Decoupling Photophysical Brightness and Cellular Imaging Efficiency in 4‐ANI‐Based Fluorophores: The Critical Role of Sterically Hindered N‐Substituents

open access: yesChemBioChem, Volume 27, Issue 19, 14 October 2026.
A screening of twenty‐one 4‐ANI fluorophores led to the identification of an N‐cycloheptylamine derivative with >10‐fold enhanced cellular fluorescence, enabling submicromolar imaging with minimal cell perturbation. Integrated photophysics, microscopy, flow cytometry, and DFT reveal that sterically hindered N‐substituents optimize uptake and solubility.

Phthalic acid esters (PAEs) in the food chain

open access: yesCzech Journal of Food Sciences, 2006
Phthalic acid esters (PAEs) rank among the primary risk pollutants and their adverse effects may endanger the environmental balance and affect the ontogenetic development of live organisms and their body functions. Therefore, the aim of this study was to

Photodegradation of Azo and Hydrazone Colourants on Cellulose‐Based Materials: A Mass Spectrometric Screening

open access: yesChemistrySelect, Volume 11, Issue 37, 6 October 2026.
Natural‐light ageing of early azo dyes and hydrazone pigments (AY36, AO7, and AR1) on cellulose‐based supports produces marked chromatic changes and distinct molecular transformations. LC–HRMS analysis of aged AY36 reveals degradation products associated with N‐oxidation, N‐dearylation, azo‐bond oxidation, and formaldehyde addition, providing a first ...

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Temperature-Dependent Reactions of Phthalic Acid on Ag(100) [PDF]

open access: yes, 2015
We have investigated the adsorption and temperature-dependent reactions of phthalic acid on Ag(100), in the temperature range 110-700 K, by synchrotron radiation X-ray photoelectron spectrocopy (SR-XPS), temperature-programmed desorption (TPD) and near ...

Urinary phthalate exposures and risk of breast cancer: the Multiethnic Cohort study

open access: yesBreast Cancer Research, 2021
Background The epidemiologic evidence from observational studies on breast cancer risk and phthalates, endocrine disrupting chemicals, has been inconsistent. In the only previous study based on pre-diagnostic urinary phthalates and risk of breast cancer,
