Tuning the Properties of Hydrogel Microspheres by Adding Chemical Cross-linking Functionality to Sodium Alginate

Sandrine Gerber, François Rémi Pierre Noverraz, Jutta Christine Wandrey, Redouan Mahou, Solène Marcelle Françoise Marie Passemard, Françoise Borcard, Virginia Crivelli, Léo Bühler

Two novel types of hydrogel microspheres (MS) are presented. First, one-component microspheres (1-comMS) were produced from sodium alginate (Na-alg) equipped with thiolfunctionalized hydroxyl groups. The functionalization pathway included the conversion of ...

Influence of Elemental Iodine on Imidazolium-Based Ionic Liquids: Solution and Solid-State Effects

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Felix Daniel Bobbink, Emilia Paunescu

Ionic liquids doped with I-2, usually resulting in the formation of polyiodide anions, are extensively used as electrolytes and in iodination reactions. Herein, NMR spectroscopy and single-crystal X-ray diffraction were used to rationalize the structures o ...

Solubility and Crystallizability: Facile Access to Functionalized pi-Conjugated Compounds with Chlorendylimide Protecting Groups

Rosario Scopelliti, Holger Frauenrath, Jan Cornelius Brauer, Stéphane Suarez, Roman Niklaus Marty, Jan Gebers, Damien Rolland, Luca Cervini

Functional pi-conjugated molecules are relevant for the preparation of new organic electronic materials with improved performance. However, their synthesis is often rendered difficult by their inherently low solubility, and the permanent attachment of solu ...

Thermal control of ionic transport and fluid flow in nanofluidic channels

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

In this work, we report a nanofluidic gating mechanism that uses the thermal effect for modulating the ionic transport inside nanofluidic channels. The control of the ionic transport inside a nanochannel is demonstrated using electrical conductivity. A the ...

In-situ mapping of the molecular arrangement of amphiphilic dye molecules at the TiO2 surface of dye sensitized solar cells

Ursula Röthlisberger, Francesco Stellacci, Ivano Tavernelli, Nicolas Tétreault, Kislon Voitchovsky, Negar Ashari Astani, Hauke Arne Harms

Amphiphilic sensitizers are central to the function of dye-sensitized solar cells. It is known that the cells performance depends on the molecular arrangement and the density of the dye on the semiconductor surface, but a molecular-level picture of the cel ...

Efficient dye regeneration at low driving force achieved in triphenylamine dye LEG4 and TEMPO redox mediator based dye-sensitized solar cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Yan Hao

Minimizing the driving force required for the regeneration of oxidized dyes using redox mediators in an electrolyte is essential to further improve the open-circuit voltage and efficiency of dye-sensitized solar cells (DSSCs). Appropriate combinations of r ...

Vapor-fed microfluidic hydrogen generator

Demetri Psaltis, Christophe Moser, Sophia Haussener, Miguel Antonio Modestino, Seyyed Mohammad Hosseini Hashemi, Mikaël Dumortier

Water-splitting devices that operate with humid air feeds are an attractive alternative for hydrogen production as the required water input can be obtained directly from ambient air. This article presents a novel proof-of-concept microfluidic platform that ...

Dye-sensitized Solar Cells: New Approaches with Organic Solid-state Hole Conductors

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Jiahuan Zhang

Solid-state dye-sensitized solar cells (sDSCs) in which a solid organic charge-transfer medium, or hole conductor (HC), is interposed between a dye-coated mesoporous oxide electrode and a conductive counter electrode, have attracted considerable interest a ...

Fluorescence lifetime imaging to differentiate bound from unbound ICG-cRGD both in vitro and in vivo

Edoardo Charbon, Claudio Bruschini, Harald Arjan Robert Homulle, François Eric Powolny, Riccardo Sinisi

Excision of the whole tumor is crucial, but remains difficult for many tumor types. Fluorescence lifetime imaging could be helpful intraoperative to differentiate normal from tumor tissue. In this study we investigated the difference in fluorescence lifeti ...

Robust production of purified H-2 in a stable, self-regulating, and continuously operating solar fuel generator

Sophia Haussener, Miguel Antonio Modestino

The development of practical solar-driven electrochemical fuel generators requires the integration of light absorbing and electrochemical components into an architecture that must also provide easy separation of the product fuels. Unfortunately, many of th ...
