Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

Advanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Asymmetric Temperature Variations In Protoplanetary Disks. I. Linear Theory, Corotating Spirals, and Ring Formation

The Astrophysical Journal
Protoplanetary disks can exhibit asymmetric temperature variations due to phenomena such as shadows cast by the inner disk or localized heating by young planets. We investigate the disk features induced by these asymmetric temperature variations. We find

Influence of Ion Size on Structure and Redox Chemistry in Na‐Rich and Li‐Rich Disordered Rocksalt Battery Cathodes

Advanced Materials, EarlyView.
The larger ion size of Na+ versus with Li+ has a pronounced impact on the intercalation chemistry of disordered rocksalt cathode materials. On charge, the disordered rocksalt structure is retained in Li2MnO2F but it is lost in Na2MnO2F resulting in extensive amorphization.

Mid-infrared Spectrum of the Disk around the Forming Companion GQ Lup B Revealed by JWST/MIRI

The Astrophysical Journal Letters
GQ Lup B is a forming brown dwarf companion ( M ∼ 10–30 M _J ) showing evidence for an infrared excess associated with a disk surrounding the companion itself.

Formation Of Planetesimals And Planets

, 2018
In this Bridge Talk, we intend to summarize our current understanding of planetesimal and planet formation. For planetesimal formation, we will emphasize recent theoretical and laboratory work on the evolution of dust in protoplanetary disks. We will discuss possible pathways towards planetesimals and their consequences on planetesimal properties ...

Ancestral Protein‐Based Lighting

Advanced Materials, EarlyView.
The ancestral sequence reconstruction (ASR) method applied to a large dataset of modern fluorescent proteins (FPs) led to a bright ancestral‐like FP suitable for photon down‐conversion in bio‐hybrid light‐emitting diodes (Bio‐HLEDs). Abstract Protein‐optoelectronics is a paradigm toward eco‐designed and sustainable technologies.

JWST/MIRI Detection of a Carbon-rich Chemistry in the Disk of a Solar Nebula Analog

The Astrophysical Journal
It has been proposed, and confirmed by multiple observations, that disks around low-mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their hotter, more massive solar counterparts.

Astrophysics of Planet Formation [PDF]

, 2009
The study of planet formation has been revolutionized by recent observational breakthroughs, which have allowed the detection and characterization of extrasolar planets, the imaging of protoplanetary disks, and the discovery of the Solar System's Kuiper Belt.
