The effect of coffee thermocycling and color correction serum on the colorimetric properties and hardness of CAD‐CAM restorative materials

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To compare the stainability, translucency, opalescence, whiteness, gloss, and hardness of 4 computer‐aided design and computer‐aided manufacturing (CAD‐CAM) restorative materials after simulated coffee drinking and color correction. Materials and Methods Four CAD‐CAM blocks were investigated (n = 40): resin nanoceramic (Cerasmart, CS),

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

open access: yesJournal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

A review of xenobiotic membrane transporter expression within the human placenta: Lessons gained from primary tissue and in vitro methodologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A summary of the current knowledge around membrane transporter expression in the most widely used in vitro models of human trophoblasts, including primary placental tissue, cancer cell lines and trophoblast stem cells, as well as the techniques to attempt to mimic the human placenta in vivo.

Predictive Model for Epoxy‐Amine Polymerizations at Decreased Tc Using Variable Frequency Microwaves

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Two‐way interaction of basicity and entropy. ABSTRACT This study presents a predictive model for the thermo‐mechanical properties of epoxy polymers cured with Variable Frequency Microwave (VFM) processing. The model is based on properties derived from the structural features of the epoxide and amine precursors.

Analysis of the Degradation of Thermochromic Sensors in Electrical Devices

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
This study examines the degradation of microencapsulated leuco thermochromic pigments, both pure and embedded in epoxy, under thermal, cyclic, and QUV aging. UV radiation is the main factor causing irreversible loss of thermochromism due to microcapsule damage and solvent loss, while thermal exposure produces minor effects.
