When it comes to good conductors, cement is usually not the first material you’d think

當你在找一個好的導電體時，水泥通常不會是第一個出現在你腦中的選項

of…until now. Scientists at the University of Alicante have recently developed cement

...直到現在。在阿利坎特大學的科學家最近發展出一種水泥

that has the ability of conducting both heat and electricity efficiently and without compromising

具有有效率導電和導熱的能力，同時不需犧牲一半水泥所具有的

the strength that normal cement provides. While electricity conducting cement may not

seem like a “mind-blowing scientific achievement” it has huge applications for places like airports

不像一個「令人興奮的成就」，但它在許多地方像是機場和

and roads to prevent ice or snow build-up. Not only can the cement exist on its own,

道路上被使用來防止結冰或這積雪具有殺手級的應用。不只能夠以水泥的形式存在，

it can also be used as a coating on existing cement to give it heat and electric conductivity.

它也可以被用來塗在其他水泥表面上，賦予原本基礎水泥導電和導熱特性。

atoms would clump together forming a “super atom”. All of the same properties are retained,

and insanely slippery coating that can have wide applications even outside the realm of

，且不可思議地滑順塗層，能夠廣泛地被應用，即使是用在食品調味

condiments. While it’s not the first “superhydrophobic” material ever invented, it is the first non-toxic
