CdSe Sensitized Thin Aqueous Films: Probing the Potential Distribution Inside Multilayer Assemblies

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

Ultrathin polypeptide multilayer films are assembled by the sequential electrostatic adsorption of monolayers of poly-L-lysine and poly-L-glutamic acid onto carboxylic acid terminated alkanethiol-modified gold surfaces. The polypeptide multilayer films are ...

Magnetism and superconductivity of strongly correlated electrons on the triangular lattice

Frédéric Mila, Cédric Weber, Thierry Giamarchi

We investigate the phase diagram of the t−J model on a triangular lattice using a variational Monte Carlo approach. We use an extended set of Gutzwiller projected fermionic trial wave functions allowing for simultaneous magnetic and superconducting order p ...

Insights into excited-state and isomerization dynamics of bacteriorhodopsin from ultrafast transient UV absorption

Majed Chergui, Frank van Mourik, Selma Schenkl

A visible-pump/UV-probe transient absorption is used to characterize the ultrafast dynamics of bacteriorhodopsin with 80-fs time resoln. We identify three spectral components in the 265- to 310-nm region, related to the all-trans retinal, tryptophan (Trp)- ...

Passive compliance for an (RC) servo-controlled bouncing robot

A novel and low-cost passively compliant mechanism is described that can be used with RC servos to actuate legged robots in tasks involving high dynamic loads such as bouncing. Compliance is achieved by combining visco-elastic material and metal parts. Joi ...

An energy balance criterion for nanoindentation-induced single and multiple dislocation events

William Curtin, Ronald Earle Miller

Small volume deformation can produce two types of plastic instability events. The first involves dislocation nucleation as a dislocation by dislocation event and occurs in nanoparticles or bulk single crystals deformed by atomic force microscopy or small n ...

Mesoscopic length scales for deformed nanostructures

William Curtin, Ronald Earle Miller

Defining mesoscopic length scales for deformed nanostructures requires a close coupling of theory and experiment. One approach to this is to mechanically probe single crystal nanospheres of the same size that can be evaluated computationally. This involves ...

Low-cost thick-film force sensors for the 100 N force range

Peter Ryser, Thomas Maeder, Giancarlo Corradini

This work presents calculations and measurements on a novel low-cost thick-film force sensor design for the 100 N force range. The mechanical concept of these force sensors is based on a double ring biaxial load, which allows the fabrication of simple sens ...

Spin Glass Models of Markov Random Fields

Barbara Caputo

This paper presents a novel algorithm for robust object recognition. We propose to model the visual appearance of objects via probability density functions. The algorithm consists of a fully connected Markov random field with energy function derived from r ...

Oscillating fracture paths in thin elastic sheets: when geometry rules the fracture path

Pedro Miguel Nunes Pereira de Almeida Reis

We report a novel mode of quasi-static oscillatory crack propagation when a cutting tool is driven through a thin polymer film [6,7]. In our experiments, for tools with a large enough width, the crack tip follows a highly periodic path, leaving behind a st ...

Systematic errors in computed alkane energies using B3LYP and other popular DFT functionals

Matthew Wodrich

Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range non-bonded attractive effects, are illust ...
