Assessment of Impact on Landscape Development to Ecological Service Values and Goods Using Integrated Remote Sensing and GIS Techniques [PDF]

open access: yes, 2005
Amongst the impacts of converting forest to agricultural activities is the degradation of ecology service values and goods (ESVG). Impacts on ESVG can be devastating in environmental, biological, and socio-economics manners.

Reservoir theory for studying the geochemical evolution of soils [PDF]

open access: yes, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

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

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Effects of Maize Residue Biochar Amendments on Soil Properties and Soil Loss on Acidic Hutton Soil

open access: yesAgronomy, 2018
Soil acidification is a serious challenge and a major cause of declining soil and crop productivity in the Eastern parts of South Africa (SA). An incubation experiment investigated effects of different maize residue biochar rates on selected soil ...

Highly Sensitive Oxidation‐Resistant Degradable Janus Piezoresistive Electronic Skin for Sustainable Wearable Electronics

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a highly sensitive, oxidation‐resistant, biocompatible, and degradable Janus piezoresistive electronic skin for sustainable wearable electronics. The electronic skin exhibits sensitive and stable response across a broad pressure range, exceptional oxidation resistance, and Janus wettability.

Conversion of agricultural soils in Austria—a case study for a community in Upper Austria

open access: yesDie Bodenkultur, 2020
We have analyzed the loss of agricultural land in a case study of the community Eggelsberg in the Innviertel in Upper Austria. The trigger for the project was the attribution of Austria as Europe’s leader in soil sealing.

Proximate controls on semiarid soil greenhouse gas fluxes across 3 million years of soil development [PDF]

open access: yes, 2015
Soils are important sources and sinks of three greenhouse gases (GHGs): carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). However, it is unknown whether semiarid landscapes are important contributors to global fluxes of these gases, partly ...

Agricultural carbon sequestration, poverty, and sustainability [PDF]

open access: yes, 2008
This paper explores the potential impacts of payments for agricultural soil carbon sequestration on poverty of farm households and on the sustainability of agricultural systems, using economic theory combined with evidence from three case studies in ...
