A novel, mixed-valent copper(I)-copper(II) complex, {[bis(ethylene-diamine)copper(II)] bis[diiodocuprate(I)]} (1), has been prepared by electrochemical dissolution of a sacrificial copper anode in a solution of ethylenediamine (en), I2 and tetraethylammoniumperchlorate (TEAP) as supporting electrolyte in acetonitrile (AcN)and characterized by single-crystal X-ray structure determination. The cr...

cases every year, and it is 4.5% of all cancers.By 2017 data HPV prevalence in Turkey 67.6%. High-risk types cause the development cervix, vulva, oropharynx, esophagus, penis, anal cancers. Fortunately, we have methods preventing cancer formation. The most effective method vaccination. There are three prophylactic vaccines: 4vHPV (quadrivalent), 2vHPV (bivalent), 9vHPV (nonavailable).The purpos...

Cations of the alkali earth group have strong tendencies to form partially dissociated complexes in solution with the anions of carboxylic acids and other weak acids. The affinity of this association tends to increase with the number of carboxylic acid groups of the acid anion. In a considerable number of cases the effect has been studied quantitatively and expressed in terms of well defined di...

metal ions are the main impurities of water and media ingredients used in fermentation processes. in this research, the effect of ca+2, co+2, cu+2, fe+2, mg+2, mn+2 and zn+2 as chloride and sulfate salts was studied on the clavulanic acid production and streptomyces clavuligerus growth. all chloride salts had negative effect on clavulanic acid production and no clavulanic acid was produced in t...
