Article Abstract
Purposely tailored thin film stacks sustaining surface waves have been utilized to create a unique link between emission angle and wavelength of fluorescent dye molecules. The knowledge of the thin film stack's properties allows us to derive the intrinsically emitted luminescence spectrum as well as to gain information about the orientation of fluorophores from angularly resolved experiments. This corresponds to replacing all the equipment necessary for polarized spectroscopy with a single smart thin film stack, potentially enabling single shot analyses in the future. The experimental results agree well with those from other established techniques, when analyzing the Rubrene derivative in a 2,4,6-tris(biphenyl-3-yl)-1,3,5-triazine (T2T) host used for the fabrication of optimized organic light-emitting diodes. The findings illustrate how resonant layered stacks can be applied to integrated spectroscopic analyses.

In this study, we analyze InO thin-film transistors (InO-TFT) using synchrotron-based hard X-ray photoelectron spectroscopy (HAXPES) in conditions. A bottom-gate InO-TFT with a high- AlO gate dielectric, grown on thermally oxidized silicon (SiO/p-Si), was examined while operating at varying and . The results reveal that the In 3d core level binding energy varies along the horizontal channel length, driven by the potential gradient induced by .

Iridescent coloration is a vibrant structural colour that is widespread in nature, but in mammals is thought to be limited. Although multiple rodent and Eulipotyphlan species have been anecdotally described as iridescent, empirical evidence outside of the Chrysochloridae (golden mole) family is lacking. As iridescence in golden moles is created through a thin-film mechanism from a compressed cuticle structure, and the structure of hair is highly conserved, we expect iridescence to be present, and produced by the same mechanism, in mammals that share similar hair properties.

Undesired ice accumulation on infrastructure and transportation systems leads to catastrophic events and significant economic losses. Although various anti-icing surfaces with photothermal effects can initially prevent icing, any thawy droplets remaining on the horizontal surface can quickly re-freezing once the light diminishes. To address these challenges, we have developed a self-draining slippery surface (SDSS) that enables the thawy droplets to self-remove on the horizontal surface, thereby facilitating real-time anti-icing with the aid of sunlight (100 mW cm).

The processes of thermoforming 2D-printed electronics into 3D structures can introduce defects that impact the electrical performance of conductors, making them more susceptible to thermal failure during high electrical power/current applications on temperature-sensitive substrates. We therefore report the use of a thin-film boron nitride nanotube (BNNT) interlayer to directly reduce heat stress on linear and serpentine metallic traces on polycarbonate substrates thermoformed to 3D spherocylindrical geometries at varying elongation percentages. We demonstrate that the BNNT interlayer helps to improve the electrical conductivity of highly elongated thermoformed 3D traces in comparison to traces on bare polycarbonate.
