Multifractal analysis of discretized X-ray CT images for the characterization of soil macropore structures [PDF]

open access: yes, 2010
A correct statistical model of soil pore structure can be critical for understanding flow and transport processes in soils, and creating synthetic soil pore spaces for hypothetical and model testing, and evaluating similarity of pore spaces of different ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Release of high-molecular-weight plasticizers from PVC: mesocosm experiments under near-natural conditions

open access: yesEnvironmental Sciences Europe
Background In recent years, rapidly increasing environmental concentrations have been observed for certain high-molecular-weight (HMW) plasticizers, that are mainly used in PVC outdoor products.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Comparative response on the growth of the tomato (Lycopersicon esculentum) under fertilizer treatment based on on-site soil testing

open access: yesEnvironment Conservation Journal, 2017
With the ever increasing demand for increasing the productivity per unit area and the narrowing cost benefit ratio has made the farmer more sensitive to the soil fertility status and soil health.

Shear Strength Properties of Coarse-Grained Soils Determined Using Large-Size Direct Shear Test

open access: yesCivil and Environmental Engineering, 2022
The paper deals with an analysis of the shear strength behaviour of coarse-grained materials using large-sized direct shear apparatus. The shear strength curve of compacted coarse-grained material allows for determining the three typical shear strengths,
