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 ...

Serpentine tongue [PDF]

Neurology, 2008
A 69-year-old man presented with parkinsonism (asymmetric pill-rolling tremor, bradykinesia, and rigidity) and a distinctive serpentine tongue dyskinesia (video). The movement was constantly present at rest, stopping …

Hybrid Metal–Carbon Ink for Printed Stretchable Temperature Sensors

Advanced Engineering Materials, EarlyView.
We prepare conductive inks for temperature sensing with silver flakes and carbon or graphite flakes in a silicone elastomer matrix. Silver dominates the temperature‐dependent conductivity, while the carbon filler network ensures the stability of the conductive pathways and retains function under strain.

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Metabolic challenges and key players in serpentinite-hosted microbial ecosystems

Frontiers in Microbiology, 2023
Serpentinite-hosted systems are amongst the most challenging environments for life on Earth. Serpentinization, a geochemical alteration of exposed ultramafic rock, produces hydrothermal fluids enriched in abiotically derived hydrogen (H2), methane (CH4),

Elasticity of serpentines and extensive serpentinization in subduction zones [PDF]

Geophysical Research Letters, 2007
Elastic constants of lizardite [Mg3Si2O5(OH)4] were computed using first‐principles quantum mechanical calculations within the density functional theory. The predicted c‐axis compressibility is much larger than measured. Modeling of the weak O‐H⋯O interactions between layers must be improved in order to better predict layered hydrated mineral elastic ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.
