Electrochemical noise measurements were performed to investigate the intrinsically stochastic character of the tribocorrosion process. Unidirectional sliding tests (pin-on-disc) were performed using AISI 304L stainless steel sliding against corundum. Experiments were carried out in Cl − and containing media under open…
Abstract Chain‐growth polycondensation of 3‐(alkylamino)benzoic acid alkyl esters 1 was investigated for obtaining poly( m ‐benzamide)s with defined molecular weights and low polydispersities. Polymerization conditions were first studied to find that ethyl 3‐(octylamino)benzoate ( 1b ) polymerized in a chain polymeriz…
Abstract The use of natural organic fillers in addition to postconsumer recycled polymers is getting a growing interest during the last years; this is due to many advantages they can provide in terms of cost, aesthetic properties, environmental impact. In this work, several types of wood flour (differing each other wi…
Abstract The blends of thermoplastic polyether‐based urethane elastomer (TPEU) and monomer casting polyamide 6 (MCPA6) were prepared using ε‐caprolactam (CL) as a reactive solvent, and CL sodium as a catalyst at various TPEU contents (2.5–15 phr by weight). In situ anionic ring‐opening polymerization and in situ compa…
We consider the nonequilibrium thermodynamics of glasses from various perspectives. For the commonly used equilibriumlike approach based on Gibbs' fundamental form with an additional pair of conjugate variables, we discuss possible choices of the independent out-of-equilibrium variable and we illustrate some implicati…
Molecular-scale understanding and manipulation of the wetting behavior of water on solids remains a fundamental challenge. Using diamond as a model system, we show that the naturally hydrophobic behavior of a hydrogen-terminated C(111) surface can be manipulated by replacing the H termination with a monolayer of adsor…
We have investigated the effective magnetic anisotropy in CVD-grown epitaxial $\mathrm{Cr}{\mathrm{O}}_{2}$ thin films and ${\mathrm{Cr}}_{2}{\mathrm{O}}_{3}∕\mathrm{Cr}{\mathrm{O}}_{2}$ bilayers using resonant radio-frequency transverse susceptibility (TS). While $\mathrm{Cr}{\mathrm{O}}_{2}$ is a highly spin polariz…
The title compound, Ba4Ga2B8O18Cl2.NaCl, is found to crystallize in a polar space group P4(2)nm with cell dimensions of a = 12.1134(2) A and c = 6.8456(1) A. The basic building blocks of the structure are the B4O9 groups, which are interconnected by the GaO4 tetrahedron to form a three-dimensional net with Ba2+ ion-,…
A detailed study of the formation of neutral oxygen vacancies in monoclinic tungsten oxide (WO 3 ) is performed within the framework of the self-consistent first-principles SIESTA method. This work reveals that the neutral oxygen vacancies are anisotropic with a strong correlation to the structural anisotropy of the W…
Abstract The synthesis of the new ligand, BEDT‐TTF‐bipy [4,5‐ethylenedithio‐4′,5′‐(4′‐methyl‐2,2′‐dipyrid‐4‐ylethylenedithio)tetrathiafulvalene] is reported. The first Fe II coordination complex, namely [Fe(NCS) 2 (BEDT‐TTF‐bipy) 2 ] · CHCl 3 , with this redox‐active ligand is obtained. Magnetic measurements and Mössb…
OBJECTIVE: The objective of this study is to delineate the molecular mechanisms responsible for Staphylococcus aureus-platelet adhesion as a function of physiologically relevant wall shear stresses. METHODS AND RESULTS: A parallel plate flow chamber was used to quantify adhesion of wild-type, Spa-, ClfA- and SdrCDE- s…
The morphological changes of isotactic polypropylene (iPP) subjected to varying shear strains have been investigated by the equal channel angular extrusion (ECAE) process. Morphological measurements were made by wide- and small-angle X-ray scattering (WAXS and SAXS) using synchrotron radiation, differential scanning c…
Abstract Exfoliated polypropylene (PP)/layered double hydroxide (LDH) nanocomposites have been successfully synthesized via melt‐intercalation. Their structure, thermal properties, and photo‐oxidative behavior have been characterized by X‐ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric…
A new strategy to grow thermoelectric nanostructures on a wide variety of substrates is introduced. The synthesis involves the reduction of a selenium precursor to promote nucleation with bismuth ions to produce Bi2Se3 nanostructured films (see picture, scale bar 10 μm) under thermodynamic control. Thermoelectric tran…
We analyse the symmetries and the self-consistent perturbative approaches of dynamical field theories for glass-forming liquids. In particular, we focus on the time-reversal symmetry, which is crucial to obtain fluctuation–dissipation relations (FDRs). Previous field theoretical treatment violated this symmetry, where…
The local Fe structure and corresponding ferromagnetism are different for various concentrations of Fe-doped ZnO (Zn1?xFexO, x = 0?0.07) films, which are prepared on LiNbO3(104) substrates by reactive magnetron sputtering. X-ray photoelectron spectroscopy and x-ray absorption near-edge structure (XANES) reveal that, w…
A theoretical study was performed on a novel class of boron-containing molecules (various substituted tetraarylazadipyrromethenes), which show in vitro activity for application in photodynamic therapy. Geometric optimisation of the structures for the singlet and triplet electronic states was carried out on compounds i…
In colloidal suspensions, at low volume fraction and temperature, dynamical arrest occurs via the growth of elongated structures that aggregate to form a connected network at gelation. Here we show that, in the region of parameter space where gelation occurs, the stable thermodynamical phase is a crystalline columnar…
The objective of every industrial crystallization process is to create crystals that meet specifications on size, shape, composition, and internal structure. This objective is achieved using a variety of methods and equipment configurations depending on the properties of the chemical system, the end-product specificat…
Soluble, ultra-short (length < 60 nm), carboxylated, single-walled carbon nanotubes (SWNTs) have been prepared by a scalable process. This process, predicated on oleum's (100% H2SO4 with excess SO3) ability to intercalate between individual SWNTs inside SWNT ropes, is a procedure that simultaneously cuts and functiona…
