Subsolar Al/Si and Mg/Si ratios of non-carbonaceous chondrites reveal planetesimal formation during early condensation in the protoplanetary disk
A Morbidelli, G Libourel, H Palme, SA Jacobson… - Earth and Planetary …, 2020 - Elsevier
Abstract The Al/Si and Mg/Si ratios in non-carbonaceous chondrites are lower than the solar
(ie, CI-chondritic) values, in sharp contrast to the non-CI carbonaceous meteorites and the …

Building Earth with pebbles made of chondritic components
Pebble accretion provides new insights into Earth's building blocks and early protoplanetary
disk conditions. Here, we show that mixtures of chondritic components: metal grains …

Balance between Activity and Stability of Single Metal and Intermetallic Compounds for Electrocatalytic Hydrogen Evolution Reaction
HN Li, D Li, TT Hao, YY Sun, NT Suen - Inorganic Chemistry, 2023 - ACS Publications
The higher population of the antibonding state around the Fermi level will result in better
activity yet lower stability of HER (Re vs Ru metal). There seems to be a limitation or balance …

Metal compositions of carbonaceous chondrites
FeNi metals represent an important fraction of chondritic components that remains relatively
unexplored within most carbonaceous chondrite groups. The compositions of these metals …

Chromium stable isotope panorama of chondrites and implications for earth early accretion
We investigated the stable isotope fractionation of chromium (Cr) for a panorama of
chondrites, including EH and EL enstatite chondrites and their chondrules and different …

Silicon isotopic compositions of chondrule silicates in carbonaceous chondrites and the formation of primordial solids in the accretion disk
We determined the silicon isotopic compositions of silicates (olivine and low-Ca pyroxene)
in type I and type II chondrules of the carbonaceous chondrites Allende, Kaba, NWA …

Lewis Cliff 87223, an anomalous enstatite chondrite and the diversity of enstatite chondrites
KR Goss, ML Gray, MK Weisberg… - Meteoritics & Planetary …, 2023 - Wiley Online Library
We studied a thin section of Lewis Cliff (LEW) 87223, an unusual EL3‐related, enstatite
chondrite (EC) that has primary and secondary features not observed in other ECs. We …

Forging inner-disk Al-rich chondrules by interactions of CAI-like melt and ambient gas
The mechanism of gas-melt interactions and the compositions of precursors are key to
understanding the formation of chondrules. To shed light on the two enigmas, we studied the …

Synthesis, Crystal Structure, Electronic Structure, and Electrocatalytic Hydrogen Evolution Reaction of Synthetic Perryite Mineral
Recently, it has been reported that the enstatite chondrite (EC) meteorite may contain
enough hydrogen to provide a plausible explanation for water's initial existence on Earth …
