Theoretical study of geometries and 1H-chemical shifts of cycloarenes

, 1985
The geometries of the cycloarenes 1–6 with 9–12 annelated benzene rings are determined by means of a π-SCF force-field approach. 1H-chemical shifts are calculated by taking into account ring current and local anisotropic contributions.

2D Laminated Hybrid Architectures Based on Graphene/Mesoporous Polyaniline for High‐Performance Supercapacitor Electrode

Small, EarlyView.
We demonstrate a rational and scalable strategy for the construction of 2D hybrid architecture by the liquid‐phase co‐assembly of graphene and polyaniline nanosheets. A high‐shear mixing process enables face‐to‐face stacking, creating a robust interface with strong electronic coupling.

A parallel algorithm for the enumeration of benzenoid hydrocarbons

, 2009
We present an improved parallel algorithm for the enumeration of fixed benzenoids B_h containing h hexagonal cells. We can thus extend the enumeration of B_h from the previous best h=35 up to h=50.

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Isolation and X-ray Structures of Labile Benzoic- and Acetic-Acidium Carbocations [PDF]

, 2005
New carbocationic salts (via O-protonation of substituted benzoic acids) are prepared for the first time by controlled hydration of the corresponding benzoylium salts and isolated in pure crystalline form.

Pollinator diversity and host specificity in threatened Encephalartos cycads and their implications for co‐extinction and species recovery

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.
