Science classrooms (even in the time of the pandemic) should provide more challenging, inquiry-based, authentic and higher-order learning experiences allowing students to participate in scientific practices and tasks. Rich scientific databases, e-Learning tools and digital educational resources can serve as a catalyst for science learning. They can offer a better understanding of complex scientific research, making science understandable and interesting to the students.
科学教室(即使在大流行期间)应提供更具挑战性、以探究为基础、真实和高阶的学习体验,使学生能够参与科学实践和任务。丰富的科学数据库、电子学习工具和数字教育资源可以成为科学学习的催化剂。他们可以更好地理解复杂的科学研究,使科学对学生来说更容易理解和有趣。

S. Heim
The Higgs boson was discovered at the Large Hadron Collider in 2012. Since then, a comprehensive program has been ongoing to characterize it as precisely as possible. Can this particle help us solve some of the big open questions in physics?

Perovskite Solar Mini-Modules 钙钛矿太阳能微型组件
Q4 Physics and Astronomy Pub Date : 2021-01-01 DOI: 10.1051/epn/2021501
A. Bruno
In the last decade perovskite solar cells have shown remarkable improvements in power conversion efficiency which have driven the interest to commercialise the perovskite technology. Here, I will present an overview of our recent works focused on the development and the understanding of highly efficient co-evaporated perovskite solar cells with excellent thermal stability and remarkable upscalability. Our works demonstrate the compatibility of perovskite technology with consolidated industrial processes and its potential for next-generation photovoltaics on the market

Breaking the millikelvin barrier in nanoelectronics 打破纳米电子学中的毫开尔文势垒
Q4 Physics and Astronomy Pub Date : 2021-01-01 DOI: 10.1051/epn/2021406
R. Haley, J. Prance, D. Zumbühl
In labs across Europe physicists are pushing the boundaries of how far we can cool the electrons in nano-fabricated circuits and quantum-enhanced devices. The cryogen-free revolution in dilution refrigeration has liberated researchers from a reliance on helium, a costly and non-renewable resource, and hugely expanded the numbers of cooling machines available for new science and quantum technology applications which exploit the properties of materials at kelvin and millikelvin temperatures.
在欧洲各地的实验室里,物理学家们正在推动我们在纳米制造电路和量子增强设备中冷却电子的极限。无低温的稀释制冷革命使研究人员摆脱了对氦的依赖,这是一种昂贵且不可再生的资源,并极大地扩展了用于新科学和量子技术应用的冷却机器的数量,这些冷却机器可以利用开尔文和毫开尔文温度下材料的特性。

Cryogenic Dark Matter Searches 低温暗物质搜索
Q4 Physics and Astronomy Pub Date : 2021-01-01 DOI: 10.1051/epn/2021304
L. Baudis
In the decades-old quest to uncover the nature of the enigmatic dark matter, cryogenic detectors have reached unprecedented sensitivities. Searching for tiny signals from dark matter particles scattering in materials cooled down to low temperatures, these experiments look out into space from deep underground. Their ambitious goal is to discover non-gravitational interactions of dark matter and to scan the allowed parameter space until interactions from solar and cosmic neutrinos are poised to take over.
在几十年来揭开神秘暗物质本质的探索中,低温探测器已经达到了前所未有的灵敏度。这些实验从地下深处观察太空,寻找暗物质粒子散射在冷却到低温的材料中的微小信号。他们雄心勃勃的目标是发现暗物质的非引力相互作用,并扫描允许的参数空间,直到来自太阳和宇宙中微子的相互作用准备好接管。

J. Pekola
Low temperature phenomena and methods are quantum thermodynamics per se. Modern engineered quantum systems, for instance those used for superconducting quantum information processing and mesoscopic electron transport, provide working media for realizing devices such as quantum heat engines and refrigerators and a testbed for fundamental principles and phenomena in thermodynamics of quantum systems and processes.
