Xinchen Wang
Xinzheng () is a county-level city of Henan Province, China. It is under the administration of the prefecture-level city of Zhengzhou, the provincial capital. The city has a population of 600,000 people and covers an area of , of which is urban. History Xinzheng is considered one of the birthplaces of the Chinese nation. More than 8000 years ago, neolithic people of Peiligang culture lived in the vicinity. The legendary Yellow Emperor was said to have been born in Xinzheng 5000 years ago. During the Zhou dynasty it was the capital of the state of Zheng and later, the state of Han, after the conquest of the former by the latter. It was the seat of government for the Qin dynasty, from about 221 BCE, which is considered the beginning of a unified China. The word ''qin'' (), which is pronounced similar to "chin", is thought to be the basis for the word "China." Historically, this prefecture was an integrated part of Zhengzhou. However, in 1994, the Henan Provincial Council authoriz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qing Dynasty
The Qing dynasty ( ), officially the Great Qing,, was a Manchu-led imperial dynasty of China and the last orthodox dynasty in Chinese history. It emerged from the Later Jin dynasty founded by the Jianzhou Jurchens, a Tungusic-speaking ethnic group who unified other Jurchen tribes to form a new "Manchu" ethnic identity. The dynasty was officially proclaimed in 1636 in Manchuria (modern-day Northeast China and Outer Manchuria). It seized control of Beijing in 1644, then later expanded its rule over the whole of China proper and Taiwan, and finally expanded into Inner Asia. The dynasty lasted until 1912 when it was overthrown in the Xinhai Revolution. In orthodox Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multiethnic Qing dynasty lasted for almost three centuries and assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 the f ...

Han (state)
Han (, Old Chinese: ''*'') was an ancient Chinese state during the Warring States period of ancient China. It is conventionally romanized by scholars as Hann to distinguish it from the later Han dynasty (). It was located in central China (modern-day Shanxi and Henan) in a region south and east of Luoyang, the capital of the Eastern Zhou. It was ruled by a royal family who were former ministers in the state of Jin that had slowly gained power from the Jin royal family until they were able to divide Jin into the three new states of Han, Wei and Zhao with the assistance of two other ministerial families. The state of Han was small and located in a mountainous and unprofitable region. Its territory directly blocked the passage of the state of Qin into the North China Plain.. Although Han had attempted to reform its governance (notably under Chancellor and " Legalist" Shen Buhai who improved state administration and strengthened its military ability) these reforms were not e ...

Lihe
LiHe is a compound of helium and lithium. The substance is a cold low-density gas made of Van der Waals molecules, each composed of a helium atom and lithium atom bound by van der Waals force. The preparation of LiHe opens up the possibility to prepare other helium dimers, and beyond that multi-atom clusters that could be used to investigate Efimov states and Casimir retardation effects. Detection It was detected in 2013. Previously 7Li4He was predicted to have a binding energy of 0.0039 cm−1 (7.7×10−8eV, 1.2×10−26J, or 6 mK), and a bond length of 28 Å. Other van der Waals-bound helium molecules were previously known including Ag3He and He2. Detection of LiHe was done via fluorescence. The lithium atom in the X2Σ state was excited to A2Π. The spectrum showed a pair of lines, each split into two with the hyperfine structure of 7Li. The lines had wavenumbers of 14902.563, 14902.591, 14902.740, and 14902.768 cm−1. The two pairs are separated by 0.177&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
