An intrinsic shortcoming of self-organizing materials is their susceptibility to structural changes by mechanical forces and exposure to chemicals and radiation. Cross-linking of the molecules in the desired supramolecular structure is a generally applicable pathway to structurally more stable materials but is difficu…
We investigated optical properties of three‐dimensional (3D) assemblies of Au nanoparticles (NPs), which were fabricated by dewetting of thin Au layers on anodic aluminum oxides (AAO). The NP assembly had hexagonal array of repeated multiparticle structures, which consisted of six trimers on the AAO surface and one la…
The growth conditions required to obtain high-quality layered-perovskite Nd2Ti2O7 thin films with a monoclinic structure on both (100)- and (110)-oriented SrTiO3 substrates by pulsed laser deposition are investigated. To synthesize the expected ferroelectric crystalline phase (and optimize the crystallization), two ma…
This paper reports on fabrication of water-compatible palladium nanoparticle (PdNP) catalysts supported on microporous polymers, which show high activity and extremely low Pd leaching behaviour in the usage for carbon cross-coupling reactions. The supported PdNP catalysts were fabricated by utilizing the polymerizatio…
The corrosion inhibition effect of Rabeprazole sulfide (RS) on mild steel in 1 M hydrochloric acid (HCl) was investigated using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and chronoamperometric measurements. Protection efficiency of RS increases with the concentration and…
Mixing [M(Et2dazdt)2](BF4)2 [M = Ni(II), Pd(II), Pt(II); Et2dazdt = N,N'-diethyl-perhydrodiazepine-2,3-dithione] with (Bu4N)2[M(mnt)2] (mnt = maleonitrile-2,3-dithiolate) in CH3CN produces the known mixed ligand dithiolene complex [Ni(Et2dazdt)(mnt)] in the nickel case and ion-pair salts [M(Et2dazdt)2][M(mnt)2] in the…
State of the art molecule-based conductors that have been isolated as nanoparticles are reviewed. Research efforts in this field is justified by their insolubility and low vapour pressure, making their integration into electronic devices difficult. Their availability as nanoparticles would allow researchers to study t…
Direct bandgap semiconductors, such as In2O3, Cu2O, and SnO2, have enormous applications in photochemistry, photovoltaics, and optoelectronics. Due to the same parity of conduction and valence bands, the dipole transition is silent in these direct bandgap semiconductors. The low band-to-band transition efficiency prev…
Al-doped ZnO nanoparticles are synthesized by means of a heating up solution based thermal decomposition method. The synthesis involves a reaction of zinc acetylacetonate hydrate, aluminium acetylacetonate and 1,2-hexadecanediol in the presence of oleic acid and oleyl amine. A proposed reaction mechanism from reagents…
Electrodeposition inside an insulated nanoporous template using Room Temperature Ionic Liquids (RTILs) has recently been demonstrated as a promising alternative technique for synthesizing silicon nanowires due to low cost ambient growth conditions. An improvement of the method is shown here to produce Si nanotubes. A…
We propose the first, to our knowledge, coarse-grained modeling strategy for peptides where the effect of changes of the pH can be efficiently described. The idea is based on modeling the effects of the pH value on the main driving interactions. We use reference data from atomistic simulations and experimental databas…
The mechanism of plasmon-induced charge separation of gold nanoparticles (Au NPs) on TiO2 was investigated with the help of anionic ligands. Au NPs are oxidized in the presence of KX (X = SCN, Br or Cl), chiefly via direct oxidation to [AuX4](-). The reactivity of Au NPs depends on the solution pH, the type of anion l…
Although Eucalyptus pulp has been widely used in the paper industry, there is limited information concerning its use as reinforcement in fibre-cement composites. The objective of this study was to evaluate effects of mechanical treatment (refining) of the Eucalyptus pulp on fibre properties as well as performance and…
Ytterbium oxide (Yb 2 O 3 ) nanocrystals with different Eu 3+ (1%, 2%, 5%, and 10%) doped concentrations were synthesized by a facile hydrothermal method, subsequently by calcination at 700°C. The crystal phase, size, and morphology of prepared samples were characterized by X-ray diffraction (XRD) and transmission ele…
To improve the photocatalytic activity of a coordination polymer in the visible light region, polyaniline (PANI) was loaded onto its surface through a facile in situ chemical oxidation polymerization process. The resulting PANI loaded coordination polymer composite materials with excellent stability exhibit significan…
A novel Pd capillary membrane microreactor for one-step hydroxylation of benzene to phenol was synthesized and investigated to showcase the effectiveness of ‘Niwa concept’. Reaction parameters including H2/O2 ratio and temperature were systematically studied for their effects on benzene conversion and phenol yield. A…
Fischer-Tropsch (FT) synthesis is an important process to manufacture hydrocarbons and oxygenated hydrocarbons from mixtures of carbon monoxide and hydrogen (syngas). The catalysis process occurs on, for example, cobalt metal surfaces at elevated temperatures and pressures. A fundamental understanding of the reduction…
Targeted delivery of therapeutic agents to tumor sites increases efficacy and limits off-target toxicity. Nanoparticles are an emerging class of targeted drug delivery systems. Commonly, nanoparticles are coated with poly(ethylene glycol) (PEG) to reduce off-target uptake by cells of the mononuclear phagocyte system (…
We derive continuum limits of atomistic models in the realm of nonlinear elasticity theory rigorously as the interatomic distances tend to zero. In particular we obtain an integral functional acting on the deformation gradient in the continuum theory which depends on the underlying atomistic interaction potentials and…
In-situ observations on the dynamic precipitation behavior of secondary carbides in Ti-alloyed High Chromium Cast Iron (HCCI) were performed by using a Confocal Laser Scanning Microscope (CLSM). Moreover, the detailed characterization of the microstructure before and after heat treatment was performed by using scannin…
