In the room temperature and nitrogen conditions, we presented well-resolved absorption spectra and indexes of refraction of bactericide molecules in the far infrared radiation (FIR) spectral region recorded by terahertz time-domain spectroscopy (THz-TDS). As illustrative examples we discussed the absorption spectra of captan and folpet in THz region. The absorption coefficient and index of refr...
This paper describes the status of the 2012 edition of the HITRAN molecular spectroscopic compilation. The new edition replaces the previous HITRAN edition of 2008 and its updates during the intervening years. The HITRAN molecular absorption compilation is comprised of six major components structured into folders that are freely accessible on the internet. These folders consist of the tradition...
wheat starch is the most common type of starch in iran as well as many other parts of the world with enormous applications in food and non-food products. to improve its physicochemical properties or create new functionalities, starch can be modified by changing its molecular structure. amongst different methods for starch modification, physical methods have received more attention recently. pre...
background: zinc (zn) as an important trace element is essential for testicular development and spermatogenesis. molecular mechanism of zn action in the reproductive system may be related to metal binding low-molecular weight proteins, metallothioneins (mt). our objective was to determine the effect of zn on two important isoforms of mt, mt1m and mt1g genes expression on testicular sertoli cell...
Optical spectroscopy techniques, including visible and near infrared (IR) Raman and synchrotron IR methods have been applied to study solid nitrogen at megabar pressures. We find that nitrogen becomes totally opaque above 150 GPa, accompanied by the disappearance of Raman and IR vibrational excitations, while new broad IR and Raman bands become visible. Optical absorption measurements reveal th...
