On‐Chip Colloidal Quantum Dot Photodetectors With a Complementary Metal–Oxide–Semiconductor‐Compatible Architecture for Near‐Infrared Light Sensing and Electrical Signal Amplification

open access: yesAdvanced Photonics Research, Volume 7, Issue 11, November 2026.
A CMOS‐compatible near‐infrared photodetector integrates a PbS colloidal quantum dot photodiode with a silicon bipolar junction transistor for on‐chip optical sensing and electrical signal amplification. The photovoltage generated by the photodiode directly drives the transistor, enabling a current gain of approximately 11.4 without external ...

Millisecond Flash Photonic Regeneration of Conductive Copper From CuO Thin Films

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 6, November 2026.
Millisecond flash photonic heating regenerates conductive copper from fully oxidized CuO thin films. Pulse trains partially reduce dense, ≈50 nm pulsed‐laser‐deposited CuO into a laterally heterogeneous Cu/Cu2O/CuO composite spanning the film, tuned by repetition number alone.

Quantifying photon counting detector (PCD) performance using PCD‐CT images. Part II. detector spectral response function of clinical scanners

open access: yesMedical Physics, Volume 53, Issue 11, November 2026.
Abstract Background An earlier publication, Med. Phys. 52:2796 (2025), reported a method for estimating the mean output counts of photon‐counting detectors (PCDs) from reconstructed PCD‐CT images. This capability provides a foundation for end users of clinical PCD‐CT systems to characterize PCD performance without access to raw data.

Two‐Dimensional Hydrazopyridinium Lead Iodide Perovskite Photodetectors With Broadband Sensitivity and Photoconductive Gain

open access: yesSmall Science, Volume 6, Issue 11, November 2026.
Hydrazopyridinium lead iodide combines near‐linear Pb─I─Pb bonding with a 2.13 eV bandgap in a two‐dimensional Dion–Jacobson perovskite. Spacer‐controlled crystal engineering enables broadband UV‐to‐visible photodetection with enhanced deep‐UV sensitivity.

Forensic Analysis of Fountain Pen Calligraphy–II. Real Evidence Analysis at the Public Prosecutor's Office

open access: yesX-Ray Spectrometry, Volume 55, Issue 6, Page 858-867, November/December 2026.
ABSTRACT The present study is a report of the real forensic analysis of characters written by fountain pen(s) on two sheets of paper. One sheet is the calligraphy written by the victim of the Sayama incident. The other is number characters written with a fountain pen found on the lintel of the suspect's house.
