6. Unveiling the Journey of Making Single Crystals

   31 Aug 2023 | | Contributor(s):: Ritu Gandhi, Karthik Rao, Rice University

   Growing crystals in saturated solution is a fundamental technique for obtaining well-ordered crystals with controlled properties. This process involves a method called “flux growth”, where single crystals are grown by employing a flux, which is a solvent that facilitates the...

7. Investigating Biomolecular Size Effects on the Performance of Organic Electrochemical Transistors

   31 Aug 2023 | | Contributor(s):: Mariana Prado, Erin Porter, Rice University

   Organic Electrochemical Transistors (OECTs) use biomolecular sensor technology in order to detect biomolecules. These sensors have many advantages such as low cost, ability to amplify molecular binding, and their stability in aqueous environments. OECTs have shown high sensitivity, but there is...

8. Nature of Single-Walled Carbon Nanotubes' Interactions with Differing Photosensitizers

   31 Aug 2023 | | Contributor(s):: Rubiona Grainger, Nima Soltani, Rice University

   It was recently discovered that when Single-Walled Carbon Nanotubes (SWCNTs) wrapped with single-stranded DNA are exposed to singlet oxygen the singlet oxygen reacts with the guanine nucleotides embedded in the DNA. The singlet oxygen is produced by irradiation of a photosensitizer. However,...

9. Sustainable and Energy Efficient Removal of PFAS-Saturated Granular Activated Carbon

   31 Aug 2023 | | Contributor(s):: Melody Jenkins, Sara Denison, Rice University, NEWT Center

   Currently water treatment plants remove toxic PFAs using granular activated carbon (GAC) but have no sustainable process for disposing PFAS. Our approach focuses on the successful removal and destruction of PFAs in GAC preventing contaminants from entering back into the environment & uses...

10. Cell Factory for Small Molecule Inducible Delivery of Low Dose IL-2

    31 Aug 2023 | | Contributor(s):: Celsa Pachlhofer, Yafet Arefeayne, Rice University

    Autoimmune and inflammatory diseases are characterized by insufficient regulatory T cells (Treg), which play a central role in maintaining peripheral tolerance, preventing autoimmunity, and limiting chronic inflammation.  Treg cells depend on IL-2 for survival and maintenance of their...

11. Food Web Differences in Primary Versus Secondary Growth in a Lowland Tropical Rainforest

    31 Aug 2023 | | Contributor(s):: Patricia Juarez Swan, Annie Finneran, Rice University

    Biodiversity of wildlife can be seen in interactions between species, such as predation. One way to understand predation between animals such as mammals and birds are food webs, which documents which animals eat each other. Understanding how humans can impact these food webs, and therefore the...
