Modeling Complex Organic Molecules Formation in Cold Cores: Multi-phase Models with Non-thermal Mechanisms
Yang Lu, Donghui Quan, Qiang Chang +2
In recent years, a significant number of oxygen-bearing complex organic molecules (COMs) have been detected in the gas phase of cold dark clouds such as TMC-1. The formation of the…

Coverage Dependent H Desorption Energy: a Quantitative Explanation Based on Encounter Desorption Mechanism
Qingkuan Meng, Qiang Chang, Gang Zhao +5
Recent experiments show that the desorption energy of H on a diamond-like carbon (DLC) surface depends on the H coverage of the surface. We aim to quantitatively explain th…
