Immobilization and site isolation of catalytically active precursors onto solid surfaces constitute a typical method for realizing high-performance heterogeneous catalysts. Site isolation sometimes not only significantly improves catalyst stability, but also provides unique activity and selectivity on heterogeneous su…

We consider the $Q$-state Potts model on $\mathbb Z^d$, $Q\ge 3$, $d\ge 2$, with Kac ferromagnetic interactions and scaling parameter $\ga$. We prove the existence of a first order phase transition for large but finite potential ranges. More precisely we prove that for $\ga$ small enough there is a value of the temper…
Ambient-pressure X-ray photoelectron spectroscopy (APXPS) allows the investigation of liquid and solid interfaces with gases at pressures in the Torr range, and is thus an excellent tool to study heterogeneous chemical reactions at surfaces in the environment, as well as in technical applications such as catalysis and…
Bifurcation problems in which periodic boundary conditions or Neumann boundary conditions are imposed often involve partial differential equations that have Euclidean symmetry. As a result the normal form equations for the bifurcation may be constrained by the “hidden” Euclidean symmetry of the equations, even though…
Abstract. We consider (generalized) Kolakoski sequences on an alphabet with two even numbers. They can be related to a primitive substitution rule of constant length ℓ. Using this connection, we prove that they have pure point dynamical and pure point diffractive spectrum, where we make use of the strong interplay bet…
A four dimensional treatment of nonrelativistic space-time gives a natural frame to deal with objective time derivatives. In this framework some well known objective time derivatives of continuum mechanics appear as Lie-derivatives. Their coordinatized forms depends on the tensorial properties of the relevant physical…
Abstract. Despite all the analogies with ”usual random ” models, tight binding operators for quasicrystals exhibit a feature which clearly distinguishes them from the former: the integrated density of states may be discontinuous. This phenomenon is identified as a local effect, due to occurrence of eigenfunctions with…

Abstract: For low density gases the validity of the Boltzmann transport equation is well established. The central object is the one-particle distribution function, f, which in the Boltzmann-Grad limit satisfies the Boltzmann equation. Grad and, much refined, Cercignani argue for the existence of this limit on the basi…

An experimental study of the temperature dependence of photoluminescence time decay in size-controlled silicon nanocrystals in silicon nanocrystal/SiO2 superlattices is reported. The samples were prepared using thermal evaporation and subsequent thermally induced phase separation. The slow (microseconds) decay line sh…
Ferrosoferric oxide (Fe(3)O(4)) magnetic material was first synthesized, and then the in-situ chemical polymerization of pyrrole was carried out on the surface of Fe(3)O(4) by using pyrole and L-tryptophan (L-Trp) as the functional monomer and templates, respectively. As a result, molecularly imprinted polypyrrole/Fe(…
In the hot rolling process, rolls with grooves are used for the production of various simple and complex profiles. Main factors influencing the fatigue life of these rolls result from the technological process of the rolling. Rolling speed is an important parameter of technological process which has great influence on…
Mechanical properties and deformation mechanism of polypropylene (PP) filled with different weight percentage of ethylene–octene copolymer (EOC) and fibrillar silicate attapulgite (ATP) clay were investigated under uniaxial cyclic loading at constant crosshead speed to evaluate plasticity/damage coupling behavior.
