Multiscale Modeling Approach of Slot Die Coating of Unidirectional Glass Fiber Fabric

Journal of Applied Polymer Science, EarlyView.
2D macroscale and microscale computational fluid dynamic (CFD) models are combined in a multiscale approach to develop a model for slot die coating of glass fiber (GF) fabrics in cellulose nanocrystal (CNC) dispersion as a sizing. For slot die coating models with and without vacuum assist, the model is able to predict stable operating parameters which ...

Fabrication of Polypropylene/CNF Composite Foam by Foam Extrusion With Chemical Blowing Agent

Journal of Applied Polymer Science, EarlyView.
Polypropylene/CNF composite foams were fabricated by a foam extrusion process using a chemical foaming method. The addition of CNFs resulted in finer and higher‐density cell structures, even at low chemical blowing agent concentrations. Furthermore, X‐ray CT and SEM observations revealed a unique spike‐like cell structure generated by the penetration ...

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

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 ...
