Surface Characterization of Colloidal Silica Nanoparticles by Second Harmonic Scattering: Quantifying the Surface Potential and Interfacial Water Order

Sylvie Roke, Arianna Marchioro, Cornelis Ulrich Lütgebaucks, Marie Bischoff

The microscopic description of the interface of colloidal particles in solution is essential to understand and predict the stability of these systems, as well as their chemical and electrochemical reactivity. However, this description often relies on the u ...

Experimental evidence for long-range stabilizing and destabilizing interactions between charge and radical sites in distonic ions

Ganna Gryn'ova

Polarizable radical sites in distonic radical anions are stabilized by ostensibly remote negative charges. Computational evidence suggests bond dissociation energies of closed-shell precursors are significantly lowered by through-space interactions with a ...

Interparticle Friction Leads to Nonmonotonic Flow Curves and Hysteresis in Viscous Suspensions

Matthieu Wyart, Hugo Robin Louis Perrin

Hysteresis is a major feature of the solid-liquid transition in granular materials. This property, by allowing metastable states, can potentially yield catastrophic phenomena such as earthquakes or aerial landslides. The origin of hysteresis in granular fl ...

Electrical transport in onion-like carbon-PMMA nanocomposites

László Forró, Arnaud Magrez, Claudio Grimaldi, Maryam Majidian

We report electrical conductivity measurements of polymethyl-methacrylate filled by onion-like carbon particles with a primary particle size of approximate to 5 nm. We show that the conductivity sigma is exceptionally high even at very low loadings and tha ...

Rheological behavior of colloidal suspension with long-range interactions

In this work, we study the constitutive behavior of interacting colloidal suspensions for moderate and high concentrations. Specifically, using a lattice Boltzmann solver, we numerically examine suspensions flowing through narrow channels, and explore the ...

Spatial and temporal turbidity currents sediment deposition assessment

Giovanni De Cesare, Shun Nomura

Flume experiments are conducted to model sediment-laden density currents with continuous suspension supply. The initial density covers 1008, 1016, and 1032 kg/m3 and the bottom slope at 5.0 %. Sediment deposition profiles along the experimental flume are m ...

Superweak Coordinating Anion as Superstrong Enhancer of Cyanine Organic Semiconductor Properties

Frank Nüesch, Jakob Heier, Antonia Neels, Donatas Gesevicius

The superweak tetrakis(nonafluoro-tert-butoxy)aluminate coordinating anion was employed to introduce pseudo-gas-phase conditions to the 2-[5-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)-1,3-pentadien-1-yl]-1,3,3-trimethyl-3H-indolium chromophore. The r ...

Particle size-segregation in granular ows driven by a conveyor belt.

Christophe Ancey, Tomás Alfredo Trewhela Palacios, Kasper van der Vaart

Particle motion within the leading edge of bidisperse gravity-driven granular flows is affected by particle size segregation. Shear-induced segregation causes coarse particles to move towards the upper layers. Then, these are advected down to the tip regio ...

Energy and Charge Transfer Cascade in Methylammonium Lead Bromide Perovskite Nanoparticle Aggregates

Jacques-Edouard Moser, Joël Teuscher, Marine Eva Fedora Bouduban, Andrés Burgos Caminal, Rachele Ossola

Highly photoluminescent hybrid lead halide perovskite nanoparticles have recently attracted a wide interest in the context of high-stake applications, such as light emitting diodes (LEDs), light emitting transistors and lasers. In addition, they constitute ...

Inhalation intake fraction of particulate matter from localized indoor emissions

Dusan Licina

Elevated exposure to airborne particulate matter is linked to deleterious health and well-being outcomes. Exposure assessment can be improved through enhanced understanding of source-receptor relationships, for example as expressed in the inhalation intake ...
