Light-Based Printing of Leachable Salt Molds for Facile Shaping of Complex Structures

Cyril Dénéréaz

3D printing is a powerful manufacturing technology for shaping materials into complex structures. While the palette of printable materials continues to expand, the rheological and chemical requisites for printing are not always easy to fulfill. Here, a uni ...

Ion and Trap Induced Dynamic Phenomena in Salt Semiconductor Devices

Matthias Diethelm

State-of-the-art organic light-emitting diodes (OLEDs) used in commercial display technology are complex multilayer structures. In contrast, the light-emitting electrochemical cell (LEC) can be built from a single emissive layer sandwiched between two elec ...

Enhanced Room-Temperature Photoluminescence Quantum Yield in Morphology Controlled J-Aggregates

Frank Nüesch, Jakob Heier, Surendra Babu Anantharaman

Supramolecular assemblies from organic dyes forming J-aggregates are known to exhibit narrowband photoluminescence with full-width at half maximum of approximate to 9 nm (260 cm(-1)). Applications of these high color purity emitters, however, are hampered ...

Local Structure and Dynamics in Methylammonium, Formamidinium, and Cesium Tin(II) Mixed-Halide Perovskites from Sn-119 Solid-State NMR

David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz

Organic-inorganic tin(II) halide perovskites have emerged as promising alternatives to lead halide perovskites in optoelectronic applications. While they suffer from considerably poorer performance and stability in comparison to their lead analogues, their ...

Phase behaviour and structure of a model biomolecular condensate

Julian Charles Shillcock

Phase separation of immiscible fluids is a common phenomenon in polymer chemistry, and is recognized as an important mechanism by which cells compartmentalize their biochemical reactions. Biomolecular condensates are condensed fluid droplets in cells that ...

Oxidative Print Light Synthesis Thin Film Deposition of Prussian Blue

Hubert Girault, Emad Oveisi, Mounir Driss Mensi, Wanderson Oliveira Da Silva, Victor Costa Bassetto, Dominika Baster

Prussian blue (PB) and Prussian blue analogues (PBAs) are commonly synthesized by conventional methods, such as chemical precipitation, thermal decomposition, and electrochemical deposition. Herein, we have successfully synthesized Prussian blue by oxidati ...

A multi-technique approach to study the microstructural properties of tin-based transparent conductive oxides

Federica Landucci

Transparent conductive oxides (TCOs) are semiconductor-like materials that exhibit high electrical conductivity and high optical transparency combined. They are adopted in various applications ranging from gas sensors, to electrochromic windows, to photovo ...

Photoelectrochemical Polymerization of EDOT for Solid State Dye Sensitized Solar Cells: Role of Dye and Solvent

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

The aromatic-unit, commercially available, and cost-effective precursor 3, 4-ethylenedioxythiophene (EDOT), was employed instead of bis-EDOT to generate by in-situ photoelectrochemical polymerization (PEP) a conducting polymer-type hole conductor poly (3, ...
