Chemical and Materials Engineering Faculty Publications

Antifreeze peptides inhibit ice crystal growth and recrystallization, and are promising components of cryoprotective formulations for cell, tissue, and food preservation, as well as anti-icing surface coatings. However, the discovery of new antifreeze peptides has been hindered by their sequence diversity and the limited scalability of experimental screening. In this study, we identify novel antifreeze peptide candidates from a microbiome-derived sequence library using ensemble machine learning and molecular dynamics (MD) simulations. We developed an ensemble classifier composed of 10 adapter-tuned protein-language models and a random forest meta-learner. After training on a curated dataset of 73 766 sequences, we applied this …

Functionalization Of Microfiltration Media Towards Catalytic Hydrogenation Of Selected Halo-Organics From Water, Subrajit Bosu, Samuel S. Thompson, Doo Young Kim, Noah D. Meeks, Dibakar Bhattacharyya

Chemical and Materials Engineering Faculty Publications

Contaminated water detoxification remains difficult due to the presence of persistent halo-organic contaminants, such as perfluorooctanoic acid (PFOA) and chlorophenols, which are chemically stable and resist conventional purification methods. Functionalized membrane-based separation and decontamination have garnered immense attention in recent years. Commercially available microfiltration membrane (PVDF) and polymeric non-woven fiber filters (glass and composite) are functionalized with poly(methacrylic acid) (PMAA) that shows outstanding pH-responsive performance and tunable water permeability under ambient conditions perfect for environmental applications. Polymer loading based on weight gain measurements on PMAA–microglass composite fibers (137%) and microglass fibers (116%) confirmed their extent of functionalization, which was significantly …

Hydrogel Nanoparticle Synthesis Using Liquid–Solid Separation For A More Efficient, Greener Process, Emily N. Ingram, Jason Stallings, Mara Leach-Baughman, Endras Fadhilah, Anastasia Shaverina, Brittany E. Givens, Malgorzata Chwatko

Chemical and Materials Engineering Faculty Publications

Water swollen nanoparticle synthesis methods have been fine-tuned and universally used to create materials in the medical and cosmetic industries. However, these methods often utilize toxic solvents and generate excess waste during the separation and purification processes. This work presents a protocol using an inverse nanoemulsion wherein liquid–liquid separation is replaced with liquid–solid separation, i.e. crystallization to isolate nanoparticles. Using low toxicity oils that are solids at room temperature, water-in-oil nanoemulsions can be generated at elevated temperatures, and upon removal of heat, solid–liquid separation isolates nanoparticles in the aqueous phase. Poly(ethylene glycol) diacrylate (PEG-DA) was chosen to create polymer nanogels …

Ion Diffusion Overestimates Figures Of Merit In Polymeric Mixed Conductors, Maryam Shahi, Vianna N. Le, Paula Alarcon Espejo, Bowen Ding, Joel H. Bombile, Chad Risko, Martin Heeney, Alexandra F. Paterson

Chemical and Materials Engineering Faculty Publications

Figures of merit are used to translate science to technology. For organic mixed ionic–electronic conductors (OMIECs), the product of mobility and volumetric capacitance, i.e., the µC* product, is the figure of merit used to guide the development of technologies ranging from bioelectronics to neuromorphics. While organic electrochemical transistors (OECTs) are used extensively to measure the µC* product, if there is a kink in the transistor current, then the µC* product is overestimated. Here, we show that the origin of the kink is a change in the rate with which the ions diffuse into the channel. We also discover that the …

Stochastic Mechanical Mesoscale Modeling Of Cylindrical Cavities In Metallic Foams, Mujan N. Seif, Alexandre Martin, Matthew J. Beck

Chemical and Materials Engineering Faculty Publications

Aluminum foam is a critical component of state-of-the-art micrometeoroid and orbital debris shielding. However, its randomly oriented constituent ligaments create significant variability in properties at different length scales. Previous efforts have thoroughly characterized the statistical implications of micro- to macro-scale-length transitions on the homogenized elastic behavior of damage-free, pre–micrometeroid and orbital debris (MMOD) strike structures. In this work, the properties of the residual material post MMOD impact are assessed by introducing cylindrical cavities representing the damage track. It was observed that configuring the cavity parallel to the through-the-thickness direction transformed a nominally isotropic foam into an anisotropic (transverse isotropic) material, …

Effect Of Protective Mutation On Structure And Dynamics Of Apoe: A Molecular Dynamics Simulation Study, Newton A. Ihoeghian, Usman L. Abass, Ibrahim A. Imam, Qing Shao

Chemical and Materials Engineering Faculty Publications

Apolipoprotein E (APOE) plays a significant role in determining the risk of Alzheimer’s disease (AD). Three mutations—APOE3–R136S, APOE3–V236E, and APOE4–R251G—have been reported to reduce the risk of AD. Unveiling the molecular mechanism behind this reduction could lay a foundation for developing therapeutics for AD. To shed light on this subject, we investigate the mutation-induced variation in structural and dynamic properties of APOE3–R136S, APOE3–V236E, and APOE4–R251G in explicit solvent using molecular dynamics simulations. The APOE2, APOE3, and APOE4 were used as the reference. The analysis unveiled that the three protective mutations may exert protection through different mechanisms. The R215G mutation makes …

Chemical and Materials Engineering Faculty Publications

Microplastics are becoming increasingly abundant waste products; therefore, the risk of human exposure is also increasing. The cytotoxic consequences of microplastic exposure, particularly in cancer, have yet to be explored. We obtained commercially available polystyrene nanoparticles of uniform size (86.61 ± 6.41 nm) and confirmed the chemical composition and shape using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), respectively. We evaluated colloidal stability over a range of concentrations from 1–1000 µg mL⁻¹ using hydrodynamic diameter and zeta potential, determining that higher concentrations exhibit greater colloidal stability compared to lower concentrations. Specifically, the zeta potential increased from …

The Essence Of The Heart: Layered Human Experience In Eva Jessye’S My Spirituals, Jessica Brunet

Theses and Dissertations--Music

Much of the spiritual repertory has been transcribed as documentation of purely melodic and lyrical content, and many songs have been arranged by some of the greatest figures in twentieth- and twenty-first century music history, including Harry T. Burleigh, Hall Johnson, Margaret Bonds, and Jacqueline B. Hairston. On this roster of luminaries is Dr. Eva Jessye (1895-1992).

If Eva Jessye is remembered at all, it is typically in the context of her role as choral director for the original production of Gershwin’s Porgy and Bess (1935). Among a litany of other accomplishments, however, Dr. Jessye also published a collection of …

Red Clover Isoflavones And Establishment In The Context Of Tall Fescue Toxicosis Mitigation In The Mid-South, Jonathan L. Stephens

Theses and Dissertations--Plant and Soil Sciences

Low levels of red clover (Trifolium pratense L.) have been shown to mitigate tall fescue (Lolium arundinaceum (Schreb.) toxicosis symptoms. This is because of the presence of plant-produced compounds known as isoflavones. Production of a red clover supplement on a commercial scale would require industrial-level processing of raw plant material into granules or pellets. The first study of this thesis evaluated the impact of drying temperature on bioavailability of isoflavones. Drying temperatures up to 104°C had minimal impact on isoflavone concentrations. Additionally, varietal differences in isoflavone concentrations were documented. The second study of this thesis evaluated optimal establishment …
