3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

Advanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets. II. The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model

The Astrophysical Journal
Although dust constitutes only about 1% of the mass in a protoplanetary disk, recent studies reveal its substantial impact on the torques experienced by low- and intermediate-mass planetary cores.

The First Direct Distance and Luminosity Determination for a Self-Luminous Giant Exoplanet: The Trigonometric Parallax to 2MASS1207334-393254Ab

, 2007
We present the first trigonometric parallax and distance for a young planetary mass object. A likely TW Hya cluster member, 2MASSW J1207334-393254Ab (hereafter 2M1207Ab) is an M8 brown dwarf with a mid to late L type planetary mass companion.

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

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 ...

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 ...

Study on SMA driven hopper design for planetary exploration

Nihon Kikai Gakkai ronbunshu, 2018
This paper studies the feasibility of a hopper for planetary exploration rovers. The proposed hopper is designed based on shape memory alloy(SMA) actuators, because SMA actuators are light in mass compared with traditional electric motors.

Star-planet magnetic interaction and evaporation of planetary atmospheres

, 2013
Stars interact with their close-in planets through radiation, gravitation, and magnetic fields. We investigate the energy input to a planetary atmosphere by reconnection between stellar and planetary magnetic fields and compare it to the energy input of ...
