This paper is devoted to an investigation of the effects of surface structure (structure-less or structured) on the description of the adsorption isotherm and the isosteric heat of nitrogen and argon adsorption onto graphitized thermal carbon black. It was found that the surface structure had little effect on the adso…

Semiconductor transformation of lead zirconate titanate (PZT)‐5H ferroelectric ceramics induced by hydrogen has been investigated. The results showed that hydrogen caused the PZT‐5H ferroelectric ceramics to transform from a yellow insulator into a black n ‐type semiconductor, and the leakage current and carrier conce…

At room temperature, Ba0.5Sr0.5TiO3 films can be distorted into in-plane or out-of-plane tetragonal structure depending on the type of film strain while the bulk ferroelectric is in a paraelectric phase (i.e., cubic). The film distortion can be accompanied with or without strain-induced permanent polarization dependin…

Vitrification of nuclear wastes is attractive because of its flexibility, the large number of elements which can be incorporated in the glass, its high corrosion durability and the reduced volume of the resulting waste form. Vitrification is a mature technology and has been used for high level nuclear waste (HLW) immo…

Abstract Low‐pressure plasmas are known for their ability to synthesize nanoparticles via gas‐phase nucleation. While in the past this particle formation has often been considered from the viewpoint of a contamination problem in semiconductor processing, we here describe a low‐pressure plasma that enables the synthesi…

It is established that magnesium oxide (a nonmagnetic ionic insulator) exhibits a transition to the state of a magnetic half-metal upon the introduction of nonmagnetic impurities (boron, carbon, or nitrogen) into the crystal lattice. The possibility of obtaining novel magnetic materials for spintronics by doping ionic…

Using Stokesian dynamics simulations, the shear-induced diffusivities due to pair collisions of identical spherical or nonspherical particles are considered, with the purpose to evaluate the effects of irreversibility and symmetry breaking. Results are compared to an approximate upper bound found by assuming that the…

Fluorosilane self-assembled monolayers for polydimethylsiloxane (PDMS) nanochannels are desirable to control the hydrophobicity of the surface to reduce or prevent undesired protein adsorption or cell interactions, critical for the performance of many biomedical micro-/nanodevices. Surface modifications using vapor ph…

The effects of Co, Fe, Mn, and Ti oxide additions on the sinterability and crystal-chemical, thermal, and electrical properties of Ce 0.8 Gd 0.2 O 2−δ have been studied. The results indicate that these oxides enhance the sinterability of the mixed oxide, regardless of whether they were introduced before or after synth…

We study the phase transition from amorphous to face-centered-cubic (fcc) polycrystalline Ge2Sb2Te5 thin films. The transformation has the peculiar characteristic, still not well understood, of coexisting high transition rates at low annealing temperature (with grain growth velocities of the order of 1nm∕min at 140°C)…

We show that a semi-infinite magnetoelectric (ME) material adjoining a vacuum sustains the propagation of a shear horizontal wave accompanied by electromagnetic waves. The ME material is assumed to possess hexagonal (6 mm) symmetry. The expression for the phase velocity of this wave is obtained explicitly. The result…
