Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

New Potential Haematite and Magnetite Reference Materials for Iron Isotope Measurements by Solution Nebulisation MC‐ICP‐MS and by In Situ ns‐LA‐MC‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Two haematite and magnetite materials were developed as potential Fe isotope reference materials. Solution and in situ LA‐MC‐ICP‐MS analyses yielded consistent δ56Fe values. Both materials are isotopically homogeneous and suitable for in situ Fe isotope calibration.

Electrokinetic analysis reveals common conditioner ingredient interactions with human hair

International Journal of Cosmetic Science, EarlyView.
Novel electrokinetic analysis reveals how cationic surfactant deposition on hair is influenced by chain length and counterion mobility. Longer‐chain surfactants show superior adsorption through enhanced van der Waals interactions, while chloride counterions enable stronger electrostatic interactions.

Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

International Journal of Cosmetic Science, EarlyView.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...
