“…19 20 One route to achieve higher retention of tannins in chemical formulations is to combine them with binding compounds 17,18 or nanoparticles to complexes 19 that can act as bridging or crosslinking agents between the matrix and tannin. Immobilization of tannin, or specific hydrolysable tannin compounds such as tannic acid, onto material surfaces has also been achieved using for instance mesoporous silicate 20 , silica microspheres 21 , collagen 22 , graphene 23 and activated carbon 24 . As reported by Xu et al (2017), dialdehyde nanocellulose can be used to covalently 26 immobilize tannin molecules.…”

In sustainable forestry, forests should produce multiple ecosystem services for society, such as timber, carbon sequestration and biodiversity. Therefore, in the evaluation of forest management strategies, we have to consider the impacts of management on several ecosystem services. In this study, we compared the effects of five different forest management strategies on timber drain, carbon stocks, carbon balance and biodiversity indicators, while maximizing economic revenues from timber production. The assessment was carried out in a boreal landscape of 43 000 ha over a 100-year calculation period. The five management strategies were rotation forest management (with thinning from below or above), continuous cover forestry, a combination of rotation forest management and continuous cover forestry and any-aged forestry. Rotation forest management with thinning from below was less profitable than the other strategies, which were close to each other in economic profitability. Rotation forest management with thinning from below was also the poorest in terms of carbon stocks, carbon balance and biodiversity indicators. Any-aged and continuous cover forestry were the best in terms of carbon sequestration and biodiversity indicators. In general, management strategies that used thinning from above and that were not restricted to rotation forest management as the only option provided more ecosystem services and were also economically profitable. Such management strategies may help to satisfy the increasing demand for diverse uses of forests.

13Persimmon proanthocyanidin (PA) biosynthetic had been reported to be 14 regulated by several transcription factors, but the miRNAs function involved in this 15 process was poorly understood. We identified a miRNA858b that putatively targeted 16 two R2R3-MYB transcription factors, DkMYB19/DkMYB20. Transcript accumulation 17 of DkMYB19/DkMYB20 and miRNA858b showed contrasting divergent expression 18 patterns during fruit development. DkMYB19/DkMYB20 were confirmed to be 19 localized in the nucleus. The interaction between miRNA858b and 20 DkMYB19/DkMYB20 were experimentally validated by 5' RNA ligase-mediated 21 RACE and LUC enzyme activity detection. Overexpression of miRNA858b led to the 22 33 Keywords 34 Persimmon 35 Proanthocyanidin 36 microRNA 37 MYB 38 39 157 provided evidence to that miRNA858b-MYB played an important role in the 158 regulation of PA biosynthesis in persimmon.159

“…Specifically, the magnetic core allows selective capture and recycling of magnetic carriers [ 84 ], while the ceramic layer provides a protective effect along with modifiable active sites [ 85 ]. For instance, the sorption capacity of Fe 3 O 4 @SiO 2 microspheres towards Au 3+ and Pd 2+ ions was significantly enhanced by the immobilization of persimmon tannin (PT) onto the surface of silica (Fe 3 O 4 @SiO 2 @PT) [ 80 ]. The complex multiphase system comprised a Fe 3 O 4 core, coated with a nanolayer of SiO 2 and an external PT shell.…”

Tannin-Based Hybrid Materials and Their Applications: A Review

et al. 2020

View full text Add to dashboard Cite

Tannins are eco-friendly, bio-sourced, natural, and highly reactive polyphenols. In the past decades, the understanding of their versatile properties has grown substantially alongside a continuously broadening of the tannins’ application scope. In particular, recently, tannins have been increasingly investigated for their interaction with other species in order to obtain tannin-based hybrid systems that feature advanced and/or novel properties. Furthermore, in virtue of the tannins’ chemistry and their high reactivity, they either physicochemically or physically interact with a wide variety of different compounds, including metals and ceramics, as well as a number of organic species. Such hybrid or hybrid-like systems allow the preparation of various advanced nanomaterials, featuring improved performances compared to the current ones. Consequently, these diverse-shaped materials have potential use in wastewater treatment or catalysis, as well as in some novel fields such as UV-shielding, functional food packaging, and biomedicine. Since these kinds of tannin-based hybrids represent an emerging field, thus far no comprehensive overview concerning their potential as functional chemical building blocks is available. Hence, this review aims to provide a structured summary of the current state of research regarding tannin-based hybrids, detailed findings on the chemical mechanisms as well as their fields of application.
