Origin of water in PDS 70 At the typical densities of inner disk regions (nH ≥ 108 cm−3) the chemistry can rapidly reach steady-state conditions and water vapour can form from a simple reaction sequence involving O, H2and OH. Water and OH absorb efficiently in the ultraviolet (...
Pd atoms coordinate with four Se atoms to form a square backbone network. Monolayer PdSe2 has been successfully exfoliated by Akinola D. Oyedele et al. for the first time, which provides exciting opportunities for the research of pentagonal 2D materials18. The air-stability and anisotropy of ...

the densities of the d-orbital state of the Pd atom and the p-orbital state of the Se atom change. This leads to a change in the orbital space configuration and orbital hybridization. This is the cause of the transformation in the form of the bandgap. The change in the form of the ba...
Qujing City. Consisting of patches of limestone peaks, and covering an area of hundreds of square kilometers, it is the essence of the karst landform. The height of the peaks ranges from 10 to 100 meters, with shapes of turriform, taper and round. Viewed from distance, those densely distr...
