First disk-resolved spectroscopy of (4) Vesta
, 2009 Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that is has been resurfaced by basaltic lava flows, not too different from the

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis
Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

High Pressure Formation of the Eight‐Fold Coordinated Post‐Post Spinel MgFe2O4
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract MgFe2O4 was probed to 74(1) GPa and 2,840(130) K as a low‐pressure analog to post‐post spinel Mg2SiO4 predicted in super‐Earths using synchrotron multigrain X‐ray diffraction techniques in the laser‐heated diamond anvil cell. With high‐temperatures above 65 GPa the eight‐fold coordinated δ‐MgFe2O4 (Th3P4‐type) is stable with Mg and Fe ...
