| 1 | Elastic Aerogels of Cellulose Nanofibers@Metal–Organic Frameworks for Thermal Insulation and Fire Retardancy显示文摘Metal–organic frameworks(MOFs)with high microporosity and relatively high thermal stability are potential thermal insulation and flame-retardant materials.However,the difficulties in processing and shaping MOFs have largely hampered their applications in these areas.This study outlines the fabrication of hybrid CNF@MOF aerogels by a stepwise assembly approach involving the coating and cross-linking of cellulose nanofibers(CNFs)with continuous nanolayers of MOFs.The cross-linking gives the aerogels high mechanical strength but superelasticity(80%maximum recoverable strain,high specific compression modulus of^200 MPa cm3 g−1,and specific stress of^100 MPa cm3 g−1).The resultant lightweight aerogels have a cellular network structure and hierarchical porosity,which render the aerogels with relatively low thermal conductivity of^40 mW m−1 K−1.The hydrophobic,thermally stable MOF nanolayers wrapped around the CNFs result in good moisture resistance and fire retardancy.This study demonstrates that MOFs can be used as efficient thermal insulation and flame-retardant materials.It presents a pathway for the design of thermally insulating,superelastic fire-retardant nanocomposites based on MOFs and nanocellulose. | Shengyang Zhou Varvara Apostolopoulou‑Kalkavoura Marcus Vinicius Tavares da Costa Lennart Bergstrom Maria Stromme Chao Xu | 2020 | Nano-Micro Letters2020，12，1： | 10 |

| 4 | Wood-inspired engineering materials显示文摘Nature continues to serve as inspiration for the design and fabrication of high-performance materials [1,2].The structural and compositional features responsible for e.g. the high hardness and fracture toughness of nacre,tooth enamel and other biominerals have served as a bench- mark for the structural design of hard and strong materials [3].Wood has been utilized by humankind for millennia for protection,construction,energy and for cultural and religious objects.The hierarchical and cellular structure of wood and the structure-property rela- tions of the constituents and their assemblies:e.g. cellulose,hemicellulose and lignin,has been the focus of intense research efforts and resulted in advances in the fabrication of wood-based functional and structural high- performance materials [4,5]. | Lennart Bergstrom | 2018 | Science China Materials2018，61，12： | 1 |
