TL;DR: A review of the state of the art and scientific needs for heterogeneous electrocatalysts for electrochemical reduction of dinitrogen to ammonia can be found in this article, with a particular focus on how mechanistic understanding informs catalyst design.

TL;DR: It was found that the soluble COD (SCOD) removal efficiencies remained over 90% throughout the operational period, mainly because of methanogenic activity, which accounted for 35 to 58% of the SCOD removed at a loading rate of 1.0 g COD/L/ day.

TL;DR: Recent advances in biofuel cell technology have addressed deficiencies and include methods to increase lifetime and environmental stability, but remain limited by short lifetimes, low power densities and inefficient oxidation of fuels.

TL;DR: An upflow microbial fuel cell system with a U-shaped cathode inside the anode chamber was developed and produced a maximum volumetric power of 29.2 W/m3 and maintained soluble chemical oxygen demand (COD) removal efficiencies exceeding 90% and volatile fatty acid concentrations of approximately 40 mg/L, indicating efficient wastewater treatment.

TL;DR: The incorporation of substrate channelling into synthetic cascades is a rapidly developing concept, and recent examples of the fabrication of cascades with controlled diffusion and flux of intermediates are presented.
