First-principles calculations of stacking fault energies in Mg-Y, Mg-Al and Mg-Zn alloys and implications for < c plus a > activity

William Curtin, Binglun Yin, Zhaoxuan Wu

Mg-3wt.%RE alloys show substantially enhanced < c + a > activity as compared to pure Mg or other Mg-Al, Mg-Zn alloys of similar grain sizes. Activation of < c + a > slip has been postulated to be associated with the reduction of the basal Li stacking fault ...

The Mass-Concentration Relation and the Stellar-to-halo Mass Ratio in the CFHT Stripe 82 Survey

Jean-Paul Richard Kneib, Johan Comparat, Huanyuan Shan

We present a new measurement of the mass-concentration relation and the stellar-to-halo mass ratio over the halo-mass range 5 x 10(12) to 2 x 10(14) M circle dot. To achieve this, we use weak lensing measurements from the Canada-France-Hawaii Telescope Str ...

Strengthening of high entropy alloys by dilute solute additions: CoCrFeNiAlx and CoCrFeNiMnAlx alloys

William Curtin, Céline Varvenne

A theory to predict the initial flow stress of an arbitrary N-component fcc random alloy is extended to predict the additional strengthening when a dilute concentration of a substitutional element is introduced. Assuming properties for the N-component allo ...

Measuring air borne nanoparticles for characterizing hyphenated RDD-SMPS-ICPMS instrumentation

Christian Ludwig, Mohamed Tarik, Adrian Hess

Scanning Mobility Particle Sizer (SMPS) and Inductively Coupled Plasma Mass Spectrometry (ICPMS), complemented by a Rotating Disk Diluter (RDD) to a hyphenated RDD-SMPS-ICPMS measuring setup, allow online and simultaneous determination of size distribution ...

Time-resolved size and element analysis of gas-borne nanoparticles

Adrian Hess

Physical and chemical characterization of gas-borne particles in the nanometer to sub-micrometer size range is important in many applications, such as nanoparticle related health studies, the monitoring of powder or dust distribution processes, assessing t ...

Effect of Very High Charge Density and Monomer Constitution on the Synthesis and Properties of Cationic Polyelectrolytes

Jutta Christine Wandrey, Ricardo Losada Mateo, Hamideh Ahmadloo

The free-radical homopolymerization of 1,3-bis(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and 1,3-bis(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A) in aqueous solution yields cationic polyelectrolytes (PEL) with theoretic ...

Evaluation des flux de biphényles polychlorés (PCBs) dans les affluents du lac Léman à l’aide de capteurs passifs

The aim of this study is to investigate Lake Geneva’s tributaries using passive samplers in order to establish polychlorinated biphenyl (PCB) fluxes. Silicon rubber sheets are therefore deployed during six weeks at the mouth of eight tributaries and in fou ...

Biomass-burning impact on CCN number, hygroscopicity and cloud formation during summertime in the eastern Mediterranean

Athanasios Nenes

This study investigates the concentration, cloud condensation nuclei (CCN) activity and hygroscopic properties of particles influenced by biomass burning in the eastern Mediterranean and their impacts on cloud droplet formation. Air masses sampled were sub ...

Effect of hydrostatic pressure on flow and deformation in highly reinforced particulate composites

Andreas Mortensen, Ludger Weber, Maria Gabriella Tarantino

Infiltrated particle reinforced composites combine a dense matrix with particles that are in mutual contact and can therefore transfer compressive stress directly from one particle to the next. As a result, these composites may combine characteristics of t ...

MASS-CONCENTRATION RELATION OF CLUSTERS OF GALAXIES FROM CFHTLenS

Jean-Paul Richard Kneib, Huanyuan Shan

Based on weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), in this paper we study the mass-concentration (M-c) relation for similar to 200 redMaPPer clusters in the fields. We extract the M-c relation by measuring the den ...
