The photoluminescence spectra of porous silicon and their temperature dependences and transformations on aging are studied. It is shown that the infrared band prevailing in the spectra of as-prepared samples is due to exciton recombination in silicon

We consider a new type of nonradiative transitions in nonmetallic solids. The transitions are not accompanied by heat release but by large (compared with interatomic distances) displacements of individual atoms. These instabilities (electrostatic, vi

1-(N-piperidine-acetyl)-2,3-dihydroindoles display high activity in infiltration and conduction anestheia, exceeding that of trimecaine. N-alkylaminoacetyl-indolines are moderately active, while N-morpholine and N-indolylacetyl-indolines are practica

The change in the photosensitivity of CdS:Cu crystals caused by photochemical reactions was used to record a holographic grating. A phase grating was obtained having a diffraction efficiency controlled by the intensity of the readout beam.
