Improving Photometric Redshift Estimation for Cosmology with LSST Using Bayesian Neural Networks

The Astrophysical Journal
We present results exploring the role that probabilistic deep learning models can play in cosmology from large-scale astronomical surveys through photometric redshift (photo- z ) estimation.

De‐Saturation of Single‐Atom Copper Catalysts for Accelerating Propargylic Substitution Reactions

Advanced Materials, EarlyView.
De‐saturation of copper‐based single‐atom catalysts (De‐sat SACs) are realized by a KOH‐mediated Joule thermal shock strategy. Benefiting from the under‐saturation coordination environment of single‐atom Cu center, De‐sat Cu SACs exhibit remarkable catalytic activity in propargylic substitution reactions, tolerating a broad range of nucleophiles (N–, C–

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

Advanced 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 ...

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.
