Advances in fuel cell applications reflect the ability of reformers to produce hydrogen. This work presents a flexible micro temperature sensor that is fabricated based on micro-electro-mechanical systems (MEMS) technology and integrated into a flat micro methanol reformer to observe the conditions inside that reformer. The micro temperature sensor has higher accuracy and sensitivity than a con...
Rodents and non-rodent species metabolize methanol to formaldehyde to formic acid to carbon dioxide. There are two major differences, however. Rodents (mice and rats) metabolize methanol to formaldehyde using the enzyme catalase, whereas humans use alcohol dehydrogenase (ADH1). A byproduct of rodent methanol metabolism is hydrogen peroxide, a reactive oxygen species (ROS). ROS may be involved i...
Formic acid is the main breakdown product of mild hydrothermal treatment of carbohydrates. Further conversion to methanol was achieved using Cu as catalyst and Zn as reductant under hydrothermal conditions of 250-325 °C for 3-12 h. Both Cu and Zn used were commercial Cu and Zn powders with particle sizes of 200 mesh. A methanol yield of 32% was achieved at 300 °C for 5h with 6.5 mmol of Cu, 12 ...
