  • Patent number: 11600817
    Abstract: Provided is a novel production method for producing silicon clathrate II. In the production method for producing silicon clathrate II, in a reaction system in which a Na—Si alloy containing Na and Si and an Na getter agent coexist so as not to be in contact with each other, the Na—Si alloy is heated and Na evaporated from the Na—Si alloy is thus caused to react with the Na getter agent to reduce an amount of Na in the Na—Si alloy.

  • Patent number: 11563227
    Abstract: Benthic microbial biofuel cells (BMFCs) are a potential non-toxic and renewable source of underwater power. BMFCs function by coupling an anaerobic anode to an oxygenated cathode. However, current in-situ BMFCs on average produce less than 1W of power. Potential causes are internal ohmic resistance and low capture efficiency of the bacteria-generated charge due to macroscopic average distances between bacteria and electrodes. A microfluidic BMFC chip is enclosed to study those potential causes. The chip is built using elastomer microfluidics to provide biologically-inert microfluidic confinement of the bacteria, forcing them to be no further away than the height of the containment microchamber (?90 ?m) from the microelectrode matrix built on the glass substrate of the chip. The matrix captures the charge without location bias (due to its H-architecture) and conducts it to the outside circuit.
