Hexosamine content of marine biological adhesives
Microchemical Journal, 1972Abstract Mytilus edulis byssal threads have been shown to contain both glucosamine and galactosamine. Inadvertent degradation of the material probably is the reason for the reported absence of these hexosamines from the Mytilus adhesive; evidence for this explanation has been found.

Denture adhesives: Cytotoxicity, microbial contamination, and formaldehyde content
The Journal of Prosthetic Dentistry, 1993Denture adhesives are extensively used to enhance retention of dentures. Denture adhesives and their leachable components are ingested, but reports on the biologic aspects of denture adhesives are scarce. This study investigated some biological properties of 19 commercially available denture adhesives.

Content and solubility of sodium in denture adhesives
The Journal of Prosthetic Dentistry, 1991The objectives of this study were to determine the content and solubility of sodium in denture adhesives, and to ascertain relationships between these values. Nine powder and 10 cream denture adhesives were assayed for sodium by spectrophotometry. The range of dry weight sodium content was 2.4 gm/100 gm to 6 gm/100 gm. The range of solubility of sodium

International Journal of Adhesion and Adhesives, 2005
Abstract Different amounts of a polyisocyanate (3–5 wt%) were added to a polychloroprene (PCP) adhesive to determine their influence on the adhesion properties of an ethylene vinyl acetate copolymer containing 12 wt% vinyl acetate (EVA12). EVA12 was treated with sulphuric acid to increase its adhesion, and improved wettability, creation of carbon ...

Reduction of solvent content in toluene–neoprene adhesives and in acetone–polyurethane adhesives
Journal of Adhesion Science and Technology, 2001The desorption of toluene in a polychloroprene (neoprene)-toluene adhesive and in a commercial neoprene adhesive was studied in air at three different temperatures by monitoring the weight loss vs time. Similarly, the desorption of acetone in a polyurethane adhesive and in a commercial adhesive was also considered.

ACS Sustainable Chemistry & Engineering, 2020
Formaldehyde-free, water-resistant, and environmentally friendly wood adhesives were prepared from starches via a simple one-step epoxidation reaction followed by cross-linking using diethylenetriamine. This study focused on the effect of amylose/amylopectin ratio of starch (high amylose, low amylose, and amylopectin) on the epoxidation reaction and on

Dust Content and Adhesion Characteristics of Five Corn Samples
Transactions of the ASABE, 2020HighlightsThe corn sample and centrifuge speed interactions were statistically significant predictors of dust generation.Attachment strengths of dust particles were calculated, with forces ranging from less than 4.6 × 10-10 N to 2.1 × 10-8 N.A sequential centrifuge experiment indicated a bimodal distribution of adhesion forces.Abstract.

Urea–resorcinol–formaldehyde adhesives of low resorcinol content
Journal of Applied Polymer Science, 1993AbstractLow resorcinol content cold‐setting urea–resorcinol–formaldehyde (URF) resins were prepared. Most of these adhesives had water‐resistant properties, whereas some also presented weather‐ and boil‐proof adhesive characteristics and performance. URF resins of acceptable adhesive performance were also prepared by inducing branching by introducing a

Senescent cells deposit intracellular contents through adhesion-dependent fragmentation
2023ABSTRACTCellular senescence is a complex cell state with roles in tumor suppression, embryonic development and wound repair. However, when misregulated, senescence contributes to aging and disease. Here we identify that senescent cells generate/break off large membranebound fragments of themselves through cell-to-cell adhesion.

Hot-Melt Pressure-Sensitive Adhesives Containing High Biomass Contents
Industrial & Engineering Chemistry Research, 2014A hot-melt pressure-sensitive adhesive (PSA) was generated containing a high content of renewable biomass. The polymer is based on a commercial hot-melt acrylic formulation containing primarily 2-ethylhexyl acrylate (EHA). The new polymer is synthesized with a majority of the EHA replaced with a macromonomer (MM) prepared with l-lactide and e ...
