Advanced Optical Materials, Volume 9, Issue 14, July 10, 2021., 2021 Top‐emitting p–i–n organic light‐emitting diodes often require robust thin film encapsulation and benefit from the use of highly reflective silver contacts. Here, the interface between silver and the p‐doped hole transport layer is identified as a potential weak point during encapsulation.

Emerging Biomedical Applications of Organic Light‐Emitting Diodes
Advanced Optical Materials, Volume 9, Issue 14, July 10, 2021., 2021 Organic light‐emitting diodes (OLEDs) make it possible to create free‐form, mechanically flexible light sources and high‐resolution displays, and are thus ideally suited for applications in biophotonics and medicine. This review discusses the technical challenges that need to be met to enable emerging applications of OLEDs in lab‐on‐chip settings, as ...

Significant otherness nation‐building and identity in postwar Austria
Nations and Nationalism, Volume 27, Issue 3, Page 782-796, July 2021., 2021 Abstract Nation‐building in Austria in the first half of the 20th century failed several times before it became possible to construct an independent Austrian nation after 1945. This article traces how Austria's handling of the Nazi era involved a demarcation from Germany, which became an identity‐determining alterity for the idea of an independent ...

Accurate Efficiency Measurements of Organic Light‐Emitting Diodes via Angle‐Resolved Spectroscopy
Advanced Optical Materials, Volume 9, Issue 1, January 4, 2021., 2021 Accurate characterization of organic light‐emitting diodes (OLEDs) is crucial for optimizing their efficiency, performance, and stability. Here, the implementation of a goniometer‐based measurement system and the analysis protocol are described that accurately determine the current–voltage–luminance characteristics, external quantum efficiency, and ...

Development of sensor nodes and sensors for smart farming
Journal of Electrochemical Science and Engineering, 2023 The world population is continuously increasing. Smart farming is required to keep up with this development by producing more food in a sustainable way. In many new sensor solution developments, the results of the sensor itself is at the target, but the

‘NACH UND NACH MÜSSEN WIR ALLES ABLEHNEN’: HYPERBOLISCHE NEGATIVITÄT BEI THOMAS BERNHARD
German Life and Letters, Volume 74, Issue 1, Page 30-46, January 2021., 2021 Abstract Thomas Bernhard's work abounds in rejections. The impulse of not wanting to participate, of refusing to be complicit, lies at the heart of Bernhard's oeuvre. If this refusal is frequently embedded in discursive or even programmatic strategies, it really seems to undermine its own foundations, the very arguments and justifications put forward ...

UN SECRETARY-GENERAL NORMATIVE CAPABILITY TO INFLUENCE THE SECURITY COUNCIL DECISION-MAKING PROCESS
Vestnik MGIMO-Universiteta, 2016 The present article studies the issue of the interrelation between the senior UN official - the Secretary-General and the main UN body - the Security Council. The nature of the Secretary-General role is ambiguous since the very creation of the UN. On one

Advanced Optical Materials, Volume 8, Issue 2, January 17, 2020., 2020 Here, a novel mechanism for mechanochromism based on reversible reconformation of a π‐conjugated polymer, poly(3‐tri(ethylene glycol) (P3TEOT), embedded into polyvinyl alcohol is presented. At high concentrations of P3TEOT, the blends undergo a stretching‐induced change of the color from orange to red along with the red‐shift in absorption and emission,
