वैज्ञानिकों का नया कारनामा : ऐसी रेत जो उपकरणों को जल्दी ठंडा कर सकेगी

103

lअमेरिका के वैज्ञानिकों ने एक ऐसी सफ़ेद रेत विकसित की है जो इलेक्ट्रॉनिक उपकरणों को जल्दी ठंडा कर सकेगी । पोलिमर की परत सिलिकॉन डायऑक्साइड नैनोपार्टिकल्स होते हैं।

वैज्ञानिकों के मुताबिक, सिलिकॉन डायऑक्साइड से खुद ठंडा रखने का काम नहीं होता । किन्तु परत चढ़ी नैनोस्केल सिलिकॉन डायऑक्साइड की खासियत से ऐसा हो जाता है. अभी उपलध हीट कम करने वाले तत्वों की तुलना में यह ज्यादा प्रभावशाली तरीके से ठंडा करने का काम करता है।

एथिलीन ग्लाइकोल का प्रयोग वाहन के एंटीफ्रीज में भी किया जाता है। एथिलीन ग्लाइकोल ठीक तरह से काम तो करता है लेकिन वह भाप बन जाता है। जार्जिया इंस्टीट्यूट ऑफ टेक्नोलॉजी के एसोसिएट प्रोफेसर बारातुंडे कोला ने बताया कि हम पोलिमर पदार्थ का पता लगा रहे हैं जिसे सिलिकॉन डायऑक्साइड नैनोपार्टिकल सोख सके। यह बिजली से चलने और अधिक गर्म होने वाले इलेक्ट्रॉनिक, एलईडी और अन्य उपकरणों की ठंडा करने में उपयोगी साबित हो सकता है। वैज्ञानिकों ने गर्मी करने वाले पदार्थ के तौर पर एथिलीन ग्लाइकोल का इस्तेमाल किया जो बिजली का संवाहक नहीं होता।
