中国科学院深圳先进技术研究院专利：计算SPACE序列信号的方法和系统及主动脉信号的采集方法
The French Alternative Energies and Atomic Energy Commission (CEA) is conducting two feasibility studies on nuclear propulsion for the European Space Agency, which could pave the way for missions to M...
Westinghouse Electric Company and lunar landers and rovers developer Astrobotic have signed a memorandum of understanding to explore collaboration on space technology programmes for NASA and the US De...
The HEARTS project will provide two new radiation-testing facilities for space applications, one at CERN and one at GSI in Germany. The project started in January and will allow the testing of high-en...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Maximal $L^1$-regularity and application to a free boundary problem of Navier-Stokes equations near half-space in critical space (I)
临界空间 近半空间 纳维-斯托克斯方程 最大$L^1$-正则性 自由边界问题

Bangor University in Wales will develop a nuclear thermal fuel system to support deep space exploration with funding provided by the UK Space Agency. It is one of eight projects receiving a total of G...
At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given Cornell researchers fresh insight into something...
If faced with the choice of sending a swarm of full-sized, distinct robots to space, or a large crew of smaller robotic modules, you might want to enlist the latter. Modular robots, like those depicte...
If deep space exploration is to become a reality, humans will need to be as self-sufficient as possible. Since ordering supplies from Earth won’t be practical, the astronauts will have to fabricate th...
In the future, mass transportation will almost certainly involve self-driving vehicles. The aerospace industry is pushing that idea even further, all the way to space, but the results for autonomous s...
中国科学院大连化学物理研究所揭示无机/有机界面三线态能量转移的“Through-space”与“Through-bond”机制（图）
无机/有机界面 三线态 能量转移 Through-space Through-bond 机制
2020/8/24
近日，中国科学院大连化学物理研究所光电材料动力学特区研究组研究员吴凯丰团队，通过同时调控无机半导体纳米晶的波函数分布和表面受体分子的构型，采用时间分辨光谱，观测到无机/有机界面三线态能量转移中的“Through-space”与“Through-bond”机制，并基于此实现高效的分子三线态敏化和三线态湮灭的光子上转换。近年来，无机纳米晶到有机分子的三线态能量转移被发展为一种新型、高效的分子三线态敏化...
近日，北京大学地球与空间科学学院宗秋刚教授与邹鸿副教授领导的联合团队受邀为Space Weather杂志撰写论文，介绍团队自主研发的北大-成像电子谱仪及其科学价值。该文被Space Weather杂志遴选为当期专题文章（Featured Article）并登上封面。北大-成像电子谱仪（BD-IES）是北京大学空间物理与应用技术研究所自主研发的新一代空间科学载荷，其设计新颖、测量可靠，高能量与时空分...
