Hydrogen production by radio frequency plasma stimulation in methane hydrate at atmospheric pressure [PDF]

open access: yes, 2013
Methane hydrate, formed by injecting methane into 100 g of shaved ice at a pressure of 7 MPa\ud and reactor temperature of 0 ??C, was decomposed by applying 27.12 MHz radio frequency\ud plasma in order to produce hydrogen.

Synthesis of Carbon Nanotubes From CO2 Enabled by Fe–Mo Bimetallic Catalysts via Effective CO2 Scavenging

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient
