Polymer‐Crosslinking System‐Filler Interactions in Polychloroprene Adhesives: Experimental and Molecular Modeling Insights

Journal of Applied Polymer Science, EarlyView.
The use of polychloroprene is common in elastomeric adhesives. This study highlights the possible substitution of zinc oxide curing systems to a less hazardous metal complex, also evaluating the changes that higher surface area fillers can bring to the adhesive.

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

Journal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Synthesis, Characterization, Biological Properties, and Sensor Applications of Novel Thiosemicarbazone Derivatives

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT In this study, novel thiosemicarbazone derivative molecules (5a–j) were synthesized. The characterization of the synthesized molecules was carried out using 1H–, 13C–NMR, FT–IR, and Q–TOF spectroscopic techniques. Then, the inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and ...

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...
