Film Thickness and Surface Plasmon Tune the Contribution of SFG Signals from Buried Interface and Air Surface
Liang Zhang, Junjun Tan, Quanbing Pei, and Shuji Ye
Sum frequency generation vibrational spectroscopy (SFG-VS) is a powerful technique for determining molecular structures at both buried interface and air surface. Distinguishing the contribution of SFG signals from buried interface and air surface is crucial to the applications in devices such as microelectronics and bi

Unveiling Defect-Mediated Carrier Dynamics in Few-Layer MoS2 Prepared by Ion Exchange Method via Ultrafast Vis-NIR-MIR Spectroscopy
Zhen Chi, Hui-hui Chen, Zhuo Chen, and Hai-long Chen
Defect-mediated processes in two-dimensional transition metal dichalcogenides have a significant influence on their carrier dynamics and transport properties, however, the detailed mechanisms remain poorly understood. Here, we present a comprehensive ultrafast study on defect-mediated carrier dynamics in ion exchange p

Designer Mg?Mg and Zn?Zn Single Bonds Facilitated by Double Aromaticity in the M2B7- (M=Mg, Zn) Clusters
Wei Wang, Jie Wang, Chu Gong, Chaonan Mu, Dongmei Zhang, and Xinxing Zhang
The simple homodinuclear M$ - $M single bonds for group II and XII elements are difficult to obtain as a result of the fulfilled s$ ^2 $ electronic configurations, consequently, a dicationic prototype is often utilized to design the M$ ^+ $$ - $M$ ^+ $ single bond. Existing studies generally use sterically bulky organi

Photodynamics of Methyl-Vinyl Criegee Intermediate: Different Conical Intersections Govern the Fates of Syn/Anti Configurations
Ya-zhen Li, Jia-wei Yang, Lily Makroni, Wen-liang Wang, and Feng-yi Liu
Methyl vinyl ketone oxide, an unsaturated four-carbon Criegee intermediate produced from the ozonolysis of isoprene has been recognized to play a key role in determining the tropospheric OH concentration. It exists in four configurations ($ anti $-$ anti $, $ anti $-$ syn $, $ syn $-$ anti $, and $ syn $-$ syn $) due t

Direct Observation of Transient Species Generated from Protonation and Deprotonation of the Lowest Triplet of p-Nitrophenylphenol
Jing Long, Zhao Ye, Yong Du, Xu-ming Zheng, and Jia-dan Xue
Photo-induced proton coupled electron transfer (PCET) is essential in the biological, photosynthesis, catalysis and solar energy conversion processes. Recently, $ p $-nitrophenylphenol (HO-Bp-NO2) has been used as a model compound to study the photo-induced PCET mechanism by using ultrafast spectroscopy. In transient a
