A Possible Explanation of W-type Phenomena in V694 Peg
The Astrophysical JournalThree sets of complete multicolor light curves of V694 Peg observed in 2013, 2015, and 2019 were presented and analyzed. Our photometric solutions show that this system was an A-type shallow contact binary in 2013 and 2015 while it converted to a W-type ...

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2
Advanced Functional Materials, EarlyView.A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.

Contact tracing of binary stars - from sub-solar to high-mass components
, 2022 Stellar mergers produce massive single stars with potentially distinctive prop- erties. These include rejuvenated blue stragglers, highly magnetized (massive) stars, and stars with peculiar chemical abundances and rotation rates. The actual merger phases

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

The First Multicolour Photometry of The V840 Lyr Contact Binary Star
Revista Mexicana de Astronomía y AstrofísicaLight curves for the total-eclipsing binary system V840 Lyr in the V, Rc, and Ic bands are presented; these display the O'Connell effect. Analysis was performed with the Phoebe031a software revealing that V840 Lyr is a W-type contact binary with a degree of contact factor of f = 15.1 ± 5.6%, a mass ratio of q = 0.4509 ± 0.0705, an inclination of i = 86.

Advanced Functional Materials, EarlyView.Combined UV–vis transmittance and wavelength‐dependent photo‐assisted DC I–V analyses reveal defect‐induced optical instability and a high density of deep donor‐like subgap traps in La‐doped SrSnO3. The resulting MOSFET achieves one of the highest on/off ratios reported for ABO3 perovskite devices, demonstrating the promise of stannate perovskites as ...
