من إعداد الذكاء الاصطناعي

ابتكر باحثون في جامعة روتشستر نظاماً يعمل بالطاقة الشمسية لتحويل مياه البحر إلى مياه عذبة مع تجنب إنتاج محاليل ملحية سائلة ضارة. وتستخدم هذه التقنية ألواحاً ذات ملمس مُعالج بالليزر لتبخير المياه وتجميع الأملاح على شكل مواد صلبة.

يعتمد النظام على ألواح معدنية سوداء مُعالجة بأشعة الليزر فائقة القصر (فيمتو ثانية) لامتصاص ضوء الشمس وسحب مياه البحر عبر سطح نشط. ومع تبخر المياه، يتم توجيه الأملاح إلى مناطق خاملة باستخدام تأثير حلقة القهوة، مما يمنع حدوث انسدادات أثناء التشغيل. وقد أكدت الاختبارات التي أُجريت على عينات من المحيط الهادئ والأطلسي والهندي استمرارية استخراج المياه العذبة وفاعلية التنظيف الذاتي للنظام.

Nature-inspired “POMbranes” use uniform 1-nanometer pores for ultra-selective molecular filtration

12 يونيو، 2026 من إعداد الذكاء الاصطناعي صورة مولدة بواسطة الذكاء الاصطناعي تم التحقق من الحقائق

Researchers from India and Singapore report a crystalline membrane made from polyoxometalate clusters whose intrinsic openings are about 1 nanometer wide, enabling unusually sharp molecular separations that could help lower energy use in some industrial purification and water-reuse steps.

Researchers create battery-free system for solar fuel production

Scientists at Osaka Metropolitan University have developed an artificial photosynthesis device that converts sunlight, water, and carbon dioxide into formic acid without using batteries. The self-regulating electrolyzer adjusts automatically to changing light levels, simplifying the process and cutting costs.
