2D and 3D Nets by Self‐Assembly of Carbosilane Functionalized Polyphilic Liquid Crystals

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
In the shown compounds, the growing volume of the carbosilane side‐groups modifies the self‐assembly in liquid crystalline phases ranging from a square via a pentagonal to a hexagonal honeycomb and finally to a 3D (10,3)‐a double net. The structures are discussed in relation to inorganic solid‐state materials and the concept of “mesoatoms”.

High‐purity X‐ray polarimetry at high energies for Mössbauer spectroscopy

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work extends high‐purity X‐ray polarimetry into the 15–30 keV range, enabling polarization‐filtered synchrotron Mössbauer spectroscopy of higher‐energy nuclear resonances. A proof‐of‐principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10−8, establishing the feasibility of the approach.High‐purity X‐ray ...

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...
