Abstract Boosting carrier mobility is essential for achieving high room-temperature thermoelectric performance in n-type Bi2Te3-based films, which have long exhibited inferior power factors compared with their single crystal counterparts due to poor carrier mobility. To overcome this challenge, we develop a simple substrate surface engineering strategy to fabricate Twin-free n-type Bi2Te3 (000 l) thin films.

Abstract Mg3Bi2-xSbx compounds have emerged as promising mid-temperature thermoelectric materials, due to their excellent electrical performance and the ultralow thermal conductivity. In this study, we investigate the complex phonon interactions in Mg3Bi2-xSbx compounds and reveal nontrivial symmetry-protected topological crossings and avoided-crossing phenomena in the phonon dispersion, arising from the strong coupling between the acoustic and low-energy optical phonons.

Abstract Inflammatory bowel disease (IBD) is a debilitating condition driven by the dual pathologies of chronic inflammation and impaired intestinal barrier function. A significant clinical need exists for therapies that can effectively target both issues simultaneously. In this study, we investigated the therapeutic potential and mechanism of 5-hydroxy-N,N,N-trimethyltryptamine (5-OH-TMT), a quaternary ammonium salt derivative of bufotenine.
