Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates
Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

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 ...

Structure and thermodynamics of platelet dispersions
, 2008 Various properties of fluids consisting of platelike particles differ from the corresponding ones of fluids consisting of spherical particles because interactions between platelets depend on their mutual orientations. One of the main issues in this topic

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

The master molecule that built biology: How water shaped the chemistry of life
Protein Science, Volume 35, Issue 5, May 2026.Abstract The deep entanglement of biomolecular structure and function with aqueous systems supports the view that water actively sculpted both molecules and processes during the origins of life and continues to constrain evolution today. Nature's rules of biochemistry and biophysics have survived for nearly 4 billion years.

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 ...

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...

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).
