The atomic path for constructing single‐helical superstructure of AuCu bimetallic nanoclusters
Aggregate, 2023 Single‐helical or double‐helical structures are common in living organisms. Helical assembly has been found in the artificial nanoparticles, but how they do so remains poorly understood. Here, we exploit atomically precise Au6Cu6 bimetallic nanoparticles

Potential of big data approach for remote sensing of vehicle exhaust emissions
Scientific Reports, 2021 At present, remote sensing (RS) is applied in detecting vehicle exhaust emissions, and usually the RS emission results in a definite vehicle specific power (VSP) range are used to evaluate vehicle emissions and identify high-emitting vehicles.

Non-linear influences of the built environment on transportation emissions: focusing on densities [PDF]
, 2017 Compact development is often recommended to reduce auto-dependency thereby decreasing related energy consumptions and transportation emissions. However, there could be a non-linear relationship between density and transportation emissions because of a ...
