Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

open access: yesInfoMat, EarlyView.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

Utilizing Gold Nanoparticle Decoration for Enhanced UV Photodetection in CdS Thin Films Fabricated by Pulsed Laser Deposition: Exploiting Plasmon-Induced Effects

open access: yesNanomaterials
UV sensors hold significant promise for various applications in both military and civilian domains. However, achieving exceptional detectivity, responsivity, and rapid rise/decay times remains a notable challenge. In this study, we address this challenge

Rhodopsin‐mimetic adaptive photodetectors for intelligent and secure vision systems

open access: yesInfoMat, EarlyView.
Inspired by the adaptive mechanisms of biological vision, we developed a rhodopsin‐mimetic photovoltaic dual‐transistor (PVT2) photosensor that decouples charge accumulation and release by integrating a quasi‐2D perovskite photodiode with dual thin‐film transistors.

PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

open access: yesPolymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...

Looking backward to move forward: Enhancing metadata in scientific collections through interdisciplinary collaboration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Early modern herbaria house important and useful data on historic environments. However, their contents are often inhospitable to scientific use. Despite this challenge, once their contents have been deciphered, such specimens present novel research opportunities.

High detectivity terahertz radiation sensing using frequency-noise-optimized nanomechanical resonators

open access: yesAPL Photonics
We achieve high detectivity terahertz radiation sensing using a silicon nitride nanomechanical resonator functionalized with a metasurface absorber. High performances are achieved by striking a balance between the frequency stability of the resonator and

Persuasion in the political marketplace: How firms snitch on rivals to encourage regulatory enforcement

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary We study an important, but largely overlooked, non‐market strategy used by firms in the enforcement stage of policy: “snitching,” that is, providing intelligence about potential violations of their rivals in an attempt to persuade regulators to fine them.

Structure‐Controlled Cyclopentadithiophene Derived Non‐Fullerene Acceptors for Efficient Near‐Infrared Organic Photodetectors

open access: yesSmall, EarlyView.
This work demonstrates high‐performance solution‐processed NIR OPDs using DTP‐ and DTTP‐based NFAs (OC and SC), where donor‐core engineering enables tunable absorption and balanced optoelectronic properties; notably, DTP‐based devices achieve broad NIR response, low dark current, and high detectivity, highlighting their potential for advanced NIR ...

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

open access: yesX-Ray Spectrometry, EarlyView.
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.
