Ligand Redox Noninnocence in Bis(phosphinimine) Diarylamido Pincer Complexes of Nickel

European Journal of Inorganic Chemistry, EarlyView.
The oxidative noninnocence of a bis(phosphinimine) ligand featuring a diarylamido backbone was investigated for several nickel complexes. Radical/charge delocalization across the aromatic backbone plays an important role in the stabilization of the diarylaminyl and putative diarylnitrenium complexes.

Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

European Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.

Hydrogen Sulfide Application Reduces Postharvest Weight Loss in Tomato Fruit by Promoting Cuticular Wax Accumulation

Future Postharvest and Food, EarlyView.
NaHS‐derived H2S enhances postharvest tomato fruit storability by reducing weight loss, delaying peel wrinkling, and maintaining peel firmness. This response is associated with increased cuticular wax deposition and upregulation of wax biosynthetic and regulatory genes, without marked changes in PME or PG activities. ABSTRACT During postharvest storage,

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

Geological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

Geological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.
