The chronology and tectonic style of landscape evolution along the elevated Atlantic continental margin of South Africa resolved by joint apatite fission track and (U-Th-Sm)/He thermochronology [PDF]

Atlantic-type continental margins have long been considered “passive” tectonic settings throughout the entire postrift phase. Recent studies question the long-term stability of these margins and have shown that postrift uplift and reactivation of ...

Thermal history modeling of the H chondrite parent body [PDF]

, 2012
The cooling histories of individual meteorites can be empirically reconstructed by using ages from different radioisotopic chronometers with distinct closure temperatures.

SAXS study on the morphology of etched and un-etched ion tracks in apatite

EPJ Web of Conferences, 2015
Natural apatite samples were irradiated with 185 MeV Au and 2.3 GeV Bi ions to simulate fission tracks. The resulting track morphology was investigated using synchrotron small angle x-ray scattering (SAXS) measurements before and after chemical etching ...

Gas migration for terrestrial gas hydrates in the Juhugeng mining area of Muli basin, Qilian Mountains, Northwest China

Energy Exploration & Exploitation, 2020
The Juhugeng mining area in the Qilian Mountains is the only district of China where terrestrial gas hydrate has been found. This paper aimed at studying the gas migration for gas hydrates based on fluid inclusion and apatite fission track experiments ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Detrital Zircon Fission-Track Thermochronology of the Present-Day Isère River Drainage System in the Western Alps: No Evidence for Increasing Erosion Rates at 5 Ma

Geosciences, 2013
The Isère River system drains parts of the Western Alps in south-eastern France. Zircon fission-track data of the Isère River and its tributaries show a range of apparent cooling ages from about 7 to 150 Ma.

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges

Oikos, EarlyView.
Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

Boron‐10 carriers and their applications in boron neutron capture therapy

Precision Radiation Oncology, EarlyView.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.
