Ladderization: A Powerful Strategy for Controlling Supramolecular Helical Ordering, Amplifying Asymmetry, and Emerging and Enhancing Circularly Polarized Luminescence

open access: yesSmall, EarlyView.
π‐Conjugated chiral ladder polymers with enantiopure side groups exhibit helical ordering‐induced circularly polarized luminescence (CPL) in poor solvents and in the film state. Vapor‐annealed films show a particularly strong CPL with glum values of > 0.1. Blending chiral/achiral ladder polymers markedly amplifies the asymmetry in the film.

Liquid Crystal Polymers as Intrinsically Magnetic and Programmable Soft Materials for Microrobotics

open access: yesSmall, EarlyView.
Liquid crystal polymers (LCPs) are proposed as intrinsically magnetic, programmable, soft materials for microrobotics. Magnetic torque‐driven manipulation of LCP microobjects is achieved and characterized in terms of the step‐out frequency, reaching ∼0.6 Hz in a ∼250 mT magnetic field. The orientation of LCP microobjects in the magnetic field and their

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 ...

Shared and specific molecular mechanisms of proteasome inhibitors in chemotherapy‐induced peripheral neurotoxicity

open access: yesBritish Journal of Pharmacology, EarlyView.
This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

Uncertainty‐Aware Visual Analysis of Force Networks in 2D Granular Materials

open access: yesComputer Graphics Forum, EarlyView.
Abstract Uncertainty in experimental measurements makes it challenging to determine which features are intrinsic to the phenomenon and which are most stable and reliable. Granular materials, such as sand, form a complex system in which the forces between individual particles influence the material's macroscopic behavior.

Comparison of Long vs. Short Concave Neck in One‐Piece Implants Inserted 1 mm Subcrestally: A Pre‐Clinical In Vivo Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives The aim was to assess the influence of one‐piece implant concave neck height on soft‐ and hard‐tissue healing on a canine model. Material and Methods Monoblock implants with a transgingival concave neck were randomly inserted 1 mm subcrestally.

Compatibility of personal care thickening polymers in sulphate‐free surfactants

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘
