Mechanisms And Applications Of Improved Protein Analysis By Desorption Electrospray Ionization Mass Spectrometry (Desi-Ms), Roshan Javanshad

Dissertations

Electrospray ionization mass spectrometry (ESI-MS) is a soft ionization technique that allows detection of macromolecules, such as intact proteins, by the formation of multiply charged ions from solutions. Desorption electrospray ionization mass spectrometry (DESI-MS) is an ambient ionization technique that directly samples analyte from a surface during ESI-MS analysis. Although DESI-MS is highly accomplished at the analyses of metabolites, lipids, and other small molecules, it is far more limited when it comes to protein analysis. While most of the field in ambient ionization MS has moved towards primarily applications, our approach has been to explore the use of DESI-MS and …

A Contribution To The Study Of Flow Field And Heat Transfer On A Rearward - Facing Step., Awad El-Hadik Dec 2021

A Contribution To The Study Of Flow Field And Heat Transfer On A Rearward - Facing Step., Awad El-Hadik

Mansoura Engineering Journal

The flow and convective heat transfer characteristics over a backward-facing step were investigated numerically and experimentally. Two different step-heights were studied for different Reynolds numbers. The point of reattachment of the flow behind the step proved to be the point of maximum heat transfer coefficient. The size of the separated region as well as the Nus sell number depended greatly on the Reynolds number. Downstream of reattachment, the heat transfer coefficient declined rapidly and followed gradually the contour of the turbulent hound ary layer. The results of the investigation were compared to others from the literature with sat-isfaction.
