Unperceivable Designs of Wearable Electronics

Advanced Materials, EarlyView.
Unperceivable wearable technologies seamlessly integrate into everyone's daily life, for healthcare and Internet‐of‐Things applications. By remaining completely unnoticed both visually and tactilely, by the user and others, they ensure medical privacy and allow natural social interactions.

Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides

Advanced Materials, EarlyView.
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

A Resonant Beginning for the Solar System’s Terrestrial Planets

The Astrophysical Journal
In the past two decades, transit surveys have revealed a class of planets with thick atmospheres—sub-Neptunes—that must have completed their accretion in protoplanet disks.

Multiarm spirals on the periphery of disc galaxies

Open Astronomy, 2018
Spiral patterns in some disc galaxies have two arms in the centre, and three or more arms on the periphery. The same result is also obtained in numerical simulations of stellar and gaseous discs.We argue that such patterns may occur due to fast cooling ...

The Long-Lasting Activity in the Flat Spectrum Radio Quasar (FSRQ) CTA 102

Galaxies, 2019
The flat spectrum radio quasar CTA 102 ( z = 1 . 032 ) went through a tremendous phase of variability. Since early 2016 the gamma-ray flux level has been significantly higher than in previous years. It was topped by a four month long giant outburst,

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Shapeshifting Nanocatalyst for CO2 Conversion

Advanced Materials, EarlyView.
A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.
