瑞典查尔莫斯大学研究人员能够用一种新的显微技术来观察单个纳米粒子,而不是观察聚集在一起混杂不清的一团粒子。发表在《自然·材料》杂志上的成果显示,研究人员利用等离子激光纳米光谱电子成像技术实现了对单个钯纳米粒子的观察。实验发现,尽管纳米粒子具有相同的大小和形状,但在4 kPa的大气 Researchers at Chalmers University in Sweden can use a new microscopy technique to look at individual nanoparticles instead of looking at a bunch of particles that get together. Published in the “Nature · Materials” magazine results show that researchers using plasma laser nanoscopic imaging technology to achieve a single observation of palladium nanoparticles. Experiments found that, although the nanoparticles have the same size and shape, but in 4 kPa atmosphere
