Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
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 ...

Reuse of Zeolite By-Products Derived from Petroleum Refining for Sustainable Roads

Advances in Materials Science and Engineering, 2019
The reduction in consumption of natural resources (fuel, gas, etc.) and contaminant emissions (CO2, CO, NOx, etc.) during the production of asphalt mixtures has become one of the main challenges in road engineering.

Determination of refined petroleum product import fees

, 1976
To quantify the import fee required to discourage product imports into the US East Coast market, it was necessary to determine the locations of the most competitive offshore refineries. The effect of the present entitlements program was not included and the foreign crude to US refiners was included at projected world market prices.

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries

Advanced Functional Materials, EarlyView.
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,
