The H-2/CH4 ratio during serpentinization cannot reliably identify biological signatures

, 2016
Serpentinization potentially contributes to the origin and evolution of life during early history of the Earth. Serpentinization produces molecular hydrogen (H-2) that can be utilized by microorganisms to gain metabolic energy.

Native H2 Exploration in the Western Pyrenean Foothills

Geochemistry, Geophysics, Geosystems, 2021
Native hydrogen (H2) may represent a new carbon free‐energy resource, but to date there is no specific exploration guide to target H2‐fertile geological settings. Here, we present the first soil gas survey specifically designed to explore H2 migration in

Characterization of Geochemistry in Hydrothermal Sediments From the Newly Discovered Onnuri Vent Field in the Middle Region of the Central Indian Ridge

Frontiers in Marine Science, 2022
The recently discovered Onnuri hydrothermal vent field (OVF) is a typical off-axis ultramafic-hosted vent system, located on the summit of the dome-like ocean core complex (OCC) at a distance of ∼12 km from the ridge axis along the middle region of the ...

Magnetic Characteristics of Highly Serpentinized Peridotite in the Iberia Abyssal Plain and Implications for Marine Magnetic Anomalies

Geochemistry, Geophysics, Geosystems
Serpentinization, a consequence of water‐rock interaction in mafic and ultramafic rocks, refers to the hydrothermal alteration of olivine and pyroxene with serpentine as the typical product.

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Shallow marine serpentinization-derived fluid seepage in the Upper Cretaceous Qahlah Formation, United Arab Emirates [PDF]

, 2021
Serpentinization of ultramafic rocks in the sea and on land leads to the generation of alkaline fluids rich in molecular hydrogen (H2) and methane (CH4) that favour the formation of carbonate mineralization, such as veins in the sub-seafloor, seafloor ...

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

Advanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).
