| 1 | Construction of interfacial dynamic bonds for high performance lignin/polymer biocomposites显示文摘Lignin is the largest natural aromatic biopolymer,but usually treated as industrial biomass waste.The development of lignin/polymer biocomposites can promote the high value utilization of lignin and the greening of polymers.However,the weak interfacial interaction between industrial lignin and polymer induces poor compatibility and serious agglomeration in polymer owing to the strong intermolecular force of lignin.As such,it is extremely difficult to prepare high performance lignin/polymer biocomposites.Recently,we proposed the strategy of in situ construction of interfacial dynamic bonds in lignin/polymer composites.By taking advantage of the abundant oxygen-containing polar groups of lignin,we inserted dynamic bonding connection such as hydrogen bonds and coordination bonds into the interphase between lignin and the polymer matrix to improve the interfacial interactions.Meanwhile,the natural amphiphilic structure characteristics of lignin were utilized to construct the hierarchical nanophase separation structure in lignin/polymer composites.The persistent problems of poor dispersity and interfacial compatibility of lignin in the polymer matrix were effectively solved.The lignin-modified polymer composites achieved simultaneously enhanced strength and toughness.This concise review systematically summarized the recent research progress of our group toward building high-performance lignin/polymer biocomposites through the design of interfacial dynamic bonds(hydrogen bonds,coordination bonds,and dynamic covalent bonds)between lignin and different polymer systems(polar plastics,rubber,polyurethane,hydrogels,and other polymers).Finally,the future development direction,main challenges,and potential solutions of lignin application in polymers were presented. | Jianbin Mo Haixu Wang Mengzhen Yan Jianhua Huang Rui Li Danting Sun Junjie Lei Xueqing Qiu Weifeng Liu | 2023 | Frontiers of Chemical Science and Engineering2023，17，10： | 0 |
| 2 | Oxidized Black Phosphorus Nanosheets as an Inorganic Antiresorptive Agent显示文摘Black phosphorus(BP)is a newly discovered two-dimensional material that has promising applications from bioelectronics to biomedicine.However,facile oxidation of BP leads to changes in surface chemical composition and physical properties,often being referred to as the degradation process of BP.Degradation products of BP nanosheets,namely,oxidized BP nanosheets(oBPNSs),are routinely considered as by-products without many uses.Herein,we found that oBPNSs displayed excellent osteoclastogenesis inhibition effects without impairing cell viability.In contrast to the classic antiresorptive bisphosphonate drugs,oBPNSs showed a different mode of action by suppressing the maturation of osteoclasts.Bone resorption assays,osteoclast actin ring analysis,and tartrate-resistant acid phosphate activity assay results indicated that oBPNSs suppressed receptor activator of nuclear factor-κB(NF-κB)ligand(RANKL)-induced osteoclastogenesis in a dose-and oxidation-dependent manner.Transcriptomic and proteomic analyses indicated that oBPNSs inhibited the activation of the NF-κB signaling pathway and phosphorylation of mitogen-activated protein kinase(MAPK)in differentiated osteoclasts,as confirmed by Western blot analysis.Our results suggest that oBPNSs might be potential antiresorptive nanomaterials to treat osteoporosis. | Yun Xu Jianbin Mo Wei Wei Jing Zhao | 2021 | CCS Chemistry2021，3，4： | 0 |
