Photoconductive AFM () can measure both photogenerated free charges, as well as enhanced photoconductivities, which have also been reported with SSPM and EFM. When the work function of the tip is well matched with the density-of-states for the induced carrier of interest, current will flow through the tip to give a local measurement of charge Cited by: 4. Methoxypyrazines are a class of chemical compounds that produce odors. The odors tend to be undesirable, as in the case of certain wines, or as defensive chemicals used by insects such as Harmonia axyridis which produces isopropyl methoxy pyrazine (IPMP). They have also been identified as additives in cigarette ion thresholds are very low, typically .

The characteristics of α e = f(E d) for the real Si() surfaces after changing their electrical conductivity by means of optical excitations are presented in Figure 6.

Abstract. Methanophenazine is a naturally occurring phenazine of nonbacterial origin, which has recently been isolated from the cytoplasmic membrane of Methanosarcina mazei Gö1 archaea.

It is not only the first and so far the sole phenazine derivative from archaea, but also the first one that is acting as an electron carrier in a respiratory chain – a biologic function.
