Surface Symphony: Orchestrating DPPC/DOPC Monolayer Behavior

open access: yesMicroscopy Research and Technique, EarlyView.
Langmuir trough and atomic force microscopy reveals the physical nature of DPPC and DOPC mixed monolayers. ABSTRACT This study investigates the impact of environmental factors and lipid composition on the structural and morphological properties of DPPC/DOPC (1,2‐Dipalmitoyl‐sn‐glycero‐3‐phosphocholine/1,2‐dioleoyl‐sn‐glycero‐3‐phosphocholine ...

Influence of mica on unconfined compressive strength of a cement-treated weathered granite gravel

open access: yesJournal of the South African Institution of Civil Engineers, 2012
The road construction industry faces a shortage of naturally occurring gravel materials that meet the requirements for base or even at times sub-base quality. This situation is exacerbated in some cases by the occurrence of mica in soils.

Determining Exchangeable Base Cations in Forest Soils: A Comparison of Three Methods

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Accurately determining exchangeable base cations is critical for assessing base cation depletion in acid forest soils, where various extraction methods may yield different results. Aim The aim was to quantify differences in the effectiveness of BaCl2, NH4OAc (pH 7), and Cohex methods in extracting base cations from acid forest soils

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...

Interstratified Illite‐Hydroxy‐Interlayered Smectite—A Disorder Structure Model for Quantification Using Rietveld Refinement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The acidic weathering of soils is known as a problem for decades. It leads to the deterioration of essential soil properties, including soil fertility, water, or cation buffering capacity due to solution and solid storage of Al3+ by polymerization in the interlayer of (former) swellable clay minerals.

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

open access: yesJournal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).
