Lateglacial and Holocene mountain glacier fluctuations near Cape Farewell South Greenland inferred from 10Be moraine dating

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT We report 43 new 10Be exposure ages and six 26Al/10Be measurements from replicates from a small piedmont mountain glacier located at Cape Farewell (south Greenland) and temperature anomalies estimated from equilibrium‐line altitude (ELA) changes derived from 3D glacier reconstruction carried out using the ‘GlaRe’ toolbox.

Mid‐Holocene drying of K'gari lakes (subtropical eastern Australia) necessitates re‐evaluation of the El Niño–Southern Oscillation climate links and future drying risk

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Holocene history of Australia's climate is surprisingly poorly understood. This is, in part, because of the relatively weak forcing of Holocene climate versus that of the late Pleistocene. However, it is commonly suggested that eastern Australia dried during the mid‐ to late‐Holocene and that this was in response to increased activity in ...

The Pace di Siena and its Gems

open access: yesJournal of Raman Spectroscopy, EarlyView.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.

Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions

open access: yesJournal of Raman Spectroscopy, EarlyView.
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).

Patients with preoperative bone marrow oedema benefit more substantially from medial meniscus posterior root repair

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To analyze the clinical outcomes of the surgical repair of medial meniscus posterior root tear (MMRT) in patients with preoperative bone marrow oedema (BME). Methods Patients who underwent arthroscopic pull‐out repair for MMRT between 2010 and 2022 were retrospectively reviewed, and those with a minimum of two years of follow‐up were ...
