Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

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...

Spring 2024
This work aims to conduct a techno-economic feasibility analysis of adopting a hybrid approach to hydrogen generation. This includes grey hydrogen sourced from natural gas using Steam Methane Reforming (SMR) and green hydrogen from renewable energy. The key focus is on assessing the environmental...

Spring 2020
On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...
