This research gives experimental dependences of mortar adhesive strength with mentioned types of masonry units on compressive strength of cement mortar. There is also the comparison of the obtained results with Russian and foreign standards in this paper....
The strength of cell-cell adhesion is a mechanical property of particular importance: it is a central variable in Steinberg's quantitative Differential Adhesion theory. It had been defined as the work of adhesion, and it was usually implied that it corresponded to the energy released upon the ...
14), and P4HS and P5HS had stronger adhesion strengths than the other homopolymers, confirming the importance of the non-canonical phenolic units. Fig. 2: Underwater adhesion of phenolic polymers with various phenol-substitution patterns. a Adhesion strengths of P(1HS-co-S) to P(5HS-co-...

Low-molecular-weight adhesives (LMWAs) possess many unique features compared to polymer adhesives. However, fabricating LMWAs with adhesion strengths higher than those of polymeric materials is a significant challenge, mainly because of the relatively we

If the adhesion strength of the tape has not been determined, report the speci?c tape used and its manufacturer. 13.4 If the test is performed after immersion, report immersion conditions and method of sample preparation. 14. Precision and Bias 8 14.1 On the basis of two interlaboratory tests...
The subtle control of the surface presentation density can provide variations in attachment strength. Not only the carbohydrate sequences but also the fact that carbohydrates can be branched while proteins cannot and that the oligosaccharide chains can be attached to the protein backbone in different ...
because of the dynamic rupture and reforming of massive hydrogen bonds23. Despite the weak strength of a single hydrogen bond, multiple hydrogen bonds within a nanocrystal cooperatively sustain a maximal pull-out force of 6 nN (Fig.4d, PVA–PVA), slightly higher than the force to fracture ...
Alongside deficits in cell adhesion, we also observed dysfunctional migration and chemotaxis in PLCγ2 Ko iPSC-macrophages. Cell-substrate adhesions affect migration speed, with low or high adhesive strength slowing down migration, while intermediate adhesive strength enables optimal migration47. It is ...
