Since human corneal endothelial cells are not known to reproduce, their evaluation assumes para mount importance in light of the recent increase in in traocular lens (IOL) implantation. Earlier work has been carried out in the area of protecting

An electron-spin-resonance study of pure copper phthalocyanine single crystal reveals a highly anisotropic environment. There are strong exchange and dipolar interactions between equivalent sites. However, the exchange interactions between the two no

The applicability of the band model to explain conduction in metal‐free phthalocyanine is suggested by the equality of the thermal acrivation energy for electrical conduction, the energy for first optical absorption, and the energy for the initiati

The trapping spectrum of pure and doped triphenylene has been explored. Photocurrent vs. intensity dependences previously obtained are found to be due to traps detected by double beam illumination. These traps cover a range from 1.1 eV to 1.5 eV abov

The Hall effect and conductivity of zinc oxide have been measured in dense polycrystalline samples and two single crystals.It has been found that the usual simple Wilson semiconductor model is inadequate for the proper interpretation of results. Seve

A systematic study of the photoconductive properties of pure and doped triphenylene films and crystals has been made to determine the involvement of the singlet and triplet states of both host and guest in the conduction process. The guest molecules
