The mobility of ions under confinement in nanoporous materials is central to many electrochemical energy transformation and storage devices. By using ionic liquids (ILs) and metal-organic frameworks (MOFs) as well-defined, regular nanoporous host, the dynamic ion properties are explored in detail. Here, we demonstrate that applying a gate-voltage allows to considerably enhance the ion mobility. The experiments based on MOF films show a conductivity increase of up to 35%. Molecular dynamic simulations show that the gate-voltage-field causes layers of increased and decreased ion concentrations, parallel to the charge transfer direction. In these layers, the ion mobility can be up to 2.5 times larger than in the bulk phase or without an additional gate-voltage field. Thus, these layers of highly-mobile ions resemble gate-voltage-induced ion highways, causing the experimentally observed higher conductance. The study provides deeper insights into ion dynamics in nanopores, provides a method for enhanced ion mobilities and may help designing advanced electrochemical devices with improved dynamics and larger power-output.

This dataset presents the primary archaeological documentation from excavation work conducted at Amarna Site M50.14–16, located in the Main City South at Amarna (ancient Akhetaten, Middle Egypt, 18th Dynasty, c. 1353–1336 BCE). The material derives principally from the 2014 and 2017 field seasons and subsequent study seasons and comprises stratigraphic records, context sheets, archaeological plans, spatial data, photographic documentation, finds catalogues, and associated analytical results. The site consists of two domestic structures and an adjoining courtyard forming part of a densely occupied urban quarter of the 18th Dynasty capital. Excavation revealed evidence for integrated domestic and craft activities, including glass- and faience-working, metal processing, and associated high-temperature installations. The dataset includes detailed artefact inventories (ceramic, vitreous, metal, stone, and small finds), archaeobotanical and zooarchaeological data where available, and compositional analyses of selected materials. All records are presented in structured digital formats to facilitate reuse, comparative research, and integration with broader datasets relating to urban production and household economy at Amarna. The archive is intended to support transparency, reproducibility, and future analytical work on craft production, spatial organisation, and socio-economic practices within the short-lived capital founded by Akhenaten.

Bottlenecks – a severe reduction in population size—are ubiquitous for bacteria in natural systems. For example, during the complete metamorphosis of insects, the gut microbiota is bottlenecked due to a massive secretion of immune effectors such as antimicrobial peptides (AMPs) into the gut. However, the effect of natural bottlenecks on the resistance evolution of bacteria to AMPs is currently unknown. Here, we measured the bottlenecking of the gut microbiota of G. mellonella, the greater wax moth. Based on the bottleneck size in gut microbiota, we then tested in vitro the influence of bottleneck size on the adaptation of E. coli against an AMP. We used wild-type E. coli and mutator strains with a 100-fold increase in mutation rates to partly disentangle population size from mutant supply. We found that large E. coli mutator strain populations evolved higher resistance than small populations. Population size, however, did not affect adaptation in wild-type strains. They could not evolve resistance under our experimental conditions. This shows that natural bottlenecks can benefit insect hosts by combating the evolution of AMP resistance to their resident gut microbiota. This should also be applicable to infections in other organisms that use AMPs as an immune defense.

Large low shear velocity provinces have been observed beneath Africa and the Pacific. These large-scale structures are considered to have been stable the last hundred million years with their origin and nature still being an open question. In our 2D Cartesian study, we numerically investigate the temporal and spatial stability of thermochemical piles. We consider two different scenarios, in which the piles either arise from a primordial layer above the core-mantle boundary (CMB) or from an influx of iron-rich material through the CMB. The investigated mantle flow depends on viscosity varying with composition, depth, and stress. The rheological parameters affect the strength of convection and consequently the stability of piles. An increased top or bottom viscosity reduces the convective vigor yielding longer-lived and more stable piles. Likewise, a thermal expansivity decreasing with depth exhibits longer pile lifetimes and less pile movement. Furthermore, piles and plumes are two closely linked structures. While thermochemical plumes are anchored by piles, thermal plumes attract piles and deform them. Long-lived plumes tend to be located in the center of piles, but during dynamical processes, such as merging of piles, plumes also occur at the edges remaining there for several million years. In summary, we suggest that the LLSVPs might have formed early after the magma ocean, probably as several initially thin structures due to strong convection in the hot Archean mantle. With the cooling of the mantle, the structures would have broadened and stabilized in space and time, yielding the present-day state.

The mosaic comprises four HiRISE (High Resolution Imaging Science Experiment, McEwen et al., 2007) images: ESP_035141_1990_RED, ESP_037330_1990_RED, ESP_037607_1990_RED and PSP_002743_1985_RED. Individual images were co-registered to a single CTX (Context Camera) ortho-image scene G12_022957_1985_XN_18N282W (5 m/pixel) (Malin et al., 2007), which was itself co-registered to the HRSC Mars Chart (HMC_13E10) ortho-rectified image mosaic (12.5 m/pixel) (Gwinner et al., 2016). Co-registration was performed using the “Georeferencing” tool in ArcGIS software with manually selected control points and spline transformations. Following co-registration, brightness normalization was applied to harmonize the individual HiRISE images with the reference CTX image, thereby eliminating albedo discontinuities at image boundaries and achieving a visually homogeneous mosaic. Each HiRISE scene was subdivided into a grid of 12 × 36 patches (x-direction × y-direction), and the average brightness was calculated for each patch along with the corresponding patch from the reference CTX image. A normalization ratio for each patch was computed by dividing the reference brightness value by the original image brightness value. Transitions between patches were interpolated to eliminate visible boundary effects. Finally, the normalized images were mosaicked using standard GDAL command-line tools. The brightness adjustment algorithm was implemented in Python.

t has become commonplace for non-democratic regimes to integrate information and communication technologies (ICTs) into their governance system. However, how citizens make use of these new digital opportunities in an authoritarian setting remains understudied. Based on an online survey in China in 2021, we find that a surprisingly large share of Chinese citizens engages with the new ICT-based participatory venues. But ICTs seem to unfold their potential only for certain groups such as tech-savvy younger citizens with a higher income. Moreover, while citizens seem to be quite aware of the risks of using ICTs, such as data security breaches or digital surveillance, these do not seem to hamper participation. Rather, citizens trade off perceived risks for perceived benefits, such as higher levels of convenience, efficiency, or expected government responsiveness. Our study contributes to the literature on digital governance in authoritarian regimes, and the digital divide and technology acceptance literatures. Moreover, amid the tightening of political control in China, it offers insights into participatory developments under Xi Jinping.

In the design of nanoscale materials, hybrid van der Waals heterostructures that integrate the excitonic landscape of atomically thin transition metal dichalcogenide (TMDC) semiconductors with molecular electric dipoles offer enhanced control over light–matter interactions and charge carrier dynamics. Even minor deviations in homogeneity can profoundly affect their optoelectronic properties and, consequently, device performance, necessitating stringent quality control capable of probing structural and compositional divergences down to the nanoscale. However, the reliable characterization of such complex, multilayered systems remains challenging due to the interplay of chemical, structural, and optical inhomogeneities across different length scales. In this study, we examine a trilayer heterostructure consisting of chemical vapor deposition (CVD) graphene (G), a self-assembled layer of Rhodamine 6G (R6G), and a transferred monolayer MoS₂ (G/R6G/MoS₂), incorporating regions of a tri- and multilayer MoS₂ as well. Comprehensive structural and optical characterization was performed to identify possible inhomogeneities, employing photoluminescence (PL) spectroscopy, Raman spectroscopy, Kelvin probe force microscopy (KPFM), and scattering-type scanning near-field optical microscopy (s-SNOM). Analytical methods indicate that the TMDC layer has almost uniform molecular coverage and preserved crystallinity. Importantly, near-field optical imaging demonstrates the propagation of exciton-polaritons in MoS₂, with a clear redshift of the polariton wavelength upon R6G integration, signifying substantial modulation of the local dielectric environment and excitonic response. These findings underscore the tunability of hybrid 2D molecular–inorganic interfaces and their promise for advanced applications in nanophotonic devices, excitonic circuitry, and quantum optoelectronics.

This data set is the result of the route reconstruction of the German expedition to East Africa in 1861/1862. The expedition was led by Werner Munzinger, and the section covered here led from Mai Scheka in present-day Eritrea through Tigray in Ethiopia to Kassala in Sudan. The reconstruction was based on the maps and reports published by the expedition team:

Heuglin, T. v., Kinzelbach, T., Munzinger, W., and Steudner, H.: Die Deutsche Expedition in Ost-Afrika 1861 und 1862: Zusammenstellung der astronomischen, hypsometrischen und meteorologischen Beobachtungen, und der trigonometrischen und itinerarischen Aufnahmen, Mittheilungen aus Justus Perthes' Geographischer Anstalt über wichtige neue Erforschungen auf dem Gesammtgebiete der Geographie; 13 = Ergänzungsband III, Perthes, Gotha, 46 pp., 1864.

We gathered all geospatial information from these sources to reconstruct the route on a modern map basis. All methodological details can be found in the accompanying research paper.

Here we publish three files in the shapefile format:

1. munzinger_pois_reconstructed.shp (point shapefile) These are the places of interest that we extracted from Munzinger's maps and travel reports and located on a modern basis. These are differentiated in -stop: locations where the group stayed over night -poi: places of interest the group used for orientation or provided information about -wp: waypoints that the group passed by -torrent: streams/valleys that the group hat to cross

2. munzinger_stations_reconstructed.shp (point shapefile) These are all of the geodetic measurement stations that the group set up. The attribute table contains: -station: the name of the station as on the maps -dir_text: the direction as given in the text, including cardinal direction -location: the place on which the measurement was focused -deviation: the magnetic deviation of the angular measurements as stated in the text -dir_dev360: The angular measurement converted to 360 degree space including the magnetic deviation --> these are the final values we used for the reconstruction

3. munzinger_route_reconstructed.shp (line shapefile) This is the final reconstructed route.

All files are in EPSG:32637 - WGS 84 / UTM zone 37N

This dataset contains two sets of Mars atmospheric dust scenarios based on the daily maps of the column dust optical depth (CDOD) from Montabone et al. (2015, 2020). The first set contains 7 artificial dust scenarios with shifted timings of the Mars Year 25 global dust event (Ls=150° to Ls=330°, in steps of 30° of Ls). The second set contains dust scenarios for Mars Years 29 to 33, with additional storms shapes from the Mars Dust Storm Sequence Database (Saidel et al., 2022). For the MDSSD storms, a homogeneous storm CDOD of 0.6 (at 9.3 µm) was assumed. All these scenarios can be used to model the dust cycle in the LMD Mars Planetary Climate Model.

We report on the first push-pull quino [3]radialene fluorescent dye. Here, the novel bis(dicyanomethylene)-[3]radialene electron acceptor was connected to a benzimidazole donor. With protonation a substantial red-shift of fluorescence wavelength is observed, while the absorption maximum remains stable. This process is accompanied with an increased fluorescence quantum yield to about 70%. Further, we explain the findings by a combined experimental and theoretical approach and find that vibronic coupling plays a crucial role. This study highlights the yet unexplored potential of [3]radialene-based motifs for the design of environment-responsive fluorophores.
