In this work, condensation characteristics of water droplet on metallized nanofibers mat on short time scale has been studied. It has been shown that condensation of water droplet on copper nanofibers mat is delayed to a great extent in comparison to condensation on bare copper. It has been observed that on copper nanofibers mat the number of water droplets is much less than on bare copper and did not cause film as on bare coppers. At the end theoretical analysis showed that such behavior can be explained by Kelvin effect.

An alternative test is presented, in which algal cultures are used for testing toxic substances. This test system is based on variations in the size distribution of cells in test cultures as a measurement of growth. Thus, inhibition of mitotic activity is used as a measurement for toxic effects. The test can be performed on a short time-scale and is very sensitive to even weak toxic doses.
