Effect of pre-existing shear bands on the tensile mechanical properties of a bulk metallic glass
Abstract Bulk Zr64.13Cu15.75Ni10.12Al10 metallic glass has been rolled at room temperature in two different directions, and the dependences of microstructure and tensile mechanical property on theExpand

The effects of surfactants on the heterogeneous uptake of sulfur dioxide on hematite
Abstract Surfactants are often found to be associated with atmospheric particles. They can change the physicochemical properties of these particles, and thereby impact their chemical reactivity.Expand

Design and measurement of a single-dual-band tunable metamaterial absorber in the terahertz band
Abstract In this paper, a single-band tunable metamaterial absorber with metal disk array is verified in Terahertz (THz) range. An absorption peak Is achieved based on local surface plasmon (LSP)Expand
Characteristics of air pollution episodes influenced by biomass burning pollution in Shanghai, China
Abstract In the atmosphere, biomass burning can interact with other pollution sources and thereby aggravate air pollution. However, its influences on the occurrence and development of air pollutionExpand
The Door Is Closed, but Not Locked: China's VPN Policy
This paper attempts to explain why China still allow some people to use Virtual Private Networks (VPNs) to bypass China’s heavily guarded Internet content censorship system, despite the assumptionExpand
