Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Lifestyles, choice of housing location and daily mobility. Conceptual framework, methods and preliminary results of the interdisciplinary research project "StadtLeben" [PDF]

open access: yes
Today, spatial research and planning is confronted with complex frame conditions which have substantially changed in the past decades. Thus, a comprehensive social change is stated, giving new room for individual development, but on the other hand making

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Going Beyond Walkability: Development of a Neighbourhood Active Living Environment Index in the Oriscav-Lux Study

open access: yesBaltic Journal of Sport and Health Sciences
Purpose: The walkability index (WI) is considered the gold standard in environmental research on physical activity (PA) but overlooks key environmental characteristics conducive for an active lifestyle. We developed a more comprehensive index, the Active

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

LABOR MOBILITY AND SPATIAL DENSITY [PDF]

open access: yes, 2011
This paper focuses on a much cited but seldom measured micro-foundation for agglomerations: inter-firm labor mobility. Labor mobility has been advanced as a vehicle for knowledge flows and labor market efficiency, and is often maintained to be an important source of agglomeration economies.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

An Exploration of Artistic Expressions of Everyday Peri-Urban Landscapes as a Method of Socio-Spatial Analysis in Spatial Planning

open access: yesArchitecture
Everyday landscapes, including peri-urban areas, play a pivotal role in shaping our physical and mental environments. Nevertheless, spatial planning often falls short of integrating contemporary everyday life and lived space.
