چکیده
condensation of glyoxal, formaldehyde and anilines lead to the formation of 2,4,6,8- tetraphenyl and substituted phenyl 2,4,6,8-tetraazabicyclo [3.3.0] octanes. the reactions are sensitive to ph and temperature. ortho derivatives of anilines do not participate in this condensation. x-ray structural determination reveals a cis-dienvelope geometery about the two fused rings.

متن کاملSex determination by the length ratio of metacarpals and phalanges: X-ray study on Iranian population
Background: In forensic anthropological identification, we usually use body remains. Accurate sex estimation from these remains is very important and needs the knowledge of specific population standards of that area. Sometimes, human remains are damaged by environmental circumstances. So, we must examine single bones for sex estimation. One of the relatively resistant bones to environmental con...
متن کاملSynthesis and characterization of Gd2O2 S: Tb3+ phosphor powder for X-ray imaging detectors
Gadolinium oxysulfide phosphor doped with trivalent terbium have been synthesized using urea homogenous precipitation and followed by sulfurization at 800 °C under argon atmosphere. Structural and morphological of synthesized phosphor powder were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Hexagonal structure ...
