  Abstract = The nano-modification of selected substrates by means of atmospheric
     cold plasma treatment was exploited for the two-dimensional (2D)
     self-assembling of silver nanoparticles (Ag NPs). Such a useful
     combination of the cold plasma treatment of substrate surface and an
     immediate easy deposition of Ag NPs creating the 2D self-assemblies on
     the substrates is published for the first time, to the best of our
     knowledge. Except for the cold plasma treatment, mainly the following
     parameters influenced the resulting NP assemblies: the choice of solvent
     mixture, concentration of Ag NP dispersions, and the deposition
     technique. The 2D self-assemblies of Ag NPs, providing the same work
     function as a Ag electrode, were formed on the cold plasma-treated
     substrates when a drop-casting technique was employed. The possibility
     of an easy preparation of the Ag NP 2D self-assemblies on substrates
     without using any chemical agents and/or evaporating chamber could be
     exploited, e.g. in photovoltaic and light-emitting diode devices.,

  Abstract = The paper addresses the wear particles released from commercially
     available ``low-metallic'' automotive brake pads subjected to brake
     dynamometer tests. Particle size distribution was measured in situ and
     the generated particles were collected. The collected fractions and the
     original bulk material were analyzed using several chemical and
     microscopic techniques. The experiments demonstrated that airborne wear
     particles with sizes between 10 nm and 20 mu m were released into the
     air. The numbers of nanoparticles (< 100 nm) were by three orders of
     magnitude larger when compared to the microparticles. A significant
     release of nanoparticles was measured when the average temperature of
     the rotor reached 300 degrees C, the combustion initiation temperature
     of organics present in brakes. In contrast to particle size distribution
     data, the microscopic analysis revealed the presence of nanoparticles,
     mostly in the form of agglomerates, in all captured fractions. The
     majority of elements present in the bulk material were also detected in
     the ultra-fine fraction of the wear particles. (C) 2010 Elsevier Ltd.

  Abstract = Stoichoimetric graphene fluoride monolayers are obtained in a single
     step by the liquid-phase exfoliation of graphite fluoride with
     sulfolane. Comparative quantum-mechanical calculations reveal that
     graphene fluoride is the most thermodynamically stable of five studied
     hypothetical graphene derivatives; graphane, graphene fluoride, bromide,
     chloride, and iodide. The graphene fluoride is transformed into graphene
     via graphene iodide, a spontaneously decomposing intermediate. The
     calculated bandgaps of graphene halides vary from zero for graphene
     bromide to 3.1 eV for graphene fluoride. It is possible to design the
     electronic properties of such two-dimensional crystals.,
