Bioactive Dental Adhesive System With tt-Farnesol: Effects on Dental Biofilm and Bonding Properties

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
BackgroundComposite dental restorations are commonly used to restore cavitated carious lesions. Unfortunately, the main reason for failure is the development of secondary caries adjacent to the restoration.

Effect of crosslinking agent on the two component acrylic structural adhesive based on methyl methacrylate [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2022
Hypothesis; Acrylic adhesives based on methyl methacrylate are thermoplastic polymers due to their linear polymerization. By adding two or more functional acrylate or methacrylate monomers it is expected that cross-linking may occur partially in leading ...

Nanoporous monolithic microsphere arrays have anti-adhesive properties independent of humidity [PDF]

open access: yesMaterials 2016, 9, 373, 2016
Bioinspired artificial surfaces with tailored adhesive properties have attracted significant interest. While fibrillar adhesive pads mimicking gecko feet are optimized for strong reversible adhesion, monolithic microsphere arrays mimicking the slippery zone of the pitchers of carnivorous plants of the genus Nepenthes show anti-adhesive properties even ...

On/off switching of adhesion in gecko-inspired adhesives [PDF]

open access: yes, 2020
In this study, the adhesion-detachment behaviour of a gecko-inspired adhesive pad was investigated to understand the on/off switching mechanisms of adhesion in gecko feet. A macroscopic spatula model was fabricated using silicone rubber, and adhesion tests combining lateral sliding and vertical debonding were conducted. It was observed that the contact

Elasticity solution of adhesive tubular joints in laminated composites with axial symmetry [PDF]

open access: yesArchive of Mechanical Engineering, 2018
This paper presents an elasticity solution of adhesive tubular joints in laminated composites, with axial symmetry. In this model, adherends are orthotropic shells and the stacking sequences can be either symmetric or asymmetric.
