Compatibility Between HPEG Type PCEs With Various Anionic Charge Densities and Portland Cements With Different C3A Contents

open access: yesJournal of Applied Polymer Science, EarlyView.
Evaluation of the compatibility between PCEs possessing varying anionic charge densities and Portland cements with different C3A contents. ABSTRACT This study focused on the compatibility of phosphate and sulfonate‐substituted polycarboxylate ether‐based water‐reducing admixtures (PCE) exhibiting different anionic charge densities with Portland cements

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons

open access: yesAdvanced Physics Research, EarlyView.
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

Culturally Imbued Trees: Physical and Metaphysical Connections

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Australian Aboriginal song‐lines and Dreaming tracks follow the movement and interactions of ancestral beings and are marked by physical features associated with those ancestral beings at culturally significant places, often termed ‘sacred sites’.

Multi‐Century Grindstone Quarrying at Brumby Yard, Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT The timing and duration of prehistoric quarrying is poorly understood within Australia, with limited ages available for quarries owing to the difficulties in dating these rock‐sediment constructions. We report the first multi‐sample, optically stimulated luminescence ages from quarry pits in Brumby Yard, an Aboriginal grindstone quarry ...
