“…It is mainly composed of proteins, particularly fibroin [ 54 ], a β-keratin similar to those present in the human body. Fibroin is composed of β-sheets in a (Gly-Ser-Gly-Ala-Gly-Ala) n sequence; amino acids confer a general isoelectric point around 1.4–2.8 pH values [ 55 , 56 , 57 ].…”

In just a few years, chemists have significantly changed their approach to the synthesis of organic molecules in the laboratory and industry. Researchers are encouraged to approach “greener” reagents, solvents, and methodologies, to go hand in hand with the world’s environmental matter, such as water, soil, and air pollution. The employment of plant and animal derivates that are commonly regarded as “waste material” has paved the way for the development of new green strategies. In this review, the most important innovations in this field have been highlighted, paying due attention to those materials that have played a crucial role in organic reactions: wool, silk, and feather. Moreover, we decided to focus on the other most important supports and catalysts in green syntheses, such as proteins and their derivates. Different materials have shown prominent activity in the adsorption of metals and organic dyes, which has constituted a relevant scope in the last two decades. We intend to furnish a complete screening of the application given to these materials and contribute to their potential future utilization.

With their excellent properties, hydrogels have attracted much attention for their potential application. However, it is still necessary to study the influencing factors of the hydrogel preparation process and its self‐healing mechanism. In this paper, the preparation method of boric acid (BA) cross‐linked poly(vinyl alcohol) (PVA)/hyaluronic acid (HA) hydrogel appeared to become studied in order to explore the effect of pressure in the cross‐linking process. Associated with, PVA and HA were combined, and then the mixture was cross‐linked with BA to produce BA‐PVA/HA hydrogel. The state of the hydrogel after cross‐linking was transformed after centrifugal pressure method, and its performance was analyzed experimentally. Compared with the BA‐PVA/HA hydrogel without centrifugal supercharging, the hydrogel after centrifugation has lower water content and lubricating effect, and the surface hardness is improved at the same time. In addition, the BA‐PVA/HA hydrogel has no external stimulation at room temperature, can also self‐heal quickly have based on hydrogen bonds, and has good recyclability. These results indicate that adding centrifugation steps in the preparation of BA‐PVA/HA hydrogels could properly switch the state of the hydrogels, which is expected to provide a certain research basis for the preparation and application of hydrogels.

One of the most common problems encountered by patients using artificial joints is the high wear rate. In this study, a polyvinyl alcohol/polyethylene glycol (PVA/PEG) gel was prepared through the cross-linking reaction between polyvinyl alcohol (PVA) and polyethylene glycol (PEG) solutions. This gel can lubricate artificial joints, thereby lowering their coefficient of friction (COF) and increasing their service life. Various techniques, such as Fourier transform infrared spectroscopy, X-ray diffraction, Raman spectra, X-ray photon spectroscopy, and thermogravimetric analyses, were used to analyze the structure of this synthetic gel. The tribological results indicated that the synthetic gel’s lubrication effect was the most optimum when it contained PVA (10 wt%) and PEG (15 wt%). An average COF of 0.05 was obtained under a load of 10 N and at a speed of 1.0 cm/s. In addition, the wear rate was reduced in comparison to distilled water. Furthermore, the biological tests proved that the PVA/PEG gel was highly biocompatible. Thus, this study introduces a novel technique to prepare PVA/PEG gels that improve the tribological performance of artificial joints.
