Herein, we propose a facile self-assembly strategy to fabricate a biomass-derived N, S co-doping carbon electrode from lignosulfonate without any activation or template process. Taking advantage of the coordination between Fe ions and lignosulfonate, the resultant carbon exhibits a spherical structure with abundant graphitized nanosheets, leading to a high specific surface area with rational pore structure, which are beneficial to the electron/ion transport and storage. The high contents of doping N (8.47 wt%) and S (2.56 wt%) significantly boost the electrochemical performances. As a supercapacitor electrode, the carbon material displays high specific capacitance of 390 F g<sup>−1</sup>, excellent cycling stability and high energy density of 14.7 W h kg<sup>−1</sup> at a power density of 450 W kg<sup>−1</sup>.

With the high prevalence of tissue defects in this specific region, it is highly desirable to enhance tissue regeneration through the development and use of engineered biomaterials. Collagen, the major component of tissue extracellular matrix, has come into the limelight in regenerative medicine. Although collagen has been widely used as an essential component in biomaterial engineering owing to its low immunogenicity, high biocompatibility, and convenient extraction procedures, there is a limited number of reviews on this specific clinic sector. The need for mechanical enhancement and functional engineering drives intensive efforts in collagen-based biomaterials concentrating on therapeutical outcomes and clinical translation in oral and craniofacial tissue regeneration. Herein, we highlighted the status quo of the design and applications of collagen-based biomaterials in oral and craniofacial tissue reconstruction. The discussion expanded on the inspiration from the leather tanning process on modifications of collagen-based biomaterials and the prospects of multi-tissue reconstruction in this particular dynamic microenvironment.

The results of scanning electron microscopy and atomic force microscopy showed that the film based on cross-linked collagen/delphinidin catalyzed by laccase exhibited a denser layer structure and a rougher surface. The dry and wet tensile strengths of the laccase-catalyzed collagen/delphinidin film (Col/Dp-LA film) increased by 41.74 MPa and 13.13 MPa in comparison with that of the pure collagen film, respectively. Moreover, the Col/Dp-LA film presented good antioxidant and barrier properties demonstrated by the results of free radical scavenging rate, light transmission rate, and water vapor permeability. The intelligent collagen-based film was obtained by incorporating <i>Vaccinium oxycoccus</i> pigment into the Col/Dp-LA film, which could change color under different pH values. When applied to the preservation of fish fillets<i>,</i> the film could release Dp to minimize oxidative rancidity and prolong the shelf life of the fish for 2 days. Meanwhile, the film showed visual color changes from purplish-red to greyish-blue after the fish spoilage.

Especially, enzymatic unhairing based on protease has been applied to leather-making for a long time, however, it still has the key problem of slow permeation in the animal hide, resulting in slow unhairing rate, poor hair removal effect, excessive proteolysis of hide collagen, and decreased leather quality. Aiming at the key problem of bio-unhairing technology, fluorescent labeling technique and confocal laser scanning microscopy were used to investigate the protease permeation behaviors into the animal hide based on well-prepared labeled proteases, as well as the quantitative analysis of the protease amount in different hide layers. The results show that the protease mainly permeates the bovine hide through transfollicular routes from the hair side, and although the intercellular-interfibrillar pathway also exists, it does not play an important role. Additionally, the protease permeation behaviors into the hide are greatly impacted by the charge states of the hide and protease proteins, depending on the isoelectric points (pI) of the proteins and solution pH values. When the solution pH is not between the pI values of the two proteins, the similarly charged protease can quickly and deeply penetrate the hide because of the electrostatic repulsion. The established mechanism provides a theoretical basis for developing an efficient enzymatic unhairing technology for leather-making, and this can also be applied to other processes involving the enzyme permeation into the hide or leather.</p><h3>Graphical Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-023-00117-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4654713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
