Long-term Effects of Tillage on the Retention and Transport of Soil Water [PDF]

open access: yes, 1986
Quantitative measurements were made of the physical and chemical properties of two virgin prairie soils, Crowley and Jay, that remain in their native Arkansas environments and of similar soils that had been tilled extensively.

Empirical rainfall thresholds for mudflow events in an arid basin of the Peruvian coast

open access: yesFrontiers in Water
Mudflows, a highly destructive natural phenomenon, frequently occurs in arid regions due to the activation of basins by extreme climate events. In Peru, the Pacific coastal basin and steep regions is particularly vulnerable to these events, which have ...

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

open access: yesAdvanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.
