Effusing source for film deposition of reservoir, comprises hole having hole diameter less than one order of magnitude than mean free path of molecules

Patrik Willi Hoffmann, Simone Amorosi, Giacomo Benvenuti

ECOLE POLYTECHNIQUE FEDERALE LAUSANNE (ECOL-Non-standard) BENVENUTI G (BENV-Individual) AMOROSI S (AMOR-Individual) HALARY-WAGNER E (HALA-Individual)2002

An overview is given on the experimental evidence suggesting that the magnitude of the initial fluctuations increases with cell size. For sufficiently thick cells, the magnitude is also shown to decrease over the entire time of the experiment, so that a st ...

Quantification of microdamage phenomena during tensile straining of high volume fraction particle reinforced aluminum

Andreas Mortensen, Ludger Weber, Marianna Kouzeli

Particle reinforced composites are produced by infiltrating ceramic particle beds with 99.99% Al. Resulting materials feature a relatively high volume fraction (40-55 vol. pet) of homogeneously distributed reinforcement. The evolution of damage during tens ...

The role of carrier mobility in holographic recording in LiNbO3

Demetri Psaltis

We investigate the role of carrier mobility in holographic recording in LiNbO3 crystals. Both normal holographic recording (single wavelength, single trap) and two-center recording are considered, and the differences between the performances of the two met ...

Mechanical properties of individual microtubules measured using atomic force microscopy

László Forró, Giovanni Dietler, Andras Kis, Andrzej Kulik, Sandor Kasas

Atomic force microscopy has been used to investigate the mechanical properties of microtubules. Method of Salvetat et al. [1], originally developed for measuring the Young's modulus of carbon nanotubes, has been extended to a biological system of similar g ...

High Pressure Cyanide Exchange Study on Square-planar Tetracyanometalate Complex of Pt(II)

André Merbach, Lothar Helm

Previous studies of cyanide exchange on square planar tetracyanoplatinate complex [Pt(CN)4]2- have been undertaken only at a high pH. For a more complete fundamental understanding of this system we extended the investigations of these exchanges over a larg ...

Electrochemical promotion of ruthenium oxide catalysts for the gas phase combustion of ethylene

Christos Comninellis

The electrochem. promotion of RuO2 catalyst films, deposed onto yttria stabilized zirconia solid electrolyte (YSZ), was studied for the gas phase combustion of ethylene. Two order of magnitude increase in the reaction rate was obtained during anodic polari ...

Estimates of vertical diffusivity inferred from microstructure measurements in the 2 thermocline of the open ocean (approximately 0.1 cm(2) s(-1)) are typically an order of magnitude smaller than values obtained with basin-wide tracer balances (approximate ...

Lifetime lengthenings of molecular Rydberg states in condensed matter

Majed Chergui, Franco Vigliotti

Lifetime studies of the NO A2S+ (v = 0) Rydberg fluorescence in rare gas matrixes are reported. The fluorescence stems from two types of sites, red and main. The red site fluorescence shows a lifetime lengthening of 25% in Kr matrixes and 100% in Xe matrix ...
