显微新技术可在原子尺度上测磁性
显微新技术 原子尺度 磁性
2016/6/22
美国能源部橡树岭国家实验室研究人员与瑞典乌普萨拉大学的同行合作，开发出一种新型电子显微技术，可在原子尺度上检测材料的磁性。研究人员称，这一技术或可为制造体积更小的磁性硬盘驱动器提供新思路。在电子显微技术领域，光学镜头造成的像差是一个让人头疼的问题，像差的扭曲效果会使图像模糊，不利于观测。因此，在过去数十年，研究人员一直想方设法消除各种像差，以求得到更清晰的图像。但此次橡树岭国家实验室和乌普萨拉大学...

新型量子热晶体管 控制热流
2016/6/2
法国普瓦提埃大学和国家科学研究院（CNRS）研究人员设计出一种能像电子晶体管控制电流那样控制热流的量子热晶体管，能从发电站及其他能源系统收集并循环利用余热。目前虽有传输和引导余热的方法，但无法对热流进行有效控制，量子热晶体管做到了这一点。据物理学家组织网23016年5月31日报道，虽然这不是第一个热晶体管，但是第一个由量子物体制造的热晶体管，而其他热晶体管多是用宏观材料如固体或相变材料制造。这种量...
