The adhesion of soft connective tissues (tendons, ligaments, and cartilages) on bones in many animals can maintain high toughness (800Jm) over millions of cycles of mechanical loads. Such fatigue-resistant adhesion has not been achieved between synthetic hydrogels and engineering materials, but is ...
The adhesion of soft connective tissues (tendons, ligaments, and cartilages) on bones in many animals can maintain high toughness (∽800 J m−2) over millions of cycles of mechanical loads. Such fatigue-resistant adhesion has not been achieved between synthetic hydrogels and engineering mate...
The principle requires that (i) the matrix should be much softer than the fibers, (ii) the interface adhesion between the fibers and matrix should be strong, (iii) the matrix should be resistant to large shear deformation, and Synthesis of PAAm hydrogels Acrylamide (AAm; Sigma-Aldrich, A...
Fatigue-resistant adhesion of hydrogels Article Open access 26 February 2020 Introduction Many natural load-bearing tissues can restore their baseline mechanical properties quickly and endure many mechanical cycles (in some cases, many per day over many years), indicating remarkable mechanical stability ...
Here we achieve fatigue-resistant adhesion by using a particularly simple kind of elastic dissipaters: long-chain polymers. Each polymer chain is elastic before rupture. When a single covalent bond of the chain breaks, the elastic energy stored in the entire chain dissipates, amplifying the ...
A highly tough, fatigue-resistant, low hysteresis hybrid hydrogel with a hierarchical cross-linked structure for wearable strain sensorsHydrogels are considered to be one of the promising candidates for wearable sensors due to their ideal designability and excellent mechanical flexibility. Nevertheless, ...
Adhesive hydrogels have significantly attracted scientific interest as a promising material for next-generation adhesive applications, such as tissue engineering, wound dressing, electronic skin sensor, and drug delivery. However, the acute defects of low mechanical property, limited adhesion and poor ...
printable hydrogelstough hydrogelsAdhesives can stably hold adherent components together. However, a simple design of a high-performance printable tough adhesive (PTA) with instant fatigue-resistant adhesion on various substrates is still a significant challenge. Here, the authors report a rapid design ...
We develop soft and stretchable fatigue-resistant hydrogel optical fibers that enable optogenetic modulation of peripheral nerves in naturally behaving animals during persistent locomotion. The formation of polymeric nanocrystalline domains within the hydrogels yields fibers with low optical losses of 1.07 ...
Others reported a high number of circulating B-lymphocytes, altered NK-cells subsets also with increased expression of adhesion molecules, as compared to controls (Tirelli U, et al., 1994, Scand J Immunol 40:601-8), while another study showed reduced CD56+ NK-cells, and reduced CD4+ and ...
