Matrix-Assisted Laser Desorption/Ionization Mass Spectrometric Analysis of Poly(3,4-ethylenedioxythiophene) in Solid-State Dye-Sensitized Solar Cells: Comparison of In Situ Photoelectrochemical Polymerization in Aqueous Micellar and Organic Media

Ulf Anders Hagfeldt, Nikolaos Vlachopoulos, Lin Yang

Solid-state dye-sensitized solar cells (sDSCs) are devoid of such issues as electrolyte evaporation or leakage and electrode corrosion, which are typical for traditional liquid electrolyte-based DSCs. Poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the ...

Polymer-theory insights into biomolecular systems

Salvatore Assenza

Boosted by the technological advances in experimental techniques, cellular biology is nowadays facing the need for quantitative approaches in order to rationalize the huge amount of collected data. A particularly succesfull theoretical framework is provide ...

Surface-initiated controlled radical polymerization enhanced DNA biosensing

Harm-Anton Klok, Tugba Bilgiç Tune

The surface chemistry at the DNA recognition and binding interface plays an important role in determining the performance of DNA microarrays and DNA biosensors. Surface-initiated controlled radical polymerization (SI-CRP) reactions represent a powerful too ...

Competing Interactions in the Self-Assembly of NC-Ph-3-CN Molecules on Cu(111)

Harald Brune, Marina Pivetta, Giulia Elisabetta Pacchioni

We report on low-temperature scanning tunneling microscopy and spectroscopy measurements on NC-Ph-3-CN molecules adsorbed at 300 K on a Cu(111) surface. Upon cooling, the molecules form chain and honeycomb structures, incorporating Cu adatoms supplied by t ...

Structure and rheology of star polymers in confined geometries: a mesoscopic simulation study

Dominic John Tildesley

Mesoscopic simulations of star polymer melts adsorbed onto solid surfaces are performed using the dissipative particle dynamics (DPD) method. A set of parameters is developed to study the low functionality star polymers under shear. The use of a new bond-a ...

Polymer Brush Gradients Grafted from Plasma-Polymerized Surfaces

Harm-Anton Klok, Tugba Bilgiç Tune

A new method for generating a surface density gradient of polymer chains is presented. A substrate-independent polymer deposition technique was used to coat materials with a chemical gradient based on plasma copolymerization of 1,7-octadiene and allylamine ...

Charge transfer relaxation in donor–acceptor type conjugated materials

Ursula Röthlisberger, Natalie Renuka Banerji, Mariateresa Scarongella, Andrey Laktionov

The development of conjugated materials bearing electron-rich and electron-poor units along their backbone introduces new possibilities to control functionality for organic electronic applications through charge transfer character in ground and excited sta ...

Effects of Molecular Weight on Microstructure and Carrier Transport in a Semicrystalline Poly(thieno)thiophene

Kevin Sivula, Andrea Gasperini

The ultimate control over chain self-assembly is key to unravel and optimize the relationship between film microstructure and charge carrier mobility in solution processable conjugated polymer semiconductors. Here we employ preparatory size exclusion chrom ...

Influence of Thermocouple Thermal Inertia in Impingement Heat Transfer Experiments Using Transient Techniques

Peter Ott, Alexandros Terzis, Bernhard Weigand, Guillaume Wagner

A typical transient heat transfer experiment for an impingement cooling configuration requires usually a temperature step in the flow. A moving isotherm of the liquid crystal surface coating is then monitored using a video camera. However, for small imping ...
