Localization of Key Technologies and Devices for Neutron Detectors
The reporter learned from the Dongguan Research Department of the Institute of High Energy Physics of the Chinese Academy of Sciences that recently, the Chinese spallation neutron source detector team successfully prepared high-performance and large-area boron carbide films, realizing the localization of key technologies and devices of neutron detectors.High performance large area boron carbide thin film sample...

Why is there such a significant difference in value between gold and iron, which are both composed of the same protons, neutrons, and electrons?
Gold and iron are metals with different values, but even children know that gold is relatively expensive. Otherwise, how could one say that an inch of time is an inch of gold? These two values have a huge difference, but the true essence is not much different, because there is no difference between the protons, neutrons, and electrons that make up gold and iron atoms!What are substances composed of?The electron should be the earliest particle found in the atom...
