Optical response of WSe2-based vertical tunneling junction
No full textLayered materials have attracted significant interest because of their unique properties. Van derWaals heterostructures based on transition-metal dichalcogenides have been extensively studied because of potential optoelectronic applications. We investigate the optical response of a light-emitting tunneling structure based on a WSe2 monolayer as an active emission material using the photoluminescence (PL) and electroluminescence (EL) experiments performed at low temperature of 5 K. We found that the application of the bias voltage allows us to change both a sign and a value of free carriers concentrations. Consequently, we address the several excitonic complexes emerging in PL spectra under applied bias voltage. The EL signal was also detected and ascribed to the emission in a high-carrier-concentration regime. The results show that the excitation mechanisms in the PL and EL are different, resulting in various emissions in both types of experimental techniques.</p

It is named after the lineage of Bönpo priests in whose house it is kept. The collection, consisting of 340 different items with a total of 3,477 folios, cards, or individual sheets of paper, represents the ritual repertoire of the priests of the kings of Mustang, once a Tibetan kingdom and now a district of Nepal. The manuscripts exemplify the variety of forms, scripts, decorations, materials and other codicological features. The texts have not been used since the priestly line ended in the 1950s or 60s. The value of this collection is twofold: first, the collection was assembled from different parts of Tibet and the Himalaya over six centuries, and offers a rich body of material which can be retrieved by material and codicological analyses that will contribute to our understanding of book and paper making traditions in the region, as well as social aspects of Tibetan manuscript production; and secondly, in terms of its content, it offers a window onto the nature of royal religion in a Tibetan kingdom. These manuscripts were used in rituals for the protection and prosperity of the kingdom of Mustang, its subjects and members of royal lineage; knowledge of the materials and ritual practices involved in the creation of physical objects will help to understand the interaction between religion, patronage and political authority in Tibetan society.DATASET FILESThe dataset contains files:• Drangsong_116.zip (master scans of the manuscript pages with color checker),• Drangsong_116.pdf (containing presentation images of the manuscript pages),• Drangsong_116_001v.png (manuscript page sample),• Drangsong_116_backlites.zip (backlit samples),• Drangsong_116_macros.zip (in close-up samples),• Drangsong_116_XRF_analysis.png (X-ray fluorescence spectrometry).DESCRIPTION OF THE MANUSCRIPTDetailed information on writing, materials, format, and layout is provided in a Readme.txt file attached to this dataset.</p

Fungal non-pollen palynomorphs (fNPPs) from moss samples in Białowieża Forest
No full textThe dataset contains raw counts of fungal non-pollen palynomorphs (fNPPs) identified in modern moss polsters collected in Białowieża Forest ecosystems. These counts are provided per sample and represent the absolute numbers of spores observed under a microscope before any transformation or normalization. The dataset supports studies on fungal diversity, ecological interactions, and the use of fungal NPPs as proxies in paleoecological reconstructions.The project aims to determine the composition of fungal non-pollen palynomorphs (fNPPs) in modern pollen samples from the Białowieża Forest and to examine how environmental factors such as vegetation type, landscape openness, herbivore pressure, wetness, and presence of deadwood influence their abundance and diversity. The established relationships may enhance our understanding of the indicative value of fungal NPPs for reconstructing historical environmental conditions, providing critical insights into past forest dynamics and herbivory patterns.To achieve these goals, moss samples, which act as natural pollen traps, were collected in 2021 across different habitats within the Białowieża Forest. Samples were processed using standard palynological methods, and fNPPs were identified and counted under a light microscope. The observations suggest that fungal NPP composition varies significantly with environmental gradients, highlighting their potential as indicators of ecological and historical processes.</p

Research data for article 'To be or not to be polar: the ferroelectric and antiferroelectric nematic phases'
No full textWe have reported two new series of compounds, nEC6F and nOEC3F, that show the ferroelectric nematic, NF, phase. We have determined that elongation of the terminal chain weakens the dipole-dipole interactions of the molecules along the director and thus lowers the temperature at which the axially polar NF phase is formed. For homologues of intermediate chain lengths, between the non-polar and ferroelectric nematic phases, another nematic phase emerges, Nx, having antiferroelectric character. The size of the antiparallel ferroelectric domains in Nx phase critically increases upon transition to the NF phase. In dielectric studies, both collective (‘ferroelectric’) and non-collective fluctuations are present, the ‘ferroelectric’ mode softens weakly at the N-NX phase transition because the polar order in this phase is weak. The transition to the NF phase is characterized by a much stronger lowering of the mode relaxation frequency and an increase in its strength, typical critical behaviour is observed.The dataset includes:1) publication in ACS Omega (manuscript and Supporting Information, pdf format ) - see also https://doi.org/10.1021/acsomega.3c058842) numerical data (ASCI) for optical birefringence measured vs. temperature for selected compounds3) numerical data (ASCI) for dielectric permittivity measured vs. temperature and frequency for selected compounds4) numerical data (ASCI) for periodicities determined by X-ray diffraction (XRD) and Resonant Soft X-ray Scattering (RSoXS) for selected compounds5) Raw data for XRD and RSoXS experiments (2D detector images, in edf and fits formats)</p
