Assessing the Effect of Mineralogy and Reaction Pathways on Geological Hydrogen (H2) Generation in Ultramafic and Mafic (Basaltic) Rocks

open access: yesHydrogen
This study evaluates the impact of mineralogy, elemental composition, and reaction pathways on hydrogen (H2) generation in seven ultramafic and mafic (basaltic) rocks. Experiments were conducted under typical low-temperature hydrothermal conditions (150 °

The Potential for Abiotic Methane in Arctic Gas Hydrates [PDF]

open access: yes, 2016
Most methane enclosed in gas hydrates is biotic in origin, formed by microbial degradation of sedimentary organic matter. Increasingly, there is evidence that substantial gas hydrate may also be sourced from thermogenic decomposition of organic matter ...

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

A Plug‐and‐Play Volume Minimizing Micromixer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Microscale fluid mixing has numerous applications where rapid and efficient mixing is required, including drug discovery, bio‐analysis and point‐of‐care diagnostics. Conventional soft lithography processes, however, make the integration of robust and reliable mixing difficult to implement in practice, especially across different flow rates ...

The break-up of continents and the formation of new ocean basins

open access: yes, 2002
Rifted continental margins are the product of stretching, thinning and ultimate break-up of a continental plate into smaller fragments, and the rocks lying beneath them store a record of this rifting process.

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

open access: yesAdvanced Science, EarlyView.
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...

Abiotic Methane in Continental Serpentinization Sites: An Overview ☆

open access: yes, 2017
Until 2008 methane in land-based serpentinized peridotites (MSP) was considered to be an unusual and rare occurrence of abiotic gas. Today, reports of MSP are increasing for numerous localities worldwide in low temperature settings in ophiolites ...
