Novel Co-Precipitation method for synthesis of Nanostructured Nickel Oxide in accordance to PH: Structural and Optical Properties as an Active optical filter

Low cost Co-Precipitation method was used for Preparation of novel nickel oxide (NiO) nano particle thin films with Simple

with two different PH values 6

12 and its effect on structural and optical properties as an active optical filter. Experimental results of structural properties X-ray diffraction (XRD) showed that both Nickel oxide nanoparticles with (PH=6 and 12) have polycrystalline structure smaller average particle size about 8.5 nm for PH=6 in comparison with PH=12. Morphological studies using Scanning electron microscopy (SEM) and atomic force microscope (AFM) show uniform nano rod distribution for PH=6 with smaller average diameter

average roughness as compared with NiO with PH=12 that showed larger diameter

الرؤية الصينية للتقارب الأمريكي مع تايوان في إدارة الرئيس جو بايدن

أظهر التصعيد الاخير في منطقة جنوب شرق آسيا

أن المنطقة مقبلة على أزمات سياسية واقتصادية وعسكرية

من خلال قيام الولايات المتحدة وحلفاؤها بفرض عقوبات اقتصادية تجاه الصين

وواقع التصعيد العسكري قد يبدأ مع غزو الصين لتايوان

لاسيما وأن ثلثي القوات الأمريكية في العالم تتواجد في مضيق تايوان وبحر الصين الجنوبي. تدعي الولايات المتحدة بأنها مستعدة للدفاع عن جزيرة تايوان في حالة بدء العمليات العسكرية الصينية

لكن ما يظهر هو دعم الولايات المتحدة لتايوان عسكرياً

من خلال تجهيزها بالأسلحة الحديثة للدفاع عن نفسها. ودعم تايوان اقتصادياً من خلال زجها في اتفاقيات تجارية مع دول حليفة للولايات المتحدة في المنطقة مثل اليابان وكوريا الجنوبية والهند واستراليا للتعزيز من نفوذها وهيمنتها

ولردع التوجهات الاستراتيجية الصينية في المنطقة. أما سياسياً فأن الكونغرس اجاز قانون اعادة الاتصالات مع تايوان

والدليل زيارة رئيسة مجلس النواب الأمريكي (نانسي بيلوسي)

التي كادت أن تُشعل مواجهات عسكرية بين الولايات المتحدة والصين.

Synthesis, Characterization and Stability Study of V(IV), Zr(IV), Rh(III), Pd(II), Cd(II) and Hg(II) Complexes with Pyrazol Derivative

In this work lactone (1) was prepared from the reaction of p-nitro phenyl hydrazine with ethylacetoacetate

which upon treatment with benzoyl chloride afforded the lactame (2). The reaction of (2) with 2-amino phenol produced a new Schiff base (L) in good yield. Complexes of V(IV)

in addition to magnetic susceptibility and conductivity measurements. Metal to ligand [M:L] ratio was obtained for all complexes in ethanol using molar ratio method

which gave comparable results with those obtained for the solid complexes. As well as the appa
