The paper describes our experience of the design and utilization of a substrate for mobile objects that resides in the middleware layer. It has helped us to develop mobile object/agent systems including a heterogeneous mobile object system, mobile programming language systems, and mobile Web-search robots.

Layer-by-layer (LbL) assembly has attracted much attention because of its ability to create multifunctional films on surfaces while maintaining bulk properties. The method relies on sequential adsorption of polymers onto bulk surfaces from solution, giving rise to complex multilayered films. LbL assembly is simple to implement and offers extensive control over film properties and composition du...

We predict the existence of low-frequency nonlocal plasmons at the vacuum-surface interface of a superlattice of N graphene layers interacting with conducting substrate. We derive a dispersion function that incorporates the polarization function of both the graphene monolayers and the semi-infinite electron liquid at whose surface the electrons scatter specularly. We find a surface plasmon-pola...

Submitted for the MAR08 Meeting of The American Physical Society Ripples in epitaxial graphene FRANCOIS VARCHON, PIERRE MALLET, JEAN-YVES VEUILLEN, LAURENCE MAGAUD, Institut Neel CNRS/UJF — On the basis of extensive ab initio calculation supported by scanning tunneling experiments, we have elucidated the complex morphology of the graphene/SiC (0001) interface [1]. We demonstrate that a carbon b...

Using a combination of TEM and XPS, we made an analysis of the complex high-temperature annealing effect on ultrathin titanium deuteride (TiD(y)) films evaporated on a Si(100) substrate and covered by an ultrathin palladium layer. Both the preparation and annealing of the TiD(y)/Pd bi-layer films were performed in situ under UHV conditions. It was found that the surface and bulk morphology of t...

Cationic and anionic block copolymer worms are prepared by polymerization-induced self-assembly via reversible addition-fragmentation chain transfer (RAFT) aqueous dispersion copolymerization of 2-hydroxypropyl methacrylate and glycidyl methacrylate (GlyMA), using a binary mixture of a nonionic poly(ethylene oxide) macromolecular RAFT agent and either a cationic poly([2-(methacryloyloxy)ethyl]t...

Among the limitations for use of direct seeding in ecological restoration severely degraded areas tropical grasslands, association between dry periods and an inhospitable substrate stands out. This work evaluated whether covering seed with a soil layer addition thin topsoil to interferes native plant establishment areas. The effect rainfall variations on results was also measured. seven species...

The aim of this work is to study the effect of operating frequency, piezoelectric substrate and waveguide layer thickness on the sensitivity of the acoustic waveguide sensor during the specific binding of an antibody by a protein. Shear horizontal (SH) wave devices consisting of (a) a LiTaO3 substrate operating at 104 MHz, (b) a quartz substrate operating at 108 MHz and (c) a quartz substrate o...
