An attractive field of plasmon-mediated chemical reactions (PMCRs) is developing rapidly, but there still incomplete understanding how to control the kinetics such a reaction related hot carriers. Here, we chose 8-bromoadenine (8BrAd) as probe molecule electrons investigate influence electrode potential, laser wavelength, and power on PMCR silver nanoparticle-modified electrodes. Plasmonic electron-mediated cleavage C–Br bond in 8BrAd has been investigated by combining situ electrochemical...
Interpersonal emotion regulation (IER) is a crucial ability for effectively recovering from negative emotions through social interaction. It has been emphasized that the empathy network, cognitive control and affective generation network sustain deployment of IER. However, temporal dynamics functional connectivity among these networks IER remains unclear. This study utilized task-fMRI sliding window approach to examine both stationary dynamic (dFC) Fifty-five healthy participants were...
Abstract Metabolic imaging has been widely used to measure the early responses of tumors treatment. Here, we assess abilities PET measurement [18F]FDG uptake and MRI hyperpolarized [1-13C]pyruvate metabolism detect changes in glycolysis following treatment-induced cell death human colorectal (Colo205) breast adenocarcinoma (MDA-MB-231) xenografts mice. A TRAIL agonist that binds but not mouse cells induced tumor-selective death. Tumor was assessed by injecting [1,6-13C2]glucose measuring...
Surface plasmon resonance (SPR) bridges photonics and photoelectrochemistry by providing an effective interaction between absorption confinement of light to surface electrons plasmonic metal nanostructures (PMNs). SPR enhances the Raman intensity enormously in surface-enhanced spectroscopy (SERS) leads plasmon-mediated chemical reaction on nanostructured electrodes. To observe variations reactivity selectivity, we studied photoelectrochemical reactions para-aminobenzoic acid (PABA) gold The...
Magnetic Resonance Spectroscopy (MRS) is a noninvasive tool to reveal metabolic information. One challenge of <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> H-MRS the low Signal-Noise Ratio (SNR). To improve SNR, typical approach perform large number Signal Averaging (SA). The data acquisition time, however, proportional SA accordingly. A complete clinical MRS scan takes approximately 10 minutes in common setting with 128. Recently,...
