Strong, flexible, and highly conductive cellulose nanofibril/PEDOT:PSS/MXene nanocomposite films for efficient electromagnetic interference shielding

“…3b, the characteristic peaks of cellulose Iβ at 3432, 2898, 1716, 1629, 1428, 1162, 1114, and 898 cm −1 are observed in the spectrum of pure CNF. [51][52][53][54][55][56][57][58][59][60][61][62]83,[88][89][90] In addition, CvO stretching from ester groups on CNF is found at 1716 cm −1 . 63 The typical bands of PEDOT:PSS can be found in the spectrum of pure PEDOT:PSS.…”

Nanocellulose/two dimensional nanomaterials composites for advanced supercapacitor electrodes

“…In addition to the characteristics of cellulose, nanocellulose also demonstrates large aspect ratio, and specific surface area, excellent mechanical strength, and good chemical reactivity ( Dai et al, 2017 ; An et al, 2019 ; Li et al, 2019 ; Li et al, 2020a ; An et al, 2020 ; Wang et al, 2020a ; Dai et al, 2020 ; Si and Xu, 2020 ; Liu et al, 2021e ; Wang et al, 2021 ; Wang et al, 2022 ). According to the morphological structure, nanocellulose can be divided into three classes: bacterial cellulose (BC), cellulose nanofibers (CNFs), and cellulose nanocrystals (CNCs) ( Ostadhossein et al, 2015 ; Tayeb et al, 2018 ; Xie et al, 2018 ; Xie et al, 2019 ; Chen et al, 2020a ; Chen et al, 2020b ; Lu et al, 2020 ; Li et al, 2022a ). Nanocellulose could be mixed with other conductive materials as electrode materials for supercapacitors ( Kang et al, 2012 ; Li et al, 2018 ; Nie et al, 2018 ; Zhang et al, 2018 ; Li et al, 2020b ; Liu et al, 2020b ; Li et al, 2022b ).…”

Effects of taxifolin from enzymatic hydrolysis of Rhododendron mucrotulatum on hair growth promotion

“…Many researchers use hydrolysis to change the structure of a compound ( Xie et al, 2018 ; Xie et al, 2019 ; Du et al, 2019 ; Du et al, 2021a ; Lu et al, 2019 ; Yang et al, 2019 ; Wang et al, 2021 ; Wang et al, 2020 ; Liu et al, 2020a ; Xu et al, 2020b ; Xu et al, 2020c ; Liu et al, 2021a ; Liu et al, 2021b ; Liu et al, 2022a ; Xiong et al, 2021a ; Xiong et al, 2021b ; Liu et al, 2021e ; Liu et al, 2021f ; Ma et al, 2021 ; Zhang et al, 2021 ). For instance, acid hydrolysis and enzymatic hydrolysis are used to separate sugars ( El-Zawawy et al, 2011 ; Jang et al, 2012 ; Chen et al, 2016 ; Dai et al, 2020 ; Dai et al, 2017 ; Liu et al, 2017b ; An et al, 2020 ; An et al, 2019 ; Li et al, 2020 ; Li et al, 2019 ; Liu et al, 2020b ; Du et al, 2021b ; Du et al, 2022 ; Xu et al, 2021b ; Xu et al, 2022 ; Liu et al, 2022b ; Liu et al, 2022c ; Liu et al, 2022d ; Liu et al, 2022f ; Li et al, 2022 ). Compared to acid hydrolysis, enzymatic hydrolysis is an environmentally friendly method, can be performed under mild reaction conditions, and does not require expensive corrosion protection equipment and neutralization after hydrolysis ( Fan et al, 2012 ; Liu et al, 2017a ; Liu et al, 2017b ; Chen et al, 2020 ; Lu et al, 2020 ; Xu et al, 2020a ; Xu et al, 2021a ; Liu et al, 2021c , 2021d ; Liu et al, 2022e ).…”
