Synthesizer: Chemistry‐Aware Machine Learning for Precision Control of Nanocrystal Growth

open access: yesAdvanced Materials, EarlyView.
A new, data‐efficient approach to CsPbBr3 nanocrystal optimization combines chemical and physical insights with a Gaussian Process‐based machine learning algorithm. Implementation of the “Synthesizer” enables nm‐precise tuning of the emission wavelength while reducing experimental load in optimizing peak narrowness and photoluminescence quantum yield ...

On the Feasibility of Deriving Pseudo-redshifts of Gamma-Ray Bursts from Two Phenomenological Correlations

open access: yesThe Astrophysical Journal
Accurate knowledge of gamma-ray burst (GRB) redshifts is essential for studying their intrinsic properties and exploring their potential applications in cosmology. Currently, only a small fraction of GRBs have independent redshift measurements, primarily

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

open access: yesAdvanced 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.

2dF QSO Redshift Survey

open access: yes, 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.

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

open access: yesAdvanced 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.

Photometric Redshift Estimation of Quasars by a Cross-modal Contrast Learning Method

open access: yesThe Astronomical Journal
Estimating photometric redshifts (photo- z ) of quasars is crucial for measuring cosmic distances and monitoring cosmic evolution. While numerous point estimation methods have successfully determined photo- z , they often struggle with the inherently ill-

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

open access: yesAdvanced 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 ...
