N/Ar Mixed Discharge for Efficient Nitrogen Activation toward Green Ammonia Synthesis Application.

In ammonia synthesis, a new reaction system that does not use hydrogen (H) as a raw material, such as the plasma/liquid (P/L) reaction, contributes to creating a sustainable chemical industry. The P/L reaction is intended to abstract hydrogen atoms from water molecules to synthesize ammonia under ambient conditions without any catalysts but using electrically activated nitrogen species in the plasma. Therefore, the energy transfer process leading to nitrogen activation is key to the P/L reaction.

An effective method for extracting DNA from contaminated soil due to industrial waste.

Recently, labor accidents caused by toxic gas production such as H2S and CH4 have happened at some waste disposal sites and illegal dumping sites in Japan. The gas production has been known to be end products of bacterial respiration. In order to investigate a microbial flora in industrial waste contaminated soil by a DNA-based detection method, we developed a simple DNA extraction method.
