A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling

open access: yesChemistry – A European Journal, EarlyView.
A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

A Seismic Inversion Problem for an Anisotropic, Inhomogeneous Medium [PDF]

open access: yes, 2002
In this report, we consider the propagation of seismic waves through a medium that can be subdivided into of two distinct parts. The upper part is assumed to be azimuthally symmetric, linearly nonuniform with increasing depth, and the velocity dependence

Internationalising the teacher education curriculum: An analysis of syllabi and student experiences

open access: yesThe Curriculum Journal, EarlyView.
Abstract Internationalisation has increasingly become a key dimension of quality in initial teacher education (ITE) programmes. Although it is recognised as a means to strengthen future teachers' competencies and expand their professional knowledge, it remains underdeveloped in practice.

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.
