Long-term field metal extraction by pelargonium:phytoextraction efficiency in relation to plant maturity [PDF]
, 2011 The long length of periods required for effective soil remediation via phytoextraction constitutes a weak point that reduces its industrial use. However, these calculated periods are mainly based on short-term and/or hydroponic controlled experiments ...

Functionalized sepiolite for heavy metal ions adsorption
Desalination, 2008 Abstract Surface modification of clays has become increasingly important due to the practical applications of clays such as fillers and adsorbents. The surface modification of sepiolite with [3-(2-aminoethylamino)propyl]trimethoxysilane has been employed. The modified sepiolite surface was investigated by FTIR, XRD and DTA/TG analysis.

Identification and functional analysis of two ZIP metal transporters of the hyperaccumulator Thlaspi caerulescens [PDF]
, 2009 The heavy metal hyperaccumulator Thlaspi caerulescens expresses several ZIP-like genes at higher levels than their orthologues in non-hyperaccumulator species, but it is not clear why. To elucidate the function of the T.

Heavy Molecular and Metallic Ions in the Magnetosphere
Space Science ReviewsAbstractObservations and present knowledge of heavy ions with mass ≥ 27 in the magnetosphere are reviewed. There are four ultimate sources of these heavy ions: the solar wind (mainly high charge-state atomic ions), the ionosphere (mainly molecular ions), the atmospheric metal layers that originate ultimately from ablation of meteoroids and possibly ...
