纳米缝合让复合材料更轻更坚韧 该示意图显示了具有复合层的工程材料。碳纤维层(长银管)之间“碳纳米管森林(棕色物体阵列)”。 美国麻省理工学院工程师证明,他们使用新开发的纳米缝合方法可防止复合材料层之...
阅读全文他们在实验室“种”出世界最长石墨烯纳米带 自2004年英国科学家用胶带从石墨层上“撕”出石墨烯并在6年后获得诺贝尔物理学奖以来,这种二维材料已成为备受瞩目的“新材料之王”。 石墨烯具有超高的载流子迁移率,导...
阅读全文基于离子脱嵌反应的传统锂离子电池由于单电子转移产生的比容量有限,其能量密度已接近理论极限,难以满足未来长续航和大规模储能体系的性能需求。三氟化铁正极(FeF3)基于三电子转移的转换反应具备712 mAh g-1的高理...
阅读全文猎豹为猫科动物中非常独特的一个分支,其为追求高速奔跑捕猎而放弃了力量,体现在头部较小,犬牙很小,四肢修长,爪子粗钝不可完全收缩。如此独特的形态特征,使得早年的学者大多把猎豹列为猫科中一个单独的亚科。但后来分...

阅读全文日本NODA SCREEN開發了適用於印刷電路板(PCB)之新型聚氨酯丙烯酸酯(Urethane Acrylate)保護劑,係為無溶劑紫外線(UV)硬化型三防膠(Conformal Coating),具有透明、防水、防滴、防銹等功能。首先將推出黏度分別為100、...
阅读全文日本信越化學工業開發了一項無須使用乳化劑即可維持漆膜特性之水性快速硬化型有機矽樹脂「KRW-6000 Series」。漆膜保留了耐熱性、耐候性等有機矽樹脂的特性,且由於減少了揮發性有機化合物(VOC)與減少溫室氣體(GHG)排...
阅读全文This streamlined approach opens up exciting possibilities for field testing and continuous monitoring. The ability to use a single vial for multiple tests with minimal processing in between could dram...
阅读全文“It is impossible to underscore how excited people are about that tuneability,” Huang says. “The macroscopic twist between the two layers is a really important parameter because as you rotate one o...
阅读全文“This loss mechanism is called “exciton-polaron quenching” and we found that more than half of the light is lost in this way”, Xiaoying continues. The findings of this study therefore imply that d...
