Drops can bounce from perfectly hydrophilic surfaces

Drops are well known to rebound from superhydrophobic surfaces and from liquid surfaces. Here, we show that drops can also rebound from a superhydrophilic solid surface such as an atomically smooth mica sheet. However, the coefficient of restitution CR ass ...

Hydrogen and Hydrogen Peroxide Formation in Trifluorotoluene-Water Biphasic Systems

Hubert Girault, Jonnathan Cesar Hidalgo Acosta

Hydrogen or hydrogen peroxide can be generated in liquid-liquid biphasic systems, where the organic phase contains sufficiently strong electron donor (whose redox potential is lower than the potential of reversible hydrogen electrode). H2O2 generation with ...

The interplay between apparent viscosity and wettability in nanoconfined water

Kislon Voitchovsky

Understanding and manipulating fluids at the nanoscale is a matter of growing scientific and technological interest. Here we show that the viscous shear forces in nanoconfined water can be orders of magnitudes larger than in bulk water if the confining sur ...

Wagging the Tail: Essential Role of Substrate Flexibility in FAAH Catalysis

Ursula Röthlisberger, Andrea Cavalli, Pablo Campomanes Ramos, Giulia Palermo, Marilisa Neri

The serine hydrolase, fatty acid amide hydrolase (FAAH), is responsible for the intracellular degradation of anandamide and other bioactive fatty acid ethanolamides involved in the regulation of pain, inflammation, and other pathophysiological processes. T ...

Formation and Properties of Self-Assembly-Driven Fluorescent Nanoparticle Sensors

Paul Joseph Dyson, Zhaofu Fei

Fluorescent nanoparticles (FNPs) are obtained in water by self-assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interacti ...

Characterization of Three Amino-Functionalized Surfaces and Evaluation of Antibody Immobilization for the Multiplex Detection of Tumor Markers Involved in Colorectal Cancer

Vincent Laporte, Nicolas Xanthopoulos

Antibody microarrays are powerful and high-throughput tools for screening and identifying tumor markers from small sample volumes of only a few microliters. Optimization of surface chemistry and spotting conditions are crucial parameters to enhance antibod ...

On the Nature of Interactions of Radicals with Polar Molecules

Jeremy Samuel Arey, Peter Rudolf Tentscher

Solvated radicals play an important role in many areas of chemistry, but to date, the nature of their interactions with polar solvent molecules lacks chemical interpretation. We present a computational quantum chemical analysis of the binding motives of bi ...

Atomic Force Measurements of Hydrophobic Interactions

Julien Perroset

This semester project comes within the scope of studies at the nanometre scale. The experimental techniques used in this work are related to atomic force microscopy, which gives a direct access to the topography and forces of the studied systems. The goal ...

Excellent Correlation between Drug Release and Portal Size in Metalla-Cage Drug-Delivery Systems

Paul Joseph Dyson, Olivier Pierre Zava

A series of large cationic hexanuclear metalla-prisms, Ru-6(p-iPrC(6)H(4)Me)(6)(tpt)(2)(donq)(3), Ru-6(p-iPrC(6)H(4)Me)(6)(tpt)(2)(doaq)(3) and Ru-6(p-iPrC(6)H(4)Me)(6)(tpt)(2)(dotq)(3), composed of p-cymene-ruthenium building blocks brid ...

Ordering Surfaces on the Nanoscale: Implications for Protein Adsorption

Francesco Stellacci

Monolayer-protected metal nanoparticles (MPMNs) are a newly discovered class of nanoparticles with an ordered, striped domain structure that can be readily manipulated by altering the ratio of the hydrophobic to hydrophilic ligands. This property makes the ...
