中國北方有著很多的鳳凰樹,一入秋冬落葉遍布,然而在清掃處理時除了焚燒處理外,別無他法。而中國齊魯工業(yè)大學(xué)研究者們卻找到一種將落葉轉(zhuǎn)化為多孔碳材料的新方法,這種材料可以用來生產(chǎn)高科技電子產(chǎn)品。
通過將干燥的葉子磨成粉末,高溫處理后產(chǎn)生了一種由微小的碳微球組成的粉末。配以氫氧化鉀腐蝕,進而產(chǎn)生一種表面積非常高的黑色碳粉。經(jīng)檢測,其具有特定的367法拉/克的電容,比一些石墨烯超級電容器的數(shù)值高出三倍以上。
在計算機技術(shù)、混合動力或電動汽車上都或多或少的需要這種超級電容器!怎么樣,萬萬沒想到,這小小的樹葉也能起到大作用吧!
咸水貽貝,大半生都粘附在光溜溜的巖石上,任憑風(fēng)吹浪打紋絲不動。這引起了科學(xué)家們的興趣。近日,生物材料科學(xué)家們就根據(jù)貽貝的特性成功合成新型彈性體材料。
此種材料機械性能極其優(yōu)異,在保持延展性不降低的情況下,剛性和韌性顯著提高。而且擁有十足的粘合能力,足以將不同材料(如木材和金屬)粘合在一起,甚至可以在受損時自行修復(fù)。
平日里的美味貽貝,竟然能用于生產(chǎn)新型材料,真是世界之大無奇不有。據(jù)悉,它們將被用于制造堅韌的生物材料,例如人造肌腱或機器人關(guān)節(jié),以幫助防止磨損。
隨著智能手機的普及化,手機碎屏這種事也就變得司空見慣。那么,世界上有沒有一種屏幕能讓我們告別碎屏噩夢呢?
答案是,有!蘇塞克斯大學(xué)的科學(xué)家們將石墨烯和銀納米線結(jié)合在一起,研發(fā)出更硬、更便宜、更高效的觸摸屏,甚至可以進行彎曲。
“在制作智能手機屏幕的過程中,如果能將石墨烯加入到銀納米線網(wǎng)絡(luò)中,銀納米線網(wǎng)絡(luò)的導(dǎo)電能力也將比原來提升大約1萬倍,”研發(fā)該材料的的團隊負責(zé)人艾倫道爾頓說。使用石墨烯不僅僅只降低了觸控薄膜的成本,它也為智能觸摸屏的研發(fā)帶來了更多的益處。
