Encapsulation of vitamin D3 in pickering emulsions stabilized by nanofibrillated mangosteen cellulose: Impact on in vitro digestion and bioaccessibility
Thunnalin Winuprasith,Piyachai Khomein,Wiphada Mitbumrung,Manop Suphantharika,Anadi Nitithamyong,David Julian McClements +5 more
TL;DR: This article used nanofibrillated cellulose (NFC) to stabilize oil-in-water emulsions, and showed that NFC has a minor effect on lipid digestion and bioaccessibility when used at relatively low levels.
Journal ArticleDOI
Modulating absorption and charge transfer in bodipy-carbazole donor–acceptor dyads through molecular design
John Strahan,Bhooshan C. Popere,Piyachai Khomein,Craig A. Pointer,Shea M. Martin,Amanda N. Oldacre,Sankaran Thayumanavan,Elizabeth R. Young +7 more
TL;DR: Several possible synthetic paradigms to tune photophysical properties with directed synthetic modifications are revealed and a mechanistic understanding of the ground- and excited- state behavior in these small-molecule donor-acceptor dyads is provided.
Journal ArticleDOI
Oligomers as Triggers for Responsive Liquid Crystals
Young-Ki Kim,Krishna R. Raghupathi,Joel Pendery,Piyachai Khomein,Uma Sridhar,Juan J. de Pablo,Juan J. de Pablo,Sankaran Thayumanavan,Nicholas L. Abbott +8 more
TL;DR: Insight is provided into the rational design of oligomers that can be used as triggers to create responsive LCs and proof-of-concept experiments of the triggering of LCs using a trimeric amphiphile that is photocleaved by UV illumination into monomeric fragments are provided.
Journal ArticleDOI
Photophysical and Electrochemical Characterization of BODIPY-Containing Dyads Comparing the Influence of an A-D-A versus D-A Motif on Excited-State Photophysics.
Samuel J. Hendel,Ambata Poe,Piyachai Khomein,Youngju Bae,Sankaran Thayumanavan,Elizabeth R. Young +5 more
TL;DR: Steady-state and time-resolved photoluminescence augment the insights from TA, while electrochemistry and spectroelectrochemistry are employed to identify the nature of the excited state and provide contextualization for structure-function relationships between molecules and OPV devices.
Journal ArticleDOI
BODIPY dyads and triads: synthesis, optical, electrochemical and transistor properties
TL;DR: It is found that the D–A–D triads exhibited broader absorption, raising the HOMO energy levels and increase hole carrier mobilities, and that BODIPY containing carbazole demonstrated smooth film and no macro phase aggregation was observed upon thermal annealing.
