Thermionics in Topological Materials

Advanced Materials, EarlyView.
Thermionics is one of the fundamental energy conversion mechanisms in solid state systems. Recent development in topological materials opens new avenues in developing thermionic systems and devices. Due to the linear energy dispersion and topological protection of charge transport, these new materials are promising candidates for high efficiency ...

Metallicity of the Massive Protoplanets Around HR 8799 If Formed by Gravitational Instability

, 2009
The final composition of giant planets formed as a result of gravitational instability in the disk gas depends on their ability to capture solid material (planetesimals) during their 'pre-collapse' stage, when they are extended and cold, and contracting ...

Understanding the Role of Borohydride Doping in Electrochemical Stability of Argyrodite Li6PS5Cl Solid‐State Electrolyte

Advanced Materials, EarlyView.
This study reveals how LiBH4 doping in argyrodite‐type Li6PS5Cl solid‐state electrolyte improves electrochemical stability by forming a tri‐layer SEI based predominately on Li3P/LiBH4/Li2S that promotes ion transport and blocks electrons. In situ XPS and TOF‐SIMS show thinner SEI, enhanced Li electrodeposition, and better interfacial wetting compared ...

Closed‐Loop and Sustainable 4D Printing of Multi‐Stimuli‐Responsive Sulfur‐Rich Polymer Composites for Autonomous Task Execution

Advanced Materials, EarlyView.
Closed‐loop and sustainable 4D printing of sulfur‐rich polymer composites is demonstrated for the first time using loosely crosslinked poly(phenylene polysulfide) networks (PSNs) and their magnetic composites (MPSNs). 3D‐printed PSNs and MPSNs exhibit shape‐morphing capabilities and can be directly reprinted into new form factors and magneto‐responsive

2-D numerical experiments of thermal convection of highly viscous fluids under strong adiabatic compression: implications on mantle convection of super-Earths with various sizes

Earth, Planets and Space
We conduct a series of numerical experiments of thermal convection of compressible fluids with temperature-dependent viscosity, in order to study how the adiabatic compression and model geometries affect the mantle convection on super-Earths.

Young planets under extreme UV irradiation. I. Upper atmosphere modelling of the young exoplanet K2-33b

, 2017
The K2-33 planetary system hosts one transiting ~5 R_E planet orbiting the young M-type host star. The planet's mass is still unknown, with an estimated upper limit of 5.4 M_J. The extreme youth of the system (

Delineating the Triphasic Side Reaction Products in High‐Energy Density Lithium‐Ion Batteries

Advanced Materials, EarlyView.
Triphasic side reaction products—gaseous, soluble, and solid CEI—formed at the interface between high‐Ni cathodes and carbonate‐based electrolytes have been quantitatively analyzed with online electrochemical mass spectrometry (OEMS), nuclear magnetic resonance (NMR) spectroscopy, and X‐ray photoelectron spectroscopy (XPS), systematically elucidating ...
