Methane emissions and global warming: Mitigation technologies, policy ambitions, and global efforts

Autor: William Sawyer, Islam Genina, Rebecca Brenneis, Haosheng Feng, Yunpo Li, Shao-Xiong Lennon Luo

Publikováno v: MIT Science Policy Review. 3:73-84

Methane emissions are the second highest contributor to climate change. Despite having a much lower atmospheric concentration than carbon dioxide, anthropogenic methane emissions account for almost one-third of anthropogenic warming since the pre-ind

Assessment of groundwater well vulnerability to contamination through physics-informed machine learning

Autor: Mario A Soriano Jr, Helen G Siegel, Nicholaus P Johnson, Kristina M Gutchess, Boya Xiong, Yunpo Li, Cassandra J Clark, Desiree L Plata, Nicole C Deziel, James E Saiers

Publikováno v: Environmental Research Letters, Vol 16, Iss 8, p 084013 (2021)

Contamination from anthropogenic activities is a long-standing challenge to the sustainability of groundwater resources. Physically based (PB) models are often used in groundwater risk assessments, but their application to large scale problems requir

Effects of ion flux density and energy on the composition of TiNx thin films prepared by magnetron sputtering with an anode layer ion source

Autor: Paul K. Chu, Zhongzhen Wu, Shu Xiao, Ricky K.Y. Fu, Abdul Mateen Qasim, Farhat Ali, Yunpo Li, Hao Wu

Publikováno v: Surface and Coatings Technology. 365:58-64

Titanium nitride films deposited by conventional magnetron sputtering are prone to contamination, especially residual gas species, and the composition and properties can be affected. In this work, an anode layer ion source (ALIS) is used in magnetron

Enhanced mechanical and electrochemical properties of TiNx thin films prepared by magnetron sputtering with an anode layer ion source

Autor: Hao Wu, Ricky K.Y. Fu, Farhat Ali, Abdul Mateen Qasim, Yunpo Li, Paul K. Chu, Zhongzhen Wu, Shu Xiao

Publikováno v: Surface and Coatings Technology. 365:253-260

An anode layer ion source (ALIS) is used in magnetron sputtering to deposit TiN films. The effects of the ion source discharge current (Is) on the microstructure, mechanical, and electrochemical properties, and adhesion characteristics of the deposit
