Tracer Applications of Noble Gas Radionuclides in the Geosciences

, 2013
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Accelerated Discovery of Topological Conductors for Nanoscale Interconnects

Advanced Science, EarlyView.
Copper interconnects exhibit a sharp increase in resistivity at ultra‐scaled dimensions, threatening continued miniaturization of integrated circuits. The gapless surface states of topological semimetals provide conduction channels resistant to localization.

The Geomicrobiology of CO2 geosequestration: a focused review on prokaryotic community responses to field-scale CO2 injection.

Frontiers in Microbiology, 2015
Our primary research paper, titled Changes in the deep subsurface microbial biosphere resulting from a field-scale CO2 geosequestration experiment (Mu et al., 2014), demonstrated selective changes to a deep subsurface prokaryotic community as a result of

Recent changes in the surface salinity of the North Atlantic subpolar gyre [PDF]

, 2002
Sea surface salinity (SSS) was measured since 1896 along 60°N between Greenland and the North Sea and since 1993 between Iceland and Newfoundland. Along 60°N away from the shelves, and north of 53°N, the amplitude of the seasonal cycle is comparable to ...

Geomicrobes: Life in Terrestrial Deep Subsurface

, 2017
The deep subsurface is, in addition to space, one of the last unknown frontiers to human kind. A significant part of life on Earth resides in the deep subsurface, hiding great potential of microbial life of which we know only little. The conditions in the deep terrestrial subsurface are thought to resemble those of early Earth, which makes this ...

Subsurface microbial habitats on Mars [PDF]

We developed scenarios for shallow and deep subsurface cryptic niches for microbial life on Mars. Such habitats could have considerably prolonged the persistence of life on Mars as surface conditions became increasingly inhospitable.

Response of Deep Subsurface Microbial Community to Different Carbon Sources and Electron Acceptors during ∼2 months Incubation in Microcosms

Frontiers in Microbiology, 2017
Acetate plays a key role as electron donor and acceptor and serves as carbon source in oligotrophic deep subsurface environments. It can be produced from inorganic carbon by acetogenic microbes or through breakdown of more complex organic matter. Acetate

Geophysical Explorations for Deep Subsurface Structures

Journal of the Japanese Association for Petroleum Technology, 1968
(1) For seismic reflection method, we have made a study of noise in the area where the noise, what is called ground roll, is quite dominant. As the results, it becomes possible for us to clarify the subsurface structures up to around 4, 000 meters by controling the above noise with use of a well designed T-offset, in-line-offset, etc., because the ...
