Dramatic effective mass reduction driven by a strong potential of competing periodicity

Corsin Battaglia, Helmuth Berger, Philipp Aebi

We present angle-resolved photoemission experiments on 1T-TiSe2 at temperatures ranging from 13K to 288K. The data evidence a dramatic renormalization of the conduction band below 100K, whose origin can be related to the new potential responsible for the c ...

Rheological behavior of concentrated hyperbranched polymer/silica nanocomposite suspensions

Yves Leterrier, Valérie Geiser

The rheological behavior of two hyperbranched polymer/silica suspensions with different dispersion states, surface chemistries, and concentrations of the silica nanoparticles was investigated in terms of viscoelastic properties, activation energy for visco ...

Minimal matter at the large hadron collider

Duccio Pappadopulo, Roberto Franceschini

We classify all possible new U(1)(Y) circle times SU(2)(L) circle times SU(3)(c) multiplets that can couple to pairs of SM particles. Assuming that production of such new particles is dominated by their gauge interactions we study their signals at LHC, fin ...

Characterization of glycoprotein E C-End of West Nile virus and evaluation of its interaction force with alpha V beta 3 integrin as putative cellular receptor

Giovanni Dietler

Recombinant polypeptide containing the 260-466 amino acid sequence of West Nile virus (WNV) strain LEIV-Vlg99-27889-human glycoprotein E (gpE, E260-466) was constructed. Immunochemical similarity between the E260-466 and gpE of WNV was proven by enzyme imm ...

Phase behaviour of the symmetric binary mixture from Thermodynamic Perturbation Theory

Nicolas Dorsaz, Giuseppe Foffi

We study the phase behaviour of symmetric binary mixtures of hard core Yukawa (HCY) particles via thermodynamic perturbation theory (TPT). We show that all the topologies of phase diagram reported for the symmetric binary mixtures are correctly reproduced ...

Control of morphology and nanostructure of copper and cobalt oxalates: Effect of complexing ions, polymeric additives and molecular weight

Heinrich Hofmann, Paul Bowen, Jacques Lemaître, Alke Fink, Nathalie Jongen

Precipitated oxalates are often nanostructured and can be used as precursors for nanostructured oxides for different applications. The modification of the particle shape and nanostructures of both copper and cobalt oxalates has been demonstrated using poly ...

Minimal matter at the LHC

Roberto Franceschini

A systematic approach for a model independent description of phenomenology at the LHC is presented. The most general linear interaction of scalars and fermions with pairs of standard model fields is considered at the renormalizable level. Searches for the ...

System-Dependent Density Based Dispersion Correction

Density functional approximations fail to provide a consistent description of weak molecular interactions arising from small electron density overlaps. A simple remedy to correct for the missing interactions is to add a posteriori an attractive energy term ...

Stable -Synuclein Oligomers Strongly Inhibit Chaperone Activity of the Hsp70 System by Weak Interactions with J-domain Co-chaperones

Giovanni Dietler, Hilal Lashuel, Mounir Driss Mensi, Pierre Goloubinoff

alpha-Synuclein aggregation and accumulation in Lewy bodies are implicated in progressive loss of dopaminergic neurons in Parkinson disease and related disorders. In neurons, the Hsp70s and their Hsp40-like J-domain co-chaperones are the only known compone ...

High Extraction Efficiency GaN-Based Photonic-Crystal Light-Emitting Diodes: Comparison of Extraction Lengths between Surface and Embedded Photonic Crystals

Elison de Nazareth Matioli

This work presents the experimental measurement of the extraction lengths of individual guided modes of embedded photonic-crystal (PhC) light-emitting diodes (LEDs), which corroborates its superior guided light extraction compared to surface PhC LEDs. Whil ...
