Dissolved oxygen in pore solution is often a controlling factor determining the rate of the corrosion process of steel bars in concrete. This study reports on the corrosion resistance and polarization properties of steel bars in a mortar specimen mixed with aerobic microorganisms. The addition of the microorganisms in mortar mixtures led to higher corrosion resistance, which was confirmed by the reduced rate of oxygen permeability, based on cathodic polarization properties.

A highly conducting state has been found in a molecular crystal under UV-irradiation. The state reversibly appears in accordance with UV-irradiation, but does not appear by any other method such as raising the temperature, which often induces metallic behavior in insulating molecular crystals. The UV-excited state exhibits conduction and magnetic behavior characteristic of metallic substances. The result suggests that there is an optically accessible, but thermally inaccessible, state of matter.
