Identification of High-redshift Galaxy Overdensities in GOODS-N and GOODS-S

The Astrophysical Journal
We conduct a systematic search for high-redshift galaxy overdensities at 4.9 < z _spec < 8.9 in both the Great Observatories Origins Deep Survey (GOODS)-N and GOODS-S fields using James Webb Space Telescope/Near-Infrared Camera (JWST/NIRCam) imaging from

Micro‐Strain Responsive Near‐Infrared Mechanoluminescence for Potential Nondestructive Artificial Joint Stress Imaging

Advanced Materials, EarlyView.
In situ and real‐time stress sensing during total knee replacement procedure is expected to be realized based on near‐infrared mechanoluminescent phosphor of Sr3Sn1.98Sb0.02O6.99, which has the lowest strain sensitivity as low as 50 µst. Abstract Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the ...

Li‐Well ZnO Memtransistors: High Reliability for Neuromorphic Applications

Advanced Materials, EarlyView.
A novel lithium (Li)‐well ZnO memtransistor integrates transistor switching and nonvolatile memory, akin to ferroelectric field‐effect transistors (FeFETs) and floating gates, while enabling low‐power operation via Li⁺ ion migration. Li⁺ ion migration and switching mechanisms were confirmed by 3D secondary ion mass spectrometry (SIMS).

Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

Advanced Materials, EarlyView.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.

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 ...
