Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

Advanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

MAGNETIC COUPLING IN THE DISKS AROUND YOUNG GAS GIANT PLANETS [PDF]

, 2013
We examine the conditions under which the disks of gas and dust orbiting young gas giant planets are sufficiently conducting to experience turbulence driven by the magneto-rotational instability.

Bismuthene Under Cover: Graphene Intercalation of a Large Gap Quantum Spin Hall Insulator

Advanced Materials, EarlyView.
Bismuthene, a quantum spin Hall insulator with a massive 800 meV topological gap, holds great potential for room‐temperature devices but rapidly degrades in air. This study demonstrates that intercalating bismuthene between SiC and a graphene sheet preserves its structure and topology while preventing oxidation, enabling ex‐situ experiments and ...

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,

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.

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 ...

Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering

Advanced Materials, EarlyView.
Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

Suppressing Metal Dissolution in Multi‐Grained Catalysts Through Intragrain Atomic Ordering for Stable Fuel Cells

Advanced Materials, EarlyView.
This study presents a novel approach room‐temperature ultrasound assisted atomic ordering method using to fabricate multi‐grained NiPt nanoalloys with an intermetallic Ni3Pt5 phase. The resulting catalyst exhibits state‐of‐the‐art durability and activity in all operational condition of proton exchange membrane fuel cells. Structural and electrochemical

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.

Dual‐Selective Terahertz‐Nanodisc Metasurfaces for Exploring Neurotransmitter Dynamics beyond Spectral Limitations

Advanced Materials, EarlyView.
Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with
