Ambiguities in Assigning Single‐Crystal NMR Data to Individual Atoms in the Crystal Structure: A Case Study of Hambergite, Be2BO3OH, by 9Be and 11B NMR Spectroscopy, XRD Measurements and DFT Calculations

Magnetic Resonance in Chemistry, Volume 64, Issue 4, Page 400-415, April 2026.
The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9Be and 11B of hambergite, Be 2BO 3OH, were derived from single‐crystal NMR experiments.

Novel Behaviors to the Nonlinear Evolution Equation Describing the Dynamics of Ionic Currents along Microtubules

ITM Web of Conferences, 2017
In this work, we consider the Bernoulli sub-equation function method for obtaining novel behaviors to the nonlinear evolution equation describing the dynamics of ionic currents along Microtubules. We obtain new results by using this technique.

Zwischen Ordnung und Verwirrung: Missverständnisse in der Nomenklatur von Kohlenstoffmaterialien

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Trotz der vielfältigen Einsatzmöglichkeiten von Kohlenstoffmaterialien führen uneinheitliche Terminologie und unzureichende Charakterisierung – insbesondere im Hinblick auf die Ordnung der zugrunde liegenden Graphenen – häufig zu Fehlinterpretationen. Der Artikel klärt Begriffe wie Graphit, graphitischer Kohlenstoff, nicht‐graphitischer Kohlenstoff und

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

A Symbolic Algorithm for Checking the Identifiability of a Time-Series Model

Information
Several authors have attempted to compute the asymptotic Fisher information matrix for a univariate or multivariate time-series model to check for its identifiability. This has the form of a contour integral of a matrix of rational functions.
