Electron Paramagnetic Resonance-detectable Electron Acceptors in Beef Heart Mitochondria

The EPR-detectable (24.2 K) electron acceptors of the DPNH-ubiquinone reductase segment of the electron transfer system of beef heart mitochondria were studied in preparations of varying complexity. Four distinct iron-sulfur centers associated with this segment of the electron transfer system were identified. They occur in approximately equal concentrations, and this concentration approximates ...

Butterfly effects

Concerns about the potential toxicity of pollen from genetically modified maize on neighbouring butterflies prompted urgent studies, reports Nigel Williams.

Ion Effects in the Slc Electron Damping Ring

We report on the ion-related beam behavior in the electron damping ring during unusually poor vacuum conditions in the weeks that followed a catastrophic kicker chamber failure that contaminated the ring vacuum system. The vacuum gradually improved over several months of beam operation, during which time the vertical emittance remained blown up by a factor of 2. The emittance blowup was accompa...

An Overview of Electron Acceptors in Microbial Fuel Cells

Microbial fuel cells (MFC) have recently received increasing attention due to their promising potential in sustainable wastewater treatment and contaminant removal. In general, contaminants can be removed either as an electron donor via microbial catalyzed oxidization at the anode or removed at the cathode as electron acceptors through reduction. Some contaminants can also function as electron ...
