Lee Y, Heuston A, Jin E, Sun J, Liang X, Zhu Y, et al.
Langmuir . 2025 Feb; 41(6):3995-4004. PMID: 39901800
Chemical upcycling of polyethylene (PE) to long-chain alkylaromatics through tandem hydrocracking/aromatization has potential to provide value-added chemicals. However, the liquid product is a complex mixture of alkanes, alkylbenzenes, and polyaromatics,...

Marlowe J, Deshpande S, Vlachos D, Abu-Omar M, Christopher P
J Am Chem Soc . 2024 May; 146(20):13862-13874. PMID: 38738663
Catalysts containing Pt nanoparticles and reducible transition-metal oxides (WO, NbO, TiO) exhibit remarkable selectivity to aromatic products in hydrodeoxygenation (HDO) reactions for biomass valorization, contrasting the undesired aromatic hydrogenation typically...

Liu B, Westman Z, Richardson K, Lim D, Stottlemyer A, Gillis P, et al.
ACS Macro Lett . 2024 Mar; 13(4):435-439. PMID: 38546447
Polyurethane (PU) is the sixth most used plastic in the world. Because many PU derived materials are thermosets and the monomers are valuable, chemical recycling to recover the polyol component...

Liu B, Westman Z, Richardson K, Lim D, Stottlemyer A, Farmer T, et al.
ACS Sustain Chem Eng . 2024 Mar; 12(11):4435-4443. PMID: 38516400
Chemical recycling of polyurethane (PU) waste is essential to displace the need for virgin polyol production and enable sustainable PU production. Currently, less than 20% of PU waste is downcycled...

Lamb J, Lee Y, Sun J, Byron C, Uppuluri R, Kennedy R, et al.
ACS Appl Mater Interfaces . 2024 Feb; 16(9):11361-11376. PMID: 38393744
Supported platinum nanoparticle catalysts are known to convert polyolefins to high-quality liquid hydrocarbons using hydrogen under relatively mild conditions. To date, few studies using platinum grafted onto various metal oxide...

Lee Y, Sun J, Scott S, Abu-Omar M
STAR Protoc . 2023 Sep; 4(4):102575. PMID: 37729056
Depolymerization and upcycling are promising approaches to managing plastic waste. However, quantitative measurements of reaction rates and analyses of complex product mixtures arising from depolymerization of polyolefins constitute significant challenges...

ACS Macro Lett . 2022 May; 10(9):1167-1173. PMID: 35549075
Direct lithium extraction via membrane separations has been fundamentally limited by lack of monovalent ion selectivity exhibited by conventional polymeric membranes, particularly between sodium and lithium ions. Recently, a 12-Crown-4-functionalized...
