Platinum is highly desired in jewelry and as a catalyst, but in both cases it is expensive. Now, researchers have found a way to replace the platinum catalyst in their hydrogen generating microbial ...

A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid ...

A new catalyst material could dramatically reduce the cost of producing microbial fuel cells. Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same ...

The broad application of microbial electrolysis cells (MECs) requires a system characterized by low cost and high operational sustainability. Biocathode MECs, which only require bacteria as the ...

Biofilm-forming marine bacterial isolates Paenibacillus lautus NE3B01, Pseudomonas mendocina NR802, Stenotrophomonas acidaminiphila NCW702 and Pseudomonas pseudoalcaligenes NP103 in microbial fuel ...

A microbial electrolysis cell (MEC) shown with the power source used to augment the voltage produced by the bacteria. Bacteria grow in the anode chamber, forming a biofilm on graphite granules, while ...

A new reactor powered in part by microbes can generate hydrogen gas while producing solutions of hydrochloric acid and sodium hydroxide for use in carbon dioxide sequestration (Environ. Sci. Technol.

When nature designed lignin — the fibrous, woody material that gives plants their rigid structure — it didn’t cut any corners. Incredibly slow to break down, lignin is so sturdy and long lasting that ...
