Chemical dynamics of acidity and heavy metals in a mine water-polluted soil during decontamination using clean water

open access: yes, 2010
A column leaching experiment was conducted to investigate the chemical dynamics of the percolating water and washed soil during decontamination of an acidic mine water-polluted soil.

How phagocytic cells kill bacteria: Lessons from a professional killer

open access: yesFEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Precision estimation of lime requirements in acidic soils using varied soil acidity indices under contrasting application methods in northwest Ethiopia

open access: yesDiscover Environment
Soil acidity is a major constraint to crop productivity in intensively cultivated humid and sub-humid regions worldwide. Accurate estimation of lime requirement (LR) remains challenging due to spatial variability in soil buffering capacity and the use of

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Soil acidity as affecting micronutrients concentration, nitrato reductase enzyme activity and yield in upland rice plants

open access: yesSemina: Ciências Agrárias, 2013
The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity.

Modeling Acidification Recovery on Threatened Ecosystems: Application to the Evaluation of the Gothenburg Protocol in France [PDF]

open access: yes, 2007
To evaluate the acid deposition reduction negotiated for 2010 within the UNECE LRTAP Gothenburg Protocol, sulphur and nitrogen deposition time-series (1880–2100) were compared to critical loads of acidity on five French ecosystems: Massif Central basalt (

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 ...

Long-Term Application of Pig Manure to Ameliorate Soil Acidity in Red Upland

open access: yesAgriculture, 2023
While the application of manure to improve soil quality has attracted attention, the effect of pig manure application rates on soil acidity remains poorly understood. In this study, we analyzed the changes and correlations between soil acidity, pH buffer

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.

Soil Erosion: Types and Their Mechanism

open access: yesInternational Journal of Economic Plants, 2015
Soil erosion is a universal phenomenon. Out of the 328.7 m ha of India’s geographical area about 175 m ha (53.3%) is subjected to soil erosion and some kind of land degradation.
