Multitemporal dendrogeomorphological analysis of slope instability in Upper Orcia Valley (Southern Tuscany, Italy) [PDF]

open access: yes, 2016
The Upper Orcia Valley (Southern Tuscany, Italy) is a key site for the comprehension of denudation processes typically acting in Mediterranean badlands (calanchi) areas, thanks to the availability of long-lasting erosion monitoring datasets and the ...

Impact of Textile Architecture on the Electromechanical Behavior of Conductive Carbon: Silicone Composite Strain Sensors

open access: yesAdvanced Engineering Materials, EarlyView.
A stretchable carbon composite is integrated by stencil printing onto two different types of textile, with different yarn morphologies. The impact of the knit structure and coating direction on the performance of the sensor composite is evaluated and used to derive a model estimating nominal resistance at a given strain near the percolation threshold ...

Impact of atmospheric ammonia on growth, C and N accumulation and photosynthesis of two maize cultivars with different N root supply

open access: yesPlant, Soil and Environment, 2011
Impact of enriched atmospheric NH3 in combination with low and high N medium on growth, total C and N accumulation (CtotA and NtotA) and photosynthetic characteristics of two maize cultivars i.e. SD19 (cult. 1) and NE5 (cult. 2) with low N and N high use

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

open access: yesAdvanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

The relationships and sensibility of wheat C:N:P stoichiometry and water use efficiency under nitrogen fertilization

open access: yesPlant, Soil and Environment, 2015
A field study was conducted to investigate the variations in the carbon:nitrogen:phosphorus (C:N:P) stoichiometry of winter wheat (Triticum aestivum L.) and its relationships with wheat growth rate (r) and water use efficiency (WUE) under different rates

Preferential flow of surface‐applied solutes: Effect of lysimeter design and initial soil water content

open access: yesVadose Zone Journal, 2020
Undisturbed lysimeters are widely used to study water and solute transport, where both natural and unnatural preferential flow can greatly influence leaching rates.

Scale-free channeling patterns near the onset of erosion of sheared granular beds

open access: yes, 2016
Erosion shapes our landscape and occurs when a sufficient shear stress is exerted by a fluid on a sedimented layer. What controls erosion at a microscopic level remains debated, especially near the threshold forcing where it stops.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Estimating Percent Residue Cover Using the Line-Transect Method [PDF]

open access: yes, 2009
Leaving crop residue on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
