Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Ionization balance of Ti in the photospheres of the Sun and four late-type stars

, 2011
In this paper we investigate statistical equilibrium of Ti in the atmospheres of late-type stars. The Ti I/Ti II level populations are computed with available experimental atomic data, except for photoionization and collision induced transition rates ...

Tuning Active Hydrogen on Reconstructed RuO2/Co(OH)2 Catalysts for Selective Ammonia Synthesis

Advanced Materials, EarlyView.
A combined approach of precatalyst design and electrolyte engineering is employed to develop highly active, selective, and stable catalysts for electrochemical nitrate reduction. In alkaline media, the reconstructed RuO2/Co(OH)2 catalyst demonstrates impressive performance in ammonia synthesis, rechargeable Zn‐NO3− battery, and the remediation of ...

Bioturbation as a key driver behind the dominance of Bacteria over Archaea in near-surface sediment

Scientific Reports, 2017
The factors controlling the relative abundances of Archaea and Bacteria in marine sediments are poorly understood. We determined depth distributions of archaeal and bacterial 16S rRNA genes by quantitative PCR at eight stations in Aarhus Bay, Denmark ...

Recent Advances in Ene Reactions with Carbon Enophiles

Advanced Synthesis &Catalysis, EarlyView.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

Equilibrium Abundances of Stable Isotopes [PDF]

Progress of Theoretical Physics, 1961
Equilibrium distribution calculated using the analogue of Saha's ionization formula is examined with the recent nuclear masses and abundance data. It is found that up to A = 92, the abundance distribution can be well reproduced. The electron degeneracy which becomes important is also considered for the region A = 64-92.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

Advanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Reprogramming of Fatty Acid Metabolism via PPARα‐Orchestrated FADS2 in Keratinocytes Modulates Skin Inflammation in Psoriasis

Advanced Science, EarlyView.
This study identifies fatty acid desaturase 2 (FADS2) as a key regulator linking polyunsaturated fatty acid (PUFA) metabolism to psoriatic inflammation. FADS2 deficiency impairs docosahexaenoic acid (DHA) biosynthesis, enhances NF‐κB signaling, and promotes neutrophil‐driven skin inflammation. PPARα transcriptionally activates FADS2, and its activation
