Characterization on the Copolymerization Resin between Bayberry (Myrica rubra) Tannin and Pre-Polymers of Conventional Urea–Formaldehyde Resin

, 2022
By focusing on the disadvantages of weak water resistance and high formaldehyde emission of urea–formaldehyde resin (UF), this research provides a new method to overcome these shortages of UF resin by using tannin for partial substitution of urea ...

Graphene oxide–modified fluoridated varnish promotes mineral recovery in demineralized bovine enamel: An in vitro study

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the efficacy of an experimental fluoridated varnish modified with graphene oxide (GO) nanoparticles in arresting initial caries lesion progression and promoting mineral recovery in demineralized bovine enamel.

Prevention and Management of Tooth Discolouration of Endodontic Origin (DEO): A State‐of‐the‐Art Review

International Endodontic Journal, EarlyView.
ABSTRACT Background Tooth discolouration of endodontic origin (DEO) refers to an undesirable change in tooth colour arising from the pulp space as a result of reactive physiological processes, pathological processes or endodontic procedures and materials. As DEO frequently affects teeth in the aesthetic zone, it may substantially impair self‐esteem and

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Characterization of the Low Molar Ratio Urea–Formaldehyde Resin with 13C NMR and ESI–MS: Negative Effects of the Post-Added Urea on the Urea–Formaldehyde Polymers

, 2018
The structural changes during three-step synthesis of low-molar ratio urea–formaldehyde (UF) resin were tracked by quantitative 13C nuclear magnetic resonance (13C NMR) analysis and electrospray ionization-mass spectrometry (ESI–MS ...

Integration of Chemical Probes and Degradomics Reveals That Cathepsin B Functions Primarily as a Dipeptidyl Carboxypeptidase in Macrophages

ChemMedChem, Volume 21, Issue 21, 12 November 2026.
An integrated chemical biology and degradomics approach reveals the proteolytic landscape of cathepsin B in mouse macrophages. Z‐RK‐AOMK perturbs the cysteine cathepsin network and reveals that cathepsin B predominantly exhibits dipeptidyl carboxypeptidase activity in cells.

Influence of glyoxal on curing of urea-formaldehyde resins

, 2022
S.1-6In the present paper, the effect of glyoxal on the gel formation within the adhesive systems based on urea-formaldehyde (UF) resins is shown. A reduction of formaldehyde content in wood-based panels by decreasing the formaldehyde/urea molar ratio in
