Synthesis of fluorescent silica-coated gibbsite platelets
Journal of Colloid and Interface Science, 2005 We describe the fluorescent labeling of gibbsite particles. Gibbsite particles are first stabilized with polyvinyl pyrrolidone. Subsequently the particles are covered with a silica layer in which a fluorescent dye is incorporated. Both fluorescein and rhodamine dyes have been used. The fluorescent labeling is applicable to gibbsite particles of various

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs
Land Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

Soils and paleosoils of the Galapagos Islands : what we know and what we don't know, a meta-analysis [PDF]
, 2014 Accessible information on Galapagos soils is very limited. Much of the existing, although still scarce, information is several decades old and not easily retrieved. The aim of this paper is to present a critical synthesis.

Carbon‐mixed aluminum hydroxide catalyst for the hydrogen generation of aluminum–water reaction
Journal of the Chinese Chemical Society, Volume 73, Issue 1, Page 105-117, January 2026.Carbon‐modified aluminum hydroxide catalysts, particularly with graphite and activated carbon black, significantly boost hydrogen generation from the Al/water reaction. The synergistic effect of graphite in the Al(OH)3 catalyst results in a remarkable activation energy reduction and achieves complete hydrogen yield in as little as 55 seconds.
