Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Cultivated terraces in Slovenian landscapes

open access: yesActa Geographica Slovenica, 2017
Cultivated terraces distinctively mark the landscape and are a result of human adaptation to steep areas. Terraces were studied with regard to their morphometric qualities, ownership structure, and land use at eight pilot sites in various landscape types

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

open access: yesAdvanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

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.

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 ...

A Swallow's Terrace [PDF]

open access: yesNature, 1890
MR. A. G. VERNON HARCOURT has just shown me, in his boat-house at Cowley Grange, a specimen of swallow's architecture unlike anything I have seen or heard of. The nest, which is itself normal, is placed at the end of a small beam extending from the top of the door to the angle of the building.

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

open access: yesAdvanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

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 ...

Use of terraces to mitigate the impacts of overland flow and erosion on a catchment

open access: yesPlant, Soil and Environment, 2016
The paper presents the impact of a historical system of terraces constructed centuries ago to mitigate the effect of a steep slope on overland flow. Systems of this type were constructed in past centuries by land owners, who then ploughed the land and ...
