Binary Analysis and Period Study of the Long-period, High-mass-ratio Contact Binary KIC 7766185
The Astronomical JournalWe present an in-depth photometric and spectroscopic study of the contact binary KIC 7766185. Spectroscopic observations were conducted on the Mayall 4 m telescope at Kitt Peak National Observatory and used to extract radial velocities.

New Photometric Investigation of the Solar-Type Shallow-Contact Binary HH Bootis
Advances in Astronomy, 2019 The short-period solar-type contact binary HH Boo was monitored photometrically for about 8 years. It is found that the CCD light curves in the B, V, R, and I bands obtained in 2010 are symmetric, while the multicolor light curves observed in 2011 and ...

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors
Advanced Functional Materials, EarlyView.An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...
