Using OSL to assess hypotheses related to the impacts of land use change with the early nineteenth century arrival of Europeans in south-eastern Australia: an exploratory case study from Grabben Gullen Creek, New South Wales [PDF]

open access: yes, 2014
A common explanation for intense soil erosion and gullying in SE Australia is the introduction by Europeans of new land use practices following their arrival in Australia in the late 18th century.

Thermoluminescence and optically stimulated luminescence of gamma-irradiated mineral zircon [PDF]

open access: yes, 2007
Thermoluminescence (TL) manifested by gamma-irradiated mineral zircon has shown a strong TL peak at about 165 °C which is due to recombination of electrons and Dy3+ related shallow hole traps.

Application of OSL strips in CT dosimetry according to the AAPM methodology

open access: yesBrazilian Journal of Radiation Sciences, 2023
Computed tomography (CT) images contribute to high-quality medical diagnosis, but radiation dose can be quite high, requiring accurate assessment. CT dose index (CTDI) was developed for dosimetric purposes, but for scanners operated exclusively in axial ...

The chronostratigraphy of Late Pleistocene glacial and periglacial aeolian activity in the Tuktoyaktuk Coastlands, NWT, Canada [PDF]

open access: yes, 2006
Aeolian periglacial sand deposits are common in the Tuktoyaktuk Coastlands of Western Arctic Canada. Regionally extensive and thick aeolian sand-sheet deposits have been observed in two major stratigraphic settings: within a sand unit characterized by ...

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.

Radiocarbon and Luminescence Dating of Lacustrine Sediments in Zhari Namco, Southern Tibetan Plateau

open access: yesFrontiers in Earth Science, 2021
There are more than 1,000 lakes within the Tibetan Plateau (TP), all of which are sensitive to changes in regional climate and local hydrology. Lacustrine sediments within these lakes preserve a good record of these changes.

Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Reasoning behind discrepancies in periodontal diagnosis and classification: A mixed‐methods analysis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background While discrepancies in periodontal diagnosis and classification among dental providers with various educational backgrounds have been reported when the 2017 Classification of Periodontal Conditions was applied, the cognitive reasoning processes underlying these discrepancies remain underexplored.
