Because the composition and construction of a tantalum-MnO2 capacitor is similar to that of a firecracker (a finely divided metal in intimate mixture with a substance that releases oxygen when heated) these capacitors are well-known for failing in pyrotechnic fashion, characterized by explosions and...
Cultures of Nostoc 7120 were bubbled with an CO2/air mixture (1% v/v) and grown photoautotrophically at 30°C in BG11 medium.50 Darkness was implemented on air-CO2-bubbled cultures by covering with aluminum foil plus black velvet. The thermophilic cyanobacterium Thermosynechococcus elongatus BP...

The exact nature of the ground remains to be discovered, but spectroscopy indicates that it is probably a mixture of ices (H2O, CH4, CO2…), hydrocarbon liquid and rocks. Our understanding of Titan has been greatly enhanced by the data returned by the Cassini-Huygens mission still on ...
Should the choice of a certain EDC value be determined by a certain time of reaction in a specific solution (concentration of the redox compound and redox potential)? Should the EDC include a putative fraction of elec- trons donated by mineralization or via irreversible oxidative polymerization (...
