Chronology of fans and terraces in the Galatea Basin

open access: yes, 1968
Air-borne volcanic ash beds are used to date fans and terraces in the Galatea Basin and to outline the depositional history of this part of the Rangitaiki Valley.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

open access: yesAdvanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Ecotourism as a Means of Conservation of the Landscape of Rodrigues Island

open access: yesMiscellanea Geographica: Regional Studies on Development, 2015
The Indian Ocean island of Rodrigues provides an interesting landscape case study. It offers a characteristic example of a small island territory whose natural and environmental resources have been overexploited by human activity and whose inhabitants ...

Drainage network development in the Pannonian Basin

open access: yesHungarian Geographical Bulletin, 2015
The evolution and development of the greatest rivers in the Pannonian Basin have been investigated for almost 150 years. At the end of the Late Miocene Sub-Epoch (7.5-5.3 Ma BP) and at the beginning of Pliocene Epoch (5.3-4.5 Ma BP) Lake Pannon shrank ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Topography and Substrate Lithology Control the Position of Fluvial Channels on a Drained Lake Floor, the Case of the Postglacial Ain Valley (Eastern France)

open access: yesQuaternary
The development of fluvial systems over long time scales is a complex interplay of tectonic, climatic, and lithological factors. The initiation and location of fluvial channels in the landscape is less well understood.

The Origins of Terracing in the Southern Levant and Patch Cultivation/Box Fields

open access: yesJournal of Landscape Ecology, 2017
This paper looks at various suggestions relating to what incipient and early forms of terracing might have looked like, and goes on to suggest that some of the earliest terraces in the southern Levant may have emerged from horticultural practices, and ...

Marine-planation terraces on the shelf around Grand Cayman: a result of stepped Holocene sea-level rise

open access: yes, 1995
The shelf around Grand Cayman consists of two seaward-sloping terraces separated by a mid-shelf scarp . Except along the exposed windward margin where coral growth is dominant, the upper terrace (0-10 m bal) largely consists of a barren rocky pavement ...

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.
