Dual‐Polarization‐Sensitive Organic Photodetectors for Real‐Time Polarimetric Imaging
Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.Bias‐switchable organic photodetectors with orthogonally stacked uniaxially oriented polymer layers enable dual‐polarization detection and real‐time polarimetric imaging. This scalable, template‐free strategy achieves a high dichroic ratio (>11), rapid response (>500 Hz), and detectivity up to 1013 Jones.

The effects of molecular structure on the electrical conductivity of polymers [PDF]
The role of Quantum Theoretical Methods is both predictive and supportive of experimental results in Chemistry. Present day methods are able to calculate vibrational spectra and stereochemical interactions for molecules of moderate size (up to 20 atoms).

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT The migration of intentionally and non‐intentionally added substances (IAS/NIAS) from food packaging into foodstuffs presents a significant challenge to consumer health and food safety. Accurate and comprehensive identification of these chemical migrants is therefore paramount.

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

ChemSusChem, Volume 19, Issue 8, 28 April 2026.This prospective life cycle analysis evaluates perovskite–silicon (PSC–Si) tandem solar cells (TSCs), assessing environmental impacts from their material extraction to end‐of‐life. We compare the environmental impact of four TSC designs with that of silicon PV, highlighting hotspots in tandem architecture, and explore strategies to reduce environmental

Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle
Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.
