New Developments in Amorphous Silicon Based Microchannel Plates

Christophe Ballif, Luca Massimiliano Antognini, Samira Alexandra Frey, Mohammad Beygi

Microchannel plates fabricated from hydrogenated amorphous silicon (AMCPs) are a promising alternative to conventional glass microchannel plates. Their main advantages lie in their flexible fabrication processes, allowing for adaptable channel shapes and t ...

Colloidal transport and deposition through dense vegetation

David Andrew Barry, Li Chen, Congrong Yu

The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...

Interactions of Tris with rutile surfaces and consequences for in vitro bioactivity testing

Paul Bowen, Ulrich Aschauer

Tris(hydroxymethyl)aminomethane (Tris) has been used as the buffer in bioactivity testing for over two decades and has become a standard choice for the scientific community. While it is believed to be non-interacting, the extent of its interactions with ti ...

Inkjet-Printed Carbon Nanotube Electrodes Modified with Dimer-captosuccinic Acid-Capped Fe3O4 Nanoparticles on Reduced Graphene Oxide Nanosheets for Single-Drop Determination of Trifluoperazine

Hubert Girault, Andreas Stephan Lesch, Milica Jovic

Here we report the design of a disposable single-drop voltammetric sensor for the quantitative determination of antipsy-chotic drug trifluoperazine (TFP). The sensor was build using inkjet-printed carbon nanotube (CNT) electrodes which were modified with d ...

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 ...

Specific Ion Effects at the Interface of Nanometer-Sized Droplets in Water: Structure and Stability

Sylvie Roke, Halil Ibrahim Okur, Evangelia Zdrali

The interaction of ions with interfaces influences numerous processes in chemistry, physics, and biology, while different ion species behave differently at hydrophobic or hydrophilic interfaces. Despite its importance, ion specificity and its relation to s ...

The Diverse Nature of Ion Speciation at the Nanoscale Hydrophobic/Water Interface

Sylvie Roke, Halil Ibrahim Okur, Evangelia Zdrali

Many biological systems are composed of nanoscale structures having hydrophobic and hydrophilic groups adjacent to one another and in contact with aqueous electrolyte solution. The interaction of ions with such structures is of fundamental importance. Alth ...

Orthogonal Tip-to-Tip Nanocapillary Alignment Allows for Easy Detection of Fluorescent Emitters in Femtomolar Concentrations

Aleksandra Radenovic, Michael Graf, Po-Ling Chang

Here we present the realization of a novel fluorescence detection method based on the electromigration of fluorescent molecules within a nanocapillary combined with the laser excitation through a platinum (Pt)-coated nanocapillary. By using the Pt nanocapi ...

Redox Electrocatalysis of Floating Nanoparticles: Determining Electrocatalytic Properties without the Influence of Solid Supports

Hubert Girault, Astrid Johana Olaya Avendano, Pekka Eero Peljo, Micheal Diarmaid Scanlon, Evgeny Smirnov, Lucie Josette Renée Rivier

Redox electrocatalysis (catalysis of electron-transfer reactions by floating conductive particles) is discussed from the point-of-view of Fermi level equilibration, and an overall theoretical framework is given. Examples of redox electrocatalysis in soluti ...
