A Robust Study of High-redshift Galaxies: Unsupervised Machine Learning for Characterizing Morphology with JWST up to z ∼ 8

The Astrophysical Journal
Galaxy morphologies provide valuable insights into their formation processes, tracing the spatial distribution of ongoing star formation and encoding signatures of dynamical interactions.

Taming Interfacial Ion‐Dipole Interactions With d‐Orbital Delocalized Electron Catalysis Expediates Low‐Temperature Li Metal Batteries

Advanced Materials, EarlyView.
The ion‐dipole interactions within Li(solvents)x+ groups for fast interfacial Li+ desolvation/diffusion and dendrite‐free deposition are reduced by taming various d‐orbital electron‐delocalized catalyzers under the low‐temperature surroundings.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Exploring Quasar Variability with ZTF at 0 < z < 3: A Universal Relation with the Eddington Ratio

The Astrophysical Journal
Quasars, powered by accretion onto supermassive black holes (SMBHs), exhibit significant variability, offering insights into the physics of accretion and the properties of the central engines.

2dF QSO Redshift Survey

, 2000
With approximately 6000 QSO redshifts,the 2dF QSO redshift survey is already the biggest complete QSO survey. The aim for the survey is to have 25000 QSO redshifts, providing an order of magnitude increase in QSO clustering statistics. We first describe the observational parameters of the 2dF QSO survey.

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach

Advanced Materials, EarlyView.
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Temperature‐Tunable Heliconical and Ferroelectric Nematics for White Lasing

Advanced Materials, EarlyView.
The discovery of the ferroelectric nematic (NF) phase in 2017 and the spontaneous symmetry‐breaking of the ferroelectric twist‐bend nematic (NTBF)phase in 2024 have made major breakthroughs in the context of self‐assembly materials. This study presents pioneering temperature and voltage‐tunable lasing in both phases, demonstrating multicolor and in ...
