Ablation of Martian glaciers [PDF]
Glacier like landforms are observed in the fretted terrain of Mars in the latitude belts near + or - 42 deg. It was suggested that sublimation or accumulation-ablation rates could be estimated for these glaciers if their shapes were known.

Does Climate Risk Affect Employment Decisions? International Evidence
ABSTRACT This study investigates the effect of climate risk on corporate employment decisions. Using a large sample from 41 countries, we find a positive association between climate risk and underinvestment in labor, notably manifesting as excessive employee layoffs.

ABSTRACT The orbicularis oculi muscle (OOc) is strongly associated with facial aging as its contraction causes the formation of crow's feet. Botulinum neurotoxin (BoNT) injection is a representative treatment targeting muscle. The aim of this study was to demonstrate the anatomical relationship between the OOc and the zygomaticus complex muscles, and ...

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.
