating the reliability of piezoelectric actuators with a mechanical loading capability. Fatigue responses of a lead zirconate titanate (PZT) multilayer actuator with a platethrough electrode configuration were studied under an electric field (1.7 times that of the…
A combination of structural and electrical characterization techniques was applied to polymer Ta capacitors with in situ and prepolymerized poly(3,4-ethylenedioxythiophene) (PEDOT) cathodes with a broad range of Ta 2 O 5 dielectric thicknesses. The in situ PEDOT was produced by polymerizing the EDOT monomer using an o…
We study the superstructures and phases formed by linear rigid coarse-grained particles using molecular dynamics simulations in the isothermal–isobaric ensemble (NPT). Chiral barrel-shaped and chiral column superstructures self-assemble from these building blocks at low pressures and Monte Carlo parallel tempering and…
The influence of the local stress state and crystallinity of graphite on the graphite-diamond transformation process was investigated using a laser-heated diamond anvil cell and two types of graphite samples with contrasting crystalline characteristics. The samples recovered from the experiments using highly oriented…
Oxidative cleavage of carbon-carbon double bonds of cyclic olefins with hydrogen peroxide in the presence of heteropolyacids has been investigated as a clean and environmentally friendly preparation of polycarboxylic acids. In the presence of 12-tungstophospholic acid (H(3)PW(12)O(40)), adipic acid was obtained in 95%…
An unprecedented extended architecture, Na(8)H(2)L(H(2)enMe)(4){Mn(H(2)O)(2)[(W(4)Mn(4)O(12))(P(2)W(14)O(54))(2)]}.17H(2)O, (, Na(8)H(2)L(H(2)enMe)(4)[].17H(2)O, enMe = 1,2-diaminopropane) constructed from double-Dawson type polyoxoanions (DDTP) has been successfully synthesized under hydrothermal conditions. Single-c…
First-principles calculations of the thermodynamic properties of Ti2AlC and Ti2SC were carried out. The temperature dependence of bulk modulus, the pressure dependence of normalized volume V⁄V0, thermal expansion coefficient, specific heats, and Debye temperature were successfully obtained through the quasi-harmonic D…
Triangular trinuclear Co(iii), Rh(iii), and Ir(iii) dithiolene complexes, [[M(3)(eta(5)-C(5)Me(5))(3)(S(6)C(6))] (M = Co, Rh, Ir), which have not been obtained by the trimerization of mononuclear complexes, were synthesized via a new synthetic route, that is, the reaction of benzenehexathiol and [(eta(5)-C(5)Me(5))Co(…
Porous tungsten oxide films of nanocrystalline tungsten oxide embedded in an amorphous tungsten oxide matrix have been synthesized via poly(ethylene glycol) (PEG)-template sol-gel technique with peroxopolytungstic acid precursor. The effects of PEG addition on the microstructure and electrochromic performance of the t…
The adsorption and self-assembly of alpha,omega-aliphatic diamines on silver nanoparticles is studied in this work by surface-enhanced Raman scattering (SERS) spectroscopy and plasmon resonance. These bifunctional diamines can act as linkers of metal nanoparticles (NPs) inducing the formation of hot spots (HS), i.e. i…
A general concept for oxidation-state control of nanoparticles synthesized via chemical reduction has been developed. By comparing kinetically determined mixed potential measured in reaction solution and thermodynamically drawn potential diagrams, e.g., potential–pH diagram, it is possible to know “what chemical speci…
The poor performance of natural fibres as composite reinforcements where the focus on chemical aspects has not yet delivered the "holy grail" of glass fibre replacement in volume applications is discussed. An explanation is proposed based on the anisotropic structure of these fibres and its influence the composite int…

Dynamical simulations of polaron transport in conjugated polymers in the presence of an external time-dependent electric field have been performed within a combined extended Hubbard model (EHM) and Su-Schrieffer-Heeger (SSH) model. Nearly all relevant electron-phonon and electron-electron interactions are fully taken…
In this paper we develop an analytical framework for the study of electrochemical impedance of mixed ionic and electronic conductors (MIEC). The framework is based on non-equilibrium thermodynamics and it features the coupling of electrochemical reactions, surface transport and bulk transport processes. We utilize thi…

In many cases, to obtain the required extent of protection against electromagnetic radiation (EMR) emitted by operating electrical and electronic devices, it is not enough to use only shielding materials that non-transmit the radiation as a results of its reflection, but it is in dispensable to use shields (materials)…
