Guide to the nature and methods of analysis of the clay fraction of tephras from the South Auckland region, New Zealand. [PDF]
, 1983 The manual outlines some of the more common laboratory procedures available for qualitatively and quantitatively analysing the composition of the tephric clays, many of which are difficult to determine because of their short range order or 'amorphous ...

Rheological behaviour and spectroscopic investigations of cerium-modified AlO(OH)colloidal suspensions [PDF]
, 2011 The rheological behaviour of aqueous suspensions of boehmite (AlO(OH)) modified with different Ce-salts (Ce(NO3)3, CeCl3, Ce(CH3COO)3 and Ce2(SO4)3) was investigated at a fixed Ce/Al molar ratio (0.05).

Advanced Energy Materials, Volume 16, Issue 10, 11 March 2026.The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...

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

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.

Hydrological Processes, Volume 40, Issue 3, March 2026.Riverine solute fluxes peak during the wet season, emphasising the role of tropical rainfall in driving nutrient delivery to the ocean. Seasonal peaks in nutrient fluxes highlight the need for longer‐term monitoring to detect potential interannual trends.

Acid Leaching Performance of Gibbsite-type Bauxite with High Iron Content
Kuangchan zonghe liyong, 2022 High-iron bauxite with low A/S ratio cannot be extracted economically by Bayer process. Taking a low-grade gibbsite ore abroad as the research object, the acid leaching performance of gibbsite was studied by using hydrochloric acid as leaching medium ...

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters
