Perioperative identification of ischemic-hypoxic tissue is essential for reducing the risk of mastectomy skin flap necrosis (MSFN), a major complication following mastectomy. Implant-based breast reconstruction is jeopardized in the presence of MSFN. However, existing technologies are limited by depth insensitivity, dye-related risks, the need for contact sensors, and an inability to simultaneously assess both blood flow and oxygenation. A multi-wavelength speckle contrast diffuse correlation tomography (MW-scDCT) system was developed for noncontact, dye-free, and depth-sensitive imaging of tissue hemodynamics in a rat model incorporating four distinct flap scenarios: sham (SH), implant (IM), half necrosis (HN), and full necrosis (FN), representing varying …

Singlet fission (SF) and triplet–triplet annihilation (TTA) are processes which may be exploited to boost the efficiency of solar energy technology. Despite being studied since the late 1960s, the mechanism of singlet fission is still not fully understood. This is partly because the main technique used to study singlet fission, optical or visible/near-IR transient absorption spectroscopy, cannot distinguish between the strongly coupled triplet-pair state1(TT), weakly interacting triplet pairs (T..T), and independent triplet states T1+ T1. To solve this problem, we combine transient optical spectroscopy performed as a function of magnetic field and transient electron …

Chemistry Faculty Publications

Lignans are small polyphenolic compounds that play an active role in plant defense against pathogens and predators. Recently, lignan machilin D was reported to be effective as an anti-tumorigenic agent in triple negative breast cancer (TNBC) tumor-bearing mice. Previous studies have relied on plant-extracted material limiting scalability and diversification of the natural scaffold. Herein, we describe a generalizable one-pot synthesis of machilin D and its derivatives via an iron chloride-induced dimerization of isoeugenol. Employing this synthetic methodology allowed for a robust diversification campaign to access seven (7) new lignan derivatives of the machilin D family with superior anti-proliferative properties in …
