Changes in the emission intensities of ultraweak biophoton emission during the cell proliferation of human carcinoma cell culture (TE9 cell line) were detected using a highly sensitive and low noise measurement apparatus coupled with a flow culture system. In the sampling period of 93 h, the biophoton emission intensity from the culture followed a similar(More)
We describe the spatial distribution and temporal correlation analysis of ultraweak biophoton emission based on photoelectron pulse time series and position measurement techniques. Experimental results on the spatio-temporal variation of biophoton emission from soybean seedlings after physical and chemical stimulation to the root tip are analyzed. Our(More)
An organic p-n bilayer photocatalysis system successfully induced the oxidative decomposition of hydrazine (N2H4) into N2 and simultaneously yielded H2 from H(+). This demonstrates the first instance of the stoichiometric decomposition of N2H4 under visible-light irradiation.
The photoelectrode characteristics of an organic p/n bilayer in the water phase were studied with respect to film; 3,4,9,10-perylenetetracarboxylic-bisbenzimidazole (PTCBI, an n-type semiconductor) was used in combination with 29H,31H-phthalocyanine (H₂Pc, a p-type semiconductor). When H₂Pc was vapor-deposited on top of the PTCBI layer on a heated substrate(More)
