An outer membrane c-type cytochrome (OmcZ) in Geobacter sulfurreducens is essential for optimal current production in microbial fuel cells. OmcZ exists in two forms, small and large, designated OmcZ(S) and OmcZ(L), respectively. However, it is still

We created a handmade 3D-printed air sampler to effectively collect live airborne bacteria, and determined which environmental factors influenced the bacteria. Bacterial colony forming units (CFUs) in the air samples (n = 37) were monitored by record

Formation process of AlN from urea and aluminum chloride hexa-hydrate (N/Al = 60) under nitrogen is investigated. An aluminum hexa-urea complex crystallizes on mixing the two raw materials at room temperature. The complexes react with excess urea and

Defects of AlN ceramics with a thermal conductivity from 102 to 216 W m-1 K-1 are investigated using electron spin resonance (ESR). Two ESR signals at g=2.006 and 1.999 are related to thermal conductivity. The g=1.999 signal intensity increases with

The effects of x-irradiation and Ba deficiency in BaTiO3:Ta ceramics were investigated in conjunction with the mechanism of an abrupt increase in electrical resistivity at the Curie temperature Tc, which was called the mode-I positive temperature coe

Aluminum nitride (AlN) powder with no additives was sintered successfully at 1200°C in low-pressure N2 gas using a spark plasma sintering (SPS) process. The density value of the resultant ceramic is as high as 95% of the theoretical one. No openings

Calcium carbonate crystals were grown in a CaCl2–Na2CO3 solution containing an amino acid. We have employed 12 different types of amino acids as additives. The concentrations of noncharged-polar amino acids and those of the acidic ones in CaCO3 pre

Radiation-induced organic radicals in CaCO3 doped with γ-aminobutyric acid and glycine, and Li2CO3 with adsorbed glycine were investigated by electron spin resonance. Isopropyl radicals occurred in CaCO3 doped with γ-aminobutyric acid. A signal at

Radiation-induced radicals in sulfite-doped calcite and aragonite were characterized by ESR. Among the many ESR signals produced, only four signals are dependent on the SO2-3 concentration; an axial signal (g⊥=2.0038 and g|=2.0024) in calcite, and
