Self-Assembly of Discrete Oligomers of Naphthalenediimides in Bulk and on Surfaces
Here, we report on the synthesis of discrete oligomers of alkyl-bridged naphthalenediimides (NDIs) and study their molecular nanostructures both in bulk, in solution, and at the liquid-solid interface. Via an iterative synthesis method, multiple NDI cores were bridged with short and saturated alkyl-diamines (C3 and C12 ) or long and unsaturated alk...
3D Non-Newtonian deposition flow and thermal simulations to evaluate the scale-up potential for material extrusion of si...
Material extrusion (MEX) is one of the most widely used additive manufacturing (AM) techniques for polymeric materials. In the present work, 3D simulations using Ansys Polyflow are employed to address two MEX challenges: (i) avoiding sub-optimal thermal control in the deposited part, with a too low temperature leading to a weak bond between individ...
The effect of coolant additives on the vapour explosion behaviour in melt droplet impingement experiments
Vapour explosions are a known hazard with potentially devastating consequences in several industries. They might occur when a hot liquid comes into direct contact with a cold and volatile liquid. Eutectic PbS-Cu2S droplet impingement experiments were performed to investigate the effect of the coolant composition on the vapour explosion behaviour. T...
Separating Kinetics From Relaxation Dynamics in Reactive Soft Matter by Dielectric Spectroscopy
Broadband dielectric spectroscopy (BDS) is a widely used technique for the study of molecular and cooperative dynamics in soft matter thanks to its extremely wide time- and frequency-range and its widespread availability in materials science laboratories. A specific area for applications of BDS is systems that undergo time dependent changes because...

Recent Insights about the Role of Gels in Organic Photonics and Electronics
This review article provides an in-depth exploration of the role of gels in the fields of organic electronics and photonics, focusing on their unique properties and applications. Despite their remarkable potential, gel-based innovations remain relatively uncharted in these domains. This brief review aims to bridge the knowledge gap by shedding ligh...
Surface Modulation via Conjugated Bithiophene Ammonium Salt for Efficient Inverted Perovskite Solar Cells
...
The metal halide perovskite absorbers are prone to surface defects, which severely limit the power conversion efficiencies (PCEs) and the operational stability of the perovskite solar cells (PSCs). Herein, trace amounts of bithiophene propylammonium iodide (bi-TPAI) are applied to modulate the surface properties of the gas-quenched perovskite. It i...

Disordered Phase-Assisted Growth of Organic Semiconductor Crystals on Self-Assembled Monolayer Templates
...
Achieving high mobility and bias stability is a challenging obstacle in the advancement of organic thin-film transistors (OTFTs). To this end, the fabrication of high-quality organic semiconductor (OSC) thin films is critical for OTFTs. Self-assembled monolayers (SAMs) have been used as growth templates for high-crystalline OSC thin films. Despite ...
