Location of a new ice core site at Talos Dome (East Antarctica)

Annals of Geophysics, 2006
In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East Antarctic plateau, represents the new selected site for a new deep ice core drilling. The increasing interest in this region is due to the fact

Ice-flow modeling results to assist the interpretation of millennial-scale ice cores recovered at the high-Alpine ice drilling site Colle Gnifetti, Swiss/Italian Alps

, 2019
Ice-flow modeling studies were conducted to assist the interpretation of millennial-scale ice cores recovered at the high-Alpine drilling site Colle Gnifetti, Swiss/Italian Alps. Backwards trajectories starting from the borehole sites at different depths

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Lessons learned from shallow subglacial bedrock drilling campaigns in Antarctica

Annals of Glaciology
We review successes and challenges from five recent subglacial bedrock drilling campaigns intended to find evidence for Antarctic Ice Sheet retreat during warm periods in the geologic past.

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

Advanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Data-driven optimization of Antarctic shallow ice core site selection

Journal of Glaciology
Antarctic ice cores provide highly detailed climate histories; yet, the existing proxy record is limited by uneven spatial and temporal coverage. Collecting new ice cores will improve our understanding of climate processes in Antarctica, but the cost of ...

Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...
