Formation of ammonia–helium compounds at high pressure
Nature Communications, 2020 Helium is generally considered too inert to be present in giant ice planet mantles. The authors, by first-principles calculations and crystal structure searches, find stable ammonia–helium compounds at the conditions of Uranus and Neptune’s upper mantles,

Advanced Functional Materials, EarlyView.Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Advanced Functional Materials, EarlyView.High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.

Magnetic Bioprinting and Actuation of Stretchable Muscle Tissue
Advanced Healthcare Materials, EarlyView.Human and murine myoblasts labeled with iron oxide nanoparticles are magnetically bioprinted into wrench‐shaped tissues, which are then anchored between two magnetic needles. Mechanical stretching of these tissues enhances both their maturation and functional performance. Abstract Engineering tissues with precise, long‐lasting shapes and the capability

The Promise of Solid Lubricants for a Sustainable Future
Advanced Materials, EarlyView.Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Giant Planets Can Act As Stabilizing Agents on Debris Disks
, 2017 We have explored the evolution of a cold debris disk under the gravitational influence of dwarf planet sized objects (DPs), both in the presence and absence of an interior giant planet.

Secular Resonances in Planet-hosting Binary Stars. II. Application to Terrestrial Planet Formation
The Astrophysical JournalContinuing our study of the effects of secular resonances on the formation of terrestrial planets in moderately close binary stars, we present here the results of an extensive numerical simulations of the formation of these objects.
