For instance, per the US Department of Energy's ARPA-E estimates, developing a standalone alloy that could continuously operate at $1300^oC$ has the potential to increase gas turbine efficiency up to $7\%$, significantly reducing wasted energy, and consequently carbon emissions, saving up to 20 quads of energy in electricity generation and civilian aviation between now and 2050 \cite{ULTIMATEArpa-e.energy.gov}. Such efficiency increase could prevent the release of approximately 1,000,000,000,000 kg of \ch{CO_2} from burning natural gas, or double that from coal; thus, becoming a critical effort in fighting global warming in applications, like airplanes, where green technologies cannot be directly adapted. -Secondly, such alloys are of great interest to the society.

Another extreme environment application, quite far from the first one, is the class of hypersonic vehicles that travel faster than 5 times the speed of sound \emph{through Earth's atmosphere for extended periods of time}, thus generating extreme sustained temperatures within structural components. This prompts the need for novel materials and engineering techniques, as evidenced by massive funding assigned to this research area by the US military, which increased its yearly budgets for hypersonic \emph{research} from \$3.8 billion in FY2022 to \$4.7 billion in FY2023, and to an undisclosed amount this year (FY2024) \cite{Sayler2024HypersonicCongress}, further demonstrating the criticality of such materials. +Another extreme environment application, quite far from the first one, is the class of hypersonic vehicles that travel faster than 5 times the speed of sound \emph{through Earth's atmosphere for extended periods of time}, thus generating extreme sustained temperatures within structural components.

Thus, research into such materials may also one day enable an entirely green future, and has recently been endorsed in this direction by the United States White House \cite{}. \section{Flow of Material Discovery and This Work} \label{intro:sec:flow} diff --git a/main.tex b/main.tex index 4d861f6..cfbbc17 100644 --- a/main.tex +++ b/main.tex @@ -319,7 +319,7 @@ \chapter*{Vita} After earning his B.S.E. degree in 2019, he moved directly to pursue PhD at Penn State under world-renowned thermodynamics expert Prof. Zi-Kui Liu and had the pleasure of working on implementing a variety of computational techniques, including machine learning, while having the support of colleagues who are specialists in ab-initio modeling, thermodynamic calculations, and materials discovery.
