Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

Functional surface nanodroplets for sensitive chemical analysis and nanomaterials synthesis
DownloadSpring 2022
Surface nanodroplets are nano-scale droplets immobilized on a solid surface with an immiscible liquid environment. These droplets possess a large surface area to volume ratio and some desirable properties such as a long lifetime and excellent stability, compared to the bulk droplets. Surface...

Spring 2021
Asphaltenes are the heaviest and most polar group of molecules in crude oil. Colloidal behaviors of asphaltenes, including the aggregation and interfacial behaviors, have impacts on many petroleum production processes. For example, the aggregation of asphaltenes can lead to problems such as...
