Possibilities of some methods for risk assessment of arsenic load in soils
Plant, Soil and Environment, 2008 The paper deals with the possibilities of arsenic analysis in the soil. The aim is the selection and verification of the methods for analysis of As in the soil, which seem to be suitable for risk evaluation based on the increased As soil load. Economical

Nanoscale soil-water retention mechanism of unsaturated clay via MD and machine learning [PDF]
arXiv, 2021 In this article, we investigate the nanoscale soil-water retention mechanism of unsaturated clay through molecular dynamics and machine learning. Pyrophyllite was chosen due to its stable structure and as the precursor of other 2:1 clay minerals. A series of molecular dynamics simulations of clay at low degrees of saturation were conducted.

Eos, Transactions American Geophysical Union, 1976 Water has been called ubiquitous, which may be a small exaggeration, but it is no exaggeration to say that it is intimately associated with soil. In the never‐ending hydrologic cycle, rain falls upon the soil, and whether the soil is shielded by vegetation or otherwise protected is much of what soil and water conservation is all about.The story of soil

Advanced Functional Materials, EarlyView.This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

Vibration-Induced Conductivity Fluctuation Measurement for Soil Bulk Density Analysis [PDF]
, 2007 Soil bulk density affects water storage, water and nutrient movement, and plant root activity in the soil profile. Its measurement is difficult in field conditions. Vibration-induced conductivity fluctuation was investigated to quantify soil bulk density with possible field applications in the future. The AC electrical conductivity of soil was measured

Advanced Functional Materials, EarlyView.Ambient‐dried composite aerogels integrating MOF‐303, TEMPO‐oxidized cellulose nanofibers (TOCNF), and hygroscopic salts enable high‐performance atmospheric water harvesting (AWH), achieving competitive uptake at both low and high humidity. Enhanced with a solar‐evaporation layer, these scalable aerogels support self‐sustained plant growth in a ...

Dark oxidation of water in soils [PDF]
Tellus B: Chemical and Physical Meteorology, 2013 We report the release of oxygen (O2) under dark conditions in aerobic soils. This unexpected process is hidden by respiration which constitutes the dominating reversal O2 flux. By using H218O in different soils, we confirmed that 16O18O and 18O2 released under dark soil conditions originated from added H218O.
