‏ يهدف البحث إلى تحضير سلسلة جديدة من معقدات العناصر الانتقالية ثنائية التكافؤ (الكوبلت, النيكل, النحاس, الخارصين ‏‏,الكادميوم والزئبق) مع المركبات الحلقية غير المتجانسة (‏L1‎‏) و(‏L2‎‏) والمشتقة من تفاعل 2,1- فينيلين ثنائي امين ‏وسايكلوهكسان -2,1-ثنائي امين مع المركب الوسطي (‏Pr‏) على التوالي. شخصت المعقدات ذات الصيغة العامة :-‏ ‏ ‏‎[M(L1or L2)Cl2]‎‏ بواسطة طيف الرنين النووي المغناطيسي البروتوني والكربوني وقياسات الأشعة تحت الحمراء والطيف ‏الإلكتروني ودرجات الانصهار و التوصيلية المولارية و التحليل الدقيق للعناصر ‏‎ C.H.N.‎والنسبة المئوية للفلز ‏‎%M‏ ‏والحساسية المغناطيسية. استنادا إلى النتائج المعطاه للدراسات المذكورة فقد تم اقتراح الشكل ثماني سطوح للمعقدات المحضرة ‏من خلال ارتباط ذرات النتروجين الاربعة لمجموعة (‏NH‏) في المركبات الحلقية غير متجانسة (‏L1‎‏) و(‏L2‎‏) مع الأيونات ‏الفلزية اضافة الى ايوني الكلور. ‏ ‏ ثم تم تحضير معقد النحاس النانويAuNPs −[CuL1Cl2] ‎‏ من خلط محلول معقد النحاس مع محلول الذهب ‏النانوي‎(AuNPs)‎‏ ، وتم إجراء التشخيص باستخدام طرق مختلفة ، بما في ذلك ‏FTIR‏ و ‏UV-Vis‏ و ‏FESEM‏. تم اختبار ‏قدرة التثبيط للمركبات المحضرة بما في ذلك معقد النحاس النانوي، ضد نوعين من البكتيريا المختارة (‏Escherichia coli‏) ‏والموجبة (‏Staphylococcus aurous‏) بتقنية الانتشار ، حيث أظهرت النتائج أن قدرة المركب النانوي على تثبيط كلا النوعين ‏من البكتيريا كانت أكبر من المركبات الحلقية غير المتجانسة(الليكاندات) ومعقد النحاس الحر, كما‎ ‎تم اختبار معقد النحاس الحر ‏ومعقد النحاس النانوي على خط خلايا سرطان الرئة (‏A456‎‏) وخط الخلايا الطبيعي (‏REF‏) والمقارنة بين المعقدين حيث اظهر ‏معقد النحاس النانوي نتائج ممتازة في امكانية اختباره مستقبلا كعلاج لسرطان الرئة

Praise be to God, Lord of the worlds, and the best of prayers, and extradition was made to our master Muhammad and his whole family and companions:
And after:
Surat Al-Qariah is from the royal fence, which is in the thirtieth part of the Noble Qur’an. The commentators differed on the number of verses, and the reason for its naming. This surah talked about the conditions of people on the Day of Resurrection, and about how people were removed from their graves, all of which I spoke about in the preamble.
The research is divided into six topics: the first topic dealt with strange terms, while the second topic dealt with the most important audio issues mentioned in the surah, namely (slurring, advertising, substitution, and silenc

Kinetic Study of Esterification Reaction
...Show More Authors

The Esterification kinetics of acetic acid with ethanol in the presence of sulfuric acid as a homogenous catalyst was studied with isothermal batch experiments at 50-60°C and at a different molar ratio of ethanol to acetic acid [EtOH/Ac]. Investigation of kinetics of the reaction indicated that the low of [EtOH/Ac] molar ratio is favored for esterification reaction, this is due to the reaction is catalyzed by acid. The maximum conversion, approximately 80% was obtained at 60°C for molar ratio of 10 EtOH/Ac. It was found that increasing temperature of the reaction, increases the rate constant and conversion at a certain mole ratio, that is due to the esterification is exothermic. Activity coefficients were calculated using UNIFAC progra
