Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

open access: yesAdvanced Functional Materials, Volume 36, Issue 28, 7 April 2026.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 7, 7 April 2026.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.

A Stepwise [4 + 3] Cycloaddition Reaction of the 1,3-Diphenyl-2-azaallyl Anion [PDF]

open access: yes, 1993
The 1,3-diphenyl-2-azaallyl anion (1) undergoes [3 + 2] cycloaddition reactions with the s-cis-fixed 1,3-dienes 8-11. In contrast, 1,1,2,2,3,3-hexamethyl-4,5-bis(methylene)cyclopentane (7) reacts with 1 to give the [4 + 3] cycloadduct 13 and the linear 1,

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis

open access: yesChemPhotoChem, Volume 10, Issue 4, April 2026.
This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.

Synthesis, Biodistribution and In vitro Evaluation of Brain Permeable High Affinity Type 2 Cannabinoid Receptor Agonists [11C]MA2 and [18F]MA3 [PDF]

open access: yes, 2016
The type 2 cannabinoid receptor (CB2) is a member of the endocannabinoid system and is known for its important role in (neuro)inflammation. A PET-imaging agent that allows in vivo visualization of CB2 expression may thus allow quantification of ...

Synthesis, Characterization, and Biological Evaluation of Aliphatic‐Substituted Benzimidazole Derivatives: Induction of Apoptosis, Cell Cycle Arrest, and Molecular Docking in Breast Cancer Cells

open access: yesDrug Development Research, Volume 87, Issue 2, April 2026.
ABSTRACT A new series of aliphatic‐substituted benzimidazole derivatives was synthesized and structurally characterized to evaluate their potential anticancer activity. Among the synthesized compounds, compound 4 exhibited the most potent cytotoxic effects against MCF‐7 and MDA‐MB‐231 breast cancer cell lines, with IC₅₀ values comparable to those of ...

2-Methylsulfanylbenzo[f]isoquinoline [PDF]

open access: yes, 2015
S-Methylation of a 4-(naphth-2-yl)-β-thiolactam gives an intermediate 4-(naphth-2-yl) substituted 1-azetine which undergoes a [2+2] ring-opening followed by electrocyclic ring closure of the resulting 2-azadiene to give a benzo[f ...
