Here, we employ in situ electrochemical surface-enhanced Raman spectroscopy (SERS) and density functional theory (DFT) calculation techniques to examine the ORR process at Pt() surfaces. Direct spectroscopic evidence for ORR intermediates indicates that, under acidic conditions, the pathway of ORR at...
Electrochemical measurements in conjunction with in situ Raman analysis displayed that the MXene coating effectively prevented the structural deterioration and irreversible redox mechanism of PPy during the electrochemical analysis. The synthesized MXene@PPy composite when used as a flexible RAB device (Fig...
In a range of neurological conditions, including movement disorders, sex-related differences are emerging not only in brain anatomy and function, but also in pathogenesis, clinical features and response to treatment. In Parkinson disease (PD), for exampl

The in situ Raman spectroscopy analysis and DFT calculations further confirmed that Co sites were the active sites of ORR. This work elucidates that the construction of efficient active centers plays an important role in achieving highly efficient ORR catalysts. Recently, Zhou group reported a new ...
Employing in situ Raman microscopy, they used the vibration of the C-O bond (νC-O) in *CO species as a descriptor to understand the effects of the Cu/Au ratio on the *CO adsorption strength. It was found that with greater Cu coverage, νC-O experienced a red shift, which was ...
A variety of post-mortem MRI approaches have been implemented, including scanning of fixed whole brains or hemispheres [77, 134, 135, 137–140], cor- onal brain slices [141, 142], un-fixed whole brains [134] and brains in situ [143]. Frequently, post-mortem MRI is used for the ...
