Nanomaterials in Surface Water and Sediments: Fate and Analytical Challenges
(American Society of Civil Engineers, 2016-01)
Nanomaterials (NMs) present some interesting properties that may be tailored; for this reason, they are being used in different fields, which leads to their entry into the environment, whether by normal use or intentional ...
Intertechnique comparisons for nanoparticle size measurements and shape distribution
(American Society of Civil Engineers, 2016-01)
There are a number of techniques for measuring and characterization of nanoparticle (NP) size. One of the main problems in the field of NP analysis is in producing reliable and reproducible characterization data for ...
Análisis de sensibilidad espacial de un modelo hidrodinámico del embalse Punchiná (Antioquia)
(Fondo Editorial EIA, 2013-12-17)
This paper presents a methodology to assess explicitly the optimal value of the numerical parameters in a hydrodynamic model, such as the grid resolution (horizontal and vertical direction) and the calculation time interval. ...
