Signatures of an atomic crystal in the band structure of a C 60 thin film
Transport phenomena in molecular materials are intrinsically linked to the orbital character and the degree of localization of the valence states. Here we combine angle-resolved photoemission with photoemission tomography to determine the spatial distribution of all molecular states of the valence band structure of a C60 thin film. [...]

Plane-wave final state for photoemission from nonplanar molecules at a metal-organic interface
In recent years, the method of orbital tomography has been a useful tool for the analysis of a variety of molecular systems. However, the underlying plane-wave final state has been largely expected to be applicable to planar molecules only. [...]

Molecular anchoring stabilizes low valence Ni( i )TPP on copper against thermally induced chemical changes
Many applications of molecular layers deposited on metal surfaces, ranging from single-atom catalysis to on-surface magnetochemistry and biosensing, rely on the use of thermal cycles to regenerate the pristine properties of the system. Thus, understanding the microscopic origin behind the thermal stability of organic/metal interfaces is fundamental for engineering reliable organic-based devices. [...]

Alpha Power and Functional Connectivity in Cognitive Decline: A Systematic Review and Meta-Analysis
Abstract.Background: Mild cognitive impairment (MCI) is a stage between expected age-related cognitive decline and dementia.Dementias have been associated with changes in neural oscillations across the frequency spectrum, including the alpha range.Alpha is the most prominent rhythm in human EEG and is best detected during awake resting state (RS). Though severalstudies measured alpha power and synchronization in MCI, findings have not yet been integrated.Objective: To consolidate findings on power and synchronization of alpha oscillations across stages of cognitive decline.Methods: We included studies published until January 2020 that compared power or functional connectivity between 1)people with MCI and cognitively healthy older adults (OA) or people with a neurodegenerative dementia, and 2) people withprogressive and stable MCI [...]

Emulsion templating: Unexpected morphology of monodisperse macroporous polymers
Hypothesis: We synthesised monodisperse macroporous polymers via polymerisation of water-in-monomer droplet emulsions and obtained non-spherical pores with layered pore walls. We hypothesise that this morphology is caused by surfactant diffusion and phase separation during polymerisation.Experiments: We varied the surfactant mass fraction of the emulsions and polymerised the templates with a water-soluble initiator. [...]

Formulation of Gelled Non-toxic Bicontinuous Microemulsions Stabilized by Highly Efficient Alkanoyl Methylglucamides
Langmuir 36(42), 12692 - 12701 () [10.1021/acs.langmuir.0c02314]
Gelled non-toxic bicontinuous microemulsions have a great potential for transdermal drug delivery as the microemulsion facilitates the solubilization of both hydrophilic and hydrophobic drugs, while the gel network provides mechanical stability and thus an easy application on the skin. In our previous study, we formulated a gelled non-toxic bicontinuous microemulsion: we gelled the system H2O – IPM – Plantacare 1200 UP (C12G1.4) – 1,2-octanediol with the low molecular weight organogelator 1,3:2,4-dibenzylidene-D-sorbitol (DBS).

Discontinuous transition to loop formation in optimal supply networks
The structure and design of optimal supply networks is an important topic in complex networks research. A fundamental trait of natural and man-made networks is the emergence of loops and the trade-off governing their formation: adding redundant edges to supply networks is costly, yet beneficial for resilience. [...]

Impact of edge magnetic perturbation (MP) on multi-scale turbulence and turbulent transport across a MP-induced edge transport reduction in the TEXTOR tokamak
Physics of plasmas 27(6), 062511 - () [10.1063/5.0002022]
Reduced particle losses have been observed during the operation of an m/n = 6/2 resonant magnetic perturbation in the TEXTOR tokamak. The influence of the perturbation field on multi-scale turbulence and turbulent transport has been surveyed in detail across the perturbation-induced reduction of edge transport [...]
