Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response

Advanced Science, EarlyView.
This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

Advanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Improving Efficiency in Facial Recognition Tasks Through a Dataset Optimization Approach

IEEE Access
It is well known that the performance of Machine Learning techniques, notably when applied to Computer Vision (CV), depends heavily on the amount and quality of the training data set. However, large data sets lead to time-consuming training loops and, in

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...
