A Computational Study of a [2]Rotaxane Molecular Shuttle with All‐Atoms Molecular Dynamics and Density Functional Theory Simulations in Solution

open access: yesChemPhysChem, EarlyView.
A H‐shaped [2]rotaxane is investigated in CH2Cl2 with all‐atoms molecular dynamics simulations combining quantum theory of atoms in molecules (QTAIM) descriptors with density functional theory (DFT) algorithms. Also, the nature of the chemical interactions modulating the formation of a square planar complex following the coordination of a PtCl2 moiety ...

Stratigraphy and development of the Late Miocene-Early Pleistocene Hawke’s Bay forearc basin [PDF]

open access: yes, 2004
A Late Miocene-Early Pleistocene mixed carbonate-siliciclastic sedimentary succession about 2 500 m thick in the Hawke’s Bay forearc basin is the focus of a basin analysis. The area under investigation covers 3 500 km2 of western and central Hawke’s Bay.

Polygonal tepee structures of Arabia

open access: yesThe Depositional Record, EarlyView.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

open access: yesThe Depositional Record, EarlyView.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...

Geologic utility of improved orbital measurement capabilities in reference to non-renewable resources [PDF]

open access: yes
Spectral and spatial characteristics necessary for future orbital remote sensing systems are defined. The conclusions are based on the past decade of experience in exploring for non-renewable resources with reference to data from ground, aircraft, and ...

Unified View of Scaling Laws for River Networks

open access: yes, 2000
Scaling laws that describe the structure of river networks are shown to follow from three simple assumptions. These assumptions are: (1) river networks are structurally self-similar, (2) single channels are self-affine, and (3) overland flow into ...

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, EarlyView.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.
