synthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand

در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Ecological Semiotics: A Set of Problems and Some Biosemiotic Traditions

The biological stability of natural groups (populations) of mammals under natural conditions is maintained by behavioral mechanisms based on the information-communicative interactions of individuals. Small predator mammals leading a lonely life, such as the red fox (Vulpes vulpes), and the marten family representatives – pine marten (Martes martes), ermine or short-tailed weasel (Mustela ermine...
