Visible‐Light Photoredox Catalysis in the Intramolecular Dicarbonylation of Alkenes: Catalyst‐Dependent Divergent Syntheses of Both 1,4‐Dicarbonyls and α‐Hydroxy‐β,γ‐Unsaturated Lactams From 1,2‐Dicarbonyls

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Catalyst‐dependent divergent syntheses were developed. Intramolecular dicarbonylation of vinyl halides under metal‐free either thermal or visible light photocatalytic conditions were explored to produce a series of 1,4‐dicarbonyls with two different carbonyl moieties and a lactam ring.

Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4419-4434, August 2026.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

The Role of Telemedicine in Enhancing Surgical Care Delivery in Africa: A Literature Review

Health Science Reports
Background and Aims In Africa, telemedicine holds great potential to revolutionize surgical care delivery, especially in areas where access to quality treatment is scarce. Data about the use of these services in African countries is, however, limited. To

Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Unraveling Spatiotemporal Heterogeneity and Driving Mechanism of Vegetation Recovery in Co‐Seismic Landslide Areas via Nonlinear Trajectories and Bayesian Networks

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We developed an integrated GAM–Bayesian framework to diagnose the nonlinear recovery dynamics of vegetation in landslide‐affected areas. Our model reveals that most sites reached a key recovery inflection point within 5–7 years, with faster recovery occurring under warm, moist, and moderate light conditions.

Livestock Depredations and Prevention Strategies to Foster Human‐Carnivore Coexistence in Western Mongolia's High Mountain Systems

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The implementation of visual deterrents (i.e., Foxlights) proved to be effective in reducing the number of night‐time livestock depredations by both snow leopards and wolves. ABSTRACT The decline of large carnivores and the overabundance of livestock practices contribute significantly to ecosystem degradation.

Neuro-ophthalmology and migraine: visual aura and its neural basis

International Journal of Emergency Medicine
Background Migraine, a chronic neurological condition often accompanied by visual aura, which affects 15–33% of migraineurs, often presents as transient visual disturbances such as scintillating scotoma and teichopsia. These symptoms arise primarily from

The contribution of small trees to carbon stocks along a recovery gradient in the Amazonia

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Most ecological knowledge about carbon recovery during natural regeneration in tropical regions has focused on individuals exceeding 10 cm in diameter. However, the contribution of smaller individuals to aboveground carbon (AGC) across successional gradients remains poorly quantified, despite their potentially substantial role during early ...
