Nature at Risk, Finance at Stake: A Systematic Literature Review of Biodiversity Risk in Finance Research

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity‐related financial risk is increasingly recognized not only as a market concern but as an ethical and systemic imperative for businesses and financial institutions. This systematic literature review synthesizes 103 peer‐reviewed studies to examine how biodiversity risk is conceptualized, measured, and integrated within financial ...

White dwarfs with a surface electrical charge distribution: equilibrium and stability

European Physical Journal C: Particles and Fields, 2018
The equilibrium configuration and the radial stability of white dwarfs composed of charged perfect fluid are investigated. These cases are analyzed through the results obtained from the solution of the hydrostatic equilibrium equation. We regard that the

A Multi-Survey Approach to White Dwarf Discovery

, 2012
By selecting astrometric and photometric data from the Sloan Digital Sky Survey (SDSS), the L{\'e}pine & Shara Proper Motion North Catalog (LSPM-North), the Two Micron All Sky Survey (2MASS), and the USNO-B1.0 catalog, we use a succession of methods to ...

Anti‐Inflammatory, Antioxidant, Molecular Docking and Pharmacokinetics Properties of Cycloeucalenone Isolated From Musa × paradisiaca L. Fruit Peels

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study isolated a compound with anti‐inflammatory properties from Musa × paradisiaca fruit peels. The methanol extract was partitioned, and the hexane fraction with the best bioactivity was subjected to column chromatography before characterization via Fourier transform infrared (FTIR), UV–visible (UV–VIS) and NMR analysis.

The Application of Carbon Dots in Crops for Sustainable Agriculture

ChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.
