Saynis yahanadu hadda waxay sameeyeen muraayad daaqadeed oo ka caawin karta la dagaalanka wasakhowga gudaha magaalooyinka sida Beijing.Daraasad dhowaan lagu sameeyay caasimadda ayaa muujisay in shaashadaha - kuwaas oo lagu buufiyo nanofibers hufan, wasakhaysan - ay aad waxtar u leeyihiin in lagu ilaaliyo wasakhowga waxyeellada leh ee dibadda, ayuu yiri Scientific American.
Nanofiber-yada waxaa lagu abuuraa iyadoo la adeegsanayo polymers-ka kooban ee nitrogen.Shaashadaha waxaa lagu buufiyaa fiilooyinka iyadoo la adeegsanayo habka dharbaaxada, taas oo u oggolaanaysa lakab aad u khafiif ah oo si siman u daboolaya shaashadaha.
Tiknoolajiyada ka hortagga wasakhowga waa maskax ay iska leeyihiin saynisyahano ka socda labada jaamacadood ee Tsinghua ee Beijing iyo Jaamacadda Stanford.Sida laga soo xigtay saynisyahannadu, maaddadu waxay awood u leedahay inay shaandhayso boqolkiiba 90 wasakhowga waxyeelada leh ee sida caadiga ah dhex mara muraayadaha daaqadaha.
Saynis yahanadu waxay tijaabiyeen shaashado ka hortaga wasakhowga magaalada Beijing intii lagu jiray maalin aad u qiiq badan bishii Disembar.Intii lagu jiray tijaabada 12-saacadood, daaqad hal-iyo-laba mitir ah ayaa lagu qalabeeyay muraayad daaqadeed oo lakabyo leh nanofibers-ka-hortagga wasakhowga.Shaashadda ayaa si guul leh u soo saartay 90.6 boqolkiiba walxaha halista ah.Dhammaadkii tijaabada, saynisyahannadu waxay si fudud u awoodeen inay shaashadda ka tirtiraan walxaha halista ah.
Daaqadahani waxay baabi'in karaan, ama ugu yaraan yareyn karaan, baahida qaaliga ah, nidaamyada shaandhaynta hawada ee tamarta aan waxtarka lahayn, lagama maarmaanka u ah magaalooyinka sida Beijing.
