Production and Characterization of Vacuum Deposited Organic Light Emitting Diodes

Daniel de Sa Pereira¹, Andrew P. Monkman¹, Przemyslaw Data^1,2,3

¹Physics Department, Durham University, ²Faculty of Chemistry, Silesian University of Technology, ³Centre of Polymer and Carbon Materials, Polish Academy of Science

A protocol for the production of simple structured organic light-emitting diodes (OLEDs) is presented.

Chemistry

Electrochemical Impedance Spectroscopy as a Tool for Electrochemical Rate Constant Estimation

Pavel Chulkin¹, Przemyslaw Data^1,2,3

¹Factulty of Chemistry, Department of Physical Chemistry and Technology of Polymers, Silesian University of Technology, ²Department of Physics, Durham University, ³Centre of Polymer and Carbon Materials of the Polish Academy of Sciences

Electrochemical impedance spectroscopy (EIS) of species that undergo reversible oxidation or reduction in solution was used for determination of rate constants of oxidation or reduction.

JoVE Core

Time-resolved Photophysical Characterization of Triplet-harvesting Organic Compounds at an Oxygen-free Environment Using an iCCD Camera

Piotr Pander¹, Przemyslaw Data^1,2,3, Fernando B. Dias¹

¹Department of Physics, University of Durham, ²Faculty of Chemistry, Silesian University of Technology, ³Center of Polymer and Carbon Materials, Polish Academy of Sciences

Here, we present a method of the spectroscopic characterization of organic molecules by means of time-resolved photoluminescence spectroscopy on the nanosecond-to-millisecond timescale in oxygen-free conditions. Methods to efficiently remove oxygen from the samples and, thus, limit luminescence quenching are also described.

Using Cyclic Voltammetry, UV-Vis-NIR, and EPR Spectroelectrochemistry to Analyze Organic Compounds

Sandra Pluczyk¹, Marharyta Vasylieva¹, Przemyslaw Data^1,2,3

¹Faculty of Chemistry, Department of Physical Chemistry and Technology of Polymers, Silesian University of Technology, ²Department of Physics, Durham University, ³Center of Polymer and Carbon Materials of the Polish Academy of Sciences

In this article, we describe electrochemical, electron paramagnetic resonance, and ultraviolet-visible and near-infrared spectroelectrochemical methods to analyze organic compounds for application in organic electronics.

Effectiveness of the Air Stripping in Two Salmonid Fish, Rainbow Trout (Oncorhynchus Mykiss) and Brown Trout (Salmo Trutta Morpha fario)

Radosław Kajetan Kowalski¹, Beata Sarosiek¹, Sylwia Judycka¹, Katarzyna Dryl¹, Joanna Grudniewska², Stefan Dobosz², Beata Irena Cejko¹

¹Department of Gamete and Embryo Biology, Institute of Animal Reproduction and Food Research, Polish Academy of Science, ²Department of Salmonid Fish Research, The Stanisław Sakowicz Inland Fisheries Institute

The principal aim of this study is to standardize and test the pneumatic method (air stripping) of collecting eggs in rainbow trout and brown trout. This method allows effective and simple collection of the eggs without the necessity of fish abdomen massage.
