“…When water molecules enter the bonding interface and form a water film, the direct contact between the adhesive and the substrate is severely restricted [ 87 ], resulting in a decrease in the surface energy of the adhesive, which in turn leads to a gap between the adhesive and the substrate. The bonding strength is significantly reduced or cannot be bonded at all [ 88 , 89 ].…”

Hydrogel is a polymer matrix containing a large amount of water. It is similar to extracellular matrix components. It comes into contact with blood, body fluids, and human tissues without affecting the metabolism of organisms. It can be applied to bone and cartilage tissues. This article introduces the high-strength polymer hydrogel and its modification methods to adapt to the field of bone and cartilage tissue engineering. From the perspective of the mechanical properties of hydrogels, the mechanical strength of hydrogels has experienced from the weak-strength traditional hydrogels to the high-strength hydrogels, then the injectable hydrogels were invented and realized the purpose of good fluidity before the use of hydrogels and high strength in the later period. In addition, specific methods to give special physical properties to the hydrogel used in the field of bone and cartilage tissue engineering will also be discussed, such as 3D printing, integrated repair of bone and cartilage tissue, bone vascularization, and osteogenesis hydrogels that regulate cell growth, antibacterial properties, and repeatable viscosity in humid environments. Finally, we explain the main reasons and contradictions in current applications, look forward to the research prospects in the field of bone and cartilage tissue engineering, and emphasize the importance of conducting research in this field to promote medical progress.

“…The large studies were researched about the design of the electrochemical sensors for identification micro RNAs 23,24 . The design of appropriate beds is important to provide a good response in the electrochemical reactions due to the low amount of miRs in the body fluids 25 . P19 protein is an important nanobiotechnology tool that increases the sensitivity of miR detection in the electrochemical sensors 26,27 .In the recent research, this protein is bound to the electrode via a linker on the electrode, so the probability of connection with the duplexes of RNA/miR is being challenged in every step 28,29 .…”

electrochemical sensors are the tools to detect the accurate and sensitive miRs. there is the challenge to increase the power and sensitivity of the surface for the electrochemical sensor. We design a viruslike hallow structure of cuco 2 o 4 that it holds the large amounts of p19 protein by mimicking of inherent virus (Carnation italian ringspot virus) to detect 21mir with the limit of detection (LOD = 1aM). The electrochemical measurements are performed between the potentials at −0.3 V and +0.3 V with 1 mM [fe(cn) 6 ] −3/−4. After dropping the cuco 2 o 4 on the Scpe (screen carbon printed electrode), the sensor is turned on due to the high electrochemical properties. Then, p19 proteins move into the hallow structure and inhibit the exchange of electrochemical reactions between the shells and the sensor is turned off. Then, adding the duplexes of RNA/miRs cause to increase the electrochemical property of p19 due to the change of p19 conformation and the system is turned on, again. So, for the first time, a virus-like hallow structure has been used to detect the 21miR in the human serum, MCF-7, Hella cells, with high sensitivity, specificity, and reproducibility in few minutes.

“…Thus, for this molecular interaction to happen, there must be intimate contact between the polymer (in this case the organic coating) and the oxide. However, intimate contact is not enough for adhesion to take place and molecular interactions involving both physical and chemical bonding must occur [89]. Van der Waals forces-in particular London, Keesom, and Deebye interactions-are responsible for physical bonding [89].…”

“…When good adhesion between the organic coating and the oxide occurs, water, and/or aggressive ions cannot easily ingress the interface and propagate along it and, consequently, corrosion is restrained [93,97,99]. All in all, the stability of the chemical and physical interfacial bonding, as well as the number of interactions at the interface, play a critical role in environmental-assisted delamination process [89,98,100].…”

A Review on Anodizing of Aerospace Aluminum Alloys for Corrosion Protection

et al. 2020

Aluminum alloys used for aerospace applications provide good strength to weight ratio at a reasonable cost but exhibit only limited corrosion resistance. Therefore, a durable and effective corrosion protection system is required to fulfil structural integrity. Typically, an aerospace corrosion protection system consists of a multi-layered scheme employing an anodic oxide with good barrier properties and a porous surface, a corrosion inhibited organic primer, and an organic topcoat. The present review covers published research on the anodic oxide protection layer principles and requirements for aerospace application, the effect of the anodizing process parameters, as well as the importance of process steps taking place before and after anodizing. Moreover, the challenges of chromic acid anodizing (CAA) substitution are discussed and tartaric-sulfuric acid anodizing (TSA) is especially highlighted among the environmentally friendly alternatives.
