Ecogenomics and limnological dynamics of a new Thiocapsa species blooming in the whole water column of a karstic lake

open access: yesLimnology and Oceanography, EarlyView.
Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Revisiting Fused‐Pyrrolo‐1,10‐Phenanthroline Derivatives: Novel Transformations and Stability Studies

open access: yesChemistryOpen, EarlyView.
The synthesis of new pyrrolo[3',4':3,4]pyrrolo[1,2‐a][1,10]phenanthroline derivatives is performed starting from [3+2] cycloaddition of in situ generated ylides, followed by cycloadducts oxidation and other transformations. The structures of the unexpected intermediates and final compounds are obtained from nuclear magnetic resonance and single‐crystal

SAND, PLANTATION URBANISM AND THE EXTENDED POLITICAL ECOLOGY OF INFRASTRUCTURES IN INDIA

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Recently, large parts of India and the global South have witnessed widespread sand extraction from rural sites for urban infrastructure projects, causing extensive environmental damage. Critical scholarship has theorized these sites as new extractive frontiers that facilitate the needs of green energy transitions and planetary urbanization. In
