Anisotropic Hierarchical Assembly of C60 from One Dimensional to Three Dimensional via Thiolate‐Mediated van der Waals Epitaxy

open access: yesSmall Structures, EarlyView.
This work shows a thiolate‐mediated van der Waals epitaxial strategy that enables the growth of anisotropic C60 structures with tunable dimensionality on Au(111). By employing pentanethiol as a cohost species, we achieve precise structural control, yielding architectures from 1D C60 nanochains to 3D superstructures possessing an orthorhombic lattice ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

open access: yesStructural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

open access: yesTAXON, EarlyView.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Modelling the surprising recolonisation of an understudied aquatic mammal in a highly urbanised area: fortune favoured the smooth‐coated otter in Singapore

open access: yesWildlife Biology, EarlyView.
Ever‐growing human activities present an active and continuing threat to many species throughout the world. Nevertheless, concerted conservation efforts in some regions have balanced these threats and allowed endangered species to recolonise former parts of their original ranges and reverse their decline.
