Influence of water solutions with various pH and electrochemical treatment in cathode position on concentration charge carriers samples Cd x Hg 1-x Te x=0.2-0.3 is investigated. Cathodic cadmium-mercury-tellurium at small density current increases donors, high acceptors are formed. It supposed that hydroxyl groups create centers, introduce interstitial cadmium-mercury-tellurium. At for a long t...
utilization of photodisintegration reaction of deuterium, 2h(?,n)1h, is a precise technique for determining the percentage of 2h in tritiated and natural water. the 23na(n,?)24na reaction is a suitable ?-source for producing the 2h(?,n)1h reaction. tehran research reactor was used as a neutron source for producing 24na isotopes. the bf3 detectors were used to detect the neutron emission of h2 c...
Background and objectives: In the outbreak of infectious diseases, the on time epidemiological, environmental, and laboratorial investigations result in rapid diagnosis of cause and source of the outbreaks and decrease the diseases spread and public health loss. Following the outbreak of gastroenteritis in Pardis Town in January 2014, this research was conducted to identify the cause, source, a...
The pKa of the aqua ligand in complexes of the type trans-[Pt(NH3)2(L)(H2O)] depends on the nature of the ligand trans to H2O, as expected. With L = NH3 or NH2R and n = 2, the pKa is around 6.0 – 6.4. With L = N-heterocyclic ligands generally higher acidities of the aqua ligands are observed, with pKa values being in the range of 4.7 – 5.4. These values are between those for L = H2O, n = 2 (4.4...
