Electrochemical characterization of mangrove sediments: A proposal of new proxies for organic matter oxidation
(Elsevier, 2019)
The voltammetric response of microparticulate deposits resulting from solvent evaporation of ethanolic extracts of mangrove sediments in contact with aqueous acetate buffer is hereby described. Dated sediment cores sampled ...
Organic matter-phosphorus associations as a sink in P-fixation processes in allophanic soils of Chile
(Pergamon Press Ltd, 1983)
In fertilized and unfertilized plots of ten Chilean allophanic soils the fraction of total-P associated with organic matter and the organic carbon content were determined. Cultivation with P fertilization for 40 yr or ...
Leaking elastic capacitor as model for active matter
(2021-05-24)
We introduce the “leaking elastic capacitor” (LEC) model, a nonconservative dynamical system that combines simple electrical and mechanical degrees of freedom. We show that an LEC connected to an external voltage source ...
Determination of mercury methylation potential in the presence of peat organic matter
(2013-08-01)
Methylmercury (MeHg) is a neurotoxin pollutant that accumulates in organisms and biomagnifies along the trophic chain. It is formed by the transfer of a methyl group to inorganic mercury (Hg). This transformation, termed ...
Characterization of the dissolved organic matter present in the water of the Bío-Bío river, VIII Region of Chile
(Sociedad Chilena Química, 2016)
The dissolved organic matter in rivers has different origin and its composition can vary both by natural conditions and the anthropic activity that takes place near rivers. This mobile fraction of the organic matter is ...
Are active organic matter fractions suitable indices of management effects on soil carbon? A meta-analysis of data from the Pampas
(Taylor & Francis, 2016-03)
Active fractions of organic matter have been proposed as early indices of changes in soil organic carbon (organic-C) induced by management. We performed a meta-analysis of published results from 31 field experiments conducted ...
Equilibrium to off-equilibrium crossover in homogeneous active matter
