Three-dimensional Interaction between a Planet and an Isothermal Gaseous Disk. III. Locally Isothermal Cases

The Astrophysical Journal
We performed linear calculations to determine the Type I planetary migration rate for 3D locally isothermal disks with radial temperature gradients. For 3D disks with radial temperature gradients, the linear wave equation has a divergent term of the ...

Enhanced Reversibility of Li‐Rich Binary Oxide Cathodes through Synergistic Interfacial Regulation for Improved Charge Transfer Kinetics at High Depth of Charge/Discharge

ChemElectroChem, EarlyView.
Synergistic interfacial regulation of Li‐rich binary oxide with 1 wt% Li1.4Al0.4Ti1.6(PO4)3 and 5 wt% polyaniline achieves nearly two orders of magnitude Li+ diffusion enhancement at high depth of charge/discharge, improving initial Coulombic efficiency, rate properties, and suppressing voltage decay by blocking structural degradation pathways. Lithium‐

Tellurium‐Free, Sustainable Thermoelectric Device for Mid‐Temperature Waste Heat Recovery

Carbon Energy, EarlyView.
We demonstrate the novel, low‐cost, non‐toxic, earth‐abundant p‐type and n‐type combination of materials for TEG fabrication. Sustainably fabricated TEG demonstrated a remarkable power of 5 mW and a maximum conversion efficiency of 4.6%. ABSTRACT Famatinite (Cu3SbS4, p‐type) and chalcopyrite (CuFeS2, n‐type) are well‐recognized sustainable minerals ...

Regionalized chemical footprint method to identify aquatic ecotoxicity hotspots of hard disk drive rare‐earth magnets

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 272-283, January 2023., 2023
Abstract The chemical footprint (ChF), which combines life cycle assessment (LCA) and quantitative risk assessment principles, shows promise for exploring localized toxicity impacts of manufacturing processes, which is not achievable with LCA alone. An updated ChF method was applied to the global annual production of a hard disk drive (HDD) rare‐earth ...

Signatures of Atmospheric Mass Loss and Planet Migration in the Time Evolution of Short-period Transiting Exoplanets

The Astronomical Journal
Comparative studies of young and old exoplanet populations offer a glimpse into how planets may form and evolve with time. We present an occurrence rate study of short-period (

Experimental methods in chemical engineering: Electron probe micro‐analysis—EPMA

The Canadian Journal of Chemical Engineering, EarlyView.
ABSTRACT Electron probe microanalysis (EPMA) is a non‐destructive spectroscopic technique to map the chemical composition—quantitative elemental distribution and layer thickness—with a micro‐scale resolution. An electron beam illuminates the surface of a sample and produces backscattered electrons (BSE), secondary electrons (SE), characteristic X‐rays,

Thyroid‐like hormone signaling in invertebrates and its potential role in initial screening of thyroid hormone system disrupting chemicals

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 63-82, January 2023., 2023
Abstract This review examines the presence and evolution of thyroid‐like systems in selected aquatic invertebrates to determine the potential use of these organisms in screens for vertebrate thyroid hormone axis disrupting chemicals (THADCs). Such a screen might support the phasing out of some vertebrate testing.
