Mössbauer study of sputtered Fe‐Ti alloys with wide composition range

Composition range of binary amorphous alloys.

Structure of Sputtered Amorphous Zr-Hf-Si Alloys

Amorphous (Zr,Hf)37Si63 alloys were produced by sputtering. Their total structure factors were determined by X-ray diffraction. Using the methods of isomorphous substitution and Reverse Monte Carlo simulation, the partial pair correlation functions were obtained. The results were compared with the partial functions of amorphous Ti40Si60. In the amorphous alloys under investigation the transitio...

Thymoquinone: an emerging natural drug with a wide range of medical applications

Nigella sativa has attracted healers in ancient civilizations and researchers in recent times. Traditionally, it has been used in different forms to treat many diseases including asthma, hypertension, diabetes, inflammation, cough, bronchitis, headache, eczema, fever, dizziness and influenza. Experimentally, it has been demonstrated that N. sativa extracts and the main constituent of their vola...

Phase separation in sputtered amorphous metal-germanium alloys.

Anomalous small-angle x-ray scattering (ASAXS) has been used to observe and characterize phase separation in sputtered amorphous FecGel -c and MocGe 1-c thin films. Significant chemical inhomogeneity and anisotropy is observed. At low metal concentrations (c<O.25), no . .. .. -films are homogeneous nor isotropic through the metal-insulator transition composition region (10<cs25). Measurements p...

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 ...
