Emission of reactive oxygen species during degradation of iron gall ink [PDF]

, 2010
Iron gall inks are characterised by high contents of acids and transition metals, promoting degradation of cellulose due to hydrolysis and oxidation, respectively. Their chemical interaction with the environment is not well understood, especially in view

Electrochemically Driven Tandem In‐Plane Reduction and FeCl3‐ Intercalation of Highly Crystalline Graphene Oxide Thin Films

Advanced Functional Materials, EarlyView.
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–

Isolation and identification of cholesteryl alkyl ethers from bovine cardiac muscle

Journal of Lipid Research, 1968
Cholesteryl alkyl ethers have been isolated from bovine cardiac muscle and characterized by thin-layer and gas-liquid chromatography. The fraction contained at least three homologues. Cholesteryl hexadecyl ether, which accounted for over 90% of the total

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.
