Alireza Pourghaderi

Graduate Student Researcher
Chemical and Biomolecular Engineering
Professor Roya Maboudian (Advisor)
Ph.D. 2026 (Anticipated)

My name is Alireza Pourghaderi and I was born in Shiraz, Iran, in 1997. In 2019, I earned my bachelor's degree in Chemical Engineering from Sharif University of Technology. My B.S. thesis focused mainly on nanomaterials and their environmental applications. I used nanomaterials such as MOFs and Nanodiamond in wastewater treatment applications such as dye adsorption and heavy metal removal. To pursue my academic education, I enrolled in the chemical and biomolecular engineering Ph.D. program at the University of California, Berkeley. Currently, I'm continuing my research on nanomaterials...

BPN913: Mixed-Dye ZIF-8-Based Colorimetric Carbon Dioxide Sensing for Robust Indoor Air Quality Monitoring

Adrian K. Davey
2022

Indoor levels of carbon dioxide (700 parts per million and up), when coupled with volatile organic compounds (VOCs) under most temperature and humidity environments, can induce fatigue, nausea, nasal irritation, and related human health symptoms. Toward the realization of rapid, inexpensive, passive, and visually-obvious indoor gas sensors, we present dye-functionalized metal-organic frameworks (MOFs), which employ distinct color changes to measure indoor carbon dioxide concentrations. Our latest generation of the sensor, based on the coupling of multiple dyes blended with MOF...

BPN914: Elucidating Aging Mechanisms of Tin(IV) Oxide-based Gas Sensors

2022

Despite decades of study and deployment, chemiresistive gas sensors based on SnO2 suffer from baseline drift due to aging of the SnO2 sensing material. In this work, we investigate how repeated, simulated operation of SnO2-based sensors causes irreversible changes in the electronic sensing behavior of SnO2, quantified through the bulk and inter-grain resistance of SnO2 as measured by potentiometric impedance spectroscopy (PIS). In tandem, we apply powder X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) to link the observed changes in the bulk and inter-grain...

BPN968: Metal-Organic Framework Based Triboelectric Nanogenerator for Self-Powered Gas Sensing

Jihoon Chung
Adrian K. Davey

2022

With the rise of interest in the Internet of Things (IoT), the need for low-power sensors for monitoring the working environment has been in spotlight. Considering the number of sensors required to provide real time monitoring, creating sustainable and self-powered sensors is essential. Triboelectric nanogenerator (TENG), which converts mechanical motion to electrical energy, is one of the most promising candidates for realizing self-powered sensors due to its sensitivity to surface material properties and ability to generate consistent signals depending on mechanical input. Here, we...
