ما يعرفه ريفو عن الخبر

  • طور باحثون بجامعة توهوكو اليابانية مادة كهروحرارية من نيتريد الكروم لتحويل الحرارة المفقودة من الأجهزة إلى كهرباء.
  • أدت إضافة التيتانيوم إلى تقليل العيوب في المادة ورفع عامل قدرتها الكهروحرارية بمقدار 250 ضعفا.
  • تمكن الباحثون من إنتاج المادة في صورة أغشية رقيقة عند درجة حرارة الغرفة باستخدام تقنية الترسيب بالرش التفاعلي.
  • أظهرت النتائج تحسناً في حركة الإلكترونات وزيادة في جودة تحويل فرق درجات الحرارة إلى أداء كهربائي.

طوّر باحثون بجامعة توهوكو اليابانية مادة رقيقة من نيتريد الكروم مُعزَّزة بالتيتانيوم، رفعت عامل القدرة الكهروحرارية 250 مرة، مقارنة بالمادة النقية.
