Influence of the airflow and humidity on the chain aggregation during the film-formation in a flexible waterborne polyurethane formulation.

Statement Of Objectives: Soft, waterborne polyurethane dispersions are indispensable components in many state-of-the-art materials, with applications ranging from binders for coatings and adhesives to matrixes for flexible devices. While the static bulk nanostructure of such systems is widely studied, the influence that environmental conditions such as relative humidity and airflow have on their film formation and phase segregation behavior in supported films is unknown.

Experiments: Here, we elucidate the nanostructure evolution occurring during drying of an industrially relevant, soft polyurethane, utilizing real-time, non-destructive grazing incidence X-ray scattering analysis.

Noninvasive Readout of the Kinetic Inductance of Superconducting Nanostructures.

The energy landscape of multiply connected superconducting structures is ruled by fluxoid quantization due to the implied single-valuedness of the complex wave function. The transitions and interaction between these energy states, each defined by a specific phase winding number, are governed by classical and/or quantum phase slips. Understanding these events requires the ability to probe, noninvasively, the state of the ring.

Unveiling the urban sports landscape: Profiling participants, motives, and policy implications.

Background: The lack of knowledge regarding urban sports poses pressing challenges for governments and sports organisations to deal with in light of its increasing popularity. To develop targeted policy strategies, more insight is needed into the features of urban sports. Therefore, this research aims to establish a profile of urban sports participants in terms of characteristics, behaviours in sports participation, and motives for sports participation.

Significant Oxygen Underestimation When Quantifying Barium-Doped SrTiO Layers by Atom Probe Tomography.

In this paper, the capability for quantifying the composition of Ba-doped SrTiO layers from an atom probe measurement was explored. Rutherford backscattering spectrometry and time-of-flight/energy elastic recoil detection were used to benchmark the composition where the amount of titanium was intentionally varied between samples. The atom probe results showed a significant divergence from the benchmarked composition.

Stuck between medals and participation: an institutional theory perspective on why sport federations struggle to reach Sport-for-All goals.

Background: Sport-for-All emphasizes that every individual has the right to participate in sport. Despite all efforts to deliver Sport-for-All during the past decades, studies indicate that sport participation rates have been stagnating, whereas social inequalities in sport continue to exist. By applying an institutional theory lens, this study sheds light on how the dual mission of sport federations, i.
