The Mobility of Major and Trace Elements in EOC Minerals on Parent Chondrite Bodies

open access: yesGeosciences
The combined EPMA and SIMS study of the geochemical features of olivine, low-Ca pyroxene and plagioclase in equilibrated ordinary chondrites (EOCs) has revealed the effect of thermal metamorphism on trace element concentrations in EOC silicate minerals ...

Resolving Asymmetric Spectral Bands

open access: yesEarth and Space Science
This paper introduces the basics of asymmetrical spectral band fitting and discusses the resolution of overlapping Gaussian shapes. We study how to fit overlapping bands with asymmetric Gaussian shapes.

Primary trapped melt inclusions in olivine in the olivine-augite-orthopyroxene ureilite Hughes 009

open access: yes, 2001
We describe the first known occurrence of primary melt inclusions in a ureilite. The ureilite is Hughes 009, one of a small number of ureilites whose primary mineralogy is olivine-augite-orthopyroxene, rather than olivine-pigeonite.

Experimental Evidence of Reaction‐Driven Fracturing and Ultramafic Rock Weakening Induced by CO2 Mineralization

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Carbon sequestration in mafic and ultramafic rocks offers a pathway to mitigate CO2 ${\text{CO}}_{2}$ emissions, while mineralization could precondition rocks for critical mineral extraction. However, the reaction‐driven fracturing processes that increase permeability and weaken rock remain underexplored.

Experimental Reproduction of Olivine rich Type-I Chondrules [PDF]

open access: yes, 2005
Ordinary chondritic meteorites are an abundant type of stony meteorite characterized by the presence of chondrules. Chondrules are small spheres consisting of silicate, metal, and sulfide minerals that experienced melting in the nebula before ...

Supercritical Fluid‐Based Synthesis of Nanomaterials for Energy Storage Applications: A Pathway Toward High‐Entropy Oxides

open access: yesBattery Energy, Volume 5, Issue 6, November 2026.
Supercritical fluid (SCF) synthesis offers tunable solvent properties (T > Tc, P > Pc), enabling rapid nucleation, uniform composition, and controlled growth of nanomaterials. This approach facilitates homogeneous multication mixing and entropy stabilization, promoting single‐phase high‐entropy oxides (HEOs) for advanced electrochemical applications ...

The Dual‐Atom Dispersed Catalysts for High‐Performance Li–S Batteries

open access: yesCarbon Neutralization, Volume 5, Issue 6, November 2026.
With near 100% atomic utilization and tunable coordination environments, dual atom‐dispersed catalysts (DACs) effectively enhance LiPSs adsorption, lower conversion energy barriers, and accelerate sulfur redox reactions. This review covers design principles, catalytic mechanisms, and future directions for DACs in scalable, high‐performance Li–S ...

Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

Seismogenic Consequences of COH‐Fluid Rock Interactions in Ultramafic Fault Zones Insights From Carbonation‐Decarbonation Friction Experiments

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Fluid‐rock interactions have major implications on the frictional behavior of fault rocks. Infiltration of CO2‐bearing fluids in ultramafic fault zones causes the progressive formation of serpentinite, talc‐magnesite (soapstone) and quartz‐magnesite (listvenite) assemblages.
