Dependence of Multiband Absolute Magnitudes and Color Indexes of the Tip of the Red Giant Branch Stars on Metallicity in Galactic Globular Clusters

open access: yesThe Astrophysical Journal
The tip of the red giant branch (TRGB) stars have attracted intensive attention in recent years because their I -band absolute magnitudes, M _I , are often used for distance calibration in the Hubble constant measurements because of its almost ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

open access: yesAdvanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Heteronanoarchitecture of Ti3C2Tx MXene and Amorphous MOF for Exceptional Durability in Electro‐Ionic Soft Actuator

open access: yesAdvanced Materials, EarlyView.
The nanoscale hybridization of MXene and amorphous metal‐organic framework (MXene–aMOF) achieves exceptional electrochemical stability and ion storage capacity, attributed to the synergistic interplay between the nanoporous surfaces of aMOF and the metal‐like electron conduction of MXene.
