High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Crystal Chemistry of Boron and of Some Boron-Rich Phases; Preparation of Boron Modifications

open access: yes, 1977
For many years, most physico-chemical studies of boron and its compounds were made with elemental boron which was of low purity and usually amorphous or at least very poorly crystallized. Such a type of boron was generally obtained either by reduction of a boron compound using a highly electropositive metal (reduction of B2O3by magnesium or of KBF4 by ...

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

open access: yesAdvanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Worth of boron rod in the reactor MOATA.

open access: yes, 1967
The U235 fuel increase required to compensate for the insertion in MOATA of an enriched boron rod is measured. The DIFF code is used to calculate the mass increase and comparison with the experimental result provides a check on the theory incorporated in
