Changes in portlandite morphology with solvent composition: Atomistic simulations and experiment

Paul Bowen, Sandra Caroline Galmarini, Nicolas Ruffray

Experimental work has been done to determine changes in the particle shape of portlandite grown in the presence of different ions. To quantify the experimentally observed changes in morphology a new analysis tool was developed, allowing the calculation of ...

Dispersible exfoliated zeolite nanosheets and their application as a selective membrane

Xiuwei Zhang, Matteo Cococcioni, Sanjeev Kumar

Thin zeolite films are attractive for a wide range of applications, including molecular sieve membranes, catalytic membrane reactors, permeation barriers, and low-dielectric-constant materials. Synthesis of thin zeolite films using high-aspect-ratio zeolit ...

Synthesis, characterization, DNA interaction and potential applications of gold nanoparticles functionalized with Acridine Orange fluorophores

Alberto Schena

Two new water-soluble gold nanoparticles (AO-TEG-Au and AO-PEG-Au NPs) are prepared and characterized. They are stabilized by thioalkylated oligoethylene glycols and functionalized with fluorescent Acridine Orange (AO) derivatives. Despite the different co ...

Impact of virus aggregation on inactivation by peracetic acid and implications for other disinfectants

Tamar Kohn, Paolo Perona, Benoît Crouzy, Krista Rule Wigginton, Michael Jon Mattle, Moritz Brennecke

Viruses in wastewater and natural environments are often present as aggregates. The disinfectant dose required for their inactivation, however, is typically determined with dispersed viruses. This study investigates how aggregation affects virus inactivati ...

On A Model For Mass Aggregation With Maximal Size

Ondrej Budác, Andrej Spielmann

We study a kinetic mean-field equation for a system of particles with different sizes, in which particles are allowed to coagulate only if their sizes sum up to a prescribed time-dependent value. We prove well-posedness of this model, study the existence o ...

Bloch Surface Wave Biosensing

Vincent Paeder

The process of protein aggregation, due to an incorrect protein folding, has very important implications in medicine. An increasing number of pathologies, including Alzheimer's and Parkinson's diseases, are associated unambiguously with the formation of la ...

Statistical analysis of subnanometer residual disorder in photonic crystal waveguides: Correlation between slow light properties and structural properties

Romuald Houdré, Hua Zhang, Nicolas Le Thomas, Zhaolu Diao

The authors present a statistical study of residual disorder in nominally identical planar photonic crystal waveguides operating in the slow light regime. The focus is on the role played by the subnanometer scaled residual disorder inherent to state-of-the ...

Particle dynamics in high-Alpine proglacial reservoirs modified by pumped-storage operation

Alfred Johny Wüest

Temperature and suspended particle distribution were surveyed and modeled in two high-Alpine reservoirs in Switzerland, connected by pumped-storage operations for similar to 30 years. Due to different glacier coverage of the catchments, the two reservoirs ...

Influence of the initial state of carbon nanotubes on their colloidal stability under natural conditions

Arnaud Magrez, Laura Sigg

The colloidal stability of dry and suspended carbon nanotubes (CNTs) in the presence of amphiphilic compounds (i.e. natural organic matter or surfactants) at environmentally realistic concentrations was investigated over several days. The suspensions were ...
