Reassessing the organic carbon budget in the Murchison meteorite through an extraction–recovery mass‐balance approach

Meteoritics &Planetary Science, EarlyView.
Abstract A substantial fraction of organic carbon in carbonaceous chondrites has long been described as “missing,” reflecting incomplete recovery and limited resolution of operationally defined organic components. Here, we present a quantitative reassessment of the carbon budget in the Murchison meteorite using an integrated extraction–recovery mass ...

Thin Film Heater for Removable Volatile Protecting Coatings

The Scientific World Journal, 2013
Freshly coated aluminum mirrors have excellent reflectivity at far ultraviolet wavelengths. However, reflectivity rapidly degrades when the mirror surfaces are exposed to atmosphere.

Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Spin–orbit torque-assisted switching in magnetic insulator thin films with perpendicular magnetic anisotropy

Nature Communications, 2016
By virtue of strong spin-orbit coupling, a current-carrying heavy metal may generate a torque on the magnetization of an interfaced ferromagnetic metal.

Massive photinos and ultraviolet astronomy

Physics Letters B, 1982
Abstract The ionisation of hydrogen and helium in the intergalactic medium and of silicon and carbon in galactic halos, including our own, have already tentatively been attributed to photons emitted by decaying neutrinos created in the hot big bang. This hypothesis would require a neutrino mass ∼ 100 eV and a radiative lifetime ∼ 10 27 s.

Far-ultraviolet to Far-infrared Spectral Energy Distribution Modeling of the Star Formation History across M31

The Astronomical Journal
Our neighboring galaxy M31 has been recently surveyed at the far- and near-ultraviolet (FUV and NUV) with the UVIT telescope on AstroSat, which provides unprecedented sensitivity to young stellar populations.

Accelerating Perovskite Solar Cell Development Through High‐Throughput Technologies: Computational Simulation, Automated Experimentation, and Intelligent Integration

Battery Energy, Volume 5, Issue 4, July 2026.
Moving beyond traditional trial‐and‐error, this review explores how integrating high‐throughput computational simulations, automated experimentation, and machine learning significantly accelerates perovskite solar cell development. By establishing intelligent, closed‐loop workflows, these synergistic technologies pave the way for fully autonomous ...

Global Observational Comparison of Large‐Scale Traveling Atmospheric and Ionospheric Disturbances During the May 2024 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of large‐scale traveling atmospheric and ionospheric disturbances (LSTADs/TIDs) via snapshots ...
