Abstract

[المشكلة] يتعلق الاختراع الحالي بتوفير طريقة جديدة لإنتاج جسيم نانوي يشتمل على جسيم معدنين يحتوي على أكسيد حديد يرتبط به واحد أو أكثر من المركبات الترابطية الآلفة للماء تناسقيًا، حيث يكون الجسيم النانوي مفيدًا كعامل تباين للتصوير بالرنين المغناطيسي. [وسيلة للحل] كالطريقة الجديدة لإنتاج جسيم نانوي يشتمل على جسيم معدني يحتوي على أكسيد حديد يرتبط به واحد أو أكثر من المركبات الترابطية الآلفة للماء تناسقيًا، بإجراء تبادل مركب ترابطي بمركب ترابطي آلف للماء من جسيم أكسيد حديد نانوي له سطح يرتبط به مركب ترابطي غير آلف للماء تناسقيًا في خطوة واحدة باستخدام محفز انتقال طور، يمكن توقع تقصير عمليات الإنتاج وتقليل المركبات الترابطية الآلفة للماء المستخدمة. علاوة على ذلك، بإنتاج جسيم أكسيد حديد نانوي له سطح يرتبط به مركب ترابطي غير آلف للماء تناسقيًا باستخدام طريقة إضافة قطرة قطرة، يمكن تجنب ارتفاع درجة الحرارة السريع والتفاعل عند درجة حرارة عالية تبلغ 200 ْم أو أعلى، وهو أكثر فائدة للإنتاج الصناعي.
