By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

This study presents a green processing route for high‐performance reduced graphene oxide (rGO) transparent conductive films (TCFs) using highly crystalline Brodie's GO. In‐plane electrochemical reduction forms rGO on insulating substrates without toxic reductants or heat. Subsequent FeCl₃ intercalation enhances conductivity, overcoming the transparency–

Growth of upper tropospheric aerosols due to uptake of HNO3 [PDF]
The effect of nitric acid on the equilibrium size distributions of upper tropospheric aerosols is calculated as a function of relative humidity. It is shown that HNO3 concentrations above a few tenths of a ppb can cause substantial increases in haze mode
