Galactic Center Simulation

open access: yes, 2015
We studied the dynamical evolution of the central parsec of the Milky Way, where stars have aspecific structure orbiting the Central Massive Black Hole. We consider that the central parsec consist of a very dense central cluster within the inner-most Arcsec, which is referred as the S-cluster, and two outer orbiting disks.

Early Detection of Cell Death Using Transmembrane Water Exchange Magnetic Resonance Imaging

open access: yesAdvanced Science, EarlyView.
Cell death is important in both the development and treatment of cancer. In this study, it is demonstrated for the first time that a specific measurement of the transmembrane water exchange rate using magnetic resonance imaging can be used as an early marker of cell death in mammalian cells, in animals and in human patients. Abstract Cell death plays a

Mapping Charge Interactions in Intrinsically Disordered Proteins

open access: yesAdvanced Science, EarlyView.
This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

Ferromagnetic Interlayer Exchange Coupling in Magnetic Topological Insulator Sandwich Heterostructures

open access: yesAdvanced Science, EarlyView.
A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...

Uncovering the Lipid Interface in Neurotransmission: Single Molecule Measurements of Neurotransmitters Interacting with Membranes Reveal Species Dependent Membrane Binding

open access: yesAdvanced Science, EarlyView.
Using single‐molecule whispering gallery mode sensors, neurotransmitter‐specific membrane binding signatures are measured that reveal intrinsically distinct interaction kinetics and orientations on a lipid membrane. Abstract Neurotransmitters (NTs) have traditionally been understood to act via aqueous‐phase receptor binding, but growing evidence ...

Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

open access: yesAdvanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.
