Fuels for Fuel Cells: Requirements and Fuel Processing

CHIMIA, 2004
Polymer electrolyte and solid oxide are the two fuel cell types (PEFC, SOFC) under development in Switzerland. The very distinct operating temperatures of 80°C (PEFC) and 800–950°C (SOFC) impose fundamentally different requirements upon the nature of the fuel; normally purified H2 for the former (CO trace) and usually synthesis gas for the ...

Inhibition of Glutamine Metabolism Attenuates Tumor Progression Through Remodeling of the Macrophage Immune Microenvironment

Advanced Biology, EarlyView.
The prodrug strategy used in this study offers new promise for cancer metabolism‐based therapies. JHU083, a prodrug that, when cleaved by protease in the tumor microenvironment, yields the glutamine antagonist DON. JHU083 inhibits tumor growth by targeting glutamine‐addicted cancer cells and suppressing glutamine‐dependent M2 macrophages, leading to a ...

Surface hydrogen migration significantly promotes electroreduction of acetonitrile to ethylamine

Nature Communications
The electrochemical reduction of acetonitrile (AN) to ethylamine (EA) is an attractive yet challenging process, primarily due to the competing hydrogen evolution reaction (HER).

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.
