Anomalous Dissociative Capture Cross Section at the Interaction of Singly Charged Ions with Molecules of Nucleic Acid Bases

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Cross Section Ratios for the Electron Impact Production of Singly and Multiply Ionized Rare Gas Ions

Experim ental da ta on electron im pact ionization of gaseous species are of great in terest for predicting and understanding the properties of nonequilibrium plasmas, cf. e.g. ref. [1], However, even for the rare gases discrepancies between published partia l ion­ ization cross section ratios am ount to more th an a factor of 2. The present paper is devoted to precise measurements of partia l ...

Single Electron Capture in Slow Collisions of Doubly Charged Ions with Dinuclear Molecules

We have performed translational-spectroscopical measurements on single electron capture (SEC) by impact of slow (impact energy ≤ 1 keV) doubly charged ions on dinuclear molecules. For impact of C and N ions the influence of their metastable fractions on the SEC probability has been studied. For impact of He on O2 and CO direct and dissociative SEC have been investigated. For all collision syste...

the in silico insight into carbon nanotube and nucleic acid bases interaction

conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...
