Enhancing biodegradation of polycyclic aromatic hydrocarbons using bacterial consortia and biofilm

Abstract The release of petroleum and its constituents, such as polycyclic aromatic hydrocarbons (PAHs), into the environment poses a significant global threat due to their toxic, genotoxic, mutagenic, and/or carcinogenic properties. Using indigenous PAH-degrading bacteria to dec...

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

ABSTRACT Sulfur‐free polymeric materials simultaneously achieving ultrahigh refractive index ( n > 1.8), low optical dispersion, high visible transparency, and thermal robustness have remained elusive due to the fundamental polarizability–dispersion trade‐off. Here, we introdu...
