Remineralizing effect of commercial fluoride varnishes on artificial enamel lesions

Brazilian Oral Research
: The aim of this study was to evaluate soluble and insoluble fluoride concentrations in commercial varnishes, and their remineralization effect on artificial caries enamel lesions using surface and cross-sectional microhardness evaluations. Forty bovine

Fouling in Emulsion Polymerization: Fundamentals and Methods of Investigation

Journal of Applied Polymer Science, EarlyView.
ABSTRACT The current understanding of fouling in emulsion polymerization is summarized from an engineering perspective and from a physical‐chemistry perspective. Emulsion polymerization in semibatch mode offers better control over the number of particles and side reactions than batch mode. Both reaction fouling and particulate fouling are observed, the

Complex Material Analysis of Reverse Painting on Glass by Means of Photography, Microscopy, and Spectroscopic Techniques

Chemistry–Methods, EarlyView.
The material research of reverse paintings on glass combines infrared spectroscopy and liquid chromatography–mass spectroscopy to investigate the binders. Observation methods (macro‐ and microphotography) and the scanning electron microscopy with energy‐dispersive spectrometer are used for research of metal composition. Reverse paintings on glass are a

From Green to Brown: Characterization of the Fast Alteration of Modern Greenish Enamels in Glass Windows

ChemPlusChem, EarlyView.
Spots and stains appeared on the modern green enamel from different stained‐glass windows as a consequence of environmental alteration. The multianalytical characterization showed a 3‐step alteration mechanism divided into Pb2+ lixiviation from the enamel, formation of hydrocerussite (2PbCO3·Pb(OH)2), and transformation into scrutinyite (α‐PbO2) and ...

Evaluation of lead levels in decorative and automobile paints marketed in South–West, Nigeria

Discover Environment
Paints and coatings add aesthetics to our daily lives. Their demand has increased due to urbanization and has led to an increase in lead (Pb) in the ecosystem and its potential risks to health. Pb is toxic and has no safe levels for children.

Analysis of PM2.5 Morphology, Composition and Health Risk in a Multi‐Chair Dental Clinic

Environmental Toxicology, EarlyView.
ABSTRACT Particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) at high concentrations in dental clinics poses significant health risks to healthcare professionals. However, the morphology and chemical composition of PM2.5 in specific environments are not yet fully elucidated.
